    Vigilantism against Migrants and Minorities (2019)
    Taylor & Francis | Routledge
    Details
    Publication Date: 2023-09-12
    Description: This edited volume traces the rise of far right vigilante movements – some who have been involved in serious violence against minorities, migrants and other vulnerable groups in society, whereas other vigilantes are intimidating but avoid using violence. Written by an international team of contributors, the book features case studies from Western Europe, Eastern Europe, North America, and Asia. Each chapter is written to a common research template examining the national social and political context, the purpose of the vigilante group, how it is organised and operates, its communications and social media strategy and its relationship to mainstream social actors and institutions, and to similar groups in other countries. The final comparative chapter explores some of the broader research issues such as under which conditions such vigiliantism emerges, flourishes or fails, policing approaches, masculinity, the role of social media, responses from the state and civil society, and the evidence of transnational co-operation or inspiration. This is a groundbreaking volume which will be of particular interest to scholars with an interest in the extreme right, social movements, political violence, policing and criminology.

    Are We Comparing Yet? (2019)
    transcript Verlag - Bielefeld University Press
    Details
    Publication Date: 2024-03-26
    Description: Debates about the possibility of an open culture – or indeed about the possibility of an open debate about the openness of culture – often turn on questions of standards. But since no benchmark can be absolute, judgement is a proliferation of comparisons. Through a series of case studies in everyday and academic comparison (literature, history, politics, philosophy), Haun Saussy calls out the typical vices of comparison and proposes ways to unseat them. For however much it is abused, distorted, and manipulated, comparison retains an essential link to the idea of justice.

    The Politics of Affective Societies (2019)
    Bielefeld University Press | transcript Verlag - Bielefeld University Press
    Details
    Publication Date: 2024-03-23
    Description: Many claim that political deliberation has become exceedingly affective, and hence, destabilizing. The authors of this book revisit that assumption. While recognizing that significant changes are occurring, these authors also point out the limitations of turning to contemporary democratic theory to understand and unpack these shifts. They propose, instead, to reframe this debate by deploying the analytic framework of affective societies, which highlights how affect and emotion are present in all aspects of the social. What changes over time and place are the modes and calibrations of affective and emotional registers. With this line of thinking, the authors are able to gesture towards a new outline of the political.

    Frei, fair und lebendig (2019)
    transcript Verlag - Bielefeld University Press
    Details
    Publication Date: 2021-12-16
    Description: This book should give you courage. It unites meaningful thinking with a new way of acting. The goal: a free, fair and lively society. But the familiar has become deeply engraved in our minds, in our everyday lives, in the market and the state. Silke Helfrich and David Bollier reveal traditional ways of thinking and design a program for successful coexistence, a different understanding of politics and caring business. The focus is on commons practices. They show how we pursue common goals in diversity. Practically, houses and vehicles can be created in a similar way to Wikipedia. The book also suggests how to think like a "commoner". It offers a language for the world of tomorrow. It's not just changing the economy and politics - it's changing us.
    Description: Dieses Buch soll Mut machen. Es vereint ein beziehungsreiches Denken mit einer neuen Art zu handeln. Das Ziel: eine freie, faire und lebendige Gesellschaft. Doch das Gewohnte hat sich tief eingegraben in unseren Köpfen, in unserem Alltag, in Markt und Staat. Silke Helfrich und David Bollier legen überkommene Denkmuster frei und entwerfen ein Programm für ein gelingendes Miteinander, ein anderes Politikverständnis und ein sorgendes Wirtschaften. Im Mittelpunkt stehen dabei Commons-Praktiken. Sie zeigen, wie wir in Verschiedenheit gemeinsame Ziele verfolgen. Ganz praktisch können so Häuser und Fahrzeuge in ähnlicher Weise wie die Wikipedia entstehen. Das Buch stiftet zudem an, wie ein »Commoner« zu denken. Es bietet eine Sprache für die Welt von morgen. Es verändert nicht nur die Wirtschaft und die Politik – es verändert uns.

    Kulturpolitik in Thüringen (2019)
    Bielefeld University Press | transcript Verlag - Bielefeld University Press
    Details
    Publication Date: 2024-03-29
    Description: A comprehensive analysis of the ways, networks and structures of cultural politics on state level which shows that cultural politics currently experience a crisis concerning their purpose and structure that is inherent in the system.
    Description: Kaum ein Politikfeld ist so heterogen zusammengesetzt, normativ aufgeladen und von symbolischen Handlungen geprägt wie die Kulturpolitik. Über die Funktionsweise dieses Feldes liegen bislang nur vereinzelte politikwissenschaftliche Studien vor. Michael Flohr wählt das selbsternannte »Kulturland Thüringen« als Fallbeispiel, um Handlungsfelder, Praktiken, Governance-Formen und Netzwerke in der Kulturpolitik zu untersuchen. Die Analyse stützt sich auf eine umfangreiche qualitative und quantitative Datenbasis und belegt: Kulturpolitik befindet sich in einer systemimmanenten Sinn- und Strukturkrise.

    The AlpArray Seismic Network: A Large-Scale European Experiment to Image the Alpine Orogen (2019)
    Details
    Publication Date: 2019-12-05
    Description: The AlpArray programme is a multinational, European consortium to advance our understanding of orogenesis and its relationship to mantle dynamics, plate reorganizations, surface processes and seismic hazard in the Alps–Apennines–Carpathians–Dinarides orogenic system. The AlpArray Seismic Network has been deployed with contributions from 36 institutions from 11 countries to map physical properties of the lithosphere and asthenosphere in 3D and thus to obtain new, high-resolution geophysical images of structures from the surface down to the base of the mantle transition zone. With over 600 broadband stations operated for 2 years, this seismic experiment is one of the largest simultaneously operated seismological networks in the academic domain, employing hexagonal coverage with station spacing at less than 52 km. This dense and regularly spaced experiment is made possible by the coordinated coeval deployment of temporary stations from numerous national pools, including ocean-bottom seismometers, which were funded by different national agencies. They combine with permanent networks, which also required the cooperation of many different operators. Together these stations ultimately fill coverage gaps. Following a short overview of previous large-scale seismological experiments in the Alpine region, we here present the goals, construction, deployment, characteristics and data management of the AlpArray Seismic Network, which will provide data that is expected to be unprecedented in quality to image the complex Alpine mountains at depth.

    Analysis of the source parameters behaviour during the Val D'Agri test-injection (Italy) (2019)
    Details
    Publication Date: 2019-03-27
    Description: Recent advances in understanding induced earthquake mechanics are due to the new and high-quality observations from seismic signals, natural faults and laboratory experiments. The synergy of different approaches allows the acquisition of useful observations to understand the earthquake source process. In this study we investigate the source parameters behaviour of induced earthquakes recorded during daily injection tests in a wastewater disposal well in Val D’Agri (VDA, Italy). We choose this area because of its complexity and particularity. VDA is a Quaternary extensional basin located in the Southern Apennines characterized by a complex tectonic evolution, high seismic hazard and significant hydrocarbon exploitation. The basin hosts the largest onshore oilfield in Europe that produces oil and associated gas from low- porosity, fractured Cretaceous limestone. Wastewater associated to hydrocarbon production is reinjected into the Costa Molina 2 high-rate well (CM2) into an unproductive marginal portion of the carbonate reservoir at 2890-3096 m depth (b.s.l.). Initial injection tests were performed from 2 to 12 June 2006 with variable duration (from 4 to 32 hr) and hourly injection rate of 38 m3/hr. During the tests a maximum well-head pressure of 101 bar was measured. These tests induced a swarm microseismicity (69 events, ML comprised by 0.3 and 1.8) recorded by a high-performance local network run by INGV (Mc 0.4, 23 stations) that constitutes our testing data-set. We investigate the full moment tensors decomposing them in Double-Couple (DC), Isotropic (ISO) and Compensated Linear Vector Dipole (CLVD) components by using HybridMT technique. We obtain significant contribution of %ISO and %CLVD components that tend to increase with time. Also, we compute the moment magnitudes (that we compare with ML) and the static stress drops (by spectral analysis). Finally, we discuss each analysed source parameter as a function of the injection pressure curve in the geological/tectonic contest.

    AlpArray in Hungary: temporary and permanent seismological networks in the transition zone between the Eastern Alps and the Pannonian basin (2019)
    Details
    Publication Date: 2019-03-07
    Description: In the last few decades dense large-scale seismic networks showed their importance in studying the structure of the lithosphere and the upper mantle. The better understanding of the Apennines–Alps–Carpathian–Dinarides system is the main target of the AlpArray European international initiative in which more than 50 institutes are involved. The core of AlpArray is the AlpArray Seismic Network (AASN). With its 􏰖 600 broadband seismic stations ( 􏰖 280 of which are temporary) the AASN is, so far, the largest passive seismic experiment in Europe. The MTA CSFK Geodetic and Geophysical Insti- tute, as a Core Member of the AlpArray project, contributes to the AlpArray Seismic Network with its entire permanent network as well as with 11 temporary broadband seismic stations deployed in Western Hungary. Three additional station equipment were provided by the Swiss-AlpArray SINERGIA program. The average station distance together with the permanent stations is around 40 km in the area of interest. The temporary network has been installed between December 2015 and July 2016 and the planned operation period is 3 years. In this paper we describe the characteristics of the 29 per- manent and temporary stations, introducing not only the equipment, but the location, housing and geological setting, as well. We present median power spectral density curves in order to characterise the noise conditions at each station.

    Effects of depth and initial fragment weights of Gracilaria gracilis on the growth, agar yield, quality, and biochemical composition. (2019)
    Details
    Publication Date: 2021-05-19
    Description: Gracilaria gracilis farming was conducted in the Bizerte lagoon (North of Tunisia) at two depths (0.5 and 2.5 m) using various initial fragment weights (5, 20, and 40 g) in order to investigate the alga growth, agar yield, and quality. IR spectra of agar were performed in comparison to the commercial one. Moreover, the proximate biochemical composition of seaweeds was investigated. The results showed that the highest daily growth rate and agar yield were recorded at 0.5 m, using 5 g as initial fragment weight (5.98 ± 1.98% day−1, 14.87 ± 1.91% dw, respectively). Maximum gel strength was 356.67 ± 15.25 g cm−2 at 2.5 m using an initial weight of 20 g. Gelling and melting temperatures varied from 34.33 ± 0.57 to 35.50 ± 0.57 °C and from 77.00 ± 1.00 to 85.00 ± 0.50 °C, respectively. IR analysis revealed that some spectra were similar, while others were different. The highest dry matter (22.68 ± 1.77%) and ash content (35.25 ± 0.02% of dw) were recorded at 2.5 m, using initial weights of 20 and 5 g, respectively. The maximum carbohydrate and the crude protein contentswere obtained at 0.5m, using 5 g as initialweight (9.52 ± 0.36 and 5.83 ± 0.7% dw, respectively). The highest R-phycoerythrin content was recorded at 0.5m(0.050 ± 0.007 mg g−1 dw), while the maximum of total lipid content was recorded at 2.5 m with initial weight of 5 g (3.58 ± 0.63% dw). Our findings indicated that growth and biochemical composition of G. gracilis depend on the depth and initial fragment weights.

    Estimation of awareness of fisheries students with regarding to benefits of fish consumption (2019)
    Details
    Publication Date: 2021-05-19
    Description: Regarding the importance of increment of fish per capita consumption in the health of the society, it is important to understand the benefits of fish and its nutritional value to prevent and treat some diseases. The research aimed to investigate the awareness of fisheries students about the benefits and fish nutritional value to promote the fish consumption in their household and future occupational in society. Students' information questionnaire of two universities on the content of lipids and proteins, vitamins, minerals, amino acids, fatty acids, reasons for fish consumption and their therapeutic effects were collected in 2017. After analyzing Chi-squared and Friedman test and scoring the correct answers, 64.4% of the students did not affect the consumption of their household fish consumption after their acceptance. Fish per capita consumption of students was calculated to be 23.3 kilograms. In their view, Iodine is the richest element in fish to prevent goiter. Cardiovascular disease, Alzheimer and cancer are prevented using fish consumption. With a mean score of 7.53 and a score of 18 at most, 16.4 % of students had awareness of the benefits of fish. The result of the study revealed the need for more serious training and more attention to the fish benefits and nutritional value of the fisheries course curriculum, so that they can be better promoters for the fish consumption among people and their families.

    Organotropism of organic and inorganic mercury in fish from the Vistula Lagoon, Poland. (2019)
    Details
    Publication Date: 2021-05-19
    Description: Our paper presents the results of a study on the concentrations of total (Hgtotal), organic (CH3Hg+) and inorganic (Hginorg) mercury in freshwater fish from the Vistula Lagoon, coastal waters of the Baltic Sea. Mercury assays were performed on tissues (muscle, skin, gills) and internal organs (heart, spleen, liver, gastrointestinal tract, gonads) of pikeperch, common roach, and common bream. The distributions of Hgtotal, CH3Hg+, and Hginorg depending on fish species, tissue, or organ and bioaccumulation in tissues and biomagnification in the trophic chain were determined. Interspecific and intraspecific differences in mercury concentrations occurred in fish tissues and organs. Muscles of pikeperch, bream and roach accumulated the highest concentration of CH3Hg+, Hginorg dominating in the gastrointestinal tract of bream and roach. The concentration gradations of Hgtotal and CH3Hg+ depending on fish species were as follows: pikeperch 〉 common roach 〉 common bream. For Hginorg, the gradations were as follows: common bream 〉 common roach 〉 pikeperch. The type of food was a determining criterion for the distribution of mercury forms in the tissues and organs of the fish studied, and quantifiable confirmation of this was the different values of the L:M coefficient (Hginorg in the hepatic tissue : CH3Hg+ in muscle). Differences in Hgtotal, CH3Hg+, and Hginorg concentrations in fish tissues and organs were linked with the food the fish consume, their position in the trophic chain and biomagnification in the food chain.

    Multi-scale imaging of the Main Pamir Thrust faults within the framework of CaTeNA project – Climatic and Tectonic Natural Hazards in Central Asia (2019)
    GFZ Data Services
    Details
    Publication Date: 2024-02-23
    Description: Abstract
    Description: We propose to investigate the structure and evolution of the Main Pamir Thrust (MPT) with a high-density seismological array. The MPT, with its surface expression along the east-west trending Alai Valley, marks the northern boundary of the Pamir. The Alai Valley, separating the Pamir and the Tien Shan, constitutes the last vestige of a formerly continuous basin that linked the Tarim and the Tajik Basins. The MPT manifests itself as a place of high seismic activity with frequently occurred disastrous earthquakes. The array is about 50 km long, consisted of 90 three-component geophones (stations G?? and C??) and 10 Trillium-Compact seismometers (stations T??), and equipped with 100 CUBE dataloggers. We will construct a high-resolution receiver function profile to image the MPT and accurately locate the local earthquakes associated with the MPT. Funded by BMBF, within the framework of CaTeNA project – Climatic and Tectonic Natural Hazards in Central Asia. Waveform data are available from the GEOFON data centre, under network code 7A and are embargoed until Jan 2024.

    Description: Abstract
    Description: Extensive passive seismic monitoring was carried out between September 2017 and September 2018 over the Los Humeros geothermal field in Mexico. This experiment, in addition to several geophysical, geological, and geochemical surveys was conducted in the framework of the European H2020 and Mexican CONACyT-SENER project GEMex for a better understanding of the structures and behavior of the local geothermal system currently under exploitation, and for investigating future development areas. 25 broadband stations (22 Trillium C-120s and 3 Trillium C-20 PH) recording at 200 Hz, and 20 short period stations (Mark L-4C-3D) recording at 100 Hz comprised the network which is sub-divided into two sub-networks. An inner and denser (~1.6-2 km inter-station distance) pseudo-rhomboidal array (27 stations) was laid out to cover the producing zone and retrieve local seismicity mainly associated to injection and production operations, and to comply with beamforming of ambient noise and time reverse imaging techniques. An outer and sparser (~5 km minimum spacing) array was placed at around 30 km radius surrounding the inner network, and was mainly dedicated to larger scale imaging techniques, such as seismic ambient noise tomography, and regional earthquakes tomography. The GEMex project is supported by the European Union’s Horizon 2020 programme for Research and Innovation under grant agreement No 727550 and the Mexican Energy Sustainability Fund CONACYT-SENER, project 2015-04-68074.

    Non-Double-Couple Component Analysis of Induced Microearthquakes in the Val d’Agri Basin (Italy) (2018)
    Details
    Publication Date: 2018-03-23
    Description: In recent years it has become accepted that earthquake source can attain significant Non-Double-Couple (NDC) components. Among the driving factors of deviation from normal double-couple (DC) mechanisms there is the opening/closing of fracture networks and the activation of pre-existing faults by pore fluid pressure perturbations. This observation makes the thorough analysis of source mechanism of key importance for the understanding of withdrawal/injection induced seismicity from geothermal and hydrocarbon reservoirs, as well as of water reservoir induced seismicity. In addition to the DC component, seismic moment tensor can be decomposed into isotropic (ISO) and compensated linear vector dipole (CLVD) components. In this study we performed a careful analysis of the seismic moment tensor of induced microseismicity recorded in the Val d'Agri (Southern Apennines, Italy) focusing our attention on the NDC component. The Val d'Agri is a Quaternary extensional basin that hosts the largest onshore European oil field and a water reservoir (Pertusillo Lake impoundment) characterized by severe seasonal level oscillations. Our input data-set includes swarm-type induced micro-seismicity recorded between 2005-2006 by a high-performance network and accurately localized by a reservoir-scale local earthquake tomography. We analyze two different seismicity clusters: (i) a swarm of 69 earthquakes with 0.3 ML 1.8 induced by a wastewater disposal well of the oilfield during the initial daily injection tests (10 days); (ii) 526 earthquakes with -0.2 ML 2.7 induced by seasonal volume changes of the artificial lake. We perform the seismic moment tensor inversion by using HybridMT code. After a very accurate signal-to-noise selection and hand-made picking of P-pulses, we obtain %DC, %ISO, %CLVD for each event. DC and NDC components are analyzed and compared with the spatio-temporal distribution of seismicity, the local stress field, the injection parameters and the water level in the impoundment. We find significant NDC components and abrupt temporal variations in the DC and ISO components that appear linked to the extremely variable parameters of the injection tests into the disposal well.

    Structural inheritance controlling active crustal deformation in the Val d’Agri area (southern Apennines, Italy): new insights from finite element modelling (2018)
    Details
    Publication Date: 2019-01-18
    Description: The availability of a large amount of surface geological data and subsurface information gathered by the oil industry, together with seismic and geodetic data, allowed us to define and analyse the active structures in the Val d'Agri area of the southern Apennines. Taking into account that the study of interseismic deformation can be significant to identify locked fault areas that can potentially slip, in this study we present 2D elastoplastic finite-element models to reproduce interseismic characteristics of the study area. This hosts the largest Europe's onshore oil field and is characterised by an active extensional tectonic regime, as inferred from earthquake focal mechanisms and fault slip data from late Quaternary structures. Based on high-quality seismic profiles tied with deep well logs, we constructed a detailed geological section across the study area. Outcropping units are dissected by numerous brittle structures that formed at various stages during the tectonic evolution of the Apennines, while the deep ones are dominated by deeply rooted major faults. The rheological behaviour has been constrained by the reconstruction of the thermal structure of the fold and thrust belt, using available information from the foreland Apulian Platform and from temperature data from a series of wells. Starting from the geological model, we reproduced interseismic deformation by means of finite-element numerical modelling, varying boundary conditions and unlocking different fault segments. Our numerical models provide new insights into the controversial and widely debated active tectonic setting of the Val d'Agri area, confirming the major role played by structural inheritance and reactivation processes. In fact, recent low-magnitude seismicity tends to illuminate fault segments consisting of pre-existing reverse faults reactivated as normal faults in the present-day stress field. These long-lived, mature fault systems occurring in the buried Apulian Platform carbonates (and underlying basement) represent major brittle structures that cumulated displacements of up to a few kilometres over geologic time. As a result of their reactivation within the late Quaternary extensional stress field, these long-lived crustal structures are capable of nucleating also moderate- to large-magnitude earthquakes. The decoupling between deep and shallow structural levels, and the different inherited structures affecting them, explain the apparent contrast between the subdued surface expression of active fault systems and the known occurrence of large magnitude seismic events in the study area, thus reconciling apparently contrasting geological and geophysical constraints.

    Details
    Publication Date: 2021-05-19
    Description: Striped grey mullet (Mugil cephalus) is a marine fish with high commercial value and widespread distribution. The grey mullet and some other mullets can be found in saltwater, brackish and fershwater habitats at tropical, subtropical and also temporal climates.This species is suitable for aquaculture worldwide due to living in wide ranges of water temperatures and salinities, acceptable growth rate, suitable food conversion ratio, marketability, suitable species for polyculture with shrimps, marine fish and even with freshwater carps. The grey mullet is farming in different countries such as Italy, Northern Africa countries ( Egypt), occupied Palestine, India, Pakistan, Japan, Hong Kong, Taiwan, Vietnam, Indonesia, coastal countries of southern pacific ocean and Hawaii. Ten thousands of fries of this species (average weight and length of 280 mg and 28.3 mm respectively) imported in March 2008 from Egypt. The wild fries colleted from surrounding natural waters of Alexandria. After finishing the quarantine steps, they stocked in four earthern ponds (each with 2500 m2) located at the Gomishan shrimp educational centre at late march in 2008. At the first year of culture the densities were 5000 and 10000 individuals per hectar and each treatment with two replicates. At second years densities changed with 2000 and 2500 ind./hec. and each of traetments divided fishes with average primary weights of 80 and 115 grames. The fries and fish feeding begins in April when the water temperature rise above 18 °C and it cut in fall when the temperature goes under 20°C. They fed twice a day at 8 AM and 2 PM and the amount was 5-7 percents of the fish existent biomass in each ponds. They fed with dry formulated feed made of Mahdaneh Karadj Company (Danso dry feed) both the first and second years of farming. The feed prepared for carps feeding and containded 23±2 % crude protein, 10 ±2 % crude lipid, about 7 % crude fiber, 15 % ash, 40 ±2% carbohydrates and with energy content of 4000±200 kcal/kg. After seven months culture period the average weight and length of fish in treatment 5000 ind./hec. were 113.7 gr and 21.1 cm respectively and in treatment 10000 ind./hec. the average weight and length were 86.6 gr and 19.6 cm respectively. At first year the average survival rate in different treatments was 77 percent. The average FCR in treatments 5000 and 10000 ind./hec. were 3.4 and 3.9 respectively. At second years after six months culture the average weights in pond no. 9 (with primary weight 115 gr and density 2000 ind./hec) , pond no. 10 (with primary weight 80 gr and density 2000 ind./hec) , pond no. 11 (with primary weight 115 gr and density 2500 ind./hec) and pond no. 12 (with primary weight 80 gr and density 2500 ind./hec) calculated as 476.6 ,338.1, 366.5 and 440 gr respectively. The average survival rate and FCR were 93 % and 3.1 respectively. Ponds no. 9 and 11 (fish stocked with primary weight 115 gr in densities both 2000 and 2500 ind./hec) selected as the best economic efficient treatments.

    Details
    Publication Date: 2021-05-19
    Description: This investigation conducted for evaluation Silo (Cylindrical) Fish Tanks as an applicable method for aquaculture of Rainbow trout (Oncorhynchus mykiss). Current research was designed in two practical phases as accidental experiments through 3 treatments and repeats of which stocked by three Rainbow trout (375 gr) densities as 75, 100 and 125 fish/m3 in 9 silo fish tanks (2 m3). For better understandings of the silo performance method, concrete circular fish tanks (similar volume) considered as controls and stocked as similar fish densities as silo tanks. The duration of the first phase of experiment was 150 days. The second phase of the experiment was determined for evaluating two proposed silo type (Inlet and outlet in bottom side / Inlet from bottom and outlet in upper side). In this stage, proposed silos (stocked by fish of 294 gr weigh) tested for rearing trout for 30 days. Water supplied from two surface wells after some aeration operations. Stocked fish were fed by pellets made by Fish Feed Chineh Company (Ltd) in Iran. Feeding operation conducted according to the recognized manuals by consideration of water temperature, fish weight and biomass. Meanwhile, biometry operation conducted in 10 days intervals while fish were anaesthetized. In addition, water quality was determined by daily measurements. According to the results of the first phase of experiment, there were significant variations on Growth rate, survival rate, FCR, FCE and SGR through the cultured organisms in silo tanks compared to the circular tanks. Meanwhile, according the results of an economic study on this survey, the fish culture in silo tanks showed significant economical and profitable in compare to controls. In additions, the second phase of experiment showed better aeration conditions in silo tanks when inlet water supply from bottom side and outlet located in upper side. Because of the fine distribution of fish in silo tanks and more usage of depth by this method, fish culture would be an applicable and profitable technique in narrow lands and slopes through the mountains area. The maximum stocking rate recorded more than 100 Kg fish/m3 in silo tanks.

    Peptone production from marine and culture wastes by commercial enzymes for bacterial culture media (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Thirty to 40% of total fish catch is converted to waste. Using different methods of hydrolysis of the protein can be recovered of fish waste and increase the amount of protein efficiency. In this study, the four enzymes Alcalase , protamex , pepsin and trypsin were used for hydrolysis of four fish species including common carp (Cyprinus carpio) , silver carp (Hypophthalmichthys molitrix) , grass carp (Ctenopharyngodon idella) and the Big head (Hypophthalmichthys nobilis). The effects of pH, temperature and hydrolysis time on the rate of hydrolysis were studied on soluble proteins and degree of hydrolysis (phase I ). In the second step, proximate factors of peptone been evaluated and eventually replace commercial peptone media MRS ( Lactobacillus plantarum , Lactobacillus delberuki , Lactobacillus casei , Streptococcus thermophilus ) and TSB ( Listeria monocytogenes, two species of Bacillus and Pseudomonas, Streptococcus faecium) and the optical density of bacteria at different times were compared with control samples . Results showed that the highest degree of hydrolysis and soluble proteins were referred to alcalase and protamex, pepsin and trypsin respectively. The highest value of hydrolysis, in all treatments, was attributed to grass carp and silver carp, common carp and big head respectively. The best pH and temperature for alcalase, protamex, pepsin and trypsin 8.5and 55, 7.5 and 55, 3.5, 37, 7 and 37 respectively. Best time to achieve the highest degree of hydrolysis and soluble protein was 90 minutes. Qualitative analysis showed that the highest and lowest amounts of protein and fat in the treatment of alcalase (about 70 % protein and less than 0.5 % fat ) and protamex, pepsin and trypsin was then . The results of bacteria culture showed that the highest percentage growth of lactic acid bacteria was referred to Streptococcus thermophilus and Lactobacillus casei had the lowest rate of growth. In other bacteria, Pseudomonas and Bacillus species were the highest percentage of growth and Listeria monocytogenes and Streptococcus faecium respectively. In all treatments, alcalase had the best results and the peptone prepared from fish waste grass carp had the best condition for growth of used bacteria. It seems that the initial substrate , the parameters used such as temperature, pH, and enzyme hydrolysis time , have a significant effect on the quality of peptone and protein content in the final product is determined value of protein for culture of bacteria.

    Fish culture experiments with Abramis brama orientalis in earthen pond to diversify aquaculture fish composition in Iran (2018)
    Details
    Publication Date: 2021-05-19
    Description: On two consecutive culturing period, the Caspian sea Bream fingerling average individual weight 30g stocked in a fish pond at the rate of 3000 unit per ha to rear through mono-culture method. Also in the other test carp pond fish comprised of 70% bream, 20% silver carp and 10% grass carp totally 4000 unit per ha Stocked to examine poly-culturing with bream species. The test replicated in second year by the same manner but the only difference was the weight of stocked bream fries which were 4g on average. Chemical fertilizer and chicken manure applied as warm water fish culturing technique demand. Carp grow out feed pellet supplemented to the ponds. Fish health, water quality and growth rate monitored. The minimum water temperature were 9 ֯C and maximum 33 ֯C recorded. Dissolved O2 = 5-7 mg/l, pH = 7-8.62 in the first year by mono-culturing method the bream achieved 200 gr by species on average. But with poly-culture system the bream gained 250g weight. Also individual species reached 580g. In second year test the pond with mono-culture method bream with the weight of 180 g produced. With poly-culture method the target species accomplished 221 g on average, also 300g appeared in the yield, Bream mortality didn't occurred during culturing. The experiment demonstrated poly-culturing of bream with Chinese carps by semi-intensive method produced satisfactory results. We suggest the bream could be enhanced in the list of fish species of Iran and able to promote sustainable aquaculture development.

    Publication Date: 2021-05-19
    Description: In order to study the Inheritance of Microsatellite Markers in the hybrid of Chalcalburnus chalcoides and Vimba vimba persa in the Southern part of the Caspian Sea, hybridization between the species was carried out during spring (2009) in Shahid Ansari reproduction and culture workstation. 30 samples from the produced larva and also small piece of dorsal and pectoral fin of their parents were collected and stored in pure ethanol (96%) and transferred to the biotechnology of the Caspian Ecology Academy. DNA was extracted from fin samples of the parents, whilst the whole F1 progeny was used to isolate the DNA by Phenol-chloroform method. Quantity and quality of extracted DNA was determined using 1% Agarose electrophorus. DNA was used for PCR ampilification of 10 microsatellite loci. The amplifications were run on 6% Polyacrylamid electrophorus. The present study showed that 7 out of 10 markers were polymorphic and variated between the parents. Goodness of fit to the Mendelian inheritance ratio was determined by X2 analysis. 4 primers were segregrated according to Mendelian expectations at a significance level of P 0.05. Based on UPGMA dendrogram (Nei, 1978) two different clusters were obtained in which Chalcalburnus chalcoides and hybrid were in the same cluster but Vimba vimba persa was in the other. It seems that Vimba vimba persa is a joint ancestor for these two. High heterozygosity presence in parents and their F1 shows the high potential of genetic variety in Chalcalburnus chalcoides and Vimba vimba persa which from the aquaculture management and conservation view is important and considering the high genetic variety in their hybrid, the hybrid has the sufficient potential for race improvement.

    Publication Date: 2021-05-19
    Description: The "fisheries and aquaculture industry innovation system" is one of the subsystems of Agricultural innovation system (AIS), also has many characteristics of that system .Since this section contains most of the components and AIS institutions, it can be examined as a part of the national innovation system. Due to the structure of the innovation system in the fishery system, a set of functions and institutions of this system are most important .It is therefore important that the system be analyzed and by reviewing the existing state institutions and functions of this system, the main problems and challenges identified. Understanding of the institutions and functions of fishery innovation system and analyze its problems and provide an improved model for fishery innovation system, is most activity in shaping major policy innovation in fishery sector. This step is very important to conduct innovative activities in the fishery sector. In this study, using a system perspective, the current status of the various factors affecting fishery development was assessed and the main drivers and challenges and solutions to improve the detection and analysis was provided. The results show that during the past eighty years, a number of research centers and educational institutions in the public sector have been developed .but this system, despite having considerable institutional capacity, is still in the middle stages of institutional development. In these years, the policy approach was linear, not system approach, so little attention has been to the development of science and technology intermediary institutions, coordinator organizations, venture capital funds, and the institutions of technology transfer ,particularly in the public sector.

    Details
    Publication Date: 2021-05-19
    Description: The Common carp is the most important culture fish in the word, that can be consider as domestic fish. The Common carp of Caspian Sea is one of the economic fish, that have some morphenological differences, resistance in salt water and better quality in meet with domestic once and for using this fish in culture system, it is necessary to establish genetically parameters especially the heritability for selection purpose. The present study have been started from 2007 and lasted 3 years. The breeders were collected from the Gomishan station in south-east of Caspian Sea by fisherman and stocked in S.Rajaei fish restocking center and propagate based on the routine propagation technique in this farm. For heritability estimation a factorial crosses by 7×7 fish were done. Therefore, the fingerlings of 49 crosses were achieved, that kept first separately fiberglass tank and then in pond separately. Weight and length of fish were choice for heritability estimation. The average weight of juvenile common carp in 3 sampling stage of 90, 180 and 360 days, were 5.9, 35.7 and 84.7 gram and length of 9.6, 14.7 and 19.2 cm respectively. The heritability estimation for weight was 0.26 and length 0.25. Selection response based on selection difference by collection the more average breeders among their progeny were 36.4 g that means by selection every generation, there is about 4 percent improving in fish weight.

    Study on propagation and breeding of Hamoun fish (shizothoraxzarudnyi) to one gram weight in earthen pond (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Hamoun fish, Schizothorax zarudnyi, is an indigenous species of the eastern waters of Iran, which is exclusively found in this region. However recently drought occurrence in the Chahnimeh reservoirs (a semi natural water body) making them vulnerable to extinction. As an appropriate action to address this problem and according to the 3 side contract between Italian Government – UNDP - Islamic republic of Iran Government and the Italian government financial support to reduce poverty in the Province of Sistan-Baluchestan through the reinforcement and dissemination of aquaculture activities the project was developed at the Hamoun Research Unit by the Chahbahar Fisheries Research Center to record the breeding normative of 1 g weight larvae for restocking and other researching purposes. 331 broodstocks of the indigenous species Shizothorax zarudnyi weighing 800-2450 g were collected from the Chahnimeh reservoirs in early autumn, 2006. From 5/3/2007 ( the project is supported and communicated on 2010) , Ovulation was stimulated with three stimulators; pituitary extract (3-6 mg kg-1 body weight), GnRH-A (20-30 mg kg-1 body weight) and anti dopamine (10-15 mg kg-1 body weight) that was given in 2-3 doses to breeders. Of 169 injected breeders , some were injected On mid March of 2007 (12-13 ºC water tempreture) responded to the injection 25% ,while the rest were injected On April of 2008 (14-16 ºC water tempreture) responded to the injection 65%. In the present project of 167 breeders 82 were female and 87 male. Totally 30 female breeders released their eggs in different stages. 20 female breeders released their eggs completely, 3 breeders released half of their eggs and 7 released 1/3 of their eggs. The male breeders just injected in the final dose of hormontrapy and all were ready for releasing sperms however the ovulation in female breeders occurs between 353-428 h ºC and after the final dose of injection. Ripe eggs were stripped from the females and fertilization was done by the dry method. Fertilized eggs were transferred to veis incubators and troughs. Incubation period for eggs differs and larvae hatch out after about 910 days at an average water temperature of 12.5 °C. Maintained at 13-14 °C, complete absorption of yolk sac in Shizothorax zarudnyi larvae occurred after 5-8 days. Larvae were fed with a mixture of powdered milk and egg yolk in this stage followed by decapsulated Artemia cysts and nauplii of Artemia and then on formulated starter diets used for carps . Because the ponds were not ready, larvae were maintained in troughs for about ten days before they were transferred to two 1200 m2 earthen ponds where they reached a body weight of about 1 g. They were then handed over to the Iranian Fisheries department in the region. Larvae were fed with the starter feed SFCO in the earthen ponds. About 350 thousand larvae were stocked in two earthen ponds. Based on the results of present study and other studies we may conclude that artificial breeding in Schizothorax can be successfully achieved at 14-16 ºC in flow through systems using hormone therapy (combination of GnRha and anti dopamine) and larvae could be easily cultured in earthen ponds. However this species exhibits lower growth rates as compared to carps its high expenses could have an important role in economical feasible.

    Publication Date: 2021-05-19
    Description: Limnological studies of the Zarrineh River have been performed in order to identify physicochemical and biological characteristics of this river. Water samples from 14 sites along the river length were examined monthly during a year. The results indicated the river was polluted by Saghez and Miandoab Cities sewage to the extent of poly saprob , the extent of pollution at other sites was within the limits of oligo saprob or meso saprob. The results also showed that all dissolved and mineral compositions in this river was safe for drinking but iron concentration and water hardness in the terminal sites near the Urmia Lake are higher than EPA standards for drinking . This can not, however, pose serious problem for warm water fish culture activities. Domestic sewage seem to be the most important pollution source to this river. Although the self-purification capacity of this river seem to be high but large number of polluting sites along the river exceed this capacity.

    Single cell protein Production from culture and marine fish wastes (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The alarming rate of population growth has increased the demand for food production in third-world countries leading to a yawning gap in demand and supply. This has led to an increase in the number of hungry and chronically malnourished people. This situation has created a demand for the formulation of innovative and alternative proteinaceous food sources. Single cell protein production is a major step in this direction. SCP is the protein extracted from cultivated microbial biomass. Algae, fungi and bacteria are the chief sources of microbial protein that can be utilized as SCP. Produced proteins from these microbes have various nutrition values. SCP is the manufacture of cell mass using microorganisms by culturing on available agriculture, industrial wastes and fisheries by products. Fish wastes due to high protein are the most important substrates for SCP production. In this study, SCP production was done from Silver carp and tuna fish wastes (head, tail and vise versa) and cooked water of canned tuna factories. The used microbes were six genus and species of yeasts include Candida utilis, Saccharomyces cereviceae, Rhodotorula, Khyveromyces marxians, Zygosaccharomyces rouxii and Bacillus subtilis and B.licheniformis. The examination was done in bench scale and CSTR bioreactor (Continuous Stirred Tank Reactor). The effects of various parameters such as pH, temperature, time, supplemented substrates, method of inoculation of microbes, rpm were evaluated. Changes of microbial growth and protein contents were tested by using Optical Density (OD) and Makrokjeldal methods respectively. In end of examination, produced protein were extracted and lyophilized. The results showed that protein percentage in bacterial protein was than yeast protein but wet percentage in bacterial protein was low. Production value produced from tuna fish wastes was higher than (30-45 g/l) to Silver carp wastes (25-29 g/l) and cooked water (10-15 g/l). By adding supplemented substrates, production value has been increased. Candida utilis, in comparison other yeasts, has high activation. B.licheniformis has also had more activation than Bacillus subtilis. The results of the effect some parameters on fermentation showed that yeasts and Bacillus in pH= 5.4 and 32oC and pH=6.9 and 35oC were better than growth pH=6 and 25oC and pH=6.5 and 30oC respectively. Time of fermentation in batch and bioreactor was 54 and 21 hours respectively. High rpm has been caused increasing of microbial growth in bioreactor. The conclusion showed that with optimizing of the growth condition such as some parameters (pH, temperature, substrates and so on) produced SCP with high efficiency. However, produced SCP should be exanimated with other specific tests such as amino acid and fatty acid profiles, minerals, nucleic acids and so on. After full examination, this SCP as probiotic could be used in fish and poultry feed.

    The Study of nutrition and feeding position of shrimp, cultured in IRAN (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The culture of Iranian Shrimps began in Bushehr in 1372. Early the green or the pink tiger shrimp (Penaeus semisulcatus) which were found in most habitats of the Persian Gulf and Oman Sea were considered in breeding and reproduction, but due to reproduction difficulties, it was rather replaced by the Monodun imported species, then the production of the white shrimp Metapenaeus affinis and Then P.merguensis in some southern areas of the country such as Hormozgan has began in small scale,but none of these species couldn't meet the economical needs of the consumer society and they were not indelible and dominant enough in the shrimp aquaculture industry of the country until breeding of Indian White Shrimp (Fenneropenaeus indicus) has began in large scale in the provinces of Khuzestan and Bushehr, which are seen as the heart of shrimps reproduction and breeding, and in Hormozgan and Sistan. the incidence of white spot viral syndrome (White Spot Syndrom Virus) led to the import of the western white leg shrimp from the USA (P.vannameii) by the Iranian Fisheries Research Organization (IFRO) in 1383, at the present all southern and northern breeding farms of the country (fundamental measures has been carried out in line of shrimp reproduction in Gorgan province in 1386) has put the breeding of this shrimp species as the single breeding species at top of their agenda. The subject of feeding the breeding shrimps is widespread and regarding to the non-proprietary species there are still some species which contain high protein than the other species in studying the different shrimp species requirements. In Iran due to the scarce factories producing the shrimp's food, the alimentary compound of the breeding shrimps during industrializing years of this type of breeding even after the non-aboriginal western white leg shrimp species being inclusive was stable and through different biological processes including: Naplies which feeds from its yalk and by entry into zoa stage start eating only small-sized phytoplankton. And by entry into the stage between zoa and mysis it feeds from phyto and zooplankton simultaneously and entering the post-larva stage it stars sarcophagi. and after 15 post-larva stage entering the growth and transition stage to earthen ponds feeding by concentrated industrial foods in large and small packages depending on young and adult mouth and due to feeding requirements of every stage the alimentary compound is nearly as follows: Digestible protein, energy, fat, carbohydrates, vitamins and minerals will start and the final product will be released in market Or they will be used in the later years of laying eggs and feeding for brood stock. In feeding section the details of every stage and their food's nutritional needs at each stage and will be fully described.

    Surveying Most Efficient Method for Culture of Gammarus as a Live Food in Aquaculture (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: In order to produce a procedure for production of a natural food source for fish, amphipod Gammarus (Crustacea) were noticed, which inhabits spring-brooks in wide areas of Fars province, especially in its cold regions. Five typical habitats of these animals were firstly identified, and some of their important physical and chemical factors, including depth, current velocity, width of habitat, dissolved oxygen concentration, pH and electrical conductivity were measured monthly for one year, May 2000-April 2001. Some other factors of water quality like calcium, magnesium, and total hardness, sulfate, chloride, and potassium ions concentration were measured just once. Artificial culture were designed and conducted in three steps. At step 1, using 10 individuals in four 1000 cc beakers, firstly the effect of three different sources of water, the city pipe water, ground water (a well), and water from one of the typical springs were investigated measuring survival time in no-food condition. Then, selecting spring water, the effect of three different diet including fresh lettuce leaves, decaying willow leaves, and fish pellets on the specimen s survival were recorded. At step 2, using 400 individuals in four 40 liter glass tanks containing and supplied with fresh lettuce leaves as food source, firstly the probable effect of artificial illumination, and then, introduction of microbial flora from the habitat spring were compared to a control group. In both steps, water was aerated continuously. Finally at step 3, an experimental pond (600cm×200cm, with 50cm depth) was made and 2000 adult amphipods were introduced. Animals were fed by fish pellet. During the experiment, water temperature, dissolved oxygen concentration, and pH, along with the new population density and total body length were measured in consequent repeated times. All the data were processed by calculation of means, standard deviations, and statistical tests including Analysis of Variance and Duncan test. Results showed that in natural habitats current velocity ranged 2.5-100cm/s (Mean=29.3), water depth ranged 5-60cm (mean=25.3), water temperature ranged 11.2-18.4°C (Mean=14.4) dissolved Oxygen ranged 3.45-13.33 ppm (Mean=7.5), pH ranged 6.5-8.8 (Mean7.6), and electrical conductivity ranged 200- 760µs/cm (Mean=357), in the period of our investigation. Range of variation between five habitats was 26.55- 56.64ppm (Mean=43.48) for Chloride ion concentration, 7.20-16.80ppm (Mean=12.77) for sulfate ion, 50.50- 85.77ppm (Mean=63.00) for Calcium hardness, 99.50-246.22ppm (Mean=138.59) for Magnesium hardness, 150-332ppm (Mean=201.6) for total hardness, and 0.15-0.30ppm (Mean=0.25) for Potassium ion concentration. Culture experiments showed that spring water is significantly the only reliable source compared to the well water and city pipe water, and lettuce fresh leaves and decaying willow leaves had showed significant differences compared to fish pellet in feeding amphipods in closed and limited spaces of laboratory containers. Also, artificial photoperiod had a significant negative effect in laboratory situations which their water temperature was not controlled on low ranges, due to a rapid and huge algal growth. Adding microbial flora, which may has benefits for amphipod s better growth, showed no significant effect on their survival in tanks. Culture in pond proposed that the process of growth and reproduction acts continuously through the whole year, but it seemed that new generations did not reach the adulthood and sexual maturation until the coming spring.

    Breeding and reproduction of grey mullet (Mugil cephalus L.) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Mazandaran and Gorgan provinces have temperate climate, thus they have more potential for aquatic animal culture. There are thousands hectare of salt and useless lands in adjacent to Caspian Sea. As these areas have provided a favorable back ground for aquatic animal culture. As a result, the successful results obtained from imported gray mullet (Mugil cephalus) culture project in north climate, it has demonstrated that the gray mullet has a good biocharacteristic for culturing in pond enclosure environment and in different aquatic conditions (fresh water, brackish water and salt water). From 1998 until 2001, the broodstock yield and gray mullet artificial propagation projects were performed by fisheries research center of Mazandaran in Ghomishan prawn culture station in adjacent to Caspian Sea (East north of Mazandaran Province). This investigation executed during two stages (phases). At first stage, the goal of this project included the survey of possibility available about matured fish as well as induction of final maturation and artificial propagation for producing of broodstock and larva. In addition, in this way, we will obtain new information about gray mullet propagation and culture as marine species. We introduce mass production in aquaculture. At present research, the possibility of broodstock yield and artificial propagation of gray mullet have investigated by gray mullet fingerlings imported from Hong kong and then they have cultured in earth ponds of Ghomishan areas during five years (1994-1998). In order to broodstock production in spring 1998, two earth ponds (0.5 hectare) were prepared. 100 specimens of fish stock (1-2.5 kg weight average and 5 years of age) placed in each pond. For providing of suitable water and nutrition, fish were fed by food containing rich protein (40%) with 3-5% body weight and maintained in water with 30-35 ppt salinity. The survey of sexual maturation was performed by sampling of sexual glands through year. There were four stages in dominant female broodstocks. This survey indicated that oocytes have emerged stage 1 (immature) from March to June, stage 2 (yolk vesicle) in September and stage 4 (yolk globule) in October. Three stages (first, second and third) of yolk formation in oocytes will occur but these stages take place in October, December and January respectively. It's obvious that oocytes will progress into the end of third stage (yolk formation) and then their growth was arrested. Ovum with 600 m diameter was observed when the water temperature declined less than 18 c and day time was short (from middle autumn to middle winter), on that time, fish were induced by hormone because lack of final maturation and ovulation, there fore, natural spawning was not occurred in pond condition. Furthermore, artificial propagation of mugil cephalus was occurred by hormonal induction. Hormonal induction was utilized by inject of many hormones (LHRH, Cph, HCG). Using different components of hormones and also their different doses obtained the best results from broodstock that the average ovum diameter was about 600 m. Several types hormones which were injected into gray mullet with two or several intermittent (24 h intervals) along with 20-25 c temperature and 30-35 ppt salinity. This condition can provide stage 4 maturity for fertilization. Totally (as whole), three intermittent fertilization was necessary for exiting of larva, larva production in first, second and third intermittents that were 2000, 2500 and 300 specimens respectively. Larva fed on chlorella algae and rotifera and they have maintained for 14-15 days. The results of obtainable research indicated the possibility of gray mullet broodstock production in cultural condition, artificial propagation and larva production. This research took place for the first time in north climate of Iran.

    Description: This project was carried out in order to determine the hatching conditions and laboratory culture methods of Fairy Shrimps ( Phallocryptus spinosa). Physico- chemical factors and phytoplankton of natural habitat of this organism was investigated in Khasellou region around Azarshahr – East Azarbaijan province. The results showed that occurance and growth of fairy shrimps in their habitates were beginning from early Aprill and their survival was decreased with increasing temperature, precipitation and increasing the salinity of their culture medium. Then they disappeared. Their habitat phytoplankton contained 3 phylla and 10 genera, from which green algae enjoyed the greatest density in May. The pool salinity was around 20-17 g/l , when metanauplii was observed in early spring. In the pool containing and without fairy shrimps the oxygen concenteration was high (9 mg/l) and low (2.9 mg/l ) , respectively . In 9 prawn ornamental fish genera, feeding with fairy shrimp showed a significant higher fecundity and hatching percentage compaired to manual diets (cow liver, spinach). In all groups fed with fairy shrimp the duration of spawning time were reduced from 15 to 8-10 days and the color was enhanced. The means of cyst number per captured female also, cyst , decapsulated cyst and Naupilli diameters were mesured 142.9±19.0 cysts , 273.2 ± 4.9 µ , 242.4± 3.8 µ and 542.6 ± 27.0 µ., respectively . The hatching rate was increased by reducing temperature and salinity of their culture mediums from 25 to 15 ◦ C , and 28 to 18 g/l, respectively.The highest hatching was observed on 5 th day at 15 ◦ C and 18 g/l (5, 33 %). In addition, low but multiple hatching was observed. Therefore , water temperature and salinity affected hatching rate in this species.The hatching success of Phallocryptus spinosa cysts was beter when collecting cysts together with dry sediments of their habitat without separation sensetive cysts . In addition to cold keeping and freezing, the hydration – dehydration method caused more diapause deactivation for hatching induction. The laboratory results revealed that the survival of fairy shrimps were highest at 15 ◦ C (42%) and lowest at 25◦ C (26%), respectively. Also, their life was inhibited in 30◦ C.In different salinities, the mean survival rate were 26% (Salinity = 15 g/l) and 20% (Salinity = 25 g/l), respectively. The mean survival percentage of Phallocryptus spinosa cultured in natural habitat water (64.3%) was higher than aerated tap water (23, 3 %). Also, feeding with Nanochlorepsis caused higher survival rates. On the other hand, Beakers yeast caused higher mortality rates. Therefore , regarding to relatively high sensitivity of these species to physico – chemical and nutritional conditions of their culture medium, it is better to culture these species with expantion of their natural habitat in order to preserve their biodiversity , culture and increase stocking density with regard to environmental considerations .

    Application of microsatellite markers to determine populations of the Persian sturgeon (Acipenser persicus) (2018)
    Details
    Publication Date: 2021-05-19
    Description: The objective of this study was to analyse the population genetic structure of the Persian sturgeon (Acipenser persicus) in Sefidrud and Gorganrud rivers watershed based on the characterization of microsatellite markers during 2006 – 2008. 100 samples of Persian sturgeon were collected from two regions. Four microsatellite loci ( Ls 68 , Spl 168 , Spl 173 and Afu 68 ) were analyzed for the molecular characterization of this species which resulted in polymorphic patterns. DNA bands were analysed using Biocapt and GenAlex software package. A total of 109 alleles were observed of which the maximum number of alleles (17) were found in Spl168 locus which belonged to sturgeons from Sefidrud river,s watershed and the minimum number of alleles (10) in Ls68 locus belonging to the sturgeons from Gorganrud river,s watershed. Results of microsatellite analysis revealed that the differences between samples of two regions were not statistically significant (p〉0.05), neither for the average number of alleles per locus nor for observed heterozygosities. The calculated Fst and Rst between two regions was 0.07 and 0.17 showing that the genetic difference was significant (p〈 0.01). Samples from Sefidrud river,s watershed in Spl173, Afu68 and Spl168 loci and samples of other regions in Afu68 and Spl168 loci were at Hardy-Weinberg equation. The genetic distance was calculated as 0.4 which represents a significant genetic difference between samples of two studied areas. I n conclusion, this study suggests that the Persian sturgeons in two regions of the southern part of the Caspian Sea are genetically differentiated, therefore fisheries management of these unique stocks for restocking and conservation of gene pools is highly recommended.

    Description: Nowadays, seaweeds have many uses in food industry, weaving, pharmacy, medicine, biotechnology and so on. Many efforts has been made to regenerate seaweeds in artificial media in order to carry out genetic engineering process since 1970. In this study we have tried to establish a proper method for sterilization and tissue culture of brown seaweed, Sargasopsis zanardinii, in 1/2PES, PES and 2PES media. After sterilization, the explants of the seaweed were cultured in liquid and solid media. Consequently turgidity in margin of explants, longitudinal cell division and formation of hairy strands, and microcallous formation were showed by explants which cultured in PES and 2PES solid media. After transporting from liquid to solid media, juglike bodies were formed on the surface of solid PES media and then some brown strands were grown from these bodies that finally were flattened. None of these results was obtained from 1/2PES media.

    Description: To understand the change in fish consumption behavior of Tehran citizens (Iran), in the year 2005, an investigation was conducted using questionnaire. Using independent random method, 316 families covering all 22 districts of Tehran were selected. The results were combined with that acquired in the year 2001 to develop marketing programs. We used Fridman, K2 tests for nonparametric statistics and Z (normal distribution) and Phi Cramer index for analysis. The results showed that the quality and freshness of the products and the hygienic state of the distributing places had the highest effects on purchase. Also, the price and packaging had the same priority as in the year 2001. No significant relationship was found between income level of the families and their fish consuming tendency. Comparing the two years of study, we found that 16.6% more people preferred packed food in the year 2005 while per capita consumption had increased from 2.8 to 3.46kg. With the information on production date and health license already available on the products, the consumers demanded dietary contents. Considering the increase in marine fishery products, the families tended to consume more of the farmed aquatics with the live selling of rainbow trout being preferred the most. The behavior of consumers and their decisions to purchase fishery products in this period depended on production directions and economic development strategies which indicated positive aquaculture development programs in the country. We recommend continuing current policies regarding marketing factors. The results also showed that uncertainly about freshness and health of the products is the main reason for purchase from the representative fishery stores. The results shows more research and advertisement can improve awareness about packing advantages and its role in decreasing wastes and creating more added values.

    Production of all-female Rainbow Trout (Oncorhynchus mykiss) using sex-reversed males and investigation of their growth parameters in the first year of culture (2018)
    Details
    Publication Date: 2021-05-19
    Description: Possibility of producing all-female rainbow trout (Oncorhynchus mykiss) using neomale stock were investigated in Kelardasht hatchery. To do this, we compared the fertilization, hatching rate and growth parameters of progeny in the first year of culture. Histological studies of gonads showed that progenies produced by mating sex-reversed males and normal females were totally female. Eyed-stage egg, hatching and early survival rate in all-female population were 90:69 %, 97.36 %, 91.49 % and in mix sex population were 70.24 %, 98.22 %, 90.73 %, respectively, showing no significant differences (P〉0.05). Lack of maturation in the first year cultured fish led to the identical growth parameters in mix sex and all-female groups (P〉0.05). Results showed that use of sex-reversed males can be one of the best and successful methods of producing all-female populations.

    Details
    Publication Date: 2021-05-19
    Description: Iranian Fisheries Institutes in the north of the country are involved in the reproduction, culture and release of five species of sturgeon fingerlings into the Caspian Sea. The species are Acipenser persicus, A. guldenstadti, A. nudiventris and A. stellatus and Huso huso. Shahid Beheshti Fisheries Centre as the first commercial hatchery started its activities in 1972 in Rasht, Guilan Province of Iran. The centre achieved a production ceiling of 21.6 million fingerlings in 1997 and increased it to 24.5 million fingerlings in 1998. It is anticipated that the centre will achieve a threshold of 45 millions fingerlings in the next few years. During 1997-2002, the centre has increased its extent from 377 hectares to 887 hectares For Huso huso production, 17 specimens were caught in 1998, of which 10 were injected that produced 1.08 million fingerlings and in 2002, the number of caught and injected Huso huso were 29 and 21 respectively, that resulted in production and release of 2.4 million fingerlings. A number of 1062 A. persicus breeders were caught in 1998 of which 581 individuals were injected with hypophysis extract resulting in production and release of 22.5 million fingerlings. Of 538 injected individuals from among a total 802 breeder fish caught in 2002, a number of 12.3 million fingerlings were produced and released into the sea. The catch for Acipenser stellatus in 1998 was 193 breeders that produced 623000 fingerlings. In 2002, the catch increased to 290 breeders, of which 67 received injections to produce 1.3 million fingerlings. A total number of 0.67 million fingerlings of A. guldenstadti was produced in 1998 which was increased to 1.78 millions in 2002. For Acipenser nudiventris, the number of fingerlings produced in 1998 was 0.4 which was increased to 1.56 millions in 2002.

    An investigation of the effects of differing protein levels on growth indices WG, RGR, FCR, FCE and PER in cultured crayfish (Astacus leptodactylus) (2018)
    Details
    Publication Date: 2021-05-19
    Description: Knowledge of nutritional requirements and especially protein levels is needed to produce strong and larger freshwater crayfish in controlled conditions. This has not been available for the miniature size crayfish culture. Hence, an eight-week experiment was conducted on miniature size crayfish in three treatment groups each with three replicates receiving a diet that contained 25%, 30% and 35% protein levels with isocaloric digestible energy (DE) 3500 kcal/kg. A number of 540 miniature crayfish with a mean weight 100± 12mg were randomly selected and partitioned into nine tanks containing 200 liters of freshwater 70% of which exchanged daily. The fish were fed at 25% of body weight five times daily at 6, 10, 14, 18 and 22 hours using pellets 0.1, 0.2 and 0.4 mm. Nutritional responses in tern of weight gain, PGR, FCR, FCE and PER were compared among the groups using one-way ANOVA. The test showed a significant increase in the indices such as WG and PER in response to increased protein level (P〈0.05). FCR, FCE and PGR show a significant increase using 20% protein level while using 30 and 35% protein levels did not produce significant results (P〈0.05). The test revealed a significant difference between treatments 1 and 3 (P〈0.05) but not between 1 and 2.1 conclude that the treatment 3 produces more reliable results.

    Description: We investigated the effects of Vibrionaceae family of bacteria as probiotics in the process of growth and survival rate of shrimp during propagation stages. Bacterial flora were extracted from seawater, culture farms, shrimp culture farms and sludge of private propagation farms. Different bacteria such as Vibrio alginolyticus (serotype 1-4), Vibrio splendidus I, Vibrio fluvialis II, Vibrio anguillarum I, Vibrio costicul, Vibrio vulnificus, Vibrio nereis, Vibrio campbelli, Vibrio natriegens, Vibrio proteolyticus, Vibrio pelagius II Vibrio fischeri, Aeromonas hydrophila, Aeromonas schuberti, Aeromonas salmonicida, Aeromonas veronii were isolated, identified and lyophilized. These bacteria were used in different experiments on shrimp life cycle stages while the shrimps were being fed on live food such as Chaetoceros, Skeletonema and Tetraselmis algae. Vibrio alginolyticus (serotype 1) with 107 cells/ml increased proliferation of Tetraselmis sp to 71 % in 6 days compared to the control experiment. Also Vibrio alginolyticus (serotype 4) with 105 cells/ml increased Tetraselmis sp. production to 389% in 6 days compared to control. Vibrio splendidus I was also found to be able to increase shrimp fork length in postlarvae stage 3 up to 23% as compared to control. Vibrio alginolyticus and Vibrio fischeri increased survival, fork length and body weight of green tiger shrimp in postlarvae stage significantly (P 〈0.05).

    Fungal infection of culture shrimp in Bushehr, southern Iran (2018)
    Details
    Publication Date: 2021-05-19
    Description: In an attempt to assess the shrimp culture management in the south of Iran, we collected samples of the cultured shrimp in two farms during the year 1999, and examined them macroscopically and microscopically. We identified 16 species of fungus infecting the shrimps mostly in outer body layers and the gills and also detected hemolymphatic infection with the fungus in a few cases. In all cases, the Penicillium species was the most abundant fungus and the ponds showed a significant difference in the amount of fungal flora contaminating them (p〈0.05). We found that the contaminating fungus species were all opportunistic, appearing as a result of stress occurred to the cultured shrimp, water muddiness, low dissolved oxygen concentration and putrefying food left unused at the bottom of the culture ponds. These were all considered to be related to the pond management.

    Changes of dissolved oxygen and transparency in shrimp culture ponds (Hormozgan Province - Tiab) (2018)
    Details
    Publication Date: 2021-05-19
    Description: Dissolved oxygen and transparency are two main factors in management of shrimp culture. In this regard, three Indian white shrimp culture farms in Tiab region were selected and in each farm three ponds were studied randomly. Dissolved oxygen samples were collected two times per day (morning and evening) from surface and maximum depth of the ponds. The transparency of water was measured by secchi-disk daily, at 15:00 P.M. The Results showed that amount of dissolved oxygen in afternoon samples more than 3.5 mg/lit which is suitable for growth of shrimp but in morning time samples the level of Dissolved oxygen were unsuitable especially in ponds which were not equipped with any aerator. Also, the long-arm aerators showed higher and better efficiency than short-arm aerators. From point of transparency, the results showed that in the beginning of culture period, the transparency was high (more than 100 cm) and gradually decreased.

    Culture of Indian white prawn (Penaeus indicus) brooders from adolescent shrimps using natural diet in the captivity (2018)
    Details
    Publication Date: 2021-05-19
    Description: The shrimp farming success in the future will greatly depend upon increasing supplies of healthy and high quality seed for stocking ponds. The limited and inconsistent availability of wild shrimp postlarvae together with an urgent need of establishing selective breeding programs, increased the interest in captive broods of penaeids. Many investigations have been carried out on several shrimp species world-wide. This study has been conducted on 3 shrimp groups since September to July 1999 in Bandar-e-Imam southwest Iran. The wild group (SPB) prepared from jask area and the pond group (POB) prepred from artificial ponds upon. harvesting them as marketable size have been investigated. 2 groups were exposed to natural diets consisting of squid and artemia biomass in same conditions using 12 m33 concrete tanks. Stocking density was 2 piece/m2 (1F:1M). Half part of the pond bottom covered by fine sand to reduce the stress where the other part has been used for feeding. Daily ration given in 3 times by satiation method. Also reproductive performance of wild gravid brooders (WLB) were recorded as a control group. 2 examined groups well and around 30% of POB females successfully ripened an produced eggs and nauplii. Almost all males of both groups were matured. Data showed fecundity is highly correlated to the TL and W of the brooders by positive trend. Considering the TL, W, fecundity and nauplii production the WLB brooders are significantly (P〈0.05) higher than 2 other groups, while the SPM brooders are significantly (P〈0.05) higher in hatchability. Meanwhile the survival rate from nauplii to postlarvae stage was around 30% for SMP brooders. On the other hand the growth parameters (TL,W) of the marketable size of the shrimps produced from SMP brooders were significantly (P〈0/05) higher than those produced from WLB group. Since the fecundity is important by increasing the brood size thus the data suggest the superiority of the SPM brooders.

    Publication Date: 2021-05-19
    Description: This study has been carried out to evaluate the possibility to culture shanak (yellow fin seabream: Acanthopagrus latus) fish in the ground pond. The study including two experiments. In the first experiment two commercial available feeds (403 as shrimp food and F.F.T as trout food both produced by Chineh company) are used to evaluate the growth performance of the bream Juvenile produced artificially in the Bandar Imam Mariculture Research Stationin weghing 2.72- 3.54 g. To perform the first experiment 6 ground ponds each with 0.25 ha area are used as replicates 3 ponds randomly allocated to each food. 5000 in dividual juvenile fishes are stocked in each pond. After 116 days rearing period well growth performances are achieved for both foods with no significant difference (P 0.05) between them, although better growth performances are observed for F.F.T food. The final weight (WE), SVR ,FCR and SGR of shanak for F.F.T food respectively were 23.29 ± 11.14, 95.98% ±0.78, 1.39 ±0.26 and 3.47±0.23 where for 403 food were 22.08±9.95 , 89.67%±8.75 , 1.53±0.12 and 3.25±0.33 respectively. In the second experiment in which only trout food was used the target was to examine the growth parameters of shanak juvenile in a full rearing period (198 days) in the ground pond. Juvenile fishes with 36.53 g were used with same methods adopted for the first experiment. The final weight of 206.3 g is achieved by 89.35% SVR and 1.92 of FCR. Results of this experiment showed that the growth quickly improved with fast rate along with the increment of temperature and salinity up to 25ºC and 14 ppt respectively. There after by the raising the temperature and salinity more than 25 ºC and 14ppt respectively the growth reduced.

    Publication Date: 2021-05-19
    Description: This project was performed to evaluate the qualitative and quantitative operation of hatcheries and shrimp culture Sites in Hormozgan province during years 2004-2006. All the active hatcheries including one hatchery located in Bandar-e-Jask, Three hatcheries in Bandar-e-Kohestak, one hatchery in Bandar-e-kolahi and two hatcheries in Qeshm island also three shrimp culture sites including Tiab-e-Shomali, Tiab-e-Jonubi and sayeh khosh were surveyed. The Information about scientific and technical persons, employments, productions, important problems and also situation of costs and net were recorded in special forms. Results were analyzed by descriptive statistics. Results revealed that about 50% of the hatcheries located in Hormozgan province are closed through the different problems such as, failure of customer, failure of a distinct plan for post larvae producing, high coast of producing parameters and so on. Results also revealed that only 7.1% of farms located in sayeh khosh area, about 40.2 % of farms located in Tiab-e-Shomali and 62 % of farms located in Tiab-e-Jonubi areas are active. The two later areas have established about ten years ago. The most problems of most farm in Hormozgan province are the failure of sufficient knowledge of farms managers, high cost and low quality of shrimp foods manufactured by huge factories and low cost of cultured shrimps. Final, it can be said that problems of hatcheries are depended to shrimp farms problems. If problems of farms be did, problems of hatcheries will be did.

    Details
    Publication Date: 2021-05-19
    Description: Rutilus kutum is one of the most important economic fish species of Iranian costal of Caspian Sea. This species conducted more than 60% of fish caught in Caspian Sea annually, and more than 10 thousands fisherman engaged to its fishery. In present study, kutum fingerlings reared in two different densities include of 25 and 40 fish/m2 with mean weight of 17.5 ± 5.87 g. The period of test being planned 10 weeks and the test organism housed in circular concrete pools of 3 m3 capacity with flowing water and aeration in pools are supplied. The fishes feed by extrude food with 45% crude protein and 14% crude fat. After termination of the experiment, the result showed that weight gain performance, specific growth rate, condition factor, food efficiency rate and protein efficiency rate decreased, while food conversion ratio increased with rising of density, as their different was significance in two experimental treatments (p〈0.05). The kutum reared in low density showed significantly higher survival rate (SVR) (with 88.8%) than high density (with 76.9%) (p〈0.05). Based on the different observed effects of the density on growth and survival, it is recommended the use of a 25 kutum/m2 density for rearing by Caspian Sea water.

    Publication Date: 2021-05-19
    Description: Regarding the increase in world population and decrease in fish stock, there is an urgent need to aquaculture practices. Coldwater fish culture is aiming at production and providing a part of protein needs of the country and a way reaching to self- sufficiency and preserve the water resources. Recently, multi- purpose use of water resources potential and especially the rivers of west Azarbaijan, for example, construction of fish farms at upstream of permanent rivers in order to make optimum use of the resources and the increase in employment has been considered . The waste water of these pools is usually discharged into the rivers. Regarding to increased production per unit area due to water resources and cold water fish culture restrictions to use regional facilities and fish farm construction, it is nessacery to determine limits between 2 farms. In this study with the goal of evaluation of the impacts of trout farm effluents on water quality parameters of Pirdanan River, the factors of water current, temperature, pH, EC, TDS, TSS, DO, BOD5, NH3, N-NO2, N-NO3, TP P-PO4 according to standard methods were determined montly during 2014-2015 . Sampling sites were entrance, exit of Maroofi trout farm and the distances of 700, 1400, 2100 and 2800 m after the farm exit. Seasonal sampling of macro invertebrates from mentioned sites was conducted using stone leaching. The family and genus of macro invertebrates were identified using identification keys and abundance of macro invertebrate phylums for each site was determined. The results revealed that the values for water current, EC, TDS, TSS, N-NO3 were significant. the values of water temperature, BOD5, TDS, TSS, N-NO3- , N-NO2-, NH3, P-PO4- , NH4+, N-NH3 were increased in site 2 compare to site 1 in all months and gradually in the river and its self- purification were decreased. In this study, 4 phylums, 4 classes, 7orders and 14 families of macroinvertbrates were identified from Pirdanan River. Ephemeroptera had the highest abundance in site 4; while Diptera had the highest abundance in site 2 (exit). Regarding that most of Diptera macro invertebrates were from Chironomidae, so it can be concluded that site 2 was the most pollutant site and sites 5 and 6 were more suitable condition. Therefore, considering the physic- chemical factors and macro inverteberates indices, 2100 m from entrance, (site 5) is recommended compliance with veterinary organization rules and other conditions of aquatic engineering, environmental and water operation standards.

    Description: Marine polychaete worms living in different beds from coastal areas, so different cultures can be different effects on their development. The evaluation of this research initially, marine polychaete worms were collected in low tidal sea areas from Gulf Persian coast in Bushehr. During several stages of sampling do more than 2000 pieces of worm were taken and then transferred to Bandarga Shrimp Research Station (Iran Shrimp Research Center). So based on a observation the desired species identification (Perinereis nuntia). Then 400 pieces worm selected and transferred to tanks maintain immature worm (fiberglass tanks with dimensions of 2 × 2 × 0.5 m with 15 cm sand on floor). The results showed that even the worms (P. nuntia) in vitro reached sexual maturity able to spawn in captivity conditions and were absolute fecundity of 16010 ± 17630 eggs. After incubation eggs, larval culture into the plastic tank with 70 cm diameter, larval (1.5 to 2 mm) were introduced with density 2000 (pieces/m2). In this research used to three different beds ( tidal , filled with water all of time and wet bed ) with three different food types (food shrimp, seaweed and vegetable waste), so there were 9 experimental treatments. All experimental treatments harvested and estimate production in each of them after 270 days. The seaweed tidal treatment with amount of 21.17 g/m2 had best results and the all of wet treatments with 0 g/m2 was the lowest production. Compare of beds showed that the tidal treatments have significant difference with other beds in growth factors (e.g. mean weight, survival percentage and total production) (P〈0.05). And for effect of food kind on growth factors, the result of difference foods in tidal treatment were analyzed. According this mater any treatments have no significant difference together in growth factors (e.g. mean weight, survival percentage and total production) (P〉0.05).

    Description: The lack of sustainable management programs has resulted in the drastic decline of sturgeons stocks in the Caspian Sea in the past two decades. Legal catch quotas for all Caspian littoral states has dropped from 28500 tons in 1985 to 460 tons in 2007 while caviar production in the Caspian Sea during the same period decreased from 3000 tons to 70 tons. Caviar production in the I.R. of Iran dropped from 305 tons in 1985 to about 11 tons in 2007. The "Strategic and applied research planning for sturgeon management and conservation" was developed with the collaboration of academicians from universities, researchers, experts, fishery authorities and representatives of the executive government to maintain sustainable development and rational management of sturgeon stocks in the Caspian Sea. The preparation and development of this planning was carried out through 121 sessions (2100 person hours) A comprehensive report (375 pg) was prepared which was divided into five volumes; Volume I comprises an introduction, objectives, strategies and planning, present status of production and caviar harvest, catch and export quotas, revenue generated and release of sturgeon fingerlings, Volume II comprises analysis of the problem by constructing a problem tree with 8 broad categories to analyze 344 problems and an objective tree which is the hierarchic flowchart of objectives with 9 broad categories with 241 items, Volume III comprises a review and analysis of previous and ongoing research (414 projects) on different aspects of sturgeon during the past 40 years, Volume IV comprises prioritizing research objectives outlined by the objective tree and finally Volume V which prioritizes primary objectives for 14 executive and 10 research programs. On the basis of the evaluation of the present status and for the sustainable development and rational management of sturgeon stocks a strategic and applied research planning program was proposed and developed within the framework of three primary objectives; 1) Management and sustainable use of Caspian Sea resources (5 programs), 2) Rehabilitation and restoration of stocks (5 programs), 3) Development of aquaculture (4 programs). The applied research program for each proposed executive program was outlined in 10 programs, 42 comprehensive plans and 222 projects. The primary objective on management and sustainable use of Caspian Sea resources includes 5 programs, 14 comprehensive plans and 63 projects, while the primary objective on rehabilitation and restoration of stocks includes 4 programs, 16 comprehensive plans and 87 projects. The primary objective to address sturgeon aquaculture includes 1 program, 12 comprehensive plans and 72 projects. The impacts and outcome of each of these programs was determined and presented. It is evident that if the present situation persists, the catch figures for adult sturgeon specimens and caviar production in Iran will reach zero in 2021. But if concerted efforts are taken and the proposed strategic and applied research planning program is executed (commencing from 2009) we can put a halt to these declining trends. By producing sturgeon fingerlings to restore population abundances, by conserving and protecting them in the Caspian Sea and by conducting applied research we can produce 206.4 tons of caviar by the year 2033. Apart from harvesting caviar from the Caspian Sea we can also annually produce 3000 tons sturgeon meat and 60 tons farmed caviar starting from the year 2023. The total budget proposed for implementation of this program for a period of 14 years (2008-2022) is USD 2483 million. If this budget is allocated in time and the proposed strategic program is properly and totally implemented, we can not only save many sturgeon populations from extinction but also ensure job opportunities for 6000 fisherman, provide 1480 new job opportunities and annually produce 266 tons of caviar which will generate USD 4957 million.

    Possibility of the pond culture of Asian sea bass, lates calcarifer in Gwadar farm , Sistan & Baloochestan (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: In the present study, the possibility of marine culture of Asian sea bass in the shrimp earthen ponds located in the Gwadar r region (coastal area of Oman Sea, southeastern of Iran) was investigated. To this end, Asian sea bass frys reared for 7 months including 1 month nursery and 6 months growth-period. During the culturing periods, fish were feed ad libitum by various commercial rainbow trout diets based on fish growth stages. After nursery period, the average weight of 11.05±1.5 g and survival percent of 65 % were obtained for fish. During the growth-out period, the average weight increased continually from 31.4±4.7 g in late June to 252.1±30 g at the end of growth-out period in late Dec. Also, the highest values of monthly weight gain yielded during August, Sept and Oct when fish had the average weight range of (76.9±14.4)-(188.1±12.8) g. The values of monthly feed conversion ratio (FCR) were low and similar from July to Oct and then increased in Nov and Dec. The values of total monthly feed intake (FI) increased continually from July to Oct and then with a decrease in Nov, increased again in Dec. The values of survival percent after nursery and growth-out period were 65 % and 66% respectively. Also, the average of monthly FCR, FCR at the time of fish harvesting, total FI and total harvested biomass were 1.36, 2.5, 630.5 kg and 325 kg. in conclusion, the pond culture of Asian sea bass with marine water results appropriate survival and growth rates so that fish (11.05±1.5 g) obtained marketable weight (252.1±30 g) during 6 months culturing period. It seems that first-half of year in Gwadar area is more suitable for sea bass culture since this time periods results better FCR ( fed by rainbow trout feed) and has economic justification. Also, with regular sorting operation and providing of species-specific feed for Asian sea bass can increase the Production per Unit Area.

    Publication Date: 2021-05-19
    Description: The plan entitled "designing and establishment of ISO/IEC17025 in laboratories of three research centers affiliated to Iran Fisheries Research Organization" was carried out in the frame of three projects from March 2008 for about three years. Among the laboratories of The Persian Gulf ecological research center, the Caspian Sea ecological research center and the national shrimp research center 7, 5 and 3 laboratories were selected for accreditation, respectively. The quality manuals of the test laboratories were written following the requirements of ISO/IEC 17025. During the establishment of the system standardization of the test methods, calibration of the equipment, test methods validation and update and improvement of physical conditions of the laboratories were performed. The technical and quality management competence of the laboratories affiliated to the Persian Gulf ecological research center were evaluated by the auditors from DGA (the German Accreditation System for Testing Laboratories), which is signatory of ILAC (International Laboratory Accreditation Co-operation). But in the case of the two other centers, the laboratories were accredited by Iran Accreditation System (IAS). The laboratories officially accredited, after the successful completion of the accreditation process (including implementation of corrective actions for the detected non-conformities). Production of reliable results of the test methods from national and international scientific organizations' point of view as well as facilitation in development of bilateral and multilateral relations with them can be considered as the advantages of the system establishment. Moreover, exchange of the relevant scientific information and experiences among the researchers will be facilitated

    Effect of feeding times and stocking size on growth and food conversion rate of rainbow trout in brackish water (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: An experiment were conducted to evaluate The effect of feeding frequencies and stocking size on growth and feed conversion ratio (FCR) of rainbow trout (O. mykiss) in brackish water for 102 days. Three stocking sizes (10, 25 and 40 g/fish) of rainbow trout and three feeding frequencies (feeding fish twice, three times and four times per day) were examined as the same time. Fish were fed at a restricted feeding program according to the rainbow trout standard table in the definite times during the light period. The results showed that in the group with 10 g initial weight increasing the feeding frequency, some growth factors like final weight, daily growth, and weight gain. But the other factors such as food conversion rate (FCR) and specific growth rate (SGR) decrease. It means in this group (10 g) two times feeding per day is not enough for an acceptable growth rate. In the two other groups with (initial weight 25 and 40 g) although by increasing the feeding frequency, some growth factors a little increase but these differences in 95% level (p≤0.05) are not significant. Therefore in rainbow trout culture with initial weight at least 25 g two times feeding per day was enough. The results of carcasses analysis of fish, showed that by increasing the feeding frequency there were no significantly difference at 95% level between the body compositions in all of treatments. With connivance of feeding frequencies, the best FCR was in the group with 10 g initial body weight and there was not any significant difference in SGR. So according to the results, it suggests that fish should be stocked with 10 g initial body weight.

    Recognation of fishes in rivers and basin of Qom (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This study was carried out on rivers, basins & qanat of Qom region during the 1376-1378and Fish samples were taken from 2 permanent rivers (Qomrood ,Ghara_chag)& from some seasonal ones (Tagharood, Zavarian, Vesva, Biraghan). Also local fishes was followed in 100 qanats in the region and Random fish sampling was done in permanent river extension out of province. This study aimed to recognize different fish species in the province water reservoir and estimating the fisheries potential in the province. For fish sampling nets such as mashk, salik, hook and hand tailored were used. Electroshoker was not used at all. Results of fish recognition showed that fish samples belong to 12 species & 4 family of "cyprinidae", "Balitoridae", "cyprinodontidae" and "poecilidae".The qanat fishes of the montain (kahak, Khagestan) and pastora area (Ghanavat,jafarabad) included by two families of "cyprinid", "Balitoridea".In some qanat which were connected to rivers more species of fish and anotherAquatic animal were observed & sampled.At the and map of geographical distribution of local fishes was planned.

    Investigating limnologic factors of indoor and outdoor tilapia culture ponds and growth performance of the cultured tilapia (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Tilapia studies in Iran were begun since 2008 and different aspects of tilapia aquaculture in are researched. In the present study, limnologic factors of indoor and outdoor tilapia culture ponds, also growth performance of the cultured tilapia were investigated at the National Research Center of Saline Water Aquatics, during the culture period of 2016. Water temperature, dissolved oxygen, pH, salinity and ammonium concentration were measured. Depth of water transparency, the composition and frequency of plankton and macro benthos of the earth ponds were studied. Total length and weight of fish were measured to evaluate growth performance. In the earth ponds, the ranges of minimum and maximum of water temperature were 16.6-27.5°C and 20.5-31°C. The range of dissolved oxygen was 2.11-10.19mg/l in the morning and 7.06-14.64mg/l in the afternoon. PH was recorded 8.97-10.9 in the morning and 9.04-11.00 in the afternoon. The depth of the water transparency was 40- 105 cm. Water salinity was 7.94-8.82 ppt. The concentration of NH4+ changed from less than 0.05 to 0.4 mg/l. The frequency of phytoplankton and zooplankton was 2050-2848 and 269-101 per liter, respectively. The dominant phytoplankton and zooplankton were chlorophytes, diatoms and rotifers. The abundance of macrobenthos was 3467-558/m 2 and the dominant group were chironomids. Pearson 2-tailed correlation between the amounts of factors including temperature, salinity, dissolved oxygen, pH, NH4+ , length and weight of farmed fish in earth ponds showed a direct significant correlation between pH value against ammonium concentration, and total length against body weight of the fish, also between pH against water temperature and total length of the fish. There was a reversed significant correlation between the dissolved oxygen against water temperature and pH (p 〈0.05). In indoor tanks, the range of water temperature was 29-24°C, dissolved oxygen 1.65-8.38mg/l, pH 9.37-7.25, water salinity 7.12-7.7ppt, and ammonium 0.16-0.5 mg/l. Pearson 2-tailed correlation between the amounts of factors including temperature, salinity, dissolved oxygen, pH and ammonium with length and weight of fish in ponds showed a direct significant correlation between the length and weight of the fish body with each other, the amount of salinity against pH, salinity against total length and body weight. Also, there was a reversed significant correlation between the amount of dissolved oxygen against water temperature, pH and the total length of the fish.

    Publication Date: 2021-05-19
    Description: This research was carried out to determined water reuse effects on growth indices of rainbow trout. For this reason 4 groups includes: control (with use of 100% fresh water), Test 1(rearing with use of 30% recycled water (with physical filtration) and 10% fresh water), Test 2(using of 10% recycled water (with physical filtration) and 30% fresh water), Test 3(using of 100% recycled water) was done. Fish stock of each groups were done with 62 fish in each square meter and average weight (15±1.5).The Growth index, SGR,CF, FCR, SR between different groups in each month was calculated and determined. In this research comparison the average of month growth increasment between different groups indicated that significant decrease of growth in test groups with control group and also 1 and 2 groups with 3 group (p 〈 0.05). There were not considerable differences to comparison this factor between groups 1 and 2(p 〉 0.05). To comparison FCR, SR, MR has shown a significant difference between different groups to each other (p 〈 0.05). These results shows that with increasing the replacement of water in rainbow trout culture ponds with recycled water cased significant decrease in SR and CF and significant increase in MR and finally decrease in production and density per unit area (p 〈 0.05).
