    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.

    Crustal Seismicity along for the Southern Andes Volcanic Zone (LOFS) (2019)
    GFZ Data Services
    Details
    Publication Date: 2024-02-23
    Description: Abstract
    Description: The Liquiñe-Ofqui fault system (LOFS) in south-central Chile provides a natural laboratory to assess the interplay between magma/hydrothermal fluid flow and crustal deformation. Understanding these processes is of paramount importance for geothermal energy exploration and seismic hazard assessment. We deployed a dense seismic network (Sielfeld et al., 2019) at the northern termination of the LOFS in south-central Chile (~38°S) between 2014 March and 2015 June. The main aim was to better understand the significance and implications of seismic activity in relation to geological information such as the complex fault-fracture network, volcanoes, and the stress field estimated from geological data. As a result, the network was designed to monitor the northern segment of the LOFS on a more regional scale rather than concentration on the activity of one volcano. The network covered a ~200‐km‐long section of the Southern Volcanic Zone, including several Holocene stratovolcanoes (Callaqui, Copahue, Caviahue Caldera, Tolhuaca, Lonquimay, Llaima, Sierra Nevada, Sollipulli, Villarrica, Quetrupillán, Lanín (La), and Mocho‐Choshuenco). Waveform data are open and available under network code 3H from the GEOFON data centre under license CC BY 4.0.

    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)
    GFZ Data Services
    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.

    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.

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

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

    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.

    Publication Date: 2021-05-19
    Description: Caspian trout (Salmo trutta caspius) is one of valuable fishes of the Caspian sea for people living in the Northern coastal area of Iran. Since fish stock and natural resources protection is one the Iranian fisheries research objectives, the most activity on Caspian trout rehabilitation was focused on releasing thousands of smolts in the rivers discharge to Caspian Sea. Catch statistics of this species has declined over last decades thus this study on quality of provided brood stocks and producing fries with suitable quality can help rehabilitation and rearing of this valuable species. Several rivers were considered for providing brooders to keep genetic resources variety of sea stocks. In spawning season 25 (9 male, 16 female) and 30 (5 male, 25 female) brooders were collected from fishermen in Mazandaran rivers and Gyilan coasts provinces respectively. After propagation and larvae rearing, 11500 (10-15 g.) and 50000 (less than 10 g.) juveniles were released in Gyilan and Mazandaran rivers respectively.

    Publication Date: 2021-05-19
    Description: An artificial Reef is a fabricated, underwater structure, typically built for promoting marine life in areas of generally featureless bottom. Creating artificial reefs began from 2000 in southern provinces in Iran. This study has surveyed about the Bushehr and Khozestan states. The objective is to determine the effectiveness of artificial reefs in attracting and enhancing the production different aquatics through increasing of fish assemblage and fishery. The performance of artificial reefs deployed off the coast of the Persian Gulf in 10 to 15m, was evaluated. The reefs comprised of seven artificial and one control (natural) statistical tests plan in three replicates. Three types of artificial reefs were used in this study. That two were designed reefs and one was not designed or used material. The experimental plan consisted (i) Reef ball (R), designed hemispherical shaped; (ii) Laneh Mahi (L), designed pyramid shaped; (iii) Used material (U); (iv) mixed (RL); (v) mixed (RU); (vi) mixed (LU); (vii) mixed (RLU); and (viii) control site (CS). Trap nets and under-water visual census surveys were adopted for seasonal sampling of fish aggregation. Results of statistical analysis using ANOVA and T-test of the mean Catch per Unit Effort (CPUE) showed significant difference (p〈0.05) in term of computing number of fish for aggregation of fishes. The study has concluded that reef deployments have influenced favorably the fish communities and fish harvests. Therefore, the artificial reefs, especially the mixed RLU, are appropriate tools for future fishing enhancement in the Persian Gulf of Iran.

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

    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.

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

    Study on Tehran citizens behavior change in consumption of the aquatic products (2018)
    Details
    Publication Date: 2021-05-19
    Description: To understand the change in fish consumption behavior of Tehran citizens (Iran), in the year 2005, an investigation was conducted using questionnaire. Using independent random method, 316 families covering all 22 districts of Tehran were selected. The results were combined with that acquired in the year 2001 to develop marketing programs. We used Fridman, K2 tests for nonparametric statistics and Z (normal distribution) and Phi Cramer index for analysis. The results showed that the quality and freshness of the products and the hygienic state of the distributing places had the highest effects on purchase. Also, the price and packaging had the same priority as in the year 2001. No significant relationship was found between income level of the families and their fish consuming tendency. Comparing the two years of study, we found that 16.6% more people preferred packed food in the year 2005 while per capita consumption had increased from 2.8 to 3.46kg. With the information on production date and health license already available on the products, the consumers demanded dietary contents. Considering the increase in marine fishery products, the families tended to consume more of the farmed aquatics with the live selling of rainbow trout being preferred the most. The behavior of consumers and their decisions to purchase fishery products in this period depended on production directions and economic development strategies which indicated positive aquaculture development programs in the country. We recommend continuing current policies regarding marketing factors. The results also showed that uncertainly about freshness and health of the products is the main reason for purchase from the representative fishery stores. The results shows more research and advertisement can improve awareness about packing advantages and its role in decreasing wastes and creating more added values.

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

    Details
    Publication Date: 2021-05-19
    Description: The lack of sustainable management programs has resulted in the drastic decline of sturgeons stocks in the Caspian Sea in the past two decades. Legal catch quotas for all Caspian littoral states has dropped from 28500 tons in 1985 to 460 tons in 2007 while caviar production in the Caspian Sea during the same period decreased from 3000 tons to 70 tons. Caviar production in the I.R. of Iran dropped from 305 tons in 1985 to about 11 tons in 2007. The "Strategic and applied research planning for sturgeon management and conservation" was developed with the collaboration of academicians from universities, researchers, experts, fishery authorities and representatives of the executive government to maintain sustainable development and rational management of sturgeon stocks in the Caspian Sea. The preparation and development of this planning was carried out through 121 sessions (2100 person hours) A comprehensive report (375 pg) was prepared which was divided into five volumes; Volume I comprises an introduction, objectives, strategies and planning, present status of production and caviar harvest, catch and export quotas, revenue generated and release of sturgeon fingerlings, Volume II comprises analysis of the problem by constructing a problem tree with 8 broad categories to analyze 344 problems and an objective tree which is the hierarchic flowchart of objectives with 9 broad categories with 241 items, Volume III comprises a review and analysis of previous and ongoing research (414 projects) on different aspects of sturgeon during the past 40 years, Volume IV comprises prioritizing research objectives outlined by the objective tree and finally Volume V which prioritizes primary objectives for 14 executive and 10 research programs. On the basis of the evaluation of the present status and for the sustainable development and rational management of sturgeon stocks a strategic and applied research planning program was proposed and developed within the framework of three primary objectives; 1) Management and sustainable use of Caspian Sea resources (5 programs), 2) Rehabilitation and restoration of stocks (5 programs), 3) Development of aquaculture (4 programs). The applied research program for each proposed executive program was outlined in 10 programs, 42 comprehensive plans and 222 projects. The primary objective on management and sustainable use of Caspian Sea resources includes 5 programs, 14 comprehensive plans and 63 projects, while the primary objective on rehabilitation and restoration of stocks includes 4 programs, 16 comprehensive plans and 87 projects. The primary objective to address sturgeon aquaculture includes 1 program, 12 comprehensive plans and 72 projects. The impacts and outcome of each of these programs was determined and presented. It is evident that if the present situation persists, the catch figures for adult sturgeon specimens and caviar production in Iran will reach zero in 2021. But if concerted efforts are taken and the proposed strategic and applied research planning program is executed (commencing from 2009) we can put a halt to these declining trends. By producing sturgeon fingerlings to restore population abundances, by conserving and protecting them in the Caspian Sea and by conducting applied research we can produce 206.4 tons of caviar by the year 2033. Apart from harvesting caviar from the Caspian Sea we can also annually produce 3000 tons sturgeon meat and 60 tons farmed caviar starting from the year 2023. The total budget proposed for implementation of this program for a period of 14 years (2008-2022) is USD 2483 million. If this budget is allocated in time and the proposed strategic program is properly and totally implemented, we can not only save many sturgeon populations from extinction but also ensure job opportunities for 6000 fisherman, provide 1480 new job opportunities and annually produce 266 tons of caviar which will generate USD 4957 million.

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

    Details
    Publication Date: 2021-05-19
    Description: Some biological aspects of yellowfin and skipjack tuna according to catch data of traditional gillnet fisheries were studied in the north of Oman Sea during 1997-99. Based on Gonadosomatic Index (GSI) results, the spawning period or yellowfin begins in spring and reaches to the peak level in May-June. For skipjack tuna, in addition to the above mentioned spawning period, the other observed period was found in autumn-winter with a peak in January-February. The first length or maturity (LM50%) of yellowfin and skipjack tuna females were estimated 76 and 61 cm, respectively. Observation of stomach contents showed that squid was the major components of diet for yellowfin and fish for skipjack tuna. A comparison between mean length of different years and landing sites using two-way analysis of variance indicated a significant differences, The length-weight equations showed an algometric growth in tuna and isometric growth in skipjack.

    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Stock assessment of sardine and anchovy fishes in Persian Gulf and Oman Sea (Hormuzgan province) using fish population dynamics parameters and stock assessments models were carried out to estimate maximum sustainable yield (MSY) from 2010-2012. Results of 16 years (1996-2012) fisheries data analysis showed the mean of CPUE (catch/shooting) were calculated for Gill nets, Beach siene and Purse siene as 134, 988 and 2338 kg/shooting respectively. Relationships of catch and effort were determined for Qeshm area (R2=0.94) , Bandar Lengeh area (R2=0.51) and Jask area (R2=0.73) as a polynominal increasing model. Population dynamics parameters using monthly length frequency of 10540 sardine and 8232 anchovy by FiSAT II from Persian Gulf (Qeshm-Bandar Lengeh) and Oman Sea (Jask) fishing areas. Growth parameters K and L∞ of sadine (Sardinell sindensis) were estimated 1.18 y-1 and 19.1 cm in Persian Gulf and 1.11 y-1 and 19.1 cm in Oman Sea, and also for anchovy (Encrasicholina punctifer) were estimated 1.20 y-1 and 9.2 cm in Persian Gulf and 1.18 y-1 and 9.3 cm in Oman Sea. Anually, 5 cohorts for sardine and 2 cohorts for anchovy were estimated using Bhattacharya method in Persian Gulf and Oman Sea. Natural mortality (M) and fishing mortality (F) were estimated for this species, and exploitation rate of sardine were calculated as 0.58 and 0.44, and exploitation rate of anchovy were 0.54 and 0.34 in Persian Gulf and Oman Sea respectively. Length of catch (LC) were calculated 11 cm and 12 cm, and for anchovy 6.8 cm and 6.6 cm in Persian Gulf and Oman Sea respectively. Length – weight relationships of sardine and anchovy were calculated as isometric growth. Results of this study showed that populations of sardine and anchovy in Qeshm and Bandar Lengeh area are a single-unite stock, no enough evidence for discrimination of sardine and anchovy populations in Persian Gulf and Oman Sea. The mean anuall biomass of sardine and anchovy were estimated using Thompson and Bell model 190000 tones in Hormuzgan province. Maximum sustainable (MSY) of sardine and anchovy were estimated between 59721 and 98309 tones in this area. MSY of sardine were calculated 15222 and 3182 ton and MSY of anchovy were 36237 ton and 5080 ton , for minimum of estimated MSY in Persian Gulf ( Bandar Lenghe-Qeshm) and Oman Sea (Jask) respectively. Using yield per recruit of Beverton and Holt model , F0.1 were estimated averagely 1.75 for sardine and anchovy in Hormuzgan province and its showed the underfishing condition. Survey of catch and efforts trend in sardine and anchovy, defined development phase of small pelagic fisheries in Hormuzgan province.

    Details
    Publication Date: 2021-05-19
    Description: This study was aimed to investigate the effect of different doses of oral diethylstilbestrol (DES) on feminization of Nile tilapia (Oreochromis niloticus) larvae under the condition of brackish water in Bafgh fisheries research center. This Experiment was comprised of two control groups in two replicates and two experimental ones in three replicates. At the beginning of the trial, a number of 2150 larvae were randomly distributed among 10 replicates that were under treatment for 45 days. The diets in two control groups, i.e. non-treated, C1, and ethanol treated feed, C2, and the ones in two experimental groups, i.e. 200 and 400 mg DES/k of feed, E1 and E2, were administrated to 7 day post fertilization (dpf) larvae for a period of 35 days and then until day 45, the larvae were fed with ordinary feed. At the end of the trial, the gender ratio of larvae in different groups was determined by squash test in 50 randomly selected individuals from each replicate. The results showed no significant differences for gender ratios within control groups (respective male to female ratio in C1 and C2 was 47:53 and 57:43). However, the corresponding ratios within experimental ones, fed with 200 and 400 mg DES/k of feed respectively, was significantly different (P〈0.05). Noteworthy that the percent of females between two experimental groups (E1 and E2) was not significantly different (70.0 and 64.7 respectively) but it was significantly different with ratios in experimental groups (P〈0.05). The total body length and live body weight were determined at the begging and then at day 30 and 45, it was randomly measured in 20 larvae from each replicate. At the beginning of the experiment, the mean body weight and total length of larvae was 0.012 gram and 1.03 centimeter respectively. The respective averages at day 30 and 45 were significantly different among groups (P〈0.05). Survival rate was significantly different among groups (P〈0.05), being highest in E1 and E2 respectively whereas lowest in control ones (56.51 and 58.84 in C1 and C2 respectively).

    Publication Date: 2021-05-19
    Description: The Caspian Sea has a high ecological and biological value due to harboring important commercial bony fishes and sturgeons. There are more than 15 species of bony fishes (excluding kilka) which are harvested by 135 fishing cooperatives in Iranian coastal waters of the Caspian Sea and 10000 fishermen are involved in exploitation of these fishes. Annually, between 20 to 24 thousand tons of commercial bony fishes as Caspian kutum, mullets, bream, pikeperch, European carp, Caspian salmon, shads and other fish species are caught in Iranian coastal waters of the Caspian Sea. Strengths, weaknesses, opportunities and threats (SWOT) in exploitation of the bony fishes have been surveyed. SWOT results were analyzed considering the long-term development plan of the Iranian Fisheries Organization for sustainable and responsible exploitation of bony fish species. The effective strategies including rehabilitation of spawning grounds in the rivers, restocking of endangered species, controlling illegal fishing and decreasing the number of beach seine fishing cooperatives were determined as required in Iranian coastal waters of the Caspian Sea.

    Commercial catch management of spiny lobster, Panulirus homarus in the coastal waters of Sistan and Baluchestan province (2018)
    Details
    Publication Date: 2021-05-19
    Description: Management of commercial catch of the spiny lobster, Panulirus homarus Linnaeus, 1758; was studied in fishing season, from September to November 2001. P. homarus specimens were captured from different fishing sites of Ramin, Chabahar, Konarak, Puzm and west of Puzm. Carapace length and sex of specimens and presence of eggs and pleopods of females were considered. The latter factor was noticed to check of the eggs removed from pleopods. Fishing season takes about one and the half months. The maximum and minimum carapace length were observed in west of Puzm (80.04 + 9.02 mm) and puzm (76.46 6.66 mm), respectively. Minimum size limit specimens at different fishing sites were not significantly different, but frequency of them were more than years of 1999 and 2000, although fewer ovigerous females were caught. A better management of the lobster resources needs the collaboration on fishing, fisheries and research within the Iranian authorities, and also fisheries cooperation of the two neighboring countries.

Despite huge investment of government for preparation and construction of shrimp sites, only small part of present potential in southern coast of the country is under production. About 18 different shrimp species inhabit in Persian Gulf and Sea of Oman, in which 4 species have larger size, and more abundant, and harvest commercially . Penaeus semisulcatus, Fenneropenaeus merguiensis and Metapenaeus affinis as commercial species distributed throughout of Persian Gulf from mouth of Arvand River in north- west to strait of Hormoz, and also some parts of Oman Sea. While Fenneropenaeus indicus distributed mainly in coastal area of Oman Sea. Shrimp culture begin in Iran by P.semisulcatus, continued by imported Penaeus monodon, and developed by using of F.indicus. After confront to slow growth and viral diseases in 2001 (Khouzestan province) and 2005 (Bushehr Province), at the same time I.F.R.O acquired the bio-technique for production of Litopenaeus vannamei, and hence the condition for introduction the new species to the shrimp culture industry provided. In accordance for development of shrimp culture, I.F.R.O carried out various research activities, and established specific research center for this purpose. Research projects regarding brood-stock management, breeding and larvae production, grow out, water management and disease identification and treatment have been carried, and induced considerable impacts on quantitative and qualitative development of shrimp culture in the country.

    The biological study of Coregonus lavaretus of the lake of Karaj Dam (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Coregonus lavaretus is one the important species of coregonidae family. It has adipose fin and the tail fin has a deep notch. The fish is special for fresh and cold north waters and are mainly found in north hemisphere and north of Europe, Asia and America. It feeds aquatic invertebrate and zooplanktons. The mentioned species has tasteful meat and supplies the major part of fish consumption. The big fishes meat is tasteful, low fat and has a cucumber like odorous characteristics and is mostly consumed in dried and smoked forms. Since this fish is important in inland fisheries and is releasable and developing in water sources of lakes behind dams has been considered and respect to purity of water resources behind dams. In the lake of Karaj dam has been considered as the only habitat and considered to have to low biological information from October to late march 2001 for 6 months totally 82 samples were caught and studied and through this way lack of fishing in the region by determining 11 stations, the samples were collected and grown, relation between length and weight, age and length, propagation, nutrition and fertility parameters were evaluated. Most of caught fishes are 4 to 5 year olds and 3 and 4 year olds. The 4 year olds males were majority and 5 and 6 year olds females formed the dominant group. Correlation relation between age and total length in both sexes (male and female) was very significant at 1% level, of course in females the correlation was around 100%. The weight and total length in males and females that was caught both had high correlation at 1%level; of course this correlation in females had been very stronger than males. % level related to gonad weight and sexual evolution stages of females. Gonad had correlation at 5 The most absolute fecundity had belonged to 5 year old female with 19120 ovules and the lowest to 4 year old breeder. With 11496 ovules the most relative fecundity was 62.13% and belonged to 5 year old breeder and the lowest was 36.06% belonged to 4 year old breeder by increasing the quantity of ovules in breeders the sixth stage of sexual evolution the fecundity rate has been directly increased as well. % of Gonad weight was the most effective factor on absolute fecundity and according to (R2) more than 90 variations of breeders; absolute fecundity is claimable by their gonad weight. Among all traits, affecting gonad weight fecundity the breeders sexual evolution stage has been recognized the most effective factor on fish ovules diameter. Generally in oligotrophic aquatic resources they become mature before the age of 3 and in utroph aquatic resources and full of edible zooplanktons they become mature with 2 years of age. In respect to nutrition this fish eats a broad range of zooplanktons separated from surface to bed of water of dam lake and no kind of selection was seen there so that in different ecological condition it can differ appropriately to kind of foods available in different seasons so that in cold months (December to March) the food diet of this fish varies toward eating water bed living things such as tobifex.

    The crust and upper mantle structure of central and West Antarctica from Bayesian inversion of Rayleigh Wave and receiver functions (2018)

    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.

    Movements and oceanographic associations of large pelagic fishes in the North Atlantic Ocean (2018)

    Description: Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy at the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution September 2018
    Description: Highly migratory marine fishes support valuable commercial fisheries worldwide. Yet, many target species have proven difficult to study due to long-distance migrations and regular deep diving. Despite the dominance of oceanographic features, such as fronts and eddies, in the open ocean, the biophysical interactions occurring at the oceanic (sub)mesoscale (〈 100 km) remain poorly understood. This leads to a paucity of knowledge on oceanographic associations of pelagic fishes and hinders management efforts. With ever-improving oceanographic datasets and modeling outputs, we can leverage these tools both to derive better estimates of animal movements and to quantify fish-environment interactions. In this thesis, I developed analytical tools to characterize the biophysical interactions influencing animal behavior and species’ ecology in the open ocean. A novel, observation-based likelihood framework was combined with a Bayesian state-space model to improve geolocation estimates for archival-tagged fishes using oceanographic profile data. Using this approach, I constructed track estimates for a large basking shark tag dataset using a high-resolution oceanographic model and discovered a wide range of movement strategies. I also applied this modeling approach to track archival-tagged swordfish, which revealed affinity for thermal front and eddy habitats throughout the North Atlantic that was further corroborated by synthesizing these results with a fisheries-dependent conventional tag dataset. An additive modeling approach applied to longline catch-per-unit effort data further highlighted the biophysical interactions that characterize variability in swordfish catch. In the final chapter, I designed a synergistic analysis of high-resolution, 3D shark movements and satellite observations to quantify the influence of mesoscale oceanography on blue shark movements and behavior. This work demonstrated the importance of eddies in structuring the pelagic ocean by influencing the movements of an apex predator and governing the connectivity between deep scattering layer communities and deep-diving, epipelagic predators. Together, these studies demonstrate the breadth and depth of information that can be garnered through the integration of traditional animal tagging and oceanographic research with cutting-edge analytical approaches and high-resolution oceanographic model and remote sensing datasets, the product of which provides a transformative view of the biophysical interactions occurring in and governing the structure of the pelagic ocean.

    Description: Dam reservoirs have important rules in aquaculture and fish farming in many countries. In this regard, water samples of Azad Dam reservoir (Sanandaj) were collected at five stations from July 2015 to June 2016. Then, the results of 18 physico-chemical parameters were compared with the aquaculture standards and thresholds. Results showed that thermocline and oxycline was started from June and they vanished in December. Maximum level of thermal and oxygen stratified were registered during August and June, respectively. Mean of the most physico-chemical parameters were significantly different between surface and bottom layers (T-Test, p〈0.05). Mean of temperature, dissolved oxygen, total alkalinity, total hardness, pH, total suspended solid, total dissolved solid and nutrients were in range of standard threshold of different countries. As a result, based on physico-chemical parameters and with proper management decision, the dam reservoir could be considering suitable for standard pattern of aquaculture activities.

    Publication Date: 2021-05-19
    Description: Grey mullet, Mugil cephalus is one of the most famous and valuable fish on the fisheries and aquaculture industry. This species is the most suitable to introducing the southern, northern and central regions of our country due to high resistant to large variation of water salinity and temperature. On the monthly sampling period biometric data including total length and total weight recorded and length and weight classes for every sex were determined. To understanding of physiological functions and sexual development of reproductive organs, this investigation carried out with Grey mullet imported from Hong Kong by 1993. Findings of this research can be used for management of artificial breeding of this species. Daily variation of pond water temperature was recorded. Sex steroid hormones and other plasma metabolites such as Ca2+, cholesterol, triglycerides and total proteins were measured by blood sampling. Gonad samples were prepared in order to histological studies. Oocyte growth was studied by measurement of egg diameters. Measured values of cholesterol, triglycerides of blood plasma revealed that these metabolites have seasonal variation and severely deposited on the summer and mobilized on the spawning seasons. Findings of this research suggested that egg diameters, values of sex steroid hormones (estradiol and progesterone) and Calcium concentrations of fish blood plasma shortening increased a long with day length shortening.

    Description: Total catches of bony fishes in the coastal of south Caspian Sea have been ended to 1554 ton in 1382. The catch of common carp Cyprinus carpio as a one of important commercial species has been lower than others species such as mahisephid ,kolmeie and kafal. From commercial catch point of view, the catch of kolmeie is not very important, so that its catch was included only 2% of total bony fish catch in three provinces which are located in south of Caspian sea . In spite of lower common carp catch, in comparison with total bony fish catch in Golestan province more thanb70% catch was belong to Common carp. The higher catch kolmeie among three provinces was related to Guilan with 46% of total catches. Seasonal changes of common carp catch showed maximum and minimum catch were in April 83 and December 82 respectively. The most of (CPUE) was in April 83 and September, October 82. The trend of kolmeie catch showed low fluctuation. Three age groups were specified in kolmeie age composition high and low percent observed in 2 and 3 age groups respectively. Result of biometric information common carp showed most of catch was under standard fisheries catch.

    Description: Regarding the natural potential and socio-economic advantages of aquaculture development, extension of aquaculture has been raised as one of the priorities of the second to fifth national programs of the Islamic Republic of Ira in the fisheries sector in the past ten years. Proliferation and aquaculture development also plays an important role in increasing employment, exportation, and rural development in rural areas. Although the physical capacities of aquaculture development may be clear, it is necessary to analyze the profitability of farmers and fish market as well. In recent years, reproduction and breeding of new species, in order to increase the income of farmers, have been put on the agenda of the Fisheries Research Institute. In order to increase the maximum utilization of production capacity and increase the warm water pond valume per unit area of land, three species of Indian carp has been imported. The main problems of aquaculture economical research include inadequate information and lack of the collaboration between different experts and aquaculture farmers. The objective of the research was to survey of economical aspects for culturing the imported Indian carp. The fingerlings of the imported species were transferred to the target centers, Southern aquaculture Research institute and Inland waters Aquaculture Research institute. The experiment was carried out as three treatments in triplicates for 9 months. To determine the cost of production and the share of the cost of production factors for farmed fish carp, including the cost of labor, cost of fingerlings, feed and fertilizer costs, maintenance costs, energy costs, depreciation of structures, equipment and buildings for administrative and other costs; past experiences, information and other resources and external experiences questionnaire was employed.

    Description: Dramatic depletion in number of black lip pearl oyster, Pinctada margaritifera in their natural beds despite almost two decades of catch prohibition, encouraged researchers of Iranian Fisheries Research Organization to find a scientific solution to restock the lost oysters. Following successful artificial propagation and producing spat, finding the sites that secure good growth and survival is very important. We tried to compare the growth and survival of oysters in two old natural beds, Michaeil and Hendourabi Island in the Northern part of Persian Gulf. After 14 weeks of settlement spat with an initial size of 16.85 ± 2.85 mm were randomly divided into 2 groups, in each group containing 600 individuals that were in triplicate. One group was transferred to Michaeil and Hendourabi and both groups were set at a depth of 10 m and kept for a year. Juvenile oysters at Michaeil sized 73.35 mm were almost 2 cm larger than at Hendourabi (P〈0.05) after a year of culture. Mortality rate was 20 % in Michaeil that was two times higher than at Hendourabi. Daily growth rate (DGR) showed similar trend during the culture period in both culture sites while it was faster in Michaeil. Maximum and minimum DGR were recorded in May and October in Michaeil with rate of 0.32 mm day-1 and in Feburary in Hendourabi Island with a rate of 0.01, respectively. Linear model was the best model for predicting the length of oyster over the time in both sites. Hinge length and thickness were both bigger in Michaeil, however, length was more stable to show the difference between two sites. More nutrients in Michaeil, that appeared to reduce visibility through the year (P〈0.05) may justify the results of faster growth rate in this site while more sediment on the shells of this area could be a reason of higher mortality rate. This research concludes that both sites are good for pearl oyster culture, however, using new culture methods and equipments that reduce the sedimentation rate on the shells give higher priority to the Michaeil.

    Details
    Publication Date: 2021-05-19
    Description: Aras dam reservoir situated in the northwest of Iran, west Azarbaijan province, is the only water resource of Astacus leptodactylus harvest in the country that more than 250tons of this species were exported to different countries all over the world, annually. On the other hand, one of the polices of Iranian Science Fisheries Institute is the release of this species into other water resources in the country and for this purpose, the study of risky diseases such as Crayfish pest ( Aphanomysis astasi ) and other zoonotic diseases are considered as the research priorities of aquaculture development of the country. This study was carried out to health screening of Astacus leptodactylus at Aras dam reservoir from winter 2013 to fall 2014. In this regard, A total of 394 harvested livefreshwater crayfish Astacus leptodactylus (255males, 139females) weretested. 9 epibionts and parasites peritrich protozoans were identified. From Metazoan parasites group, Branchiobdella kozarovi with incidence rate of (100%) in obtained samples was the only isolated organism from this group that identified up to species level. There was a heavy damage in gills of samples with Aeolosoma hemprichi (Annelid) in winter with90% prevalence. Furthermore, Other Epibiont fouling organisms such as Rotatoria; free living nematods and suctoria were observed in this survey. The fungi study of the lesions and melanized spots of mentioned samples revealed their infection to Penicillium expansum; Aspergillus flavus; Alternaria sp. ; Fusarium sp. and Saprolegnia sp. The results of bacterial study confirmed the presence of pathogen bacteria in Astacus leptodactylus. The most frequency percentage ( 15.16%) in hepatopancrease were related to Aeromonas hydrophila and the least one ( 1.37%) were due to Yersinia bacteria . Also, only Aeromonas hydrophila and Staphylococcus aureus were isolated and identified from heamolymph, respectively. The results revealed that the combination of Salmonella typhi, Escherichia coli and Staphylococcus sp. has caused the most infection rate while. Yersinia ruckeri and Salmonella typhi has caused the least infections in Astacus leptodactylus. According to the isolation of 6 bacteria species from hepatopancreas and 2 species from heamplymph , it can be concluded that hepatopancreas enjoyed the higher infection rate compared to haemolymph in the obtained samples.

    Providing frozen minced fish meat (2018)
    Details
    Publication Date: 2021-05-19
    Description: Frozen minced meat is an important fish industry in Japan and it's neighbouring countries like Korea, Taiwan and China. The annual production of minced fishmeat in Japan was 35400 tons in the year 1965 which increased rapidly after three years to 137000 tons in 1963. At present the trade of this product in the world has reached 1 million tons. 20 years ago the frozen minced meat industry in Japan consisted of 55 factories and 2 fishing vessels. Fishes which were not suitable to be used to prepare fish paste were made use of in this industry. These fish include Horse Mackerel, Hasoon and Alaska polak. The minced meat of these fish was used to make various fish pastes, fish sausages etc. The Fisheries Research Center in Guilan province in the southern coasts of the Caspian Sea has done a lot of work on minced meat of the small pelagic fish kilka (Clupeonella sp.). The minced meat of kilka has a gelatinous property and has a better taste and flavour as compared to minced meat of other fishes. The Dark color of the minced meat is due to the dark meat along the backbone which is mixed with the fish skin. The fish paste cannot be completely deodorised during the process of making because although repeated washings will make the color of the meat lighter, it will deteriorate it's flavour and taste. The fish to be minced is first cleaned to remove it's bones and entrails. It is washed properly and the after water has been drained off it is minced. The fish can be minced without being washed too. Additives are added to the minced meat and it is then frozen. This minced meat is called surimi, and this product can be used to prepare fish paste. This fish paste which contains starch and spices can be used to prepare sausages, fish burger, fish cake, fish ball, fish cutlets, etc. The structure consistency, flavour and taste of fish paste differs in fishes and is effective in it's gelatinous property. The products obtained from frozen minced fish meat have a good quality, suitable taste, flavour and appearance acceptable by marketing standards especially because most of them are ready to consume or easy to cook. The annual consumption of fish in Iran which is 4.3 kg per head as compared to the world consumption of 13kg per head can be increased by offering the products prepared from frozen minced fish meat.

    Sound speed and its attenuation in the Persian Gulf (2018)
    Details
    Publication Date: 2021-05-19
    Description: High quality of commercial and research uses of acoustical methods in fisheries need to have enough information about sound speed variations, Ray tracing and attenuation rate in the water. In this paper we focused on sound speed variation with depth versus physical properties of Bandar Dayer waters (NE of Farsi island and about 50 kilometers south of Delware; 28.2 N & 50.58 E) and calculation of attenuation rate. Importance of this area is for the Gulf currents, which cover this region. The results of this research show that up to 11 meters depth sound speed remain constant while depth increases and temperature decreases. After this depth sound speed decreases which is for decreasing in salinity and temperature. Sound attenuation profiles show that the most attenuation rate is at 17 to 27 meters depth.

    Status of fish Consumption per capita of Tehran citizens (2018)
    Details
    Publication Date: 2021-05-19
    Description: Status of fish consumption was analyzed by completing the 295 questionnaires in all 22 metropolitan regions of Tehran from different households in 2008. After reviewing the descriptive and statistics analysis along with the non-parametric statistics, the fish consumption per capita was extracted through formulas. The average and mode of purchasing of each household occurs 11 times per year with 5.1 Kg in each time . Considering the higher fish consumption growth rate in Iran, the sequence of interest in all kinds of protein is as follows: poultry, mutton, beef, Trout, wild fishes and Chinese carps. The highest interest of households to buy fish more than other protein resources is due to the nutrient value of it. An average of 33.2% purchasing is dedicated to the farmed fish. 59% of purchasers are interested to buy packed up fish products and pay attention to the label of nutrient values on the product package. Fish consumption per capita is 13.3 Kg, which is divided to 6.4 kg for farmed fishes, 5.8 Kg for wild fishes and 1.1 Kg for canned fish. The higher consumption per capita of Tehran citizens in comparison with other people from other cities, who are living in Tehran, is because of their tendency and freshness of farmed fishes.In contrast, the consumption of canned and wild fishes among people of littoral regions who live in Tehran is higher than others.

    Details
    Publication Date: 2021-05-19
    Description: The project is funded by the CASPECO Project which is the Third Phase of the GEF supported project in the Caspian Sea region titled “The Caspian Sea: Restoring Depleted Fisheries and Consolidation of a Permanent Regional Environmental Governance Framework” , and implemented by the Iranian Fisheries Research Organization (IFRO) in partnership with four Coastal Research Centers affiliated to IFRO, Coldwater Fishes Research Centre (CFRC).The project's objective is to improve the conservation and restoration of Caspian Salmon (Salmo trutta caspius) stocks. In accordance with IUCN criteria Caspian Salmon is placed in the red list of endangered fish. In the recent decades the destruction of habitats for juveniles, reduction of genetic diversity and fish immune system were main causes of the Caspian salmon decline. Numbers of public meetings were held with participation of fishing communities’ representatives, experts, relevant local authorities and experts of the IFRO and Iranian Fisheries Organization (IFO), Iran Environment Protection Organization (IEPO), Water Resource Management (Ministry of Energy) and University senior professors, in order to create interaction and understanding of the project objectives. Educational awareness and extension program were conducted with the involvement of fisheries communities, private sector and NGO associations. The results of the project suggests that cross-sectoral coordination for sustainable fisheries can be achieved through building partnerships and enhancing communication between the environment, private , fisheries sectors and academia. Cross-sectoral cooperation through this project improved public awareness on growing risks facing Caspian Salmon from different sources including local sources (illegal fishing and over-fishing, urban wastewater, environment destruction, industrial pollutants, pollution of air and water resources), new emerging and invasive organisms, climate change, implications of the Caspian salmon population decline on economic and social affairs of the people who depend on them for their livelihood and food security and their role in fish stock protection. The project, through its capacity building, extension and educational programs and efforts to link science to management, could translate scientific findings into an action agenda for managers and policy makers that can bring an improvement in the future of the Caspian Sea salmon stock.

    Details
    Publication Date: 2021-05-19
    Description: Carp fishes culture is one of the most important subsector fisheries industry in Khouzestan province. Every year in summer high mortality occurred in carp fishes farms specially in silver carp of north Khouzestan province. Inspection of silver carp for identification microorganisms agents (Bacteria, Fungi, Parasite and virus: SVC,KHV), determine total plate count, examination physic chemical factors of farms water, histopathology, identification planktons, the main objectives of this study, which was held in 2012. 180 silver carp from 5 farms (10 ponds) with high mortality in years ago were collected in north Khouzestan province and then differents parts of fish body including: intestine, gills, body surface, eyes and liver were examined. Physico chemical parameters and plankton sampled monthly. Physico chemical parameters of water were measured all over culture period for 960 times as follows: Do(4.45-8.5 ppm), BOD5(1.1-9.25 ppm), temp(19-33•c), pH(6.82-8.6), total hardness(348-10053), turbidity(5-56 FTU), Amonia(0.001- 0.06 ppm) and co2( 0.88-13.2). From a total 180 fish examined, 136 (75%) showed unknown algae infestation and 126 (70%) showed parasitic (Dactylogyrus, Gyrodactylus and metacercaria Diplostomum). The results of biotic parameters in farms showed that cyanophycae (Cylindropermopsis, Merismopedia and Nitzeshia) were the most group of phytoplanktons. Histopathological studies have shown necrosis in tobules kidney, degeneration hepatocyte and hyperplasia in gill cells and also results demonstrated the mean of total plate count (0-376 CFU/ml103). 60 samples with sighn severe hemorrhagic on surface body were collected for virology studies by PCR procedure (IQ2000 kit) and have shown which 3 sample suspected to KHV but SVC was not identified.

    Description: In order to come up with the responsible fishing pattern, there was a need to identify some of the biological characteristics and population dynamic parameters of yellowfin tuna, skipjack and longtail tuna in the Persian Gulf and Oman sea. Occurrence of empty stomach was high in all the specimens obtained from the gill net fisheries. Purple back flying squid was the most dominant prey species observed in the yellowfin tuna study (61% in males and 57% in females). The length of maturity (Lm50%) for yellowfin tuna was estimated 76 cm , 62.5 cm skipjack and 62.5 cm longtail tuna. Length range of skipjack was from 31-100 cm and bony fishes were the most dominant prey species observed in the skipjack. The monthly gonad somatic index was driven higher values after June which could be indicated as spawning period. The catch per unit of effort of three purse seiners (Azadegan 1, 2, 3) was compared in 1998- 2000. The species composition was 47% yellowfin tuna, 51% long tail tuna and 2% skipjack.

    Publication Date: 2021-05-19
    Description: Natural potential of the increase in abundance is identified for artemia populations, based on the analysis of «inherent rate of natural increase in abundance» (r) change. It can be considered as the quantitative assessment of the pressure degree of natural factors on artemia populations. As an example of increase in population abundance, the data are presented that were obtained for A. salina populations in 8 saline lakes of Crimea (Russian Federation). Based on the study of seasonal dynamics of artemia population abundance in the lakes, the values (r) were estimated for different time spans during the growing season. Calculations for r values for the total growing season of the populations showed that the total ratio between mortality and birthrate is negative for all lakes. It can be assumed that maximum rate of increase in abundance of natural artemia populations is determined by the ratio of their definitive weight and average weight of an individual in a population. The analysis indicated that average weight of an individual in a population of A. salina in various water bodies and in different years varied from 0.23 to 0.53 g, i.e. changed in 2.5 times. Under extreme values of Wav/Wmax, the rmp appears to be equal to 0.0187 and 0.0046, respectively. Upon comparison of two extreme options, it can be noted that the increase of Wav/Wmax in 2.5 times leads to the decrease of rmp in 4 times.
    Description: На основе анализа изменения «врожденной скорости естественного увеличения численности» (r) изучено, в какой мере в популяциях артемии реализуются природные потенции увеличения их численности. Ее можно рассматривать как количественную оценку степени давления природных факторов на популяции артемий. В качестве примера роста численности популяции были приведены данные, полученные П.М. Вороновым для популяций A. salina в 8 соленых озерах Крыма. На основе изучения сезонной динамики численности популяций артемий в озерах были рассчитаны значения (r) для отдельных отрезков времени в течение вегетационного сезона. Расчеты значений r для всего вегетационного периода популяций показали, что во всех озерах суммарное соотношение между смертностью и рождаемостью имеет отрицательный знак. Можно допустить, что максимальная скорость увеличения численности в природных популяциях артемий определяется соотношением их дефинитивного веса и средним весом особей в популяции. Анализ показал, что средний вес особи в популяции A. salina в разных водоемах и в разные годы колеблется от 0,23 до 0,53 г, т. е. изменялся в 2,5 раза. При крайних значениях Wср/Wmax величина rmp оказывается равной, соответственно, 0, 0187 и 0,0046. Сравнивая два крайних варианта, можно отметить, что при увеличении Wср/Wmax в 2,5 раза это приводит к уменьшению rmp в 4 раза.

    Transferable drug resistance plasmids in fish pathogenic bacteria. (2018)
    Aquaculture Department, Southeast Asian Fisheries Development Center
    Details
    Publication Date: 2021-05-19
    Description: Chemotherapeutic agents have been developed for treating bacterial infections and have been widely used for cultured fish for the last 30 years in Japan. The extensive use of chemotherapeutants has resulted in an increase in the occurrence of drug resistance in fish-pathogenic bacteria and also in the bacterial flora of the intestinal tract of cultured fish. The kinds of chemotherapeutants used are correlated with the occurrence of the corresponding drug-resistant genes in fish-pathogenic bacteria. Almost all multiple-drug resistant strains are carried on the transferable R plasmid, although resistance in fish pathogens to nitrofuran derivatives and pyridonecarboxylic acids is associated with a chromosomal gene. The DNA sequences of R plasmids generally differ depending on the species of fish pathogen. Exceptions are the R plasmids of Aeromonas hydrophila and A. salmonicida, which have the same resistance markers as chloramphenicol, streptomycin, and sulfonamides (SA); and the R plasmids of A. hydrophila and Edwardsiella tarda, which have the same resistance markers as SA and tetracycline. The fish pathogens A. hydrophila, A. salmonicida, E. tarda, Enterococcus seriolicida, Pasteurella piscicida, and Vibrio anguillarum are all widely distributed in fish farms in various areas, and within each species the R plasmid has an identical DNA sequence. The chloramphenicol resistance (cat) gene of the R plasmid from Gram-negative bacteria was classified into CAT I, II, III, and IV according to the DNA sequence. The cat gene of P. piscicida was classified as CAT I, those of A. salmonicida and E. tarda were classified as CAT II, and that of V. anguillarum was classified as CAT II or IV, depending on the time the strains were isolated. The tetracycline-resistance determinants (Tet), which occur in six classes (Tet A through Tet G), were class D in the R plasmids obtained from strains of V. anguillarum that were isolated from 1989 to 1991. The Tet for strains of V. anguillarum isolated from 1973 to 1977 was classified as Tet B, while for strains isolated from 1980 to 1983 it was classified as Tet G.

    Analyzing the effects of aquaculture and rebuild aquatics stocks on fisheries development in the Caspian Sea (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-12-05
    Description: Using SWOT analysis with traditional matrix and quantitative matrix methods, the strategies to benefit from strengths and opportunities to vanishing weaknesses and decrease of threats for strategic management of aquaculture in Iranian Northern provinces was surveyed. Utilizing researches held in fisheries research centers and existence of aquaculture experts in vicinity, activation of veterinary organization in production and post production, and entering new brood stocks with desirable growth are the main strategies for developing rainbow trout and Chinese carps culture in Iranian Northern provinces. In sturgeon fishes culture, independence of farms from fingerlings produced by governmental complex and diversification the cultured fishes using new species and hybrids can develop this part of aquaculture. Avoiding illegal fishing in sea and rivers, preserving the population of Caspian Sea fishes, entering new fish species which their resources are decreased extremely to breeding and fingerling production cycle, and using pike perch and bream while they migrate to Anzali Lagoon from Caspian Sea, instead of freshwater brood stocks will cause the output of sea enhancement and sea ranching activities to increase, and fisheries return coefficient of these fishes will rise. Using quantitative matrix and scoring method, it was defined that aquaculture in Iranian Northern provinces are extremely approved and acceptable and the score of strengths is more than weaknesses and opportunities more than threats. By using strategic management, these activities can be more developed.

    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)

    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 New England fishing industry is examined in terms of the capacity of the fishing fleet, of the processing plants, and of the transportation system. Limitations on the capacity of the industry, and its capability and flexibility, are explored in terms of social, economic and technical aspects. The study is based on interviews with fishermen, buyers, processors and distributors, and on data made available by the National Marine Fisheries Service. Although the fisheries is in a state of expansion and both vessels and plants have a greater capacity than is now being used, the major problems that may restrict expansion in both fishing and processing are quality control, species selection and market development.

    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.

    Least-squares reverse time migration in elastic media (2017)
    Oxford University Press
    Details
    Publication Date: 2017-01-01
    Description: Elastic reverse time migration (RTM) can yield accurate subsurface information (e.g. PP and PS reflectivity) by imaging the multicomponent seismic data. However, the existing RTM methods are still insufficient to provide satisfactory results because of the finite recording aperture, limited bandwidth and imperfect illumination. Besides, the P - and S -wave separation and the polarity reversal correction are indispensable in conventional elastic RTM. Here, we propose an iterative elastic least-squares RTM (LSRTM) method, in which the imaging accuracy is improved gradually with iteration. We first use the Born approximation to formulate the elastic de-migration operator, and employ the Lagrange multiplier method to derive the adjoint equations and gradients with respect to reflectivity. Then, an efficient inversion workflow (only four forward computations needed in each iteration) is introduced to update the reflectivity. Synthetic and field data examples reveal that the proposed LSRTM method can obtain higher-quality images than the conventional elastic RTM. We also analyse the influence of model parametrizations and misfit functions in elastic LSRTM. We observe that Lamé parameters, velocity and impedance parametrizations have similar and plausible migration results when the structures of different models are correlated. For an uncorrelated subsurface model, velocity and impedance parametrizations produce fewer artefacts caused by parameter crosstalk than the Lamé coefficient parametrization. Correlation- and convolution-type misfit functions are effective when amplitude errors are involved and the source wavelet is unknown, respectively. Finally, we discuss the dependence of elastic LSRTM on migration velocities and its antinoise ability. Imaging results determine that the new elastic LSRTM method performs well as long as the low-frequency components of migration velocities are correct. The quality of images of elastic LSRTM degrades with increasing noise.

    The dynamic response of prone-to-fall columns to ambient vibrations: comparison between measurements and numerical modelling (2017)
    Oxford University Press
    Details
    Publication Date: 2017-01-01
    Description: Seismic noise measurements (ambient vibrations) have been increasingly used in rock slope stability assessment for both investigation and monitoring purposes. Recent studies made on gravitational hazard revealed significant spectral amplification at given frequencies and polarization of the wave-field in the direction of maximum rock slope displacement. Different properties (resonance frequencies, polarization and spectral ratio amplitudes) can be derived from the spectral analysis of the seismic noise to characterize unstable rock masses. The objective here is to identify the dynamic parameters that could be used to gain information on prone-to-fall rock columns’ geometry. To do so, the dynamic response of prone-to-fall columns to seismic noise has been studied on two different sites exhibiting cliff-like geometry. Dynamic parameters (main resonance frequency and spectral ratio amplitudes) that could characterize the column decoupling were extracted from seismic noise and their variations were studied taking into account the external environmental parameter fluctuations. Based on this analysis, a two-dimensional numerical model has been set up to assess the influence of the rear vertical fractures identified on both sites on the rock column motion response. Although a simple relation was found between spectral ratio amplitudes and the rock column slenderness, it turned out that the resonance frequency is more stable than the spectral ratio amplitudes to characterize this column decoupling, provided that the elastic properties of the column can be estimated. The study also revealed the effect of additional remote fractures on the dynamic parameters, which in turn could be used for detecting the presence of such discontinuities.

    Imaging of first-order surface-related multiples by reverse-time migration (2017)
    Oxford University Press
    Details
    Publication Date: 2017-01-01
    Description: Surface-related multiples have been utilized in the reverse-time migration (RTM) procedures, and additional illumination for subsurface can be provided. Meanwhile, many cross-talks are generated from undesired interactions between forward- and backward-propagated seismic waves. In this paper, subsequent to analysing and categorizing these cross-talks, we propose RTM of first-order multiples to avoid most undesired interactions in RTM of all-order multiples, where only primaries are forward-propagated and crosscorrelated with the backward-propagated first-order multiples. With primaries and multiples separated during regular seismic data processing as the input data, first-order multiples can be obtained by a two-step scheme: (1) the dual-prediction of higher-order multiples; and (2) the adaptive subtraction of predicted higher-order multiples from all-order multiples within local offset-time windows. In numerical experiments, two synthetic and a marine field data sets are used, where different cross-talks generated by RTM of all-order multiples can be identified and the proposed RTM of first-order multiples can provide a very interpretable image with a few cross-talks.

    Post-seismic velocity changes along the 2008 M7.9 Wenchuan earthquake rupture zone revealed by S coda of repeating events (2017)
    Oxford University Press
    Details
    Publication Date: 2017-01-07
    Description: We investigated post-seismic velocity changes within the fault zone of the 2008 M 7.9 Wenchuan earthquake using coda wave data of repeating small earthquakes. We employed template matching and grid search methods to identify well-defined repeating earthquakes in order to minimize artefacts induced by variations in source location. We identified a total of 12 isolated patches in the fault zone that ruptured more than twice in a 1 yr period after the M 7.9 earthquake. We applied the coda wave interferometry technique to the waveform data of the 34 identified repeating earthquakes to estimate velocity changes between the first and subsequent events in each cluster. We found that major post-seismic velocity changes occurred in the southwestern part of the rupture area, where the main rupture was initiated and characterized by thrust motion, while the Beichuan area in the northeastern part of the rupture zone appears to experience very little post-seismic velocity changes.

    Broad-band Rayleigh wave phase velocity maps (10-150 s) across the United States from ambient noise data (2017)
    Oxford University Press
    Details
    Publication Date: 2017-01-07
    Description: In this study, we demonstrate the feasibility of imaging broad-band (10–150 s) Rayleigh wave phase velocity maps on a continental scale using ambient noise tomography (ANT). We obtain broad-band Rayleigh waves from cross-correlations of ambient noise data between all station pairs of USArray and measure the dispersion curves from these cross-correlations at a period band of 10–150 s. The large-scale dense USArray enables us to obtain over 500 000 surface wave paths which cover the contiguous United States densely. Using these paths, we generate Rayleigh wave phase velocity maps at 10–150 s periods. Our phase velocity maps are similar to other reported phase velocity maps based on ambient noise data at short periods (〈50 s) and based on earthquake data at intermediate/long periods (50–90 s). This study extends ANT from short/intermediate periods (〈50 s) to long periods up to 150 s in a continental scale of the USA. These broad-band phase velocity maps from ANT can be used to construct 3-D lithospheric and asthenospheric velocity structures.
