Abstract: Zooplanktons are the heterotrophic, floating plankton that range from microscopic to large species. The zooplanktonic communities occupy an important place in food web of an aquatic ecosystem. It is also an integral part of the lentic aquatic ecosystem and significantly contributes in the productivity of a fresh water ecosystem. The diversity of zooplanktons is highly influenced by variation in season as well as physico-chemical parameters. The present paper deals with the zooplanktonic communities present in the water of river Karamnasa at Buxar, Bihar. For this purpose, the physicochemical parameters of river Karamnasa were studied and the zooplanktonic samples were collected from the different sampling sites from the period January 2018 to December 2018. Quantitative analysis was done by dropping method of APHA (2005)1. The result of this finding concludes that 12 species of zooplanktonic communities have been found in the water of river Karamnasa. All the species belong to four major groups as Rotifera, Cladocera, Copepoda and Ostracoda. Cladocera was most dominant group while Ostracoda constitute the smallest group of zooplankton during the whole period of investigation.
