Zooplankton is free swimming microscopic animal. They play an important role as a food for aquatic fauna. We may even consider them as the most numerous animals on earth. They forms a remarkable bioindicator for water pollution. In the present piece of work an attempt has been made to investigate the distribution of Zooplankton in Vena river district Nagpur. Study of Zooplanktons in various seasons has been carried out at a 4 sites of Vena river. Samples were collected in all the month during year 2013. The Zooplankton population is represented by four different groups in winter season viz. Protozoa, Copepoda, Cladocera and Rotifera. In the present investigation during winter season maximum density of Zooplankton is in the month of January. However Zooplanktons minimum density was recorded in the month of October due to the domestic sewage, industrial sewage, concentration of water and rise in temperature.
