Abstract
Studies on food composition of two unexploited species, ruffe and gudgeon, were carried out in 1982 and 1984 in Włocławek Dam Reservoir. Diet of both species was essentially composed of Chironomidae larvae, Cladocera and Copepoda. Diet composition of ruffe and gudgeon suggests that the two species grazed mostly in shallow water, with ruffe penetrating the bottom, and gudgeon feeding in areas overgrown with submerged plants.
