Abstract
A study was carried out to assess the diversity trend of zooplankton (ZP) in three freshwater habitats of Barak valley, Assam. Weekly collection of plankton samples have been done for three months from July 2015 to September 2015. Total 41 genera have been encountered during the study among which 32 genera found from Chatla haor (Site A), 29 genera found from Kar bhala wetland (Site B) and 26 genera found from NIT pond (Site C). The entire ZP community belongs to three major groups namely Cladocera, Copepoda and Rotifera. Beside these three groups there is one more group namely Ostracoda which comprises a small functional group in this particular region. In this present study the emphasis has given to the first three major groups.
