<p><span style="font-size:14px"><span style="font-family:Arial,Helvetica,sans-serif">During the present period of investigation extending from March, 2004 to February, 2005, 15 species of zooplankton belonging to five different taxa viz., Protozoa, Rotifera, Copepoda, Ostracoda and Cladocera were collected. Three of these taxa, Protozoa, Copepoda and Ostracoda were represented by single species while Rotifera by eight species and Cladocera by four species besides one larval form, the Nauplius. The number of plankton belonging to these taxa exhibited both quantitative and qualitative changes concuss with seasons and thus resulted in community changes during different seasons. The probable reasons (environment) that stand responsible and result in changes in community structure and individual population of each plankton have been discussed at length</span></span></p>
