<p> Investigations on Physico-Chemical features and Zooplankton species were conducted monthly using standard methods in two ponds namely Madikoppa and Benachi of Alnavar, Dharwad Tq./Dist., Karnataka between May 2012 to April 2013. All the physico-chemical parameters are within the range prescribed by ISO 10500-1991. Zooplanktons are heterotrophic planktonic animals floating in water. They serve as good indicators of changes in water quality. The different groups of zooplanktons have their own peak periods of density which is affected by local environmental conditions prevailing at that time. Rotifer species are more in number compared to other species in both the ponds.</p>
