Quantitative and qualitative enumeration of phytoplankton community in relation to Physico-Chemical Factors in Tumbadi Lake of Koratagere, Karnataka

The present studies were made on the enumeration of phytoplankton with respect to physico-chemical parameters in Tumbadi Lake Koratagere state Karnataka. Composite water samples collected from designated stations at surface level during summer, winter and rainy seasons January 2020 December 2020. Total 49 species identified under 31 genera belonging 5 different taxonomic groups seasonal maxima summer.
