The article analyzes the Agreement between the Government of the Russian Federation and the Government of Japan on some issues of cooperation in the field of fishing for marine living Resources dated February 21, 1998, the Annex thereto, annual “Memoranda of Understanding” in the context of the full development of marine living resources by domestic fisheries in the marine area adjacent to the Kuril Archipelago. The article highlights the significant negative economic and political consequences in the event of the loss of at least part of this territory, which Japan has claimed, in particular, the Russian South Kuril Islands and the islands of the Lesser Kuril Ridge. Measures are proposed to protect Russian fisheries and territorial sovereignty in this strategic maritime area in modern changing conditions, taking into account the full development of marine living resources by the domestic fleet in the waters adjacent to the Kuril Archipelago.

The article presents the results of an analysis of the industrial development of the Commander squid in five fishing zones of the Far Eastern Fisheries basin in 2023. For each fishing zone, the period of commercial availability of the object, the period of maximum catch is allocated and the average daily catches for mining vessels are calculated.

The Pacific perch is the most numerous species of the genus Sebastes. The extensive range of the beaked perch and the peculiarities of the distribution of high-density concentrations in limited areas make it very difficult to assess its stock, and intensive fishing leads to the undermining of stocks for a long period. The current state of the stocks of beaked perch in the EEZ of Russia is considered and retrospective data on the fishing of the species in the main areas of world fishing are presented. Based on the expedition materials collected in 2021-2022 in the Bering Sea, the age was determined and the growth rate of the beaked perch was considered. A brief overview of the size composition of the perch herd of the East Kamchatka and North Kuril fishing zones is also given based on materials collected in February – April 2024. The age determination technique is described in detail and, based on the age definitions of fish of different lengths, a size and age key is calculated for practical use.

The article presents the results of the development of the West Bering Sea cod and cod of the Chukchi zone from 2020 to 2023, assesses the problems of development and identifies possible solutions. The dynamics of changes in the volumes of ODE and catch, the composition of users of this resource by types of production quotas in the West Bering Sea and Chukchi zones are studied, the effectiveness of their volumes from 2020 to 2023 is estimated.

The article provides materials on roach catches over the past 120 years. The relationship between catches and provisions of the Fishing Rules since 1937 is shown. The analysis of the impact of changes in the Caspian Sea level over the past 65 years on the state of the forage base and roach catches in the Northern Caspian Sea is made. A biological justification is provided on the basis of which proposals are formulated for the conservation and increase of roach stocks in the Volga-Caspian fishing area.

In 2024, for the first time, such a large-scale and detailed sonar survey of Baikal omul reserves was conducted within the entire water area of the lake, which made it possible to assess omul reserves at 4 polygons (fishing areas), coastal and deep-water areas. On an area of 2.8 million hectares, the total number of omul was 37 million, and the biomass was 8.6 thousand tons. The main biomass in 2024 are concentrated in the Selenginsky shallow water and account for 51% of the recorded stock for the entire Baikal area. The biomass of omul in the Barguzin Bay has increased significantly, and quantitative growth of omul in the Small Sea has also been observed. As in previous years, high concentrations were recorded in the waters of Northern Baikal. Compared with previous observations, there was a spatial redistribution of omul, and the highest concentrations were recorded not near Nizhneangarsk, but south of Severobaikalsk. An exceptionally high abundance generation born in 2020, comparable to the 90s, has been noted, which will have a positive impact on the restoration of omul biomass in the coming years. According to preliminary mathematical modeling data, provided that the number of recruitment of the fishable stock is at the level of 2021-2024 (generation 2019-2022 years of birth), a rapid increase in stocks of omul is predicted in the coming years, which creates possible opening dates of the fishery and recommended catch volumes. The 2025-2026 research will clarify the possible timing of the opening of the fishery and the recommended catch volumes.

Based on ichthyological materials collected in 2018-2022 in the northern part of the Agrakhan Bay of the Caspian Sea, the biological indicators of vimba, kutum, and walleye are considered. It is shown that in the years under review, the average values of length, weight, age decreased in kutum, and the condition of the groupings of this species should probably be recognized as unfavorable. The biological indicators of the vimba tended to increase, the condition of the grouping of this species does not cause concern. The biological indicators of walleye, despite the depression in numbers, increased slightly.

The article examines the history of the formation of caviar and commercial sturgeon farming in Russia (USSR) and the current state of this sub-sector of fisheries. It is noted that, despite the short period of existence and difficulties of growth, caviar and commercial sturgeon farming in Russia was established and continues to develop successfully. Its peculiarity is the transition mainly to a rational and humane lifetime method of obtaining raw caviar. The main problems of the development of the domestic caviar market are competition with imported products and excessive regulation by the state. The ways of solving these problems and expanding the raw material base of production are proposed.

Mathematical assessment of physiological indicators of tilapia vitality. Research to identify the most viable fish using functional loading. Phenol was used as a stress factor. Experimental data on the calculation of the number of surviving individuals at certain points in time, depending on blood parameters, were mathematically processed using the survival comparison method. The use of blood indices is necessary as a means of diagnosis and prognosis in pathological processes in order to achieve objective results in fish farming practice. As one of the indicators of the adaptive capabilities of cultured fish, the authors propose to use a blood score on a five-point scale.

To build fishing gear, nodal sections with different orientations of the del are used: T0 (standard mesh arrangement); T90 and T45 (T0 rotated by 90° and 45° respectively). The paper discusses the use of this method to determine the hydrodynamic properties of objects with different mesh rotations. A schematization of the canvas was carried out to develop a mathematical model based on the Navier-Stokes equations. The calculation was performed on a regular computational grid using an implicit finite-difference scheme using the methods of coordinate splitting, linearization of nonlinear equations with subsequent correction of nonlinear coefficients, as well as rhenium of tridiagonal systems by the sweep method. The paper presents the results of numerical experiments in the form of visualization of pressure on the surface of various mesh structures at different angles of attack.
