Abstract
The specific features of accumulation of fat, protein, mineral, and nitrogen-free extractive substances in the skeletal muscles of bream (Abramis brama L.) from areas of the Rybinsk reservoir subjected to different degrees of anthropogenic load have been studied. Data on the bream forage base and feeding in the reservoir are presented. It is shown that, in the areas of the Sheksninskii Reach with high food capacity located in the zone of long-term local anthropogenic pollution, the feeding intensity of bream decreases. This leads to a decrease in fish conditions and amount of fat and mineral substances in their muscle tissues when compared with specimens from conditionally clean stations in the Mologa and Volga reaches with high food capacity.
