Abstract– Important fin-fish and shell-fish cultures are economically supported by Zooplankton. They play a major role in transferring energy between phytoplankton and fishes. Zooplankton abundance and species diversity of Bishanpur were studied from March, 2020 to February, 2021 on monthly basis. The principal aim was to get information about the overall zooplankton diversity of this swamp. Zooplankton samples were collected using zooplankton net and preserved in 5% formaldehyde solution on the spot, then brought to the laboratory for further analysis. 18 species of zooplankton, belongs to four different classes were recorded (Rotifera, Cladocera, Copepoda and Ostracoda) in which Rotifera was the most dominant class followed by the Cladocera, Copepoda, and Ostracoda. From total 18 species, 8 belonged to Rotifera, 5 from Cladocera, 2 from Copepoda, and 2 from Ostracoda. Shannon – Weaver index was employed to analyze the species diversity.

Key words: Bishanpur Swamp, Cladocera, Copepoda, Ostracoda, Rotifera, Shannon – Weaver index, Zooplankton
