Comparative analysis of fisheries and biological characteristics of bream (Abramis brama) in Saratov and Volgograd reservoirs

Based on the results of ichthyological surveys and industrial catch data, a comparative analysis of the commercial biological characteristics of bream in the Saratov and Volgograd reservoirs was carried out. The material was the results of expeditionary research by employees of the Saratov branch of the VNIRO. With the existing fishery, bream stocks are in a stable condition. The volumes of commercial stocks and catches of the species in question in the Volgograd Reservoir are higher than in the Saratov Reservoir. Despite differences in fishing intensity and characteristics of reservoirs, the size and weight indicators of the species are similar.
