Functional classification and composition of phytoplankton of Liman Lake were studied between January 2002 and December 2003. A total of 109 taxa belonging to Bacillariophyta, Chlorophyta, Cyanophyta, Dinophyta, Xantophyta, Chrysophyta and Cryptophyta were identified. The succession during 2002 began with R-Strategists (with a high surface to volume ratio, including blue-green algae with filaments like Pseudanabaena limmetica Lemmermann). This group was followed by C-Strategists (small green algae characterised with fast nutrient absorption, assimilation and replication ratios). This group was again followed by R-Strategists and at last C-Strategists became dominant.
