Seasonal dynamics of the feeding of A. gueldenstaedti and A. Stellatus was studied in Karkinitskii Bay of the Black Sea. More accurate data were obtained on the nutrition spectrum of the fish. It was found that Mytilus galloprovincialis was the principal component of A. gueldenstaedti diet. Sevryuga fed for the most part on Polycheta: in the summer on Melinna palmata and in the spring on Terebellides stroemi. The study of the state of benthic communities in the bay showed that only 7% of the production of food benthos were used by the fish which makes it possible to increase its resources at the account of intensified artificial reproduction.
