Aquatic organisms, especially plankton from the most sensitive component of the ecosystem and signal environment disturbances. Apart from primary production, phytoplankton plays an important role in the energy transfer. This paper deals with the analysis of plankton composition for two years of Varaha reservoir in Kalyanapulova. Sampling data was obtained from February to November 2010-2012. Phytoplankton was represented with 3 groups which Chlorophyceae was dominant with 10 species followed by Bacillariophyceae (2), Cyanophyceae (3) a total of 15 species of phytoplankton were recorded with similar distribution. The study helps in better understanding for the management of the Varaha reservoir for intensive fish culture.
