Biodiversity on the earth consist of innumerable of distinct biological species. The present paper reports on zooplankton diversity from the Thongjaolok stream, a partially subterranean stream located in the Bishnupur District at Manipur, North East India. The stream lies in the intersection of 24o 30″N and 93o 45″E. Due to the prime importance of zooplankton in fish culture, their role in recycling process of natural resources and degrade the waste materials for fish culture has to be investigated. Zooplankton diversity and physico-chemical parameters are important factors to evaluate the quality of a fresh water body. In order to study the status of Thongjaolok Stream, water samples and zooplankton samples were collected from Thongjaolok Stream during 2012-2014 subjected to analysis. A total of 31 species of zooplankton viz., Rotifera, Cladocera and Copepoda were recorded from the investigation. Among zooplankton, Rotifera were the dominant group represented by 22 species belonging to 6 genera and 5 families, cladocera represented by 9 species belonging to5 genera and 5 families and copepoda of 3 species; 3 genera and 2 families respectively. Physico chemical parameters were also studied in detail and correlated with the zooplankton occurrence and abundance.
