Abstract

The paper provides a brief analysis of the retrospective and current state of industrial fishing of Lake Tsatsa, as well as the results of studies of the state of the commercial fish fauna and its food supply. The results obtained made it possible to develop the most optimal strategy for the fishery use of fish stocks, which is based on the maximum possible harvesting of the slow-growing population of bream, the irruption of which causes a further deterioration in feeding conditions for traditional commercial fish - carp and crucian carp. They are more in demand among the population and, accordingly, more profitable in the fishery, which is the first direction of the proposed strategy. The second direction of the strategy is the directed formation of the ichthyofauna with the predominance of the biomass of the most commercially valuable species - herbivorous fish, which is ensured by the existing significant reserves of phytoplanton and macrophytes. The introduction of herbivorous fish juvenile as objects of pasturable fish culture will increase fish productivity and produce annually from 20 to 55 tons of valuable fish products.
