SEASONAL VARIATION AND DIVERSITY OF ZOOPLANKTONS IN RELATION TO SEASONAL VARIATION OF PHYSICOCHEMICAL PARAMETERS OF WATER BODY IN PURBA BARDHAMAN, WEST BENGAL

Zooplanktons, also regarded as heterotrophic planktons, serve as integral part of food chain. This paper depicts the diversity, seasonal variations of zooplanktons in relation to the seasonal variations of physicochemical parameters of water body of Purba Bardhaman, West Bengal. The study was carried out for six months (November, 2018 to April, 2019). Physicochemical parameters include study of air temperature, water temperature, pH, dissolve oxygen, hardness, free carbon di oxide, alkalinity, phosphate, calcium chloride. Zooplanktons, obtained during this study include protozoa, rotifer, copepod, cladocera, ostracoda and crustacean larva.
