In 1991-1993 phytoplankton was investigated in the Sulejów
Reservoir. In spring and autumn two peaks and additionally in summer 1992 one
peak of development were noted, characterized by average biomass values of 8.1 to
33.4 mg dm^-3. In general, diatoms prevailed, mainly Stephanodiscus hantzschii Grun.
and Melosira granulta (Ehr.). When their numbers fell the dominants were plant
flagellates. The blue-green algae (Cyanophyta) were high only in several months in
summer and early autumn, their chief components being Microcystis aeruginosa
Kutz. and Aphanisomenon flos-aquae (L.) Ralfs. The seasonal dynamics of zooplankton
development was also observed and at the some time its feeding pressure on the
phytoplankton was the determined.
