The object of research is ichthyocenoses of inland fishery water bodies (their parts), mortality rates, conditions and organization of fishing. Research methods are generally accepted in ichthyology, hydrobiology and biostatistics. Current and retrospective data on the biological and fishery features of the formation of the ichthyofauna of the main fishery inland water bodies are presented. The state and dynamics of the population structure of the main commercial species in 2023-2024 are analyzed. The degree of industrial use of aquatic bioresources in the studied water bodies is quantitatively assessed. The size and age structure of fishing objects is analyzed as initial indicators for calculating the qualitative and quantitative parameters of the industrial load. Based on the analysis of the results of field studies, primary data (coefficients of industrial and natural mortality, replenishment, permissible elimination level, biomass-catch ratio) were determined for calculating stocks and permissible extraction volumes. Stock calculations were carried out and permissible extraction volumes were determined for the main inland fishery reservoirs in 2025. The total permissible extraction volume of aquatic bioresources for fish catch in the studied water bodies in 2025 is 22.15 thousand tons. The scientific justification was developed on the basis of scientific and analytical materials of the Institute of Fisheries of the National Academy of Agrarian Sciences, within the framework of the provision of services under the contract with DNU "IRGEMO" No. 1/2024/09 dated 06/26/2024 "Comprehensive assessment of the state of populations of the main exploited species of fish and invertebrates in inland water bodies of Ukraine and the Dnieper-Bug estuary system.
