The aim of this study was to investigate the diet of adult predatory fish (pikeperch, perch, pike, and catfish) that inhabit the Bovan reservoir and determine their impact on the ecological stability of the reservoir. The results showed that predators most often used planktivorous fish species in their diet, including bleak, roach, and perch. These species are dominant prey to predators, and at the same time important links in food chains. By feeding on planktivorous fish, predatory fish can contribute to the reduction of the eutrophication of the reservoir and keep this ecosystem stable.
