Zooplankton is an integral component of aquatic ecosystem and comprises of microscopic animal life that passively float or swim freely. In the present study the selected shanigaram reservoir for the purpose of the study. Zooplanktons are the smallest metazoans in all water bodies, ranging in size from about 0.05 to 10 mm. They provide food for many spices of fish and are therefore, vital role in the food web of ponds. A total of 16 Zooplankton taxa were observed in the lake and found dissimilarities in three seasons. During the study period the total numbers of 16 species are identified from the selected reservoir during the study period. Rotifer, Cladocera, copepod and Ostracoda. Seven number of Rotifer sp., Four number of Cladocera sps, three number of copepod sp. and Two number of Ostracoda sp. in the selected stations. In Rotifers were higher in pre-monsoon season Cladocera during monsoon season and Copepods in post-monsoon season were dominant taxa. This was the systematic survey on the fish diversity of this lake It is proposed that the scientific information on icthyofaunal diversity and distribution status will surely help in serving the future purposes of sustainable exploration and concurrent conservation of fish resources. This was the systematic survey on the fish diversity of the lake.
