Abstract
The long-toed crayfish Pontastacus leptodactylus Eschscholtz is one of the few invertebrates of freshwater reservoirs of the Altai Territory, representing a promising object of fishing. This paper provides an overview of changes in the state of cancer populations in commercial reservoirs of the Altai Territory in the period 2010-2021. The analysis of the dynamics of the main parameters reflecting the quantitative characteristics of cancer populations was carried out. The trend of decline in commercial stocks of cancer is traced, the dynamics of production (catch) of cancer by organized fishing is presented. The characteristic of the main causes of changes in commercial stocks of cancer, both natural and anthropogenic significance, is given.
