Abstract: Studies on zooplankton population of river, Thamiraparani water, Kanyakumari District, Tamilnadu from February 2009 to January 2010 was made to assess the zooplankton diversity. The quantitative evaluation of the variation in river water showed high quantity of zooplankton throughout the study period and rotifers formed dominated group than other groups of organisms. Results revealed the presence of various zooplanktons at large numbers in all four selected stations. The indices such as Shannon – Wiener index, Simpson index, Margalef’s index, Menhinick index, Jaccard index, Sorensen index, Borger – Parker index of dominance were analyzed to assess zooplankton diversity in river water.
