Abstract. Steady growth in the popularity of the service for the delivery of prepared food to consumers from catering establishments has been noted in all regions of the Russian Federation for several years. The fact that this service falls under the object of regulation of the food legislation of the Russian Federation requires its suppliers to plan and manage this type of activity. It is advisable to manage the delivery of catering products to customer orders using a process approach based on global experience in the effective use of quality management systems by entities engaged in various types of economic activity. The process approach to management involves monitoring and measuring process indicators, their subsequent analysis and assessment, for which it is necessary to have an assessment base that ensures monitoring and all of the above actions. The main hypothesis of the study is the development of an assessment base for the process "Delivery of catering products to customer orders" and the formation of a mathematical apparatus for assessing its results based on the requirements of GOST R 71162-2023 "Delivery of catering products to customer orders". The developed approach to the formation of an assessment base used for monitoring, measuring, analyzing and evaluating the service provided by a public catering enterprise for the delivery of ready-made food to the consumer allows enterprises to carry out economic activities in accordance with the requirements of the legislation of the Russian Federation, avoid administrative offenses, and ensure the consumer's right to high-quality and safe products.

Keywords: public catering products, delivery, food products, assessment base, effectiveness

Abstract. In the development of the direction of mechanical activation of salt solutions, in particular when salting the Far Eastern chum salmon and achieving satisfactory results, this work reveals the next stage of the study. In commemoration of this, the main goal is concentrated on identifying the prospects for the use of mechanically activated salt solutions in salting various types of fish and their comparative characteristics. Deepening in this direction during salting in the species differences of fish, allowed us to more objectively present the results obtained, confirm the relevance of using sea water and mechanical activation in this process, define the effectiveness of a certain type of fish. The following types of frozen fish are presented as raw materials: Far Eastern chum salmon, Olyutor herring, Far Eastern flounder. Combinations of fresh water (filtered) with salt and sea water (filtered) with salt were used as salt solutions, which were subjected to mechanical activation before the salting process. The quality of salted fish was assessed using a range of indicators: organoleptic, physicochemical, microbiological, and rheological. impurities, analysis of their properties, as well as recommendations on the selection of filter media.

Keywords: classification, pollution, impurities, sea water, bulk filtration, sampling, indicators, photometry

Abstract. The article presents experimental studies on optimizing the composition of culinary fish products based on minced salmon. The changing factor is the mass fraction of the secondary caviar raw materials introduced, which is formed as a result of punching salmon hawks. Organoleptic parameters, physical characteristics (hardness) and the cost of the raw material set were selected as particular responses. As a result of the experimental and calculated data, the optimal value of the mass fraction of secondary caviar raw materials added to the stuffing mixture is 20 %. Taking into account the comprehensive qualitative assessment of the sample of culinary fish products containing 20 % of secondary caviar raw materials, this recipe of cutlets can be recommended for implementation at enterprises of the fishing industry.

Keywords: culinary fish products, formulation, mass fraction, secondary caviar raw materials, optimization

Abstract. The article provides a brief overview of the scientific literature, showing the need to find acceptable methods for species analysis of fish raw materials. Using the example of the genus Macrurus (Macrourus), three species Small-eyed macrurus (Albatrossia pectoralis), Black macrurus (Coryphaenoides acrolepis) and macrurus of an unidentified species, the results of species differences in sensory parameters are presented. The authors developed a structural scheme for the gradation of individual indicators of fish muscle tissue, which served as a tool for the verbal description of sensory properties. To increase the volume of scientific information, a Hedonic assessment and the number of Lexical units were established. Using the comparison method, the magnitude of the Difference was estimated and expressed by the number of dimensionless units per each indicator studied. A comparison of the convergence of the sensory parameters of the studied fish showed the presence of differences in their individual indicators, the effect of which on the species classification depends on the composition of the comparison pairs. In the studied fish of the same species, the differences cannot affect the participation in the species classification. There are many differences in the paired comparison of fish of the same species with fish of an unidentified species, and their use in species classification is possible. The substitution of sensory properties for lexical units is manifested in a decrease in the volume of information material by reducing the means of description (words, phrases, sentences, words + phrases) to the meaning of one unit. As a result, this leads to a reduction in the duration of the experiment, for example, in the search for Differences by paired comparison. When finding the number of differences between the study samples, a verbal description of sensory properties has an advantage over hedonic assessment and lexical units, since, in addition to numerical values, it makes it possible to assess the nature of the indicator and its severity. An intraspecific estimate of the number of differences established between raw and heat-treated muscle tissue indicates that these data differ in fish of the same genus, which are most significant in single indicators of Consistency.

Keywords: fish raw materials, sensory indicators, verbal description, hedonic assessment, lexical units, species difference, heat treatment, pair comparison

Acknowledgements: the authors express their sincere gratitude to the experts who participated in the sensory study for their qualified expertise.

Abstract. The main method of collecting materials was the questionnaire of amateur fishermen at different fishing points on the catch they had obtained, the time spent and the facilities used. Detailed information on amateur under-ice fishing along the coast of the Primorye subzone in January – March of 2025 was obtained. 102 fishing points were noted, 92 of them in Peter the Great Bay and 10 in northern Primorye. At different points, the number of possible days of under-ice fishing ranged from 8 till 76, and the number of amateur fishermen ranged from 2 till 100 people. The total amateur under-ice catch in the Primorye subzone amounted to 695453 kg: the main catch (96% of the biomass) was in Peter the Great Bay. The main objects were Pacific herring, Saffron cod, flounders and small-mouthed smelt. The peculiarities of the distribution and biological state of the main objects of winter amateur fishing are considered. Information about the volume of amateur fishing, which can be especially effective in the cold season from the ice, is necessary in the implementation of fishing regulation processes.

Keywords: Primorye subzone, amateur fisherman, under-ice amateur fishing, fishing point, fishing object, catch biomass

Abstract. It has been shown that the stocks of deep-sea fish can significantly increase the catches. The most suitable fishing method is the longline method, which allows for fishing in a wide range of depths. One of the limitations of this method is the high moisture content in the muscle tissue, which can reach up to 90%. However, the proteins are high-quality and capable of gel formation. The meat is also free from parasites. In the fishing area, it is possible to organize deep processing of raw materials, which will allow to expand the range of food products and obtain biologically valuable compounds and feed products from secondary raw materials.

Keywords: deep-sea fish, long-lining fishing, moisture content, complete proteins, absence of parasites, deep processing.

Abstract. Fleet allocation is the process of determining the optimal number and types of vessels sent to various fishing zones or trawl roads in order to maximize catch, profitability, or other performance criteria while taking into account limited resources. Mathematical optimization methods, in particular dynamic programming methods, are used to solve this multiparametric problem, which make it possible to formalize the decision-making process. The paper considers the result of optimizing the distribution of the mining fleet in conditions of limited fleet composition and distributed quotas for Commander squid fishing using the example of the South Kuril zone.

Abstract. Information is presented on the distribution, density of congregations, and size composition of starry flounder in the lagoon-type Lake Ptichye (southeast Sakhalin) from May to November and in February, based on the results of catches using nets and beach seines. It is shown that individuals up to 50 cm in length are observed in the lake, with the majority of the congregation (approximately 80 %) consisting of immature and newly maturing individuals up to 27 cm in length. The number of flounder in the lake is low, and while they are found everywhere, they concentrate at different depths in the northern and western parts of the lake.

Keywords: starry flounder, Lake Ptichye, distribution, density of aggregations, size composition

Acknowledgments: we express our sincere gratitude to all colleagues who participated in the collection and initial processing of materials, and to O.N. Mukhametova and V.S. Labay for the data provided on the seasonal variability of temperature and salinity in Lake Ptichye.

Abstract. In the waters of Russia, the long-nose sucker Catostomus catostomus rostratus is found only in the rivers of the East Siberian Sea basin: the Indigirka, Alazeya, Chukochya and Kolyma Rivers. In the Indigirka, it is distributed from the coastal sections of the delta channels to Oymyakon village (1624 km from the mouth); in the Kolyma, it is found throughout the basin. For fattening, it enters lakes, where it sometimes winters. It matures at 5+-7+ years and spawns in late May-June in the fast-flowing tributaries on sand-and-shingle bottom at the depth of 2-3 m. Its fecundity is 11,4-99,9 thousand eggs; the gonadosomatic index in July-August is 4,61 with fluctuations from 1,86 to 6,67 on average for all age groups in females, 5,95 and 3,13-9,15, respectively, in males. The food spectrum includes zooplankton organisms, shellfish, chironomid larvae, mayflies, stoneflies, caddis flies and dragonflies, water mites, mollusks, ants, and algae. Chironomid larvae prevail in food components. The food supply in the lower reaches of the Indigirka and Kolyma rivers is sufficient for the development and growth of the sucker populations. In the lower reaches of the Indigirka, the abundance and biomass of zooplankton were 9338 specimens/m³ and 0,067 mg/m³, and the abundance and biomass of benthos were 418 specimens/m2 and 18,52 m2. In the lower reaches of the Kolyma, the abundance and biomass of zooplankton were 10488 specimens/m³ and 3,59 mg/m³, and the abundance and biomass of benthos were 581 specimens/m2 and 21,67 g/m2. Net catches in the Indigirka contained sucker with the SL of 15,7-35,3 cm and weight 51-722 g. The age composition consisted of 6 groups from 1+ to 6+ years. In the lower reaches of the Kolyma, 11 age groups of the sucker with the SL of 15,7-45,3 cm and weight 45-1243 g were noted in the catches. The coefficients of fatness, F and K, vary within 1,13-1,33% and 0,71-0,86%, respectively, and increase with age. The sucker in the lower reaches of the river is inferior to that inhabiting the middle reaches and the Kolyma reservoir in terms of linear and weight growth. Decreased sucker growth in the lower reaches of the Kolyma, compared to the rest of its basin, is explained by the more intense food competition with numerous whitefish. There is no targeted fishery for the sucker in the Kolyma and Indigirka Rivers; the long-term annual average catch is 3,2 tons, which does not exceed 6,8% of the total development of the recommended catch volumes for all water bodies in Yakutia.

Abstract. In recent years, the Amur River has been in a period of low water content. Shallowing is associated with climatic and anthropogenic influences. This factor has a negative effect on aquatic organisms. In the course of the work, the parameters of the size and mass composition of the silver crucian carp of the Pirskaya and Pchelinaya channels (Amur River) in the period from 2023 to 2024 were analyzed. The characteristic of the ratio of length and mass, biological parameters of fish is given. It was found that in 2021 and 2022, individuals had a length of 7.5–26.9 cm and a weight of 9.2–574 g. In 2023, the average length was 16.37±0.15 cm, weight 157.40±0.92 g, in 2024 respectively – 18.72±0.15 cm and 222.54± 0.128 g. Understanding the size and mass indicators of the silver carp is the key to successful management of fish resources. These indicators include parameters such as body length and weight. Accurate data on size and mass characteristics make it possible not only to assess the state of the population, but also to predict its change, which is especially important for the protection and rational use of natural resources. The results of the work can be used in the planning and organization of work on the protection and exploitation of silver carp stocks in the Amur River.

Abstract. The article presents the results of a multifactorial system analysis of the distribution of Pacific herring catch quotas between users in the Far Eastern fishery basin. The analysis was carried out with respect to quotas granted to users for the purpose of industrial and (or) coastal fishing. The separate consideration of the North Okhotsk Sea subzone is not accidental, since the largest volume of the TAC of Pacific herring falls on this subzone – 80 %.

Abstract. This paper presents multi-year (2017-2024) data on the biology of fall chum salmon of the Gur River, Amur Basin. The materials were collected at the salmon fish farm. As a result of the research, the dynamics of size-mass, sex and age structure of chum salmon were determined. Chum salmon had minimum mean length in 2018 and 2020 (63±0,41 cm) and maximum in 2024 (68±0,28 cm). The mean weight varied from 2652±73,64 (2020) and 2704±65,43 g (2018) to 2913±79,74 g (2023). Mature fish belonged to three age groups. The share of the predominantly numerous individuals aged 4+ increased from 39 % in 2018 to 56 % in 2024. In 2017–2023, females were majority, in 2024, the share of females was 1,5 times less than males.

Abstract. The article discusses the use of a protein hydrolysate derived from crab processing waste as an ingredient in feed for rainbow trout (Oncorhynchus mykiss). An experiment was conducted at LLC "PROMKORM," where the results of feeding trout with traditional fishmeal-based feed were compared to those obtained when feeding them with a diet containing 5% protein hydrolysate from crab waste instead of an equivalent amount of fishmeal. The study employed biological analysis methods including measurements of key growth parameters such as absolute body weight gain and specific growth rate, along with determination of survival rates and morphophysiological characteristics of the trout. Parameters analyzed included changes in body length, head size, body mass, girth, internal organs like heart, spleen, and liver, visual examination of gastrointestinal tract fullness, and fat deposition levels. Results indicated a trend towards better growth performance and improved physiological condition among trout fed on diets supplemented with hydrolysate. Inclusion of hydrolysate into the feed resulted in increased body weight gain, specific growth rate, total body mass, dressed weight, zoological and commercial body lengths, Smith's body length measurement, although differences between groups were not statistically significant. No negative effects of the experimental hydrolysate on growth, survival or morphophysiological parameters were observed during the trial period. Morphophysiological studies revealed improvements in functional state of liver and spleen in fish receiving hydrolysate. Additionally, positive influence of hydrolysate on muscle tissue-to-fat ratio was noted. The article emphasizes the need for further research to assess potential benefits of increasing the proportion of protein hydrolysate in feeds to achieve greater efficacy.

Keywords: rainbow trout, closed water supply unit, protein hydrolysate of crab waste, absolute growth, specific growth rate, hepatosomatic index, somatic index of the heart and spleen

Abstract. The article provides a critical assessment of the technological modernization of the Russian fishing fleet. It demonstrates that despite the implementation of the investment quotas program, the industry retains a pronounced dualistic structure: a limited number of modern vessels coexists with an outdated fleet that dominates the fishery and accounts for the bulk of the catch. The key economic and institutional barriers leading to the low decommissioning rates of morally and physically obsolete vessels are identified: the high capital intensity of new construction, the rent-based model of access to aquatic bioresources, and the continued profitability of operating outdated vessels when harvesting mass commercial species. The conclusion is drawn about the fragmented nature of the Russian fishing fleet's modernization and the existence of systemic risks and barriers to the industry's long-term competitiveness.
