PT Journal AU Hasler, P Poulickova, A Lysakova, M TI The survival and vitality of cyanobacteria and algae in fishpond bottom sediments SO Czech Phycology PY 2004 BP 133 EP 144 VL 4 IS 1 AB The extraction of sediment cores took place in January 2003 during total ice covering of the investigated fishpond. 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 KOMAREK during last 5 years. Cyanobacteria occurred sporadically in sediments. ER
