Abstract : Zooplankton are the primary consumer of the aquatic food chain. It has been extensively studied in different water bodies of our country. Present study is related to zooplankton community of Sahasmal Wetland of Koshi River in Araria District, of North Bihar. The role of Zooplankton in the aquatic food chain is very important as it occupies the place of primary consumer and at the same time as secondary producer. The productivity of zooplankton will reflect the status of the aquatic system. In the present study of Sahasmal Wetland Araria, 11 species registered in Cladocera belong to 10 generations, 7 families, and 2 orders. Along with zooplankton, there were nematodes, aquatic insects and mosquito larvae. Among the phytoplankton, 12 species were registered with Bacillariophyceae, Chlorophyceae and Dinophyceae. Overall phytoplankton and rotifers contributed to the higher composition followed by copepods, cladocerans, and protists.
