Abstract: Progressive increase of pollution at three sampling stations selected on river Chambal is indicated by the physico-chemical characteristics and zooplankton. A total of 25 genera of zooplankton are recorded from three stations with a maximum (22) at the least polluted station and the minimum (13) at highly polluted station. Keratella, Branchionus, Filinia, Daphnia, Cyclops and Cypridopsis were found tolerant to different physico-chemical conditions. The diversity index was minimum (1.0 to 2.7) at highly polluted station and maximum (3.1 to 4.9) at the least polluted station.

Keywords: Chambal river, physico-chemical factors, zooplankton, seasonal variation, diversity index
