Abstract

Zooplankton occupies a central place between autotrophic and heterotrophic and constitutes an important link in the food chain of a freshwater ecosystem. The presence and frequency of zooplankton are always influenced by physical-chemical factors and nutrient content in the water. In the present study, diversity, seasonal fluctuations and correlation coefficients of zooplankton were determined from July 2008 to June 2009 at Harsool Dam in Aurangabad (M.S.), India. A total of 25 species of zooplankton were recorded belonging to order Cladoceran (8 species), Copepoda (5 species), Rotifera (10 species), and Ostracoda (2 species). In this study 10,860 zooplankton (organisms/liter) with a maximum percentage of 31.67% Cladocera, 33.88% Copepoda, 29.65% Rotifera and 4.78% Ostracoda were observed in the Harsool Dam during the study period. Summer showed a longer food chain than other seasons. According to the Shannon Index, the values showed that the waters of the Harsool Dam were contaminated. Homogeneity indices indicated that all species are equally common in a sample.
