Ensuring food availability in such volumes that, without taking into account imports, the availability of foodstuffs is not lower than the world average consumption norms requires the expansion of the range of enterprises producing food products. Given the need to follow the Strategy for the Development of the Fishery Complex of the Russian Federation adopted in November 2019, covering the period until 2030, it should, in addition to measures including infrastructure reorganization, increasing catch and industrial production of fish products, increasing processed fish products range, it is necessary to consider the importance of fishery water bodies’ state and assess their fish productivity level. Under high anthropogenic impact on the water bodies of the Nizhnedonsky basin conditions, a hydrobiological situation is formed, when the increase in phytoplankton content indicates not an increase in fish productivity, but eutrophication high degree, while overgrowing of the water body is stimulated. Thus, the most popular fish productivity determination method, associated with food base level determination, will not give a sufficiently accurate water body’s fishery potential representation, as the increase in biomass level creates less favorable conditions for the vital activity of commercial fish species.
