This study analysed diversity and ecology of Zooplankton and also Hydrophytes of wetlands, of Paschim Medinipur, West Bengal, India. Zooplankton samples collected (April to December, 2014-2016) from site-I (Panskura), site-II (Gokulpur), site-III (Jakpur) of this tropical wetlands revealed a fairly rich Zooplankton fauna and hydrophytes from at this entire study site. This survey yielded 37 species of Zooplankton (Rotifera, Copepoda and Cladocera) and 7 species of hydrophytes of Paschim Medinipur wetlands. High species diversity and low densities of majority of species are hypothesized to fine niche portioning amongst different species in combination with high micro and macro scale heterogeneity.
