The document contains data on the current state of ichthyofauna as an important component of aquatic ecosystems and an integral part of the processes of formation of commercial fish production. The analysis of the dynamics of structural parameters of ichthyopopulations demonstrated that the total mortality rate of the main ichthyofauna species fluctuated within 0.38… 0.65, natural mortality within 0.16… 0.38, which corresponds to the level of fishery exploitation that does not exceed critical values. The efficiency of natural and artificial reproduction of ichthyofauna from the point of view of maintaining biodiversity and ensuring qualitative and quantitative characteristics of commercial catches has been analyzed. There is a possibility of increasing the fish productivity of reservoirs by 51.2… 160.0 kg/ha based on the stocking of 47 million juvenile fish. Theoretical bases and methodical approaches concerning regulation of the major forms of human impact have been substantiated.
