Abstract
The assessment of fisheries statistics data on the Azov-Black Sea fisheries regulation department during the period 2018-2024 was performed. The species structure of commercial fisheries in the Don River in conditions of anthropogenic transformation, related to construction of the cascade of hydroelectric power plants in the past period and the start of construction in 2018 of the new Bagaevsky hydroelectric power plant, was presented. During the research period the significant reduction in annual catch of all anadromous and semi-anadromous fish species was underlined. The most significant annual catch reduction was detected for sea roach. Significant changes in the species differentiation of the commercial fisheries was underlined, as a result of changes in the hydrological regime of the Don River. In recent years, there was a significant increases in annual catch of Prussian carp and «other species» group detected, which had previously been out of interest to the commercial fisheries.
