Phytoplanktonic Community Status in A Freshwater Shallow Lake of Ranchi

A study on the phytoplankton community, from Karamtoli pond at Ranchi, Jharkhand was undertaken during September 2009 to August 2010. The community showed a clear dominance of Chlorophyceae followed by Cyanophyceae and Bacillariophyceae. They showed summer peak in month of March and April and winter peak in September-October. 4 Species of Cyanophyceae, 5 species of Bacillariophyceae and 25 species of Chlorophyceae were recorded during the investigation from the study area. Scenedesmus and Closterium were dominant in most samples. The richness has been attributed to nutrient rich polluted environment of the tank.
