Abstract
Gammarids are a type of biological resources, the exploitation of which in Western Siberia has been successfully continuing for the second century. The catch of gammarids per unit area, the dynamics of biomass and their ratio in the lakes of the Kurgan region in the period 2000-2022 are considered. The trend of decline in commercial stocks of gammarids in recent years (2019-2022) compared with the period 2000-2015 is traced, the dynamics of catch is presented. The possibility of the impact of fishing on the reduction of stocks is discussed, it is proposed to change the procedure for submitting forecasts of the recommended catch of gammarids in inland waters in order to preserve and long-term operation of their stocks.
