Characterization of phytoplankton in the Sulejów Reservoir in 1991-1993

Abstract

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.Zadanie pt.
