Zooplankton plays an important role in aquatic ecosystem. They are assisting the economically in fish culture. The zooplankton diversity in Narangi Sarangi Dam of Vaijapur Dist. Aurangabad Maharashtra, India was observed along with the physico-chemical characteristics for the period of from January, 2017 to December 2017. In this dm there is culture of food fishes viz., Catla catla, Labeo rohita and Cirrahuns mirigala, Ctinopharyangdon idella, Hipopthalamix molitrix, clarius batrachus, heteropnestus fossilis Tilapia mosambica, Cchanna Sp. Etc. During the study period, we collected 35 species from 12 genera (Rotifers- 06, Cladocerans- 03, Copapodes-2, and Ostracodes-1) of zooplanktons. The Rotifera was dominated accompanied by using Copepoda, Cladocera and Ostracoda species. Quantitative and qualitative analysis was made for distribution of the species. The physico-chemical parameters such as water temperature, pH, salinity, Total Dissolved Solid (TDS) and Dissolve Oxygen (DO) were analyzed throughout the study period. The connection among zooplankton and physico-chemical parameter together with the diversity indices had been calculated, because the productivity of zooplankton turned into unique, it could be continuously implemented for aquaculture.
