The Study of Zooplankton Community in Unmanaged Pond Ecosystem in Bankura District, West Bengal and the Effect of Temperature, pH, Dissolved O2, Free CO2 Level in the Community

The aim of this study was to determine the diversity of zooplankton in a local pond ecosystem. Zooplankton plays a very important role in the food chain of pond ecosystem and its diversity is one of the determinant of shaping the food chain. Its diversity will ultimately decide the nature of the pond community. During our investigation in local pond, we have gathered various types of zooplanktons like Cyclops, Daphnia, Cypris , and Moina . Their number was influenced by the effect of pH (measured by digital pH meter), temperature (measured by thermometer), free CO 2 level (estimated by APHA method), and dissolved O 2 (estimated by Winkler’s method). The season wise variation of zooplankton in pond indicate the different environmental condition in water bodies.
