Abstract
The present attempt is made to assess the various diversity indices of zooplankton in Hasanparthy Lake during the year 2022-23. A Heron-tranter plankton collecting net was used to collect the zooplankton from the selected lake. The collected plankton were preserved at 4% formalin for further quantitative estimation. A total of sixteen species of zooplankton were observed in this study. The highest number of species are Rotifera group and the lowest number are Ostracoda group. The Shannon _H and Simpson-1_D and Evenness diversity indices were calculated in the present study and the highest values of Shannon _H values were noticed in the Rotifera group (1.821) and followed by Copepoda (1.750), Cladocera (1.093), and the Ostracoda (0.683). The Simpson-1_D values were highest in Ostracoda group (0.803) and followed by Copepoda (0.778), Cladocera (0.337) and Rotifera (0.274). The abundance of zooplankton in the selected lake that in a non-polluted state and supports to trophic level.
