In spring and summer two peaks of development were found, characterized by average biomass values of 11.0-37.7 mg dm-3 and 8.1-44.7 mg dm-3, respectively. In general, diatoms prevailed, constituting from 68.3%-97.5% of phytoplankton biomass, while in periods when their numbers fell the dominants were plant flagellates. The seasonal dynamics of zooplankton development was also observed and at the same time its feeding pressure on the phytoplankton was then determined. The chief components of zooplankton were Bosmina coregoni and Daphnia cucullata.
