Abstract
Zooplanktons and macro invertebrate’s samples were collected monthly from two sampling stations at River Kapila,
Nanjangud, Karnataka State, India. Prior to sampling, temperature of surface water, pH, dissolved oxygen concentration etc
were evaluated. Zooplanktons were sampled using plankton net. The result revealed that zooplankton was made up of,
Rotifera (62.00%), Copepoda (12.00%), Cladocera (19.50%), Diptera (4.00%) and Nematoda (4.50%). The status of the
River could said to be eutrophic as indicated by the diversity of zooplankton.
