Abstract: The structure of zooplankton in diet of common bream (Abramis brama) was analysed in the Hamry water supply reservoir during the period 2011-2014. Fish were captured by gill netting, beach seining and electrofishing in the littoral part of reservoir. Minimum twenty specimens of each size group were taken for analysis on each sampling occasion. Zooplankton in the diet of adult bream SL 210-315 mm and subadult SL 124-186 mm made recedent proportion. Juvenile bream (0+) SL 18-51 mm consumed zooplankton only. Daphnia galeata was dominant there. We found that decrease of cladoceran communities in the water supply reservoir might to cohere (related) with this specific feeding activity of bream's fry and the feeding competition of bream's and perch's fry in it's habitats.
