Abstract

Availability of resources and competition would primarily determine the balance of individual species within the food web, which in turn influences the variety and proportions of the different organisms, with important implications for the overall functioning of the system. Zooplanktons are the smallest, acellular or metazoans in water bodies, ranging in size from 0.05 to 10 nm. The zooplanktons were represented by rotifers, cladocerons, copepods, ostracods, worms and larvae. Zooplanktons play a significant role in transferring energy in aquatic ecosystem as primary consumers and can be used as indicators of trophic phase of a water body. They also play an important role in the presence or absence of certain fish species and determines the population densities of zooplanktons. Most cladoceran species live in fresh water and other inland water bodies.Cladocerons are sufficiently large in size and can be identified easily so far the assessment of water pollution is concern. Cladocera (16.76%) dominated the zooplanktons population and were followed by copepod (15.49%); protozoan (15.06%); ostracods (13.28%); worms and larvae (11.52%). Seasonal distribution of cladocerans was in the order summer > winter > monsoon. Cladoceron were represented by fourteen species. Holopedium showed their dominance over all the cladocerons and their maximum number were reported at station I, III and IV. Similarly polyphemus were recorded highest at station II and III.
