Abstract

The present investigation was carried out to assess the freshwater zooplankton diversity and their seasonal abundance in a selected freshwater ecosystem. The survey was carried out during the period from December 2014 to November 2015 to investigate the seasonal diversity of zooplankton in Kolavai Lake at three different sites. In all the three sites, four zooplankton families were found belonging to six species of Protozoan, nine species of Rotifers, five species of Copepoda and five species of Cladocera. Results indicated that the Kolavai Lake is more productive and has remarkable zooplankton diversity.

Keywords: Zooplankton, Rotifera, protozoan, cladocera, Copepoda.
