Indices of intestine filling, food composition and fatness have been analyzed. The results of the investigations showed that larvae of carp, bream and roach in Mingechaur reservoir consumed planktonic crustaceans (Copepoda, Cladocera) and filamentous algae, and mature fish of carp, bream and roach consumed crustaceans (Daphnia sp., Cyclops sp.) and vegetation. It has been found that compared with other seasons in the summer the feeding area of ​​carp, bream and roach expands and covers the entire western part of Mingachaur reservoir. ER -
