Sediment cores were cut into 3-cm-thick layers. Sediment samples were cultured and vitality of cyanobateria and algae was studied. Altogether, we identified 49 species of cyanobacteria and algae. Green algae were the most frequent and vital group. Fishpond phytoplankton was dominated by Planktothrix agardhii (GOMONT) ANAGNOSTIDIS et KOMÁREK during last 5 years. Cyanobacteria occurred sporadically in sediments.
