    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.

    Seismic Recordings for SMARTIE1: Seismic Monitoring And Research of Wind Turbine Induced Emissions 1 (2019)
    GFZ Data Services
    Details
    Publication Date: 2023-02-08
    Description: Abstract
    Description: SMARTIE1 is a joint seismological experiment of the Karlsruhe Institute of Technology (KIT) and the Leipzig University. We installed in total 36 seismic stations as ring-like and profile-like measurements near to a single wind turbine (WT) at the Fraunhofer Institute for Chemical Technology (ICT) in Pfinztal, SW Germany, for 21 days. The main goals of this project are a better understanding of a single WT as a seismic source and the development of propagation models for the WT-induced seismic signals, depending on the geological properties. Waveform data are available from the GEOFON data centre, under network code X8 (under CC-BY 4.0 license according to GIPP-rules), and are embargoed until Jan 2020.

    One year of seismic records of an array installed on a taiwanese ridge (2019)
    GFZ Data Services
    Details
    Publication Date: 2024-02-23
    Description: Abstract
    Description: A line of 6 broadband seismometers have been deployed across a ridge in the Hualien County (Eastern Taiwan). From March 2015 to June 2016 the network has been continuously recording waves incoming from the Taiwanese regional seismicity. During that period, more than 2000 earthquakes with magnitudes Ml〉3 and distant from less than 200km were recorded. The hill is well approximated by a triangular topography of 3600m in length by 900m in height. Waveform data are open and available from the GEOFON data centre, under network code 5K.

    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.

    Dataset of the 6G seismic network at Los Humeros, 2017-2018 (2019)

    Details
    Publication Date: 2024-02-23
    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. Waveform data are available from the GEOFON data centre, under network code 6G and are embargoed until Jan 2023.

    Niphargus-Thiothrix associations may be widespread in sulphidic groundwater ecosystems: evidence from southeastern Romania. (2018)
    Details
    Publication Date: 2021-04-25
    Description: Niphargus is a speciose amphipod genus found in groundwater habitats across Europe. Three Niphargus species living in the sulphidic Frasassi caves in Italy harbour sulphur-oxidizing Thiothrix bacterial ectosymbionts. These three species are distantly related, implying that the ability to form ectosymbioses with Thiothrix may be common among Niphargus. Therefore, Niphargus-Thiothrix associations may also be found in sulphidic aquifers other than Frasassi. In this study, we examined this possibility by analysing niphargids of the genera Niphargus and Pontoniphargus collected from the partly sulphidic aquifers of the Southern Dobrogea region of Romania, which are accessible through springs, wells and Movile Cave. Molecular and morphological analyses revealed seven niphargid species in this region. Five of these species occurred occasionally or exclusively in sulphidic locations, whereas the remaining two were restricted to nonsulphidic areas. Thiothrix were detected by PCR on all seven Dobrogean niphargid species and observed using microscopy to be predominantly attached to their hosts' appendages. 16S rRNA gene sequences of the Thiothrix epibionts fell into two main clades, one of which (herein named T4) occurred solely on niphargids collected in sulphidic locations. The other Thiothrix clade was present on niphargids from both sulphidic and nonsulphidic areas and indistinguishable from the T3 ectosymbiont clade previously identified on Frasassi-dwelling Niphargus. Although niphargids from Frasassi and Southern Dobrogea are not closely related, the patterns of their association with Thiothrix are remarkably alike. The finding of similar Niphargus-Thiothrix associations in aquifers located 1200 km apart suggests that they may be widespread in European groundwater ecosystems.

    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.

    Study on feeding and spawning behavior of Otolithes rubber (Croaker Fish) in Sistan & Baluchestan (Chahbahar) coasts in 1995, Iran (2018)
    Details
    Publication Date: 2021-05-19
    Description: Otolithes ruber is one of the valuable commercial fishes in the South coasts of Iran and has been classified at the top level of commercial categorization, so owing to its economic importance, its biological characteristics were studied in Sistan & Baluchestan coasts in 1995. Three landing called Pozm, Bris and Remin were chosen for commercial catch sampling in this respect and 111 male fish and 149 female ones were autopsied within 7 months of evaluation. In feeding evaluation through numerical method, Squilla with 42.8% and Engraulidae with 1.4% consisted maximum and minimum percent of male fish stomach contents, respectively, and for female maximum and minimum percent of stomach contents were unidentified bony fishes with 35.7% and polynemidae family with 7%. The results showed that male fishes mature prior to females as they are smaller than females and no important difference was seen in sexual ratios in various month except March. Spawning was from December to the end of April and an outstanding spawning surge was observed from March to April. However, there was a light surge in November. The least coefficients of fatness in terms of male and female were 0.9 and 1 in April respectively and the most ones were 1.33 for male and 1.20 for female in January.

    Induced spawning in female Rainbow Trout Oncorhynchus mykiss by GnRH Analog (2018)
    Details
    Publication Date: 2021-05-19
    Description: GnRHa injection could accelerate and synchronous ovulation and spawning in female rainbow trout, the mean time to ovulation was reduced from 19.6±2.45 groups 2 to 5, respectively (P≤ 0.05). Also cumulative spawning rate increased in hormonal groups; up to 8th day after first injection. The cumulative spawning rate was 47.0, 34.4, 90.0 and 56.3% in groups 2 to 5 respectively. Although, until this time none the females in control group were spawned. In the end of experimental period (day 26), this rate was completed in group 2 to 5, but only 50% of females in control group was spawned. The mean weight of stripped eggs, egg diameter and mean survival rate to the eyed stage did not show any significant difference between experimental groups (P〉0.05). Testosterone levels were increased from 9.21±4.11 at time 0 to 23.47±14.29 ng/ml at 24 h after first injection, and then reduced to the basal levels in all hormonal groups (except group 5) at 72 h after first injection (10.91±3.11ng/ml) (P≤0.05). There wasn’t observed any testosterone levels fluctuation in control group.

    Investigation of heavy metals accumulation in muscle tissue of Mugil auratus in relation to standard length, weight, age and sex (2018)
    Details
    Publication Date: 2021-05-19
    Description: We assessed concentration of heavy metals (Zn, Cu, Pb, Cd) in the muscle tissue of Mugil auratus caught from important parts of Caspian Sea in Mazandaran Province in autumn 2002. After biometrical measurements, the muscle tissue of 32 randomly selected fish were separated using standard method MOOPAM 1999. Metals were extracted from the tissues using Closed Digestion method and acidic mixture (Moopam, 1983). Concentrations of the heavy metals were measured by FAAS (AAS4 Zeiss Gennany). Mean concentrations for Zn, Cu, Pb, Cd (14.327, 0.996, 2.337 and 0.321 ppm/dry weight) were compared with the international standards such as WHO, UK (MAFF), and NHMRC. A T. test showed higher than normal concentration of Pb, Cd in the muscle tissues. We found a positive linear relationship between accumulation of Zinc and Cadmium with weight, sex and standard length factors a negative linear relationship between accumulation of Pb with weight, sex and standard length. There was no significant relationship between accumulations of Cu with the biometrical factors of the sampled fish. Also, no relationship was found between sex and accumulation of Zn, Cu, Pb, Cd, while the accumulation of Pb in male samples were more than female ones.

    Description: During last 65 years the catch of mullets had increasing trends with some fluctuations in the Iranian coastal water of the Caspian Sea .In this period about 138 thousand tons of mullets have been caught. Mullet’s account for 35% of total catch annually .In recent years species composition of mullets has chanched in the Iranian coastal water of the Caspian Sea and catch composition of golden grey mullet increased from 76% in 1995 to 98% in 2006. In this survey some biological characteristics of golden grey mullet have been studied in Iranian coastal water of the Caspian Sea .Fish samples have been gathered from commercial catch of beach seine cooperatives monthly in Iranian coastal water of the Caspian Sea over 2006 and 2007. In the laboratory fishes have been measured biometrically and biological parameters have been calculated .Also catch statistics of mullets during 2006-2007 have been obtained and discussed. Results showed that the catch of mullets in beach seine cooperatives during 2006 and 2007 was 4181 and 3685 tons respectively that golden grey mullet contribute 99% and 98% of the catch composition of mullets respectively. Length range of golden grey mullet caught by beach seine cooperatives was 19-50.2 cm with mean length of 32.7 ± 6.4 (± SD) and weight range was 67-1475 gr with mean weight of 411 ± 255 gr. The age structure of this species was comprised 2-10 years old fish with mean age of 4.42 years old. In this survey totally the sex ratio of male:female of golden grey mullet was 356: 434 that was significant variation from equal sex ratio. Pick of the spawning in Guilan province was in October and in Mazandaran and Golestan provinces was in November. In October the proportion of spawning females declined from western area (Guilan province) towards eastern parts (Golestan province).The highest proportion of spawning females was in December in Golestan province. The highest GSI index value was observed in September and October and it was decreased in November and December and it was consistent during January till April. The mean absolute fecundity was 700881 ± 429987 eggs with minimum and maximum fecundity of 200112 and 2282862 eggs respectively. The Lm 50% for female golden grey mullet was calculated as 33.6 cm.

    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.

    Description: Research project was conducted on some biological aspects of lobster in Oman Sea in the years1385-86. During the project some parameters such as length distribution, spawning peak, length (Carapace) at first maturity, the length at which 50% of the lobsters were found to be mature sexually, sex ratio, relative frequency index and population dynamics parameters were examined. Quantitative factors and catch composition of lobster including the amount of catch in terms of weight and number of ovigerous-female, under-sized specimens and so were compared by monthly. According to the results of present study caught specimens were male with carapace length of 22 and 110 mm respectively. The smallest ovigerous female was taken as 46mm CL when length at first maturity was estimated to be 69-70mm. the male: female ratio was 0.7: 1.3 for the whole year. A closed fishing season for the species is proposed during spring and September and October in Oman Sea. A large amount of the catches for the all sampling months came from the under-sized specimens, consist of 50 to 85% of the total catch. Therefore, presence of these small length groups have direct effects on time of closing season. Population dynamics parameters were calculated as follows: K=0.57 year, L∞= 103mm and Ǿ = 8.69. Total mortality (Z), natural mortality (M) and fishing mortality (F) coefficients were calculated as 2.73, 0.87 and 1.86, respectively. Exploitation ratio for the whole population was 0.681, indicating an overexploitation of the species. Based on the available data, the recruitment pattern for lobster was obtained for two season including spring (major) and autumn (minor). Catch per unite effort (CPUE) was calculated as 0.908 kg/Cage/day which was higher in comparison with two other areas including Ramin and Chabahar. Examination of CPUE for a 10-year period showed a decreased trend and the reduction for the year 1386 was about 30% when compared to the data from the year 1375. Moreover, the mean length during 1369-70 to 1385-86 (present study) decreased for the three areas including Pozm, Ramin and Chabahar, so that the carapas length decreased up to 10 mm in length. This sudden decrease in mean length during the 10-year period should be considered as a serious precariousness for sustainable exploitation of lobster in Oman Sea along Sistan and Baluchistan province.

    Effects of endocrine disruption by 4-nonylphenol ethoxylate on the growth performance and immune response of female and male immature koi carp (Cyprinus carpio carpio) (2018)
    Details
    Publication Date: 2021-05-19
    Description: Nonylphenol (NP) is an endocrine disrupting chemical which has been shown to be able tomodulate endocrine system of various organisms by different mechanisms. The objective of this study was to investigate the potential effects of 4-NP and 17-β - estradiol (E2) on the immune parameters (IgM levels and lysozyme activity) of the teleost Koi carp (Cyprinus carpio carpio) for a better understanding of the immunereproductive system interactions. The experimental fishes were injected with ascending doses (10, 50,100 μgg^-1 body weight) of 4- nonylphenol (4-NP) and (2 μgg^-1 body mass) of 17-β-estradiol (E2) or vehicle during 3 weeks. After 21 days, the fishes (180) were anesthetizedand their blood samples were collected from caudal vein, then they were dissected and sexually separated by gonad characters. The measurement of immune parameters in plasma showed that 4-NP induced significant increase in the IgM levels and lysozyme activity at dose of 50 μgg^-1 while the levels of these parameters in the higher doses (100 μgg^-1 ) decreased compared with the control group (p〈0.05). In addition the treatment, with 2 μgg^-1 E2 significantly decreased both the IgM levels and lysozyme activity after 21 days of injection. These results indicated that 4-NP and E2 could lead to disturb the balance of immune system with potential consequences for immature koi carp.

    The innate immunity changes of the female anadromous hilsa shad, Tenualosa ilisha , during spawning and post spawning season (2018)
    Details
    Publication Date: 2021-05-19
    Description: Tenualosa ilisha (Hamilton) is a valuable migratory fish belonging to the family Clupeidae and it is distributed in a wide area from the Persian Gulf to coasts of Pakistan and China’s southern sea. The aim of the present study was to investigate the changes occurring in innate immunity parameters during upstream migration and comparing them to those during post spawning. Sixty mature female hilsa shad were obtained using gill net from Karoon River in Khorramshahr during the spawning period (July, August and September 2014) and Hendijan coasts along the Persian Gulf coasts during post spawning period (October, November and December 2014). Immediately, blood samples were collected from the peduncle vein and then parameters including WBC (White Blood Cell) count, Differential WBC Count, plasma lysozyme content and C3 and C4 complement activity were determined. Based on the results, the levels of WBC, lysozyme and C3 during the spawning period were lower than those recorded during post spawning period. However, C4 levels were higher during spawning (p〈0.01). This fact revealed that some innate immunity parameters experience depression during upstream migration and spawning, while these parameters increase during the post spawning period, indicating the suppressive effects of spawning on fish immunity.

    Description: Biological and reproduction characteristics of female big-eye kilka (Clupeonella grimmi) including body weight, fork length, age, gonad development stages, gonad weight, ganado somatic ratio (GSR) were studied. We sampled 808 fish specimens from the Southern Caspian Sea, Babolsar Area during December 2002 to May 2003. Gonad development stages were assessed through tissue sectioning. Results revealed spawning peak to occur in early January. We also measured body weight as 8.88±0.08 grams, fork length as 1.03±0.26 mm, age as 3.6±0.03 years, gonad development stage as 3.67±0.03, gonad weight as 0.5±0.01 grams and ganado somatic ratio (GSR) as 5.39 ±0.1 in the specimens. Totally, five age classes, dominated by the 4+ years were distinguished while no 1+ year's age class was observed. The abundance of gonad developmental stages 2 - 5 was 18.19%, 14.60%, 48.89% and 18.32% respectively. Macroscopic (visual) and microscopic (tissue section) observations of oocyte revealed the same results for gonad development.

    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.

    Determination of maturation and spawning season of Otolithes ruber (Croaker Fish) in Khuzestan coastal water, Iran (2018)
    Details
    Publication Date: 2021-05-19
    Description: In this study, the stage of gonadal development, type and season of spawning of Otolithes ruber in the North West of Persian Gulf were identified. O.ruber maturation and spawning were studied by macroscopic, microscopic, and histologic observation of gonads which obtained from October 1996 to September 1997 in Khouzestan coasts. In the histologic sections of gonad tissue, stages I to VII of gonadal development were distinguished. Post Spawning follicules were observed only in stages VI and VII (in April and May). Atretic ovums were also clearly observed in these stages. Frequency of Ovum diameter distribution in stages II to V is a unimodal which proves that annual maturation of ovums and spawning of this species are simultaneous. The highest level of GSI was observed in March and also higher stages 01' gonadal maturation were observed in March and April. Fast drop in GSI in May and within occurrence of both spawning and spent individuals in only two months of the year shows the relatively short spawning season is spring (April-May). Sexual maturation of females occured after the males and its first length in females was 216 mm.

    Biological survey on Penaeus indicus in the Jask area (Oman Sea) (2018)
    Details
    Publication Date: 2021-05-19
    Description: The indian white prawn (Penaeus indicus), as one of the commercially important and dominant species along the East coast of Hormozgan province, is a very potential and prospective candidate species for shrimp farming. Since, there wasn't well enough information about biology of this species from Iranian wateres, therefore. some biological aspects such as growth rate, reproduction behaviour distribution pattern and feeding habits were studied from March 1997 to March 1998. Monthly sampling were carried out from the fishing grounds and estuaries of Jask area in the Oman Sea by small trawlers and beach seines gears. Initial growth 01 male was faster than female, with calculated K=l.5 for male and K=1.3 for female. Isometric growth trend was observed in both sexes. Sexual maturity attained within the first 12 months. Spawners were occured abundantly during post-winter, spring and beginning of summer. Postlarvae and sub-adults were found in the esturies with 25-100 mm length, and high densities were observed around the mangrove's roots. They spend at least 3 to 5 months of their life span in the esturies. Analysis of stomach contents revealed that this species is an omnivore with indicative contents of detritus, polychaetes, crustaceane, bivalves, algae and sand particles, with preponderance of vegetable constituents in the sub-adults and of detritus in adults.

    Seminatural propagation and rearing of Roach (Rutilus rutilus caspicus) (2018)
    Details
    Publication Date: 2021-05-19
    Description: A research experiment was conducted to provide a protocol for seminatural propagation and rearing of Roach up to release size. The attempt was made to combat the declining trend in the population size and catch of the fish in the Caspian Sea. The optimum temperature for spawning brood-stocks lasts from middle March to late April when the ambient temperature range is 12-17 ֯C. During the four months research period, brood stocks were caught in the estuary of the Gorganrood in Golestan Province, north east Iran. The stocks were released into 2 hectare earthen ponds enriched with manure and fertilizers. Artificial spawning grounds made of pine branches were placed in the ponds. Ponds were stocked with 700 female breeders with an average weight of 150 grams and around 350 male breeders weighing 100 grams on average. Spawning and fertilization of eggs occurred in the ponds of which an estimated 80-90% eyed that were observed from the fifth day onwards. The starting of hatching was observed in the 6th day and yolk sac absorption was observed in day 4 to 6. The larvae were fed on natural zooplankton and artificial food. Assessment of 146 fries for ingested food indicated that the fries fed on Rotifer (Rotatoria sp. and Daphnia sp.) in the ponds. The length-weight relationship was not significantly different among the ponds and also specific growth rates (SGR) did not show any difference in the fries. The relative gut length in the fries were smaller than I (RLG〈1) and fries with an average weight of 0.5 to 1 gram were released into their natural habitat.

    The production of all-female in rainbow trout (Oncorhynchus mykiss) using indirect feminization (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The sex reversal technique in fish is widespread in many countries. The development of these techniques is desirable because rainbow trout males reach their gonad maturity earlier compared to the females. Rainbow trout alevins were treated with 17α-methyltestosterone incorporated in the diet (0.5. 1.5, 3, 6 and 10 mg/kg) for 60 days from the beginning of first feeding. Sex was determined at 180 and 680 dpf by sampling fish (n = 20) from each group and examining gross gonadal morphology under a dissecting microscope. Also sex reversal ratio and growth performance were determined in hormone-treated groups. These sex reversed functional males were reared for brood stock until they attained sexual maturity. At the end of experiment, normal rainbow trout eggs were fertilized with the sperms taken from sex reversed males for producing all-female populations. Examination of the results showed that 17α- methyltestosterone was effective in all treatment. The highest sex reversal ratio with 100% was observed in group treated with 0.5, 1.5 and 3 mg/kg 17α- methyltestosterone. The highest live weight ratios were observed in groups fed with 6, 0.5 17α-methyltestosterone and control group. Female progeny produced from the sex reversed males were 100 % in all males that sired offspring. All female trout stocks produced by this method have advantage in rainbow trout culture since the fish is not meant for direct human consumption and is used to generate brood stock, therefore, difference of growth parameters do not influence the success.

    Artificial Propagation of Tench (Tinca tinca) to Fingerling Size in 1994 (2018)
    Details
    Publication Date: 2021-05-19
    Description: The tench, predominantly lacustina fish, lives in stagnant or sluggish water-bodies with silt covered bottoms. The artificial propagation aimed to produce fish fries for re-stocking programme in natural ecosystems. The brooders comprised of 130 female and 80 male fish. The individuals weight of fishes ranged between 0.2 - 0.45 kg. The female and male fishes caught from wild stock, were separated and kept in two earthen ponds. The biotechnique of carp production were used for culture process. The eggs stripping conducted 8 times according to the ripeness of the brood stock. 60 femal spawners were injected by the Gonadotropic hormone from pituitary glands of carp fish to induce the brooders. The used dosage was between 3-8 mg per kg of body weight, applied in two doses. With only one treatment, 6-8 mg hormone were injected per kg of body weight. Water temprature were 20-24°C in June. Male spawners were treated only once with 3-4 mg of the hormone per kg of body weight. The experiment showed, in two application the effective dose of hormonewas 6-8 mg, that helped 80-100% of the female fishes to discharge eggs. With one treatment, the efficiency of hormone was 7-8 mg, which induced 80-85% of the female spawners to release eggs. The eggs were put in saline carbamid solution mixture after fertilization to eliminate stickness and then washed with pure water. The previous washing treatment took 45-75 minutes and the next one 25-45 minutes. The eggs fertilization rate were 70-85%. Incubation of eggs up to the hatching in Weise jar were 2-2.5 days. The survival rate of the hatched fries were 85-95%, and the size of newly hatched larvae were 4.5-5rnm. The larvae were placed into large Zuge glass. After 4-5 days the young fishes began to feed actively. The diameter of dry eggs were 0.52 - 4 mm and the swelled ones 0.8 - 0.65 mm. Number of eggs/spawners (working fecundity) were 10848 - 17710, and relative fecundity were between 80-350 eggs per 1 gram of body weight. Color of the eggs were bright yellow and greenish yellow.

    On Some Biological Aspects of Acipenser stellatus in the South West of the Caspian Sea in 1994 (2018)
    Details
    Publication Date: 2021-05-19
    Description: During the fishing season, the statistical study on biological observation was carried out in four fishing stations located in the south west of the Caspian sea. During the research activity 2806 stellate sturgeon were sampled. The resualt revealed that the ratio of stellate eggs weight used in processing of caviar were 20.7% of the total weight of the body. The number of females were more than males in the catch (77.8%) . In 1991 the average lenght of females was 134.1 cm and the average weight with internal organs was 11.86 kg. But the mean lenght and weight in 1993 were 120.5 cm and 11.6 kg. The average age for female and male were estimated 12 and 10 years old respectively. Among the samples 92.7% of females were in the fourth stage of maturity and 60.4% of males were in third stage of maturity. In spite of the fact that during 1984-1991 fishing effort for catching Acipenser had been increased, yielding caviar had been decreased. This state was continued until 1994. So it was revealed that increasing fishing efforts wasn't led to increase the exploitation of Acipenser stocks.

    Sex hormones changes in the reproductive cycle of female Trichiurus lepturus (2018)
    Details
    Publication Date: 2021-05-19
    Description: Ribbon fish, family Trichiuridae, is one the most important protein resources of the Indian Ocean. The considerable density of these aquatic animals, especially the dominant species Trichiurus lepturus, has drawn many researchers' attention to its biological characteristics and its reproductive characteristics in particular. The sampling was carried out in the Oman Sea from March 95 to November 96 (n=778). Studies on Estradiol - 17 - β, Progesterone and Cortisol hormones in female Trichiurus lepturus indicated that the production of these hormones increases considerably from maturity stage II. The serum levels of Estradiol - 17 - β hormone peaked during September, October and November and it remained high in the other months (1500 pg/ml). High levels of Progesterone occurred from December to March (during the spawning season). The changes in the Cortisol levels from August to December and again from February to March (0.5 - 3.5 mic/100 ml) were significant. The Estradiol - 17 - β fluctuation was observed simultaneously with the vitellogenesis process and absorption of Vitelline by the oocytes during their maturation. The changes in the oocytes membrane as well as the perforated channels impact on serum levels of Estradiol - 17 - β and Cortisol hormones have been discussed in this paper. The relative high levels of Estradiol - 17 - β during the whole year is probably related to the long spawning season of this species during autumn, winter and spring.

    Description: As part of the identification and distribution mapping of Clupeid fish in southern Caspian Sea, we studied abundance and species diversity of the fish in Mazandaran and Golestan Coastal waters during August-April 1999 to 2001. In the 336 specimens studied, four species were identified including Alosa braschnikowi. Alosa caspia, Alosa saposchnikowi and Alosa kessleri. The most abundant species was Alosa braschnikowii comprising 84.4% of the individuals and Alosa kessleri was the least abundant comprising 3.2% of the sample. We also traced an increasing trend in abundance of Alosa braschnikowii from east to west such that 43.8% of the fish found in Golestan Province waters and 56.2% in Mazandaran Province waters. The highest fork length and weight was recorded as 395 mm and 760.3 grams respectively for Alosa braschnikowi and the lowest was recorded for Alosa caspia with 110 mm and 109 grams respectively. In Alosa braschnikowi male were dominant and relative abundance of male and female in Mazandaran Province was 44.2% and 55.8% respectively. In Golestan, the relative male and female abundance of Alosa braschnikowi was 30.6% and 69.4% respectively. Female to male sex ratio in the A. braschnikowi was 1:1.26 and 1:2.26 respectively in Mazandaran and Golestan provinces. Overall female to male sex ratio was calculated as 1:1.6 for the species. The caught A. braschnikowi were in 1+ to 6+ age groups with the 2+ group comprising 28.9% and 1+ and 6+ comprising 8.9% of the sample.

    The reproduction biology of Barbus esocinus in Dez dam reservoir (2018)
    Details
    Publication Date: 2021-05-19
    Description: This study was carried out from April 1999 to March 2000 in Dez dam reservoir located at North Khouzestan province. From the total number of 607 specimen of collected fish, 267 and 64 were males and females respectively, and276 specimen were immature. Samples were caught by hooks and gill nets. Length range of females was 156-1350 mm and their weight range was 31.7-26500 g. Males ranged 183-1065mm in length and 48-12208g in weight. The males showed more ranges in length and weight comparing to females. The spawning period is very short and occuring in spring after flooding of the river and increase in the reservoir water level. This species is a total spawner and eggs are release in upstream regions and reservoir shallow waters on bottoms gravels. Spawning occurs in 24°C. Fecundity was intermediate. Sex ratio was 4.2:1.0 (male/female). Males show a faster maturation. According to the ratio of gut length to the body length, it seems to be an omnivorous species, but all samples were found to have fish in their stomachs (100%). Feeding intensity was higher in males. Annual growth is slow and asymptomatic length is more than 2m. Relative growth in weight is not in accordance with growth in length for various length groups, and relative growth in weight is increased with increasing of fish length. Growth of this species is positive allometric type. Various length groups were observed in examined specimens. It I seems that it has a longer reproductive life comparing to its pre-maturation life. Relative fatness is higher in females.

The study was conducted on 60 breeder Acipensers including 40 female and 20 male specimens. The fish were caught at stations in the vicinity of the SefidRud River in Guilan Province. Male spawners were treated using single injection method while females received dual injection (Bio-physiological control). Propylene glycol (PG) was administered after the muscular injection near the second dorsal scute to increase the viscosity of the solution during absorption. Depending on the stage of sexual maturity in the fish, GnRH at doses of 5, 10, 15, 20, 30 µg/kg BW was used in combination with a dose of I or 2 mg kg of domperidone. The position of G V was used as an index to determine sexual maturity in females while in males sexual maturity was determined on the basis of testis and sperm quality. The female fish showed GV in a range of 3.64 to 14.30. The results indicated that reduction of stress during catch, transportation, maintenance and handling and selection of breeders with suitable morphology will result in increased reproduction success. It was also found that male breeders given a dose of 20 and 30 µg/kg BW GnRH along with 1 and 2 mg kg of domperidone respectively were the most successful in spermiation. For female breeders, those received a dose of 10, 15 and 20 µg/kg BW GnRH along with 2 mg/kg of domperidone exhibited the most suitable conditions in ovulation. These females responded well to artificial breeding provided they possessed G V in the range of 3.64 to 14.30 depending on the water temperature until the germinal vesicle broke down (in vivo). Alleviating stress during capture, handling, transport and confinement, selecting breeders with suitable morphology and identifying correct stage of sexual maturity are the factors that help achieve higher production by substituting GnRH with a combination of GnRH and domperidone. Therefore, this compound is recommended as a suitable substitute for pituitary extract and other gonadotrophic analogues in the artificial breeding of Acipenser stellatus.

    An investigation on feeding habits of northern pike of Anzali Lagoon (2018)
    Details
    Publication Date: 2021-05-19
    Description: Northern pike (Esox lucius L.) as a major game fish can be valuable in the management of water resources. In the present study, a total of 152 pikes from four areas: Abkenar (24%), Sorkhankool (10%), Siakeshim (54%) and Sheyjan (12%) were sampled. Female fishes were 75.6% of the samples and males were only 24.4%. Northern pike showed relatively fast growth and fishes above two years of age were mature and reached an average length of 32 cm. Feeding intensity and growth co-efficient in this species were correlated. Growth was highest in the lower age groups and with an increase in age and size, the feeding intensity and growth co-efficient of this have decreased. Northern pike in different ages feeds on different species of fish found in Anzali Lagoon. The most important of these fish species are Carassius auratus, Hemiculter leucisculus, Rhodeus sericeus amarus and larvae of Chalcalburnus chalcoides. In the 0+ age group pike mainly feeds on zooplanktonic Mysids. The results of the present study showed that Northern Pike is not restricting populations of commercial fish species of Anzali lagoon, but on the contrary it plays an important role in biological control of reproduction and propagation of non-commercial species like C. auratus and H. leucisculus.

    An Investigation on Ecology of Mudskippers in Hormuzgan Coastal Areas (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The most important habitats of mudskippers are muddy areas in tidal zone of tropical mangrove forests. Mudskippers are related to Oxudercinae subfamily of Gobiid fishes. Three most distributed species of Hormozgan mudskippers were Periophthalmus waltoni, Boleophthalmus dussumieri and Scartelaos tenuis. These fishes can be considered as euryhaline and eurythermal aquatic species, because they can tolerate a wide range of salinity and temperature. A research was done since september 2008 to september 2009 in two important mangrove regions of Hormuzgan (Tyab and Khamir) to determine some ecological characteristics of inhabited mudskipper species. Results showed that nitrate levels are significantly different between tidal lines and seasons (P〈0.05). Maximum nitrite concentrations were recorded 53.2 and 92.5 µg/l in Khamir and Tyab respectively. The annual correlation matrix showed that a positive correlation between phosphate concentration and nitrite and silicate (P〈0.05). Silicate concentration was very high, because of too low density of diatoms and radiolarians. Some species of diatoms, dinoflagellates, cyanobacteria and larvae of crustacea and echinoderms were observed with different density and diversity. Sediment composition of the studied areas were categorized in three classes (clay, sand and clay - sand). Polychaetes formed dominant group of benthic fauna in Tyab and Khamir areas. High density of capitellid worms was possibly related to some environmntal stress caused by activity of fishing and cargo vessels. It was not observed significant difference between fishes length in two areas (P〈0.05); Mean lengths of P. waltoni, B. dussumieri and S. tenuis were calculated 9.85, 14.7 and 11.5 cm respectively. Spawning period of each three species in both areas were obtained from late winter to late spring based on gonadosomatic index values. Male to female sex ratio of P. waltoni, B. dussumieri and S. tenuis were calculated 1:0.45, 1:0.41and 1:0.74 respectively. Absolute fecundity of P. waltoni, B. dussumieri and S. tenuis were estimated 3558 ± 2202, 3952 ± 1030 and 6742 ± 1939 respectively. P. waltoni feeds mainly on fiddler crab, S. tenuis uses crustaceans and gastropods and B. dussumieri has a vegetarian diet.

    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Aquaculture for human consuming species is being considered as the first substitution of catching aquatic species due to increase of human population and decrease of wild aquatic stocks. In this study, the hybrid sturgeon Bester (female beluga x male sterlet ) was produced for the first time in Iran. Sperm of 1.35 kg male Acipenser ruthenus was used to fertilize the eggs of 125 kg female Huso huso in Shahid Marjani Sturgeon propagation center (Agh Ghala, Golestan province). The fries of bester and control treatment of beluga were transported to International Sturgeon Research Institute (Rasht) after about one month by reaching to 490 mg and 377 mg of weight respectively. All fishes fed by artificial concentrated food (48-50% protein and 15-17% fat) after a period of feeding with Artemia and Daphnia. Sorting was carried out according to increase of fish weight for both fishes. Results showed that the imported sterlet spawners were not at the high maturation stages and especially the males had not suitable sperm quality. It showed that up to 2 months of age , these was no significant difference between bester and beluga weight but from this age up to 2 months of age the weight of beluga was greater. Meanwhile from 2 months old up to the end of the study (21 months) the weight of bester sample was significantly greater than beluga. The comparison of FCR for the whole rearing period showed no difference between bester and beluga (2.4 and 2.3 respectively). In general, the increase and decrease pattern of GR and SGR were coincided to each other, but showed monthly differences. Growth rate (GR) and specific growth rate (SGR) of bester were greater than beluga from 4th and 3rd month of rearing period respectively.

    Study of Possibility of Reproduction and Mass Culture of Nereis diversicolor (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The present study was firstly conducted to study the rate of sexual maturity in Nereis diversicolor under suitable conditions of temperature and photoperiod. The second objective was to determine the potential of artificial breeding in these worms for mass culture. Nereis diversicolor worms were collected from the Anzali lagoon in 4000 sampling operations during the years 2004 to 2006 using Ekman grab with a surface area of 400 cm2. The water salinity, temperature and total organic matter (TOM) of sediments in the sampling region was recorded. The worms were maintained in 0.5 tons (1 x 1 m2) tanks containing clayey-muddy sediment to a height of 20 cm covered with 10 cm water (5 ‰) until they reached a weight of 200-300 mg. Sexual maturity in this species was attained at 4-6 ºC and spawning occurred at approximately 16 ºC. The first gametes were observed five weeks after the temperature increased from 6 to 16 ºC. Sexual maturity was studied at various salinities (0.5, 5, 12, and 15 ‰). Results indicate that these worms attained earlier sexual maturity at salinity of 15 ‰, compared to other salinities studied. No significant differences (P〉0.05) were observed between sexual maturity attained at 12 ‰ and 15 ‰. Stocking density (20, 50, 100, 150 worms) was studied in terms of sex and showed that number of females were higher than males and the ratio was 11:1 (female:male). No significant differences (P〉0.05) were observed between the various stocking densities and their replicates. The effect of light and photoperiod in synchronizing reproduction in male and female N. diversicolor was studied. It was evident that reproduction behavior in adult worms increased for a period of one week at the end of each month after they are exposed to a prolonged photoperiod (L:D=16:8) followed by a period of dim light (simulated using 1 W lamps). Feeding trials were carried out with Saccharomyces cerevisiae, formulated fish diets and humus. Results showed that this diet was effective in speeding up sexual maturity in worms and significant effect of treatment was observed (P〈0.05) in worms fed a diet of humus alone. Eggs and sperms were fertilized and worms developed from the young monotrochophore with jelly layer to the trochophore larvae.

    A biological investigation into anchovy kilka (Clupeonella engrauliformis) in Anzali fishing ground, in 1993 (2018)
    Details
    Publication Date: 2021-05-19
    Description: In the recent years the Kilka fishing in Iranian coastal waters boosted rapidly. The rich stock of Kilka has provided the possibility of apt exploitation. Among the three Kilka species, dwelling in the Caspian Sea, 90% of Iran's catch consists of Clupeonella engrauliformis. Analyses of Data show that the sex ratio varies widely with the change of season. In autumn the spawning reaches to the peak and the female population declines in catching. The oil fat content and intensity of feeding in both sexes did not reveal significant differences. Average size range is 194.91mm in summer und 97.97mm in winter. Length frequency in both sexes varies from 100 to 110mm, but the female size range changes are wider. Mean weight of Anchovy Kilka is 7.84g in spring and 5.92g in winter. The research also shows that in winter large size Kilka are distributed at the deepest area of the sea. Therefore, it is suggested that to catch the Kilka, fishing operation should be done at deeper depth.

    An investigation on artificial reproduction of Mugil cephalus (2018)
    Details
    Publication Date: 2021-05-19
    Description: Cultured nine years old breeder M. cephalus specimens were subjected to eight artificial breeding treatments from December till February 2003. In treatments 1-5, breeders received two injections of CPH and LHRH-A2 coupled with Domperidone or a mixture of CPH and HCG in an interval of 24 hours. Female breeders in treatments 6-8 received a gradual daily injection of 500 IU HCG per kilogram of body weight for 5 days. Male breeders in treatments 6-8 were given 5-10mg of MT-α-17 in addition to HCG and then subjected to two injections similar to that of treatments 1-5. Results showed that male breeders in stages +2 and +3 of all treatments that had received HCG produced more milt than those injected with MT-α-17, such that each male was used 2-6 times for milting purposes. Of 27 female breeders, 22 spawned 1-2.6 million eggs among which eight females' eggs were fertilized 10-95%. Hatching rate was between 0.008 to 88.9% and a maximum of 2 million larvae were produced. The best time for artificial breeding is December when mean egg width is ≥600 microns. Statistical analysis of egg width, hatching rate and larvae production showed a significant difference between treatments 1-5 and 6-8 (p〈0.05). This proved the supremacy of multiple injections including HCG for artificial breeding of Mugil cephalus.

The present research was carried out in order to conduct a qualitative evaluation of the growth and development of the reproductive system of three sturgeon species (Acipenser persicus, Acipenser gueldenstaedti, and Huso huso). In this evaluation two histological approaches, gonadectomy and biopsy, were employed. The studied sturgeons consisted of 58 one, two and six years old reared juveniles. Some 60% of the one-year-old Huso huso were of unknown sex, 20% were previtellogic females and 20% of the males were in the early stage of spermatogenesis. On the other hand 50% of the one-year-old Acipenser persicus were also of unknown sex, 30% premature females and 20% premature males. Some 30% of two-year-old Huso huso were of unknown sex, 40% premature females and 10% of the females were in stage I of sexual maturity and 10% were premature males. Among the six-year-old specimens, 60% of the Acipenser persicus were females in stage II of sexual maturity, 20% were males between stage II and III of sexual maturity and 20% were of unknown sex, while in the same age group 50% ofAcipenser gueldenstaedti were males in stage II of sexual maturity and 50% were females in stage II(semi lipid) of sexual maturity. The results of the study indicated that 28.75% were females were in stage II of the sexual maturity, 14.28% were female in stage II (lipid) of sexual maturity, 14.28% females in stage I of sexual maturity, 28.75% males between stage II and III of sexual maturity and 14.28% were males in stage IV of sexual maturity. The conducted study on the juvenile sturgeon confirmed that the growth process of the gonads occurred as it would have happened under natural circumstances. Occurrence of six-year-old Huso huso in stage IV of sexual maturity indicated that the rearing conditions in the fiberglass tanks and earthen ponds have been favorable and on the other hand no extra surplus energy has been used.

    In Vivo oocyte maturation and ovulation in females and spermiation in males of hybrid sturgeon, bester (2018)
    Details
    Publication Date: 2021-05-19
    Description: Bester, a hybrid sturgeon (Huso huso L. females ´ Acipenser ruthenus L. males), neither spermiate nor ovulate in the captivity. Thirteen-year-old adult male and female bester were injected with LH-RHa (0.1-0.3 mg/kg B.W.) intramuscularly and spawning status of the treated fish was checked 24-48 hours later. Additionally, changes in serum levels of DHP in both the responded and the non-responded individuals were monitored 0, 1, 3, 6, 9, 12, 24, 48 and 72 hours after treatment. Between 70-100 percent of the LR-RHa injected males individuals, and 11-40 percent of the females spawned 24-48 hours after the treatment; the rest did not respond to the injection. In the responded males, 3-9 hours after the treatment, serum levels of DHP increased; while in the females it occurred first after 12-24 hours. In contrast, during the same period, serum levels of DHP remained low in all non-responded individuals. The present study indicated that using 0.1-1.3 mg/kg B. W. of LH-RHa can induce oocyte maturation and ovulation in the females and spermiation in the males cultured bester. The results suggested additionally DHP as an appropriated steroid that could be used in the final maturation stage of the gonads.

    Description: The pharaoh cuttlefish (Sepia pharaonis) is the most aboundant species in the Persian Gulf and Oman Sea. The stock patterns of this species were studied concerning biological and morphological aspects. In addition to measuring the biological patterns, 20 quantitative factors were measured. The results of LSD test showed that tentacle organ is indicative factor which shows significant difference between male and female specimen of Bushehr and Balouchestan regions. Regarding to length and weight frequencies data the results indicated that males are always bigger than females and also, the cuttlefishes of the Gulf of Oman are bigger than Persian Gulf samples. The results of cluster analysis for both sexes showed that the cuttlefishes of both studied region belong to separate stocks. Taking into consideration the findings of present study including: (1) difference in spawning season, (2) results of dendrograms, (3) observed significant differences in one-way analysis of variance (ANOVA) for morphometric measurements, (4) differences in body length and weight, (5) as well as ecological variations of the Persian Gulf and "the pharaoh cuttlefishes of Bushehr and Oman Sea, have indicated that Balouchestan belong to two separate stocks.

    Description: We construct a new seismic model for central and West Antarctica by jointly inverting Rayleigh wave phase and group velocities along with P wave receiver functions. Ambient noise tomography exploiting data from more than 200 seismic stations deployed over the past 18 years is used to construct Rayleigh wave phase and group velocity dispersion maps. Comparison between the ambient noise phase velocity maps with those constructed using teleseismic earthquakes confirms the accuracy of both results. These maps, together with P receiver function waveforms, are used to construct a new 3‐D shear velocity (Vs) model for the crust and uppermost mantle using a Bayesian Monte Carlo algorithm. The new 3‐D seismic model shows the dichotomy of the tectonically active West Antarctica (WANT) and the stable and ancient East Antarctica (EANT). In WANT, the model exhibits a slow uppermost mantle along the Transantarctic Mountains (TAMs) front, interpreted as the thermal effect from Cenozoic rifting. Beneath the southern TAMs, the slow uppermost mantle extends horizontally beneath the traditionally recognized EANT, hypothesized to be associated with lithospheric delamination. Thin crust and lithosphere observed along the Amundsen Sea coast and extending into the interior suggest involvement of these areas in Cenozoic rifting. EANT, with its relatively thick and cold crust and lithosphere marked by high Vs, displays a slower Vs anomaly beneath the Gamburtsev Subglacial Mountains in the uppermost mantle, which we hypothesize may be the signature of a compositionally anomalous body, perhaps remnant from a continental collision.

    Artificial Propagation and Culture of Rutilus frisii kutum of Autumn Form for Restocking (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The Kutum, Rutilus frisii kutum, is one of the most important bony fishes in Iranian coastal of Caspian Sea. Its harvest range is between 9000-10000 tons in a year, nearly 60% of the income of Bony fish fishery produced by kutum fishery. The stock of this species reduced drastically in 1982 and the catch slumped to the less than 250 tons in a year. Kutum spawning grounds deterioration, illegal catch, lack of restocking program were the main cause of the decline. This Spices in nature comprised by two distinct form, autumn and spring form. It is worth to be mentioned, by the effect of Caspian Sea Bony fishes Research Center s experts in 1983, artificial spawning and releasing the fries to the sea were commenced and the catch steadily improved. But all activities concerning restocking of kutum concentrated in spring form, as at present about 260 million its fries are released into sea for restocking by Iranian Fisheries Organization, but for above reasons and lack of restocking program, the populations of autumn form gravely shrinked and neared to be extinct. Therefore, to enhance the biodiversity and boost fishers livelihood of kutum in Caspian Sea this project implemented by cooperation of Iranian Fisheries Organization (IFRO) and Caspian Environment Program (CEP) in Aquaculture Institute (Inland Waters). In this project, brooders caught from Anzali lagoon and maintained in two different condition, include of floating cages in Anzali lagoon and earthen ponds in Sefidrud Fisheries Research Station. The results showed that there weren t significant differences between two maintenance statuses in maturation period and other reproductive characteristics of brooders. The ratio of male to female was 1 to 1.4. Minimum and maximum weight measured 1450 to 3100 g (with average of 1850 g) in female and 670 to 1900 g (with average of 1165 g) in male, respectively. The first natural spawning of brooders occurred in the end of January in temperature of 8 till 10 °C in concrete ponds. Also, some of maintained brooders in earthen ponds spawned in February. The average number of absolute, function and relative fecundity determined 88565 16809, 73805 14008 and 48670 12056, respectively. For artificial spawning, male and female brooders injected by pituitary gland with dose of 2-3 and 4-5 mg/kg body weight, respectively. Approximately, 10 and 8 present of female were over-ripe and immature in March (artificial spawning time), respectively. More than 59 % of injected female brooders induced to spawning in first stage after 10-12 hours and 13 % of them in twice stage and 7-8 hours after first stage. And also, 27.6% of females didn’t positive response to injection. Dry method used for eggs fecundity and incubation period lasted 7- 10 days in 14-16 °C. In totally, eggs fertilization were more than 95% and the average of eggs fertilization percent in throughout of period measured more than 92.7 6 %. Eyed eggs appearance occurred 3 days after fecundity and its mean was 92.7 15.1%. Larvae after yolk sac absorption feed with dry milk for 4-5 days and then introduced into fertilized earthen ponds (500 m2 and equipped to aerators) in intensive condition and fed with micro pellet food for 3-4 month. In finally, more than 1.8 millions fries of 1-2 g and some more than 5 g produced and released into Anzali lagoon to its restocking for first time. It is expected that continuing of restocking process of autumn form kutum by Iranian Fisheries Organization eventuate to population increasing of this form in Caspian Sea in future.

    Publication Date: 2021-05-19
    Description: Due to the usefulness of shrimp broodstock pelleted diets, from aspects of, easier maintenance, transportation, broodstock feeding, and cheaper as compared to natural wet diets, the use of natural wet foods, include sand worm (Perinereis nuntica), cattle fish )Sepia pharaonis) and veal livier decreased and the quantity of pelleted diet increased. Survey was conducted, in tankes with a volume of 300 liters. Tanks were filled with 150 liters of water. 10 broodstock in each tank was left, with an average weight of 37±2 grams. Daily feeding rate, was twenty-five percent of their biomass. The survey was include, 9 treatments with 3 replicates in each tank as described below. Control treatment: broodstock feeding only with, sand worm (33%), cattle fish (34%) and bull livier (33%). Exprimental treatment 1: broodstock feeding with pelleted diet contain 50 percent crude protein and 8 percent crude fat (50%)+sand worm (16 %)+cattle fish (18%)+veal livier (16%). Treatment 2: broodstock feeding with pelleted diet contain 50 percent crude protein and 10 percent crude fat (50 %)+sand worm (16 %)+cattle fish (18%) and veal livier (16%). Treatment 3: broodstock feeding with pelleted diet contain 40 percent crude protein and 10 percent crude fat (50%)+sand worm (16 %)+cattle fish (18 %) and veal livier (16 %). Treatment 4: broodstock feeding with pelleted diet contain 40 percent crude protein and 8 percent crude fat (50 %)+sand worm (16 %)+cattle fish (18 %) and veal livier (16 %). Treatment 5: broodstock feeding with pelleted diet contain 50 percent crude protein and 10 percent crude fat (100 %). Treatment 6: broodstock feeding with pelleted diet contain 50 percent crude protein and 8 percent crude fat (100 %). Treatment 7: broodstock feeding with pelleted diet contain 40 percent crude protein and 10 percent crude fat (100 %). Treatment 8: broodstock feeding with pelleted diet contain 40 percent crude protein and 8 percent crude fat (100%). The results showed that, Gonadosomatic index (GSI) in treatments 3: control and 6, was significantly more than others treatments (p〈0.05). Hepatosomatic indexes, in often treatments was almost equal, and in some cases were significantly different (p〈0.05). In treatments 3 and control, absolute fequndity, was significantly more than others treatment (p〈0.05). The survival percent, in treatment 8 was significantly less than others treatments (p〈0.05). The survival percent in others treatments was not significantly difference (p〉0.05). From the aspect of mean weight of broodstock, wasn’t significant difference in treatments (p〉0.05). From the aspect of mean length of carapac, wasn’t significant difference in treatments (p〉0.05). From the aspect of mean body length, wasn’t significant difference in often treatments (p〉0.05), and in treatments 5 and 6 was significantly less than others (p〈0.05). In the determination of relasheship between kind of treatments and abundance of maturated broodsock, wasn’t significantly difference (p〉0.05). In the determination of, correlation between weight (g) and total length(cm), (r=0.71), weight and carapace length (cm) (r=0.70), the correlation was strong. Between GSI, HIS, carapace length and total length the correlation was intermediate (r=0.54). The correlation between absolutely fecundity and total length (r=0.20), absolutely fecundity and carapace length (r=0.28), absolutely fecundity and weight (r=0.35) was weak. The results showed that, the use of combination of pelleted diet and natural wet diets can increase female maturation indexes. Totally we can noted that, GSI, HIS and absolute fecundity of broodstock, that fed with pelleted diet contain 40 percent crude protein and 10 percent crude fat (50 %)+sand worm (16 %)+cattle fish (18 %) and veal livier (16 %) (treatment 3) was better than the other treatments. Positive effects of this treatnent on sexual indexes, was due to provide part of nutritional requirement of shrimp broodstock from pelleted diet.

    The possibility of sex identification in beluga (Huso huso) by using PCR-RAPD technique (2018)
    Details
    Publication Date: 2021-05-19
    Description: The goal of this study was to find a sex-specific DNA sequences in the male and female genomes of beluga (Huso huso), by random amplified polymorphic DNA (RAPD) assays performed on pooled DNA samples. Of the 310 different primers was tested, 7 primers produced no band. The most likely possibility is that PCR conditions have not been suitable for these 7 primers. It is also possible that these RAPD primers did not find suitable binding position to generate fragments. A single band was produced by primer 295 (OPT -17) which was specific to the male DNA. Further analysis of individual male and female beluga demonstrated that this primer yeilded a product that were in fact variable and reproducible, but were the result of variation in some individual males and females and not male-specific. Therefore, of the 4146 RAPDs scored, none were tightly linked to a sex-determining gene. The results support the idea that sex chromosomes are either not present or they weakly differentiated in the genome of beluga.

    Artificial spawning of Esox lucius (Pike), culturing fingerling size fish, providing Bio-normative (2018)
    Details
    Publication Date: 2021-05-19
    Description: The research project was implemented to obtain bio-normative of artificial spawning of Esox lucius and rear fries until fingerling size in earthen ponds. The artificial spawning occured in 4 stages, totally 96 brooders (32 females and 64 males) were used for the experiments. The pituitary gland hormone of common carp was injected at 4-7 mg per kg of body weight in each dose to the spawner females. The water temperature during spawning was 8-150C and the time of artificial spawning started from 4 of February to 20 of March. The maximum weight of brooder was 4 kg and the minimum 0.75 kg; the oldest female fish brooder was 6 years old and the male 5 years; the minimum age for both sexes was three years. The spawning took place both by natural state in earthen ponds and also by eggs extraction and fertilization. The quantity of eggs extracted from female spawner composed between 10-20 percent of the body weight. There was no significant differences between one and two step hormone injections. The injected female brooder was ready for artificial spawning 48-74 hours later. Mean incubation period lasted 120 degree days and yolk sac absorption lasted 160-180 degree days. The eggs stickiness was rather high and the rate of fertilization fluctuated between 45-85%. One gram dry eggs contain 90-150 ovum with 1.5-2 mm diameter, and swelled eggs were 70-85 pieces with 2.5-3.5 mm diameter. Absolute, relative and working fecundity calculated 22400-112000, 19760-36920and 5200-67400 eggs respectively. Larvae feeding, after yolk sac absorption, was performed with a solution of dry milk and soya bean juice. The feeding first was conducted with soya bean juice and Artemia nauplius in earthen ponds. After wards the natural productions of the pond, having been enriched with chicken manure, were used. The survival rate, from larvae to fingerling size, was 20-22% during 50 days culture period. During this time the fly grew to 7.4 gr with 8.5 cm length, in average.

    Reproduction biology of Penaeus merguiensis (Banana Prawn) emphesis of Fecundity in coastal waters of Hormozgan Province, Iran (2018)
    Details
    Publication Date: 2021-05-19
    Description: Penaeus merguiensis is the dominant species in coastal waters of Hormozgan province and approximately constitute 70% of the annual catch composition. Sex rate is analysis in natural population shows that the proportion of males to females is 1:1 and generally this proportion in carapace length is 28.6 and 25.7 mm more than other classes, which its peak is observed in 25.7 mm length class. Also proportion of males to females in May to December and April to May is more than other times which its peak is in December. The analysis of sexual maturation based on carapace length shows that LM50 for females of this species has followed the exponential equation and is equal to 32.8 mm (r2 = 90%). Minimum and maximum of absolute fecundity of this species with 20.7-31.5 mm C.L. are and 11300 and 14400 eggs respectively. This analysis of relative fecundity of this type showed that the relationship between carapace length and number of eggs was a type of poweral equation (F= 0.1208 C.L 3.8, r2 = 97%), however this relationship between total length (T.L) and wet weight (W) was F = 0.0002 T.L 7.1 (r 2= 0.68) and F= 0.1942 W 4.02 (r2=0.58), respectively, which showed the fecundity has 0.1942 W (r more correlation with the carapace length.

    Inheritance of RAPD marker in female grass carp (Ctenopharyngodon idella), male bighead carp (Hypophthalmichthys nobilis) and their F1 hybrids (2018)
    Details
    Publication Date: 2021-05-19
    Description: Genetic variation and inheritance of randomly amplified polymorphic DNA (RAPD) markers in female grass carp (Ctenopharyngodon idella) and male bighead carp (Hypophthalmichthys nobilis) and their F1 offspring hybrid have been studied. For this purpose, genomic DNA was extracted from muscle tissue according to phenol-chloroform method, and six decamer primers were used for amplifying polymorphic DNA. Results from 77 produced bands showed that all RAPD bands pattern of parents were present in F1 offspring hybrid, which indicated the high influence and dominance of the mentioned markers. The low difference in polymorphisms in used markers between F1 offspring hybrid and parents shows that parents are heterozygous in some loci, which can cause low difference in hybrids of two distinct genera. Although our results revealed that RAPD markers had a suitable efficiency in distinguishing parents from F1 hybrids, genetic diversity of triploid and diploid F1 hybrid were not detected by introduced primers.

    The amino acid compositions of muscle from wild and cultured of male and female Acanthopagrus latus (2018)
    Details
    Publication Date: 2021-05-19
    Description: The crude protein content and amino acid compositions of muscle from wild and cultured of male and female Acanthopagrus latus were determined by HPLC. There were quantitative differences between individual amino acids in the tissues investigated, depending on the sex and location. It was noted that, among all the samples studied in tissues, sexes and locations, lysine and isoleucine were the principal essential amino acid (EAA) and glutamic acid was mainly for non-essential amino acid (NEAA). Lysine and isoleucine of male muscles had a significantly higher (P〈0.05) amount than female muscles. The crude protein content in male and female muscles was not found to be significantly different. Depending on location, the percentages of arginine, leucine, isoleucine, lysine, serine, glycine, alanine and tyrosine were significantly different (P〈0.05) in muscles of wild and cultured fish. The wild seabream possessed considerably higher protein content than cultured seabream muscle. The results showed that wild male fish muscle contained a higher (P〉0.05) level of EAA than other groups. The results indicate that the Acanthopagrus latus is a healthful component of the human diet.

    Histologic study of ovarian changes during the reproductive cycle of female Yellowfin Seabream, Acanthopagrus latus (2018)
    Details
    Publication Date: 2021-05-19
    Description: This study was done to investigate the macroscopic and microscopic structure of the ovary of Acanthopagrus latus and their changes during sexual maturation cycle from October 2011 to may 2011. 80 A. latus from Mussa Greek (North West of Persian Gulf) were captured and transferred to the laboratory. After biometry, gonads were removed, were weighted and fixed in Bouin's Fluid. Samples were dehydrated, clarified, embedded and sections were prepared. After staining with H&E these slides were studied under light microscopy. Gonadosomatic indices, macroscopic and microscopic changes in the ovary during different months were recorded. The minimum value of GSI were measured in May, (0.31 ± 0.01) while its maximum was seen in March (9.9 ± 3.1). Cyclic changes in ovarian maturity were divided into six stages, including immature, premature, mature, ripe, spawning and resting. A. latus had asynchronous spawning that was occurred from February up to March.

    The effect of repeated implantation of Triiodothyronine on the performance of physiology of cultured female great sturgeon (Huso huso) (2018)
    Details
    Publication Date: 2021-05-19
    Description: The objective of this study was to examine the effects of triiodothyronine (T_3) implantation on the performance of physiology of cultured great sturgeon (Huso huso). Three treatments with 5 fish for each treatment were considered. The experimental treatments included: control (capsules containing cocoa butter alone), low level of T_3 (T_1; 1 mg T_3/kg body weight + cocoa butter), and high level of T_3 (T_10; 10 mg T_3/kg body weight+ cocoa butter). The capsules containing hormones and cocoa butter were intraperitoneally implanted to 3-year-old pre-vitellogenic stage female fish (mean initial body weight 6999.7±100.9 g) every 6 weeks over a six month period from January 2009 to June 2010. The serum levels of some hormone (T_3, cortisol, ACTH) and biochemical parameters (glucose, cholesterol and calcium) were determined at the initial time and three weeks after each implantation. Growth indices (WG, SGR and CF) were determined at the end of the experiment. The results showed that fish treated with the high and low T_3 doses produced significant changes in thyroid hormone levels (P〈0.05). Serum cortisol was significantly higher in T_3- implanted fish than in control fish (P〈0.05). Serum glucose and calcium concentrations were significantly greater in fish treated with the high T_3 doses compared to the other two experimental groups (P〈0.05). Significant differences were observed in serum ACTH and cholesterol concentrations among treatments in the last and second sampling time, respectively (P〈0.05). Final weight was the highest in T_1-implanted fish; intermediate in those implanted the high T_3 dose, and lowest in controls (P〈0.05). These results indicated that the long-term implantations of T_3 hormone influence the physiological parameters of great sturgeon and promote the somatic growth in a physiological dose.

    Some biological survey of the Clupeonella engrauliformis (Anchovy-like Kilka) in Guilan coastal region, the south-west of Caspian Sea, in 1996-97 (2018)
    Details
    Publication Date: 2021-05-19
    Description: According to a survey in 1996, among three species of kilka, living in the South-West of Caspian Sea, anchovy-like kilka composes 90.3% of total kilka catch. In all seasons of a year, anchovy-like kilka, in the second stage of gonadal maturation, shows higher abundance in the catch, compared with other maturation stages. This indicates anchovy-like kilka shows more positive phototaxis, at the beginning of its sexual maturation. Sex ratio shows females dominancy is 54.8-60, 7-75.9 and 82 percent in spring, summer, autumn and winter respectively. The average length of this fish in the four seasons with above order were 98.6±10.8, 97.7±10.3, 99.6±10.6, 100.1 ± 10.6 and the mean weight were 8.24±1.1, 7.5±1.7, 7.3±1.96 and 6.9±1.56 gr. The age composition of anchovy caught on spring in 1997 ranged between 2-5 years old and the dominate group was 3-year-old. The K value and infinite length calculated 0.27 and 147.8 mm respectively. No significant differences were observed between male and female concerning fat reserve and feeding intensity.

    An investigation on food habits and spawning season of Acanthopagrus latus (Sparidae) in the Persian Gulf (2018)
    Details
    Publication Date: 2021-05-19
    Description: Food habits and spawning season of Acanthopagrus latus (Sparidae) were studied in Bushehr, Delvar and Rostami waters of the Persian Gulf. Samples have been collected from March 1996 to February 1997 on a monthly basis. A total of 87 males and 95 females were examined and different biological parameters were measured. The Relative Length of the Gut (RLG) was estimated to be 0.64, which indicates that this is a carnivorous species. Food items have also been identified using numerical method. Out of 159 stomachs studied 36.36% were found to contain crabs, 33.99% other fish and 13.43% shrimps. The content of snails and sea urchins were 11/46% and 4/ 76% respectively. It is evident from the results of the study that A. latus feeds mainly on crabs and fish. The vacuity index was calculated to be 0.13. This indicated that this fish is an active predator. The Gonado Somatic Index (GSI) was estimated to be highest during February - March and lowest in June. GSI maxima was coincided with fecundity peak. The relationship between (GSI) and fish weight for females and males were r2=0.0235 and r2 =0.0214 respectively.

    Details
    Publication Date: 2022-05-26
    Description: This project was initiated to accomplish the necessary research and documentation of existing seismic techniques and systems for the study of sediments and sedimentary structures in the oceans. In this respect , it is an 'inventory' of methods and techniques for looking at small-scale features or changes in structures lying from 10 to 1000 m beneath the sea floor. It attempts to assess the vertical and lateral resolution capabilities of existing and technically feasible seismic systems. Some of the questions posed are: how closely can we determine vertical variation such as sediment layer thickness and vertical variation with depth; also lateral coherence or its disruption by such agents as facies changes, thinning or thickening, slumping, faulting; the nature of the basement structure, its areal coherence, velocity structure and associated anomalies?

    Microearthquake activity on the Orozco Fracture Zone : preliminary results from Project ROSE (2018)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-26
    Description: Also published as: Journal of Geophysical Research 86 (1981): 3783- 3790
    Description: We present preliminary hypocenter determinations for 52 earthquakes recorded by a large multiinstitutional network of ocean bottom seismometers and ocean bottom hydrophones in the Orozco Fracture Zone in the eastern Pacific during late February to mid-March 1979. The network was deployed as pan of the Rivera Ocean Seismic Experiment, also known as Project ROSE. The Orozco Fracture Zone is physiographically complex, and the pattern of microeanhquake hypocenters at least partly reflects this complexity. All of the well-located epicenters lie within the active transform fault segment of the fracture zone. About lialf of the recorded earthquakes were aligned along a narrow trough that extends eastward from the northern rise crest intersection in the approximate direction of the Cocos-Pacific relative plate motion; these events appear to be characterized by strike-slip faulting. The second major group of activity occurred in the central portion of the transform fault; the microearthquakes in this group do not display a preferred alignment parallel to the direction of spreading, and several are not obviously associated with distinct topographic features. Hypocentral depth was well resolved for many of the earthquakes reported here. Nominal depths range from 0 to 17 km below the seafloor.

    Publication Date: 2022-05-26
    Description: Also published as: Journal of Geophysical Research 84 (1979): 5487-5496
    Description: This geophysical survey of an approximate 1° square covers Mesozoic magnetic anomalies M0, M2, and M4 south of Bermuda. Bathymetry, magnetics, seismic reflection profiling, and seismic refraction data are presented. The isochron trend within the survey area at magnetic anomaly M4 time is 025°. Two left lateral fracture zones exist: the southern fracture zone has an offset of 〈10 km at M4 time and 33 km at M0 time. The northern fracture zone has an offset of 37 km at M4 time and 26 km at M0 time. These changes in offset are accounted for by asymmetric spreading, an 11° change in trend of anomaly M0 relative to M4, and by M0 time, growth of a small right lateral fracture zone. Seismic refraction data provide poor control on the shallow crustal structure but suggest the presence of significant lateral inhomogeneities within layer 2.

    Description: The 2006 Mw 7.8 Java earthquake was a tsunami earthquake, exhibiting frequency-dependent seismic radiation along strike. High-frequency global back-projection results suggest two distinct rupture stages. The first stage lasted ~65 s with a rupture speed of ~1.2 km/s, while the second stage lasted from ~65 to 150 s with a rupture speed of ~2.7 km/s. High-frequency radiators resolved with back-projection during the second stage spatially correlate with splay fault traces mapped from residual free-air gravity anomalies. These splay faults also colocate with a major tsunami source associated with the earthquake inferred from tsunami first-crest back-propagation simulation. These correlations suggest that the splay faults may have been reactivated during the Java earthquake, as has been proposed for other tsunamigenic earthquakes, such as the 1944 Mw 8.1 Tonankai earthquake in the Nankai Trough.

    PARTOS - Passive and Active Ray TOmography Software: description and preliminary analysis using TOMO-ETNA experiment’s dataset. (2017)
    Details
    Publication Date: 2020-02-24
    Description: In this manuscript we present the new friendly seismic tomography software based on joint inversion of active and passive seismic sources called PARTOS (Passive Active Ray TOmography Software). This code has been developed on the base of two well-known widely used tomographic algorithms (LOTOS and ATOM-3D), providing a robust set of algorithms. The dataset used to set and test the program has been provided by TOMO-ETNA experiment. TOMO-ETNA database is a large, highquality dataset that includes active and passive seismic sources recorded during a period of 4 months in 2014. We performed a series of synthetic tests in order to estimate the resolution and robustness of the solutions. Real data inversion has been carried out using 3 different subsets: (i) active data; (ii) passive data; and (iii) joint dataset. Active database is composed by a total of 16,950 air-gun shots during 1 month and passive database includes 452 local and regional earthquakes recorded during 4 months. This large dataset provides a high ray density within the study region. The combination of active and passive seismic data, together with the high quality of the database, permits to obtain a new tomographic approach of the region under study never done before. An additional user-guide of PARTOS software is provided in order to facilitate the implementation for new users.

    Growth pattern and daily growth increment in lanternfish (Benthosema pterotum) of the Oman Sea (2017)
    Details
    Publication Date: 2021-05-19
    Description: Lanternfish (Benthosema pterptum) is one of the most important fish species in the Oman Sea. We randomly sampled 300 myctophids from different depths in spring and winter 2009 in the Oman Sea using mid-water trawls. Male to female sex ratio was 0.36:0.64. The thin sections (60-80µm) of sagitta otoliths of the fish were prepared using polishing method. These sections showed that increment growth rings of lanternfish otolith are formed daily and the age condition is distinguishable on a daily basis. We found the life span of the species to be short (with a maximum of 349 micro-increments counted) and probably less than a year. The relationship between standard length (SL) and daily growth increment (D) was expressed as the linear equation: SL=0.87D+12.37 (R 2=0.97). The relationship between lanternfish weight (W) and daily growth increment (D) was expressed as power equation: W=0.00003D1.754 (R2=0.95). Furthermore, morphometrical characteristics of otolith including otolith weight and length and daily growth increment relationships were expressed as linear equation (R2=0.96 and R 2=0.83). The results showed that lanternfish growth rate were in the range 0.241mm/d-1 to 0.138mm/d-1 and decreased by body size and age in this range.
