The article is devoted to the organization of training of young professionals who are able to successfully perform production tasks after graduation in accordance with the requirements of industry 4.0. The development and implementation of robotics, artificial intelligence and other "end-to-end" technologies actualizes the problem of training engineering personnel. Under the conditions of the new technological paradigm, it is necessary to change the system of teaching students in universities. The practices of training future engineers to work in the conditions of industry 4.0, capable of developing the country's economy, ensuring its competitiveness at the world level, are characterized by high professionalism, initiative, creative approach to decision-making and high responsibility for the results of their engineering activities are analyzed. The problem of training such engineers lies in the conservatism of the higher education system and the underdevelopment of teachers who are able to influence the content and critically evaluate the educational programs of universities. A specific solution is proposed to improve the system of interaction between universities and employers in order to train in-demand engineering personnel, whose work can contribute to Russia's entry into the global market for the development of "end-to-end" technologies demanded by industry 4.0.

A study was made of the economic efficiency of fishing in the Murmansk region in 2013-2020. The factors of its high profitability in 2014-2020, in comparison with 2013, have been identified. An unreasonably high level of domestic prices for fish products and the possibility of their adjustment by market methods have been established. It is proposed to adjust prices taking into account the difference in the incomes of the population of Russia and the main importing countries of fish products.

The socio-economic importance of coastal fishing in the development of the economy and social sphere of the Murmansk region is shown. Proposals have been developed to improve the functioning of coastal fisheries by transferring part of the regulatory powers to the regional level. To improve the socioeconomic efficiency of the coastal fishery, the need to create a wholesale distribution center is substantiated.

The contribution of the Caspian states to the development of interstate cooperation in the field of marine scientific research is shown. The prospects for international legal regulation of scientific research of aquatic biological resources in the Caspian Sea are considered.

The history of the study of the angled-tailed shrimp, which lives in the northern part of the Sea of Okhotsk, is considered. Based on the materials collected in 2000-2020, the ecology and some features of the biology of this shrimp are presented, the course of fishing and catch is analyzed. The prospects of its industrial development are shown.

The solution to the problem of individual fishing has been discussed for many years, but so far no acceptable option has been found. There is currently no infrastructure capable of solving this issue. It is proposed, within the framework of the current legislation, an innovative infrastructure developed by the authors. In the center of the proposed infrastructure is a Municipal unitary enterprise and a Fish cooperative (artel), as well as a laboratory of veterinary and sanitary expertise, a fish market and ship repair sites. The implementation of the proposed infrastructure makes it possible to solve not only the task of individual fishing, but also a number of socio-economic problems of the Murmansk region (in particular, the revival of shipbuilding and ship repair). Preliminary economic calculations are presented.

The development of the Pacific squid fishery in the economic zone of the Russian Federation of the Sea of Japan was studied. The accumulations of squid were studied and shown both in the daytime and at night, which determine the technique and technology of fishing for the Pacific squid with trawls. Dense aggregations of squid form in the daytime over highlands, catches per haul can be up to 45 tons, and at night they are distributed in the water column, such behavior is typical for other pelagic objects, such as mackerel and sardines of iwasi. Warming of the surface waters of the Sea of Japan in the domestic economic zone was revealed, which contributes to the development of the Pacific squid trawl fishery.

Studies were carried out on the influence of the hydrological and hydrochemical regime on the species diversity and biological parameters of goby fish in the western part of the North Caspian in 2016-2018. It is shown that the species composition in these years was represented by 9 species, with a predominance of sand goby and bighead goby and with the increase in sea salinity, stenohaline fish began to appear: gray whip goby and Khvalyn goby, the number of the latter in catches increased in 2018 compared to 2017 by 16.8 times. The number and biomass of gobies in 2018 increased by 4 times compared to previous years and amounted to 2384 million copies, 16.807 thousand. t., respectively, as well as the improvement of their biological parameters, indicate the favorable state of the population, and hence the food supply for anadromous fish, in particular, sturgeon, semi-anadromous species, marine migratory herring.

European whitefish are widely used for artificial reproduction in aquaculture. Relevant is the search for alternative solutions for protein supplements in the composition of animal feed for its cultivation. A promising source of valua-ble protein is fish waste from canning industries. In the Kaliningrad region, 80% of Russian canned food "Sprats in oil" is produced. The daily amount of sprat waste is 2-10 tons. The use of protein products of hydrolysis of smoked sprat heads instead of a part of fishmeal in compound feeds for whitefish juveniles was studied in this work. Hy-drolysis was carried out by a high-temperature method in an aqueous medium to obtain two types of protein sup-plements. In the first experiments, a 5% low molecular weight peptide supplement with a protein content of 82.7% was introduced into the model feed instead of the corresponding amount of fishmeal. In the second series of experi-ments, a 10% protein-mineral supplement was introduced with a protein content of 54.5% and mineral substances of 24.0%. The experiments were carried out in a closed aquaculture system based on AtlantNIRO. After 56 days of feeding, the fish breeding, morphobiological and organosomatic parameters of the fish were comparatively studied. . The promising potential of additives as feed components has been established. The introduction of a 5% peptide additive led to an increase in the fry survival rate. The use of a 10% protein-mineral supplement resulted in higher growth rates and lower feed ratios. In both experiments, there was no negative effect on the growth and morpho-physiology of the studied fish. For more reliable results, further study of alternative amounts of inclusion of these additives in the feed is required.

This article reviews the experiment of growing two-year old three-year old carp, grass carp, silver and bighead carp in experimental ponds of EEF KSTU from May to October 2021 in order to determine their growth and adaptagenic potency. According to the results of the evaluation of growth potential disclosure of herbivorous fish, we observed similar dynamics of the rate of mass accumulation at two and three years of age. Maximum values were observed in summer (July-August) and minimum values in autumn (September-October). Close resolution of growth potency was observed for three-year-old silver and bighead carp. According to the results of the assessment of the disclosure of adaptogenic potency, the highest value of the ecological coefficient was observed for bigheaded carp (70% of the influence on growth from ecological factors). In other groups of two-year-olds, the disclosure of this factor was at an average level (39-56 %), and in three-year-olds it was at a low level (33 %). The survival rate of the study groups did not exceed 80-92%. According to the results of the study, the disclosure of growth and adaptogenic potency for two-year old three-year-old fish in ponds of EEF in 2021 was disclosed at the average level of values, the growing season corresponded to IV fish farming zone.

One of the methods of conducting experimental work to determine the coefficient of catchability of juvenile seines in relation to different-sized whitefish juveniles is considered. The method is based on fencing off part of the water area with a business curtain. The positive aspects of the method are associated with the exclusion of the influence of emigration, immigration and natural mortality of fish, as well as with the possibility of using several methods for calculating the catch coefficient (accumulated catch, catch per effort, Leslie). The comparability of the results obtained by different methods is noted, improvement of calculations by the Leslie method taking into account natural mortality is proposed. The relatively high sensitivity of the Leslie method to the degree of overgrowth of the experimental site was revealed. In general, the catch coefficient decreases with the growth of juveniles, a decrease in the size of the fishing gear and an increase in the presence of macrophytes. It has been established that whitefish juveniles prefer to stay clean of aquatic vegetation with growth.

The paper considers four nonlinear phenomena studied in the framework of the theory of catastrophes, which are present in the practice of the fleet and relate to various aspects of logistics – depending on the speed of movement of the thrust force of the ship's propulsion and the magnitude of the Cx. Their correspondence to the catastrophes of folding and assembly is shown.

The purpose of the study is to form the taste of combined minced fish and readymade culinary products. Low-field nuclear magnetic resonance (¹H-NMR) have been accepted widely as a non-destructive analytical technique in food processing technology to their sensitivity, non-invasiveness, rapidness, and cost-effectiveness. Moreover, the ability to provide real-time information on products during and after processing has been linked to the use of thice analytical technique. Timely information on quality parameters in food processing provided by online monitoring using ¹H-NMR may increase the quality of the product, improve operation process, and enhance production economy in food field. In this review, the use of online ¹H-NMR in food processing techniques, such as freezing, frying, fermentation, and internal quality analysis, is explored. Limitations and need for further development are outlined.

The work is devoted to the study of the effect of the fermentation process on the microflora composition of fermented product from the Baikal omul (Coregonus migratorius (Georgi, 1775)), produced with the use of bacterial concentrate of lactic acid bacteria Latilactobacillus sakei ((Katagiri et al. 1934) Zheng et al. 2020). It has been established that, according to microbiological indicators, fermented Baikal omul meets the requirements of regulatory documentation. The microflora of the control (without the use of bacterial preparations) and experimental (with the use of a bacterial concentrate of lactic acid bacteria) batches had significant differences.

The research of physico-chemical and organoleptic quality indicators of the black macrurus (grenadier) Coryphaenoides acrolepis caught under industrial conditions in the South Kuril subzone of the Sea of Okhotsk is presented. The analyzed samples included whole and eviscerated specimens of standard quality, as well as individual specimens with the consistency of muscle tissue characterized as «rubber-like». Comparative analysis showed statistically significant similarity of muscle tissue strength indicators before and after heat treatment, protein fraction content, moisture retention capacity, degree of protein denaturation, enzyme activity and a number of other characteristics for standard samples prepared by various methods and differing in size. Samples with a «rubber-like» consistency sharply differed in all the studied parameters except for enzymatic activity. When separating the proteins of black grenadier muscle tissue by electrophoresis was conducted, differences in the speciesspecific patterns of the compared samples were found. Assumptions have been made about the causes of the detected changes.
