Aquatic systems play important role in landscapes as they are habitats for different biodiversity (lower to higher level organisms) which has an important role in food chain or food webs. These zooplankton are serving as a food for other higher organisms. Zooplankton transfer the energy from primary level to higher level. A total 31 species of zooplankton notice in the Nandashwer dam protozoa (10 genera), Cladocera (10 genera), Copepoda (3 genera), Ostracoda (3 genera) and Rotifera (7 genera). Dominant zooplankton were Cladoceran > Rotifera > Protozoa > Copepoda > Ostracoda.
