The study was undertaken to assess the physico-chemical conditions and record the zooplankton community at Sangave pond in Uttara Kannada district. A total of 34 zooplankton species were recorded. Cladocera was the dominating group in the pond with 14 species and highest abundance of 2302 individuals. Macrothrix goeldi was the most abundant species in this group represented with 228 individuals. Rotifera was represented with 10 species and 1776 individuals. Only three species of ostracods were recorded during 18 months study period. Dominance value of Ostracod was highest with 0.366 followed by Copepod with 0.1468 Rotifers with 0.1144 and the least dominance of 0.07314 was shown by Cladocera. Evenness was highest for Cladocers followed by Copepoda, Rotifera and least evenness value was of group Ostracoda Though the water body is located in the protected area the presence of eutrophic species like Brachinous calyciflorus, Lecane luna and fluctuations in the electric conductivity indicate that, there is a need for regular monitoring to conserve the water body from further deterioration.
