The problem of the influence of anti-Russian sanctions did not immediately affect Russian-Japanese relations in the field of fisheries, but began to manifest itself in rather unexpected ways. The impact of sanctions on the negotiation process on fisheries between Russia and Japan, the problem of non-payments is considered. Also, the impact of sanctions on the supply of Norwegian salmon to Japan, since the delivery routes passed through the sky of Russia, now it is closed to many countries. Fish products from Russia continue to be in high demand on the world market even under sanctions. Therefore, the import of fish by many countries from Russia remains high. In the Russian press, the issue of sanctions in Russian-Japanese fishing relations is covered little and insufficiently competently. The author's analysis of the problem is mainly based on publications in the Japanese media and Japanese government publications.

Coastal African countries, primarily Morocco and Mauritania, are partners of the Russian Federation in the field of marine fisher-ies and scientific cooperation plays a key role in this collaboration. It has more than half a century of history. Cooperation between Russian and African scientists makes it possible to improve the quality of monitoring of small pelagic fish stocks’ condition in the Central-Eastern Atlantic area and to manage them more reliably, including within the framework of annual meetings of the FAO Working Group on the Assessment of Small Pelagic Fish Stocks in North-West Africa. This paper presents a brief overview of scientific fishing and economic cooperation between Russia and the countries of North-West Africa.

The vast range of mackerel covers tropical, subtropical and temperate zones of the World Ocean, including the Mediterranean, Marmara and Black Seas. The article analyzes the current state of mackerel fishing in the CentralEastern Atlantic, where domestic pelagic fishing has been conducted since 1962, international – since 1964.

The article presents an account of the main life events and scientific career of Nikolai Mikhailovich Knipovich. He was born 6 April 1862 in Finland that was a part of the Russian Empire at the time, and got secondary education there. In 1885, he graduated with honors from the Saint-Petersburg University with a degree in zoology. His life was so difficult at times, that it could have pushed him to quit science. Fortunately, that did not happen. By the end of the 19^th century, he was known as a marine scientist. Participation in the Murmansk fisheries research expedition to the Barents Sea onboard the vessel Andrey Pervozvanny (1899-1901) brought him world fame. He is called the founder of fisheries research in the Russian North – and rightfully so.

The global problems of anthropogenic impact on the planet Earth and marine ecosystems, pollution in the 21st century of the World Ocean, including the Arctic seas, negatively affecting the reproduction of marine biological resources are considered. For more than half a century, the intensively developing exploitation of the bioresources of the World Ocean shelf has led to a de-crease in the number of mammals, fish, mollusks, crustaceans, algae and other valuable aquatic organisms. In many developed countries, due to economic activity and industrial pollution of coastal territories, there is a depression in the number and a decrease in intraspecific diversity, due to the loss of populations of passing marine "wild" Atlantic salmon and other aquatic organisms. Since the late 1980s, natural Atlantic salmon stocks have declined significantly. In the main spawning rivers of the Murmansk region, the content of pollutants in the spring is marked on the scale as high and extremely high levels of pollution. The oxygen content and water quality in rivers decrease, the number of saprophytic bacteria increases, the species diversity of zooplankton and phytoplankton decreases. Diseases and death of populations of spawning Atlantic salmon occur. A program has been developed to comprehensively investigate the causes of mass disease and death of Atlantic salmon populations, and to develop measures to restore a genetically healthy salmon population in the Arctic region of Russia.

The concept of bioeconomics was introduced into the practice of marine use by the UN Conference on Environment and Development in Rio de Janeiro (1992). Since that moment, bioeconomics has been considered as an important direction of the concept of sustainable development. As evidenced by foreign practice, bioeconomics has been developing in the last decade within the framework of the "blue" economy concept. The purpose of this article is to show the importance of bioeconomics in the process of increasing the sustainability of industrial fishing from a historical perspective and to discuss the accumulated scientific baggage on the problem under consideration, which allows us to move to the advanced development of industrial fishing.

Based on the materials collected in January-April 2022, the features of the herring fishery living in the northern part of the Sea of Okhotsk are considered. The areas of operation of vessels in the fishery are shown, the indicators of average catches of large and medium-tonnage vessels and the number of fishing days are given by month.

The information about the biological parameters of mussels living in various biotopes of the Tauiskaya Bay of the Sea of Okhotsk is presented. It is shown that the living conditions of mollusks in the studied areas differ. Low growth rate of mussels in the region. The Northern on Zavyalov island one is largely due to the openness of the coast, hydrodynamic activity and low water temperature, compared with other studied areas. On the littoral of lake Salty the prevailing favorable environmental conditions and the absence of wave activity contributed to a high rate of mussel growth in length and the manifestation of negative allometry in height and positive in width, characterized by a smaller convexity of the shell compared to cape Severny and bay Veselaya.

The long-toed crayfish Pontastacus leptodactylus Eschscholtz is one of the few invertebrates of freshwater reservoirs of the Altai Territory, representing a promising object of fishing. This paper provides an overview of changes in the state of cancer populations in commercial reservoirs of the Altai Territory in the period 2010-2021. The analysis of the dynamics of the main parameters reflecting the quantitative characteristics of cancer populations was carried out. The trend of decline in commercial stocks of cancer is traced, the dynamics of production (catch) of cancer by organized fishing is presented. The characteristic of the main causes of changes in commercial stocks of cancer, both natural and anthropogenic significance, is given.

Based on the results of ichthyological monitoring of VNIRO, a preliminary assessment of the work on the reaclimatization of sterlet in the upper reaches of the Dnieper River within the borders of the Smolensk region is given. Data on its occurrence in catches of smooth nets, size and age indicators, stages of maturity of gonads are given. A comparison of the nutrition composition of the Dnieper sterlet with the sterlet of the upper reaches of the Oka and Klyazma rivers is given. The dynamics of the output of juveniles, the average biomass of sterlet in the riverbed within the borders of the Smolensk region are shown. Accounting of early juvenile fish in the Dnieper for a number of years showed the absence of sterlet larvae in ichthyoplankton traps. To confirm the naturalization of this species of sturgeon, it is necessary to increase the number of ichthyological monitoring sites on the territory of the Republic of Belarus.

In recent years, the state of the Caspian roach reserves has been repeatedly discussed at different levels and sites. The number of this species is declining, catches are falling. Based on the instructions of the Volga-Caspian Scientific and Commercial Council of the Volga-Caspian Fisheries Basin, a draft comprehensive program for the conservation and restoration of roach stocks is being developed, in which it is planned to consider the imposed restrictions on fishing, the possibility of artificial reproduction, the need for indepth monitoring of the population. Observing negative trends for a number of years, understanding the social significance of the species, immediate emergency measures are needed to preserve and restore the Caspian roach in order to avoid its loss.

Significant economic damage to aquaculture facilities and marine aquatic organisms is caused by viral diseases of fish, almost a quarter of the detected viruses cause diseases. Pathogens mainly fall during the transportation of infected fish from disadvantaged farms to "clean" aquatic farms, as well as from "escaped" fish from cages to the sea, where contamination of natural salmon and other aquatic organisms occurs. When delivering fish planting material to Russia from countries with different epizootological situations, constant monitoring and forecasting of possible risks is necessary. To prevent the spread of viral infections of fish, diagnostics and prevention occupy a leading place. Laboratory diagnostics of fish diseases of viral etiology is based on the isolation of the pathogen and its identification by serological methods that require a long time and research in specialized specialized laboratories of large research institutes. More effective and highly sensitive are molecular diagnostic methods, in particular, polymerase chain reaction (PCR) with reverse transcription to detect a number of particularly dangerous viral diseases of fish. Infectious necrosis of hematopoietic tissue, infectious pancreatic necrosis, viral hemorrhagic septicemia and infectious anemia of salmon were identified by highly specific and sensitive diagnostic PCR method. The improved technique of PCR with reverse transcription makes it possible to detect pathogens in salmon and other fish both with obvious clinical signs and with hidden virus carrier.

On the example of new foreign vessels put into operation in 2019-2021 and those under construction, the design features of a new generation of vessels for fishing research are considered. Due to the specifics or the research, the projects are carefully grouped by work conducted in the Atlantic and Pacific regions. The identified information on ten projects of specialized vessels with a maximum length of 44 to 85 m was analyzed, the main characteristics of which are summarized in the table. The features of the deck-laboratory complex and the scientific equipment of a number of ships of particular interest are considered. The results of the analysis draw attention to current trends in the design and equipment of fishing R/Vs.

The article is devoted to fishing nodes, in particular, to the problems of creating their three–dimensional models, as well as digital counterparts based on them, and automation tools that allow servicing and producing nodal connections.

When storing frozen fish products, objective biological, physico-chemical and biochemical changes occur, which lead to natural loss in cold storage conditions [1; 2; 3].

Introduction of the Technical Regulations of the Eurasian Economic Union "On the Safety of Fish and Fish Products" of the EAEU TR 040/2016, Decision No. 162 of the Council of the Eurasian Economic Commission of October 18, 2016 was adopted. It defined the purpose of research to update the provisions of the "Methodology for determining the norms of natural loss of frozen products from hydrobionts during cold storage", developed by specialists of VNIRO in 2004.

The level of scientific and technical literature related to the research topic is analyzed. Unexplored areas in the technique and technology of combined fishgrowing pastes have been identified. The direction of work on improving the technology and recipes of fish-growing pastes for public catering is formulated. The relevance of the work is justified by the fact that chemically balanced fishgrowing pastes will be in high demand, and will occupy a significant segment in the market of specialized products. The article is of a research nature and is devoted to high-tech processing of secondary fish cutting resources as the basis of multicomponent fish-growing pastes. The algorithm for obtaining pastes corresponds to the sequence of technological operations proposed by the authors: cutting fish into fillets, mechanically deboning bones with cuts of meat, processing bone mass by acid method into a mineral additive, cooking the main fish mass, mixing with vegetable components, filling the shell with paste and heat treatment in a steam convector. For the first time, the possibility of manufacturing fish-growing pastes based on meat of mechanical deboning of fillet-produced fish and obtaining a product with high commodity characteristics has been theoretically substantiated and experimentally confirmed.
