Abstract
A study was carried out to examine the seasonal diversity and density of zooplankton in Meghadrigedda reservoir during the study period from September 2014 to August 2015. Various physico-chemical parameters supporting the diversity and production of zooplankton were studied at three stations of the reservoir. A total of 46 species of zooplankton belonging to 16 species of rotifer in 7 families, 8 species of cladocera in 3 families, 6 species of copepod in 2 families, 3 species of ostracoda in one family, 3 species of protozoa in 2 families, 7 species of crustacea in 2 families, one species of mollusca and 2 species of fish larvae were identified. Species diversity (H-), evenness (E), species richness (S), Margalef’s richness index (R1) and Menhinik diversity index(d1) were calculated in the three seasons.
