The increase of the predation rate of fish and the increase of the consumed biomass were observed in big crustacean species (Daphnia cucullata, Eudiaptomus graciloides and Diaphanosoma brachyurum), the biomass and production of which decreased in successive years. ; Strony 553-562 ; 24 cm ; Bibliografia na stronie 561 ; Streszczenie w języku polskim ; The utilization by older age-groups of fish (tench, carp, crucian carp and bream) of the biomass and production of zooplankton in the years 1967-1969, was assessed.
