Summary:In the zone of heated water discharge and at the control site of the Beloyarsk Reservoir, the phytoplankton was characterized by dominance of blue-green, green, and pyrrophyte algae, and the zooplankton, by the prevalence of crustaceans over rotifers. The study sites differed in the species and quantitative composition of the dominant complex, but the total abundance and biomass of the phytoplankton in the heated zone and the control site did not differ significantly. In Teplyi Bay, the zooplankton was inhibited, which was manifested in the decrease of its abundance and biomass by four and seven times, respectively, in comparison with the control. Radionuclide concentrations in the plankton of the cooling reservoir in the period between 1986 and 1988 were determined. It was found that radionuclide concentration in the plankton is higher in the zone of heated water discharge than beyond it.[PUBLICATION ABSTRACT]
