A scientific framework for conservation aquaculture: A case study of oyster restoration in central California

The emerging field of conservation aquaculture focuses on the potential for incorporating aquaculture techniques into restoration. Extensive loss of oyster reefs worldwide has led to restoration initiatives that sometimes incorporate aquaculture, but few scientific studies of this approach have been published. We developed a scientific framework to determine whether aquaculture is an appropriate conservation tool, and applied it to Olympia oysters (Ostrea lurida) in Elkhorn Slough, an estuary in central California, USA. Over 12 years of monitoring, we documented precipitous declines in density, highlighting the need for restoration. We tracked settled oysters and found that growth and survivorship is high, showing that hatchery-raised juveniles have the potential to survive to reproductive age. No natural recruitment has occurred in the estuary in seven years, suggesting that this population is recruitment limited. Thus, we determined a need for conservation aquaculture. We produced juvenile oysters from local broodstock in a hatchery and settled them on native clam shells, which we attached to stakes to form small clusters that mimic natural biogenic habitat created by this species. We deployed these near the upper limit of the intertidal range of oysters, where oyster cover dominates over non-native fouling species. The outplanted oysters grew to adult, reproductive size within months of outplanting, and survivorship was generally high, providing the first new generation of oysters in this estuary in seven years. The science-based approach we implemented and our incorporation of traditional restoration principles of natural habitat structure and dominance by native species can serve as a model for conservation aquaculture for oysters and other species.

The influence of raffinose on the growth performance, oxidative status, and immunity in Nile tilapia (Oreochromis niloticus)

Infectious diseases usually occur in response to the highly intensive rearing conditions in fish farms. The use of feed additives is still one of the most practical options in the field of aquaculture. Therefore, this study aimed at evaluating the impact of raffinose on the growth rate, antioxidative status, and immunity of Nile tilapia. For 60 days, fish fed five test diets with raffinose at 0, 0.5, 1, 1.5, and 2 g/kg. The FBW was increased by feeding raffinose at 0.5 or 1 g/kg levels over the control, whereas no significances were observed among the other groups. Feeding tilapia with raffinose at 1 g/kg increased the WG and SGR and decreased the FCR with regards to the control. The activity of SOD was enhanced by feeding raffinose at all levels, while GPX and SOD were improved by 1 or 1.5 g/kg levels over the control. On the contrary, the concentration of MDA was decreased by raffinose, and the lowest levels were observed by 1 or 1.5 g/kg levels. The lysozyme activity was increased by level 1 g/kg over the other levels without significant differences with 1.5 g/kg. The phagocytic activity and index were also boosted by feeding raffinose at 1, 1.5, and 2 g/kg levels over 0 and 0.5 g/kg. Taking together, dietary raffinose increases Nile tilapia growth performances, and immune responses and 0.85–1.37 g raffinose per kg diet is recommended for this species nutrition.

Site selection for finfish cage farming using spatial multi-criteria evaluation and their validation at field in the Bay of Souahlia (Algeria)

The development of marine fish farming on the Algerian coast is facing a number of environmental and logistical constraints. In a multi-disciplinary approach, based on aquaculture activity planning and field validation, the aim of this study is to target suitable areas for the setting of floating cages for Sparus aurata breeding at the Bay of Souahlia, Algeria. Multi-criteria evaluation via GIS was applied, combining 3 sub-models (environmental, socioeconomic, and constraint sub-models). The field verification was carried out on El Mokretar Aqua farm, by comparing its position with the result of the multi-criteria evaluation and by studying the growth performance indicators, thermal unit growth coefficient, specific growth rate, and feed conversion ratio and biomass. The regeneration of the final suitability map allowed for the delimitation of the favorable area for the implantation of the floating cages, which corresponds to 32% of the total area, with 3 classes of suitability. The El Mokretar Aqua farm is located at station S11, with a significant relevance index of 0.69. The gilthead seabream reflects a good growth performance. It grows with an average weight of 5 to 305 g over a 306-day rearing period, due to the environmental conditions and the good management of the farm.

Bioengineered gold nanoparticles from marine seaweed Acanthophora spicifera for pharmaceutical uses: antioxidant, antibacterial, and anticancer activities.

In this study, we report a green synthesis of pharmaceutically active gold nanoparticles from marine red alga Acanthophora spicifera by the reduction of chloroauric acid. The formation of A. spicifera-mediated gold nanoparticles (As-AuNPs) was characterized by several analytical techniques. The crystalline and face-centered cubic (fcc) structure were confirmed by X-ray diffraction (XRD) analysis. Electron microscopy results confirmed that As-AuNPs were spherical and the average size of particles was < 20nm. As-AuNPs hold a significant level of antioxidant activities than A. spicifera extract. As-AuNPs exhibited the highest antibacterial activity against Vibrio harveyi than Staphylococcus aureus at 100µg/ml. Furthermore, As-AuNPs exhibited the utmost cytotoxicity against human colon adenocarcinoma (HT-29) cells and registered the half-maximal inhibitory concentration (IC50) at 21.86µg/ml. These findings authenticated that the synthesized As-AuNPs possess a broad spectrum of biological activities, and it can be effectively applied in the field of aquaculture and biomedical application.

Institutional perspective for doubling fish farmers’ income: A case study

Doubling farmers’ income (DFI) by 2022 has been set as a target for Agriculture sector of India. Extensive deliberations have been made on application and adoption of technologies/packages as key forces to reach the target. The responsibility is with numerous stakeholders and the specific role of Research and Development (R&amp;D) institutions in doubling farmers’ income has not been touched upon. As agriculture and allied sectors like aquaculture is a state subject, greater linkages have to be established by R&amp;D institutions to achieve the target. The present study analysed the role of R&amp;D institution in doubling farmers’ income, keeping technology as an effective tool, based on a case study of ICAR-Central Institute of Freshwater Aquaculture (ICAR-CIFA), Bhubaneswar and Krishi Vigyan Kendra (KVK)-Khordha in Odisha State, India. The results of the study delineated the ways and means for ICAR-CIFA and KVK, Khordha to achieve the target of doubling farmers’ income by developing models with existing proven technology, upscaling proven extension approaches like Farmers Field Schools (FFS) replicated as Aquaculture Field Schools (AFS), best practices to be adopted and rationalising farm innovations.

Factors contributing to the Success of Aquaculture Field SchoolsAn Economic Appraisal of Composite Carp Culture in West Bengal

Aquaculture sector is gaining momentum through its contribution towards Indian as well asworld economy in terms of nutritional and livelihood security. Carp farming is one of the most widely adopted technologies in aquaculture sector. The study was carried out in randomly selected South 24 Parganas district of West Bengal. The study aims at assessing economic viability of composite carp culture through analyzing the cost and returns of the technology. Data were collected from 142 fish farmers through personal interview. The average pond area of the farmers was found to be 1.9 acre and mean fish yield was 3.6 t/ha/yr. Rate of return on total investment (ROI) and Benefit-Cost ratio (B: C ratio) for adopters and non-adopters were worked out as 85.84%; 1.86 and 63.03%; 1.63 respectively. Supplementary feed constituted the maximum share in cost of production of fish followed by lease value of pond and pond preparation cost. The study implies composite carp culture technology as economically feasible with impressive benefit-cost ratio.

Exploring Mediterranean and Arctic Environments as a Novel Source of Bacteria Producing Antibacterial Compounds to be Applied in Aquaculture

The need to discover new natural compounds has become urgent as a possible alternative solution to contrast the spread of antibiotic resistance, also in the aquaculture field. Bacterium–bacterium inhibitory activity against bacterial pathogens relevant in aquaculture was evaluated on agar plates for bacteria isolated from cold Arctic (Kongsfjorden, Svalbard Islands; i.e., seawater and sediment samples) and temperate Mediterranean (Lake Faro in Messina and the Straits of Messina, Italy; i.e., brackish water and benthic filter-feeding organisms) environments. Cell-free supernatants (both pure and concentrated 10-fold) were further assayed and, in the case of a positive response, crude extracts were obtained and tested. After the pre-screening procedures, about 30% of the bacterial isolates inhibited the growth of at least one pathogen used as a target. The 10-fold concentrated supernatants of two Arctic Salinibacterium spp. strains and the Mediterranean Bacillus sp. PS62 (associated with the pennatulacean Pteroeides spinosum Ellis, 1764) resulted in being active against P. damselae subsp. piscicida. The crude extracts obtained from Bacillus sp. PS62 also showed inhibitory activity against the same pathogen. Our findings suggest that tested bacteria could represent a novel source of compounds to be applied to overcome pathogenesis in the aquaculture field.

Toxicological Effects of Enrofloxacin and Its Removal by Freshwater Micro-Green Algae Dictyosphaerium sp.

Enrofloxacin (ENR), a fluoroquinolones antibiotic, is widely used in the medical and aquaculture fields. Its residues in surface waters in China are high. However, few studies have evaluated both its toxicity to phytoplankton and the degradation or removal by microalgae. In this study, the growth, photosynthetic activity, and exopolysaccharides (EPS) of freshwater micro-green algae Dictyosphaerium sp. and the dynamics of ENR concentrations (0, 5, 25, 50, and 100 mg·L-1) were studied through an exposure experiment for 12 days. Results showed that the biomass and photosynthetic pigment content of Dictyosphaerium sp. increased with increasing exposure time in each treatment; however, it showed a significant inhibitory effect on the growth and pigment accumulation of Dictyosphaerium sp. compared with the control group (P<0.01). The LC50 of ENR to Dictyosphaerium sp. was (241.29±7.33) mg·L-1 after 96-h exposure, indicating that Dictyosphaerium sp. could adapt to the stress conditions of high concentration ENR. Meanwhile, when the concentration of enrofloxacin was<5 mg·L-1, it was found to promote the maximum photosynthetic rate (Fv/Fm) of Dictyosphaerium sp. On the contrary, when the concentration of enrofloxacin was>5 mg·L-1, photosynthetic inhibition was observed (P<0.01). The actual photosynthetic rate (Yield) and the maximum electron transfer rate (ETRmax) showed a trend of initially decreasing and then increasing in 12 days. It can gradually adapt to the stress conditions and recover certain photosynthetic activity after 6 days' exposure. In addition, ENR can also stimulate the EPS (RPS and CPS) release. At the end of the experiment, the removal rates of ENR in the four control groups (no algae addition groups) (5, 25, 50, and 100 mg·L-1ENR) were 7.27%, 5.56%, 5.30%, and 4.88%, respectively, while the removal rates of the treatment groups were 3.21, 3.01, 2.69, and 2.83 times of the no algae groups, indicating that Dictyosphaerium sp. had a significant promoting effect on the removal of ENR (P<0.01). Overall, our results can provide new insights for the understanding of the ecological toxicity of fluoroquinolone antibiotics to primary producers in the aquatic system and also provide new ideas for the ecological removal of antibiotic residues in water bodies and the biological resource utilization of freshwater microalgae.

Effect of the blue pigment produced by the tropical diatom Haslea nusantara on marine organisms from different trophic levels and its bioactivity

Marennine is the blue-green pigment produced by the temperate ubiquiste marine diatom Haslea ostrearia. This pigment is water-soluble and excreted in seawater during H. ostrearia growth and ageing. Previous studies demonstrated the adverse effects of H. ostrearia culture supernatant that contains marennine (Blue Water, BW) against marine organisms. In tropical waters in the Southern hemisphere, a new diatom species has recently been discovered, Haslea nusantara, which shares a peculiarity with H. ostrearia in producing a blue-green, marennine-like pigment. However, little is known about the characteristics of the marennine-like pigment from H. nusantara and its bioactivity. The present study aimed to determine spectral characteristics of BW from H. nusantara in comparison to BW containing marennine of H. ostrearia, using UV–vis spectrophotometry, and to investigate the effects of BWs from these two species on several marine organisms from different trophic levels including autotrophs (Isochrysis galbana) and heterotrophs (Artemia salina). Additionally, the antibacterial activities of these BWs were also evaluated on two bacterial pathogens that are relevant to aquaculture, Vibrio harveyi and Staphylococcus aureus. The results show that both BWs from H. ostrearia and H. nusantara at 0.5 μg mL−1 significantly reduce the growth of I. galbana. At similar range of concentration, toxicity tests reveal that the both BWs from blue Haslea species significantly increase mortality rate of A. salina to a different extent. Additionally, both BWs from H. nusantara and H. ostrearia can inhibit the growth of tested bacterial pathogens. This study provides new insight into the different toxicity in the bioactivity of pigments obtained from the two species of blue diatoms from the same genus. Our results also demonstrate the need to determine concentrations that optimize beneficial effects and critical concentrations not to be exceeded before considering the use of marennine as natural antibacterial agents in the field of aquaculture.

AQUA-TNET lifelong learning strategy changes E &amp; T attitudes towards ECVET implementation and the EQF

In 2011, the EU ERASMUS Thematic Network AQUAT-NET (representing the fields of aquaculture, fisheries and aquatic resources management) began a study on lifelong learning needs in the sector in order to find ways to tackle issues of articulation between different types of qualification frameworks. The survey (1913–1915) (37 organisations (universities, research institutions, associations and private companies providing lifelong learning (LLL) courses) from 16 European countries) examined their use of, and opinions concerning, the European Qualifications Framework (EQF) and the corresponding European Credit System for Vocational Education and Training (ECVET). The survey, published in 2015, revealed that two thirds of the respondents (65%) agreed or strongly agreed that there was a genuine need to establish the ECVET system of credit points in education and training and a majority of those respondents (58%) considered that the ECVET system of credits should be put into force as soon as possible, though with certain caveats. If the raft of new educational initiatives created by the European Union since then is considered along with the redefinition of key terminology in the EQF (i.e. competences) and the delayed rollout of the ECVET credit system, these AQUAT-NET results take on renewed significance, e.g. the admittedly low take-up rate of ECVET credit points. According to Reports and Evaluations on the state of ECVET implementation (e.g. CEDEFOP (2016) and the much later 2019 European Commission study on VET instruments ECVET and EQAVET), both the concept and the definition of ECVET credit points need to be revised (rather than removed). One acknowledged obstacle to the acceptance of the entire ECVET package lay in the absence of a large, well-organised peer learning group able to disseminate up-to-date relevant information. Within the small aquatic sciences sector, the steady flow of information concerning new lifelong learning initiatives to all stakeholders accounted for the success of the AQUA-TNET approach in promoting informed decision-making at the relevant level. This continues to be one of the recommended best practice approaches, while surveys such as ours are relegated to the vast unread mountains of EU studies.

Evaluation on antiviral activity of a novel arctigenin derivative against multiple rhabdoviruses in aquaculture

Rhabdoviruses cause devastating diseases in aquaculture, resulting in enormous economic losses. Our previous studies indicated that imidazole arctigenin derivatives possessed antiviral activities against aquatic rhabdoviruses. Based on the data of structure-activity relationship, a new imidazole arctigenin derivative, 4-(8-(2-bromoimidazole)octyloxy)-arctigenin (BOA), was designed and synthesized. And its antiviral activities against aquatic rhabdoviruses (SVCV, IHNV and MSRV) were evaluated in vitro. By comparing inhibitory concentration at half-maximal activity (IC 50), we found that BOA (IC50 = 1.11 μM) possessed a higher anti-IHNV activity than the antiviral imidazole arctigenin derivatives which were found in our previous study. Besides, BOA could cause profound inhibition of SVCV and MSRV replication. By the reduction assays on cytopathic effect, BOA exhibited a protective effect on two host cell lines. As a typical rhabdovirus, SVCV was chosen as a model to illuminate the anti-rhabdovirus mechanism of BOA. BOA was discovered to not impact directly on viral particles or interfere with SVCV adsorption. And it worked within the 2−6 h of the early phase of virus replication. In addition, after repression of cell cycle S phase and recovery of caspase-3/8/9 activities activated by SVCV, BOA inhibited SVCV-induced apoptosis and then reduced the release of viral particles at the late stage of virus replication. Altogether, BOA was expected to be a highly efficient antiviral agent against multiple rhabdoviruses in the field of aquaculture.

Factors contributing to the Success of Aquaculture Field Schools

ICAR- Central Institute of Freshwater Aquaculture (CIFA) had piloted four Aquaculture Field Schools (AFS), a model of farmer to farmer extension, in Odisha and Chhattisgarh states in India. The AFS’ are attracting farmers and stakeholders as they provide a platform to share experience and enable cross learning. In this research, an attempt has been made to identify the factors that contribute to the successful performance of AFS. Data were collected from 166 user farmers, selected randomly from the list available with operators. Five variables viz., age of fish farmer, frequency of visit to AFS, duration of visit, interaction with the fellow farmers and advocation of advanced technologies of ICAR-CIFA to other farmers were observed to be significantly contributing to yield of fish. The Multiple correlation coefficient, R=0.48, indicated that there is a significant and positive correlation between the observed and predicted value of fish yield.

Chemical composition and antibacterial activity of Algerian propolis against fish pathogenic bacteria

Five different varieties of propolis from four sites from Sétif region (East of Algeria) (Babor, Setif; Ain-Abbassa and El-Hamma), and one site from the center of Algeria (Tizi-Ouzou) were chemically analysed by gas chromatography-mass spectrometry. One hundred and two compounds were identified including aromatic acids, linear hydrocarbons and their acids, terpenes and alcaloïdes. Furthermore, the in vitro bacteriostatic and bactericidal activities of the aqueous extracts were evaluated against one Gram positive (Bacillus subtilis, used as probiotics in aquaculture) and two Gram negative (Vibrio anguillarum and Vibrio harveyi, pathogenic for fish) bacteria. The obtained results showed that all aqueous extracts of propolis inhibit the growth of B. Subtilis while the growth inhibition of fish pathogens was achieved when using higher propolis concentrations. These antibacterial properties would warrant further studies on the clinical applications of propolis in aquaculture field.&#x0D; Keywords: Bactericidal activity; Chemical characterization; Propolis; Vibrio.

Assessment of changes in land use, land cover, and land surface temperature in the mangrove forest of Sundarbans, northeast coast of India

This paper investigates the impacts of changing land use–land cover on the land surface temperature (LST) and normalized differential vegetation index (NDVI) distribution in the Indian part of the Sundarbans Biosphere Reserve by utilizing remote sensing and geographical information system. Landsat Thematic Mapper (TM), Enhanced Thematic Mapper (ETM+) and Operational Land Imager images of the year 2000, 2010 and 2017, respectively, were used to assess the essential indicators for regional environmental health employing appropriate calibrations and corrections. It was observed that there has been a marked reduction in the areas of plantation, mangrove swamp, mangrove forests and agricultural land since 2000. In contrast, an increase in sand beach, waterlogged areas, mudflat, river, and agriculture area was observed. The mean NDVI values for mangrove forests and plantation have decreased from 0.441 to 0.229 and 0.266 to 0.195, respectively, while river, aquaculture, agricultural and open scrubs classes had higher values. The rate of increase in surface LST was highest over settlements, followed by sand beaches, mudflats, aquaculture, mangrove forest, river, plantations, waterlogged areas and agricultural field. LST showed a negative correlation with NDVI values probably due to the high rate of evapo-transpiration activities of the mangrove vegetations. All these above facts distinctly substantiates that there is an increase in open patches/non-vegetated cover and that the ecosystem is under constant stress.

From Farm to Fingers: an Exploration of Probiotics for Oysters, from Production to Human Consumption.

Oysters hold a unique place within the field of aquaculture as one of the only organisms that is regularly shipped live to be consumed whole and raw. The microbiota of oysters is capable of adapting to a wide range of environmental conditions within their dynamic estuarine environments; however, human aquaculture practices can challenge the resilience of this microbial community. Several discrete stages in oyster cultivation and market processing can cause disruption to the oyster microbiota, thus increasing the possibility of proliferation by pathogens and spoilage bacteria. These same pressure points offer the opportunity for the application of probiotics to help decrease disease occurrence in stocks, improve product yields, minimize the risk of shellfish poisoning, and increase product shelf life. This review provides a summary of the current knowledge on oyster microbiota, the impact of aquaculture upon this community, and the current status of oyster probiotic development. In response to this biotechnological gap, the authors highlight opportunities of highest potential impact within the aquaculture pipeline and propose a strategy for oyster-specific probiotic candidate development.

A systematic approach to the formation of general professional competencies during the specialists’ training in the field of aquaculture

Basing on the assumption that the basic foundations of the natural science knowledge which should be developed in the process of mastering the disciplines of the educational program should be laid for the successful formation of General professional and universal competencies of future specialists in the field of aquaculture, the research goal was chosen: to study the degree of formation of the natural science knowledge among students of the specialty "Water bioresources and aquaculture”. In the written survey took part future specialists in the field of aquaculture of the first year of study (N0=60) and fourth-year students (N1=38). For statistical assessment of the results were used Fisher's φ-test and Student's t-test (p ≤ 0.01). The results showed that there were no significant differences between basic knowledge in the field of natural Sciences for the 1st-yaer and 4th-year students. The significant differences were identified in students' definition of the difference between natural science and parascientific fields of knowledge, but the best result was shown by 1st-year students. It can be concluded that pedagogical technologies used for the formation of General professional and universal competencies need to be modernized, and further research and development of new methodological approaches to teaching disciplines related to basic natural science knowledge will be promising.

Overview of the application of computer vision technology in fish farming

The issues that are currently identified in Russia during the implementation of Digital Agriculture project are considered. The main issues that need to be addressed in development of modern digital technologies in the fish farming industry using natural and artificial reservoirs are highlighted. Aqua engineering trends and scientific works of a number of teams that conduct research and use the capabilities of deep machine learning, are analyzed. Particular attention was paid to specific tasks and research results that solve applied problems in the field of aquaculture and fish farming. Conclusions are made about the prospects for implementing these objectives in Russia. The conclusions of scientific teams and new tasks set as a result of scientific experiments are considered. The main directions in the area of commercial fish farming that need active adaptation of computer vision to deal with applied problems, are identified. Questions of efficiency in introduction of neural networks of deep learning are raised, and also conclusions are drawn on introduction of the term “selectivity” to determine the relation of a data set received by a digital method, referred to quantity of the same data which would be received at their collection by means of non-digital technologies.

Investigation of Toxicity in Black Jaw Tilapia (Sarotherodon melanotheron) Exposed to Crude Oil

The toxicity effects of crude oil were investigated in the laboratory. Triplicates of (T1) 0.25mg/l, (T2) 1.0mg/l, (T3) 2.25mg/l, (T4) 5.0mg/l and (T5) 7.5mg/l concentration of crude oil exposed to Sarotherodon melanotheron species. The acute toxicity test of crude oil when tested against Sarotherodon melanotheron revealed that the derived toxicity index LC50 was 0.925mg/l. On computing Toxicity Factor (TF), using 96 hours. LC50, crude oil was found to be very toxic to the Sarotherodon melanotheron juvenile. The mean frequencies of micronucleus in S. melanotheron exposed to different concentration of crude oil ranged from 3.01±0.50 – 27.48±2.71. The lowest value was 3.01±0.50 in T0 (control) while the highest value of 27.48 ± 2.71 wasrecorded in fishes exposed to (T5) 7.5mg/l test solutions. The results obtained from micronucleus test showed that T5 had the highest number of micro-nucleated cells followed by T4 while T1, T2, T3, and T0 significantly increased with the concentration across the test chemical. Sarotherodon melanotheron showed various degrees of sensitivity in monitoring genetic damage especially in the normal nucleus (NN). The chromosomal aberrations indicate formation of vacuolated nucleus (VC), micronucleus (MN) and bi-nucleated cells (BN) showed marked increase in occurrence in the following concentrations of occurrences; T1, T2, T3, T4 and T5, respectively. Test solution of concentration T5 (7.5mg/l) was observed to possess fish with highest level of micronucleus frequencies followed by T4 (5.0mg/L). There were significant differences in increasing T5 having the highest number of micro-nucleated cells (MN) with a trend in increasing bi-nucleus cells (BN), polymorphic nucleus (PM), kidney shape nucleus (KN) and bleb nucleus (BLN) cells, respectively, as the concentration of the test chemical increased. The results also showed that there was a significant difference in the effects of the T5 and other test concentrations (T1, T2, T3, T4 and T0). The response of Sarotherodon melanotheron established that is a better model for bioassay test used as a pollution bio indicator. Pollutants even in a very low concentration if present for a long duration may affect the nucleus. Hence, the use of any kind of substances such as crude oil products and synthetic chemicals in aquaculture field should be carefully monitored and used under proper guidance.

History of bilateral cooperation in the field of fisheries between the Russian Federation and the Republic of Korea

Fisheries, known to provide food security, have played a significant role in the economy of the Republic of Korea (ROK). With an increase in population and seafood consumption, ROK has been forced to seek out new sources of seafood from abroad and locate new fishing grounds for its fishing fleet. This propelled the development of bilateral cooperation in the field of fisheries with the USSR (later Russian Federation) in 1991. Since then, bilateral cooperation in the field of fisheries has developed rapidly, especially in fishing, combatting IUU fishing, and scientific research. Unfortunately, the great potential of cooperation in the fields of fish processing and aquaculture is still undeveloped, but Russia and Korea are trying to advance it as its great potential is hard to be ignored. This article is devoted to the problem of establishing and developing bilateral cooperation in the field of fisheries between the Russian Federation and the Republic of Korea. It examines the history of the development of cooperation between the two countries in the field of fisheries in five main areas of collaboration: fishing, fish processing, aquaculture, combatting IUU fishing, and science. In order to carry out this study, the author analyzed three types of sources: statistical data, documents and reports of official institutions, and data collected from the news agencies’ archives.
