Abstract : The present study deals with the biological seasonal diversity and effect on ecosystem in zooplanktonic population in the Manth pond of Sunderpur area of Darbhanga, Bihar, India. The aim of investigation was to find out effect on ecosystem in zooplanktonic population due to seasonal diversity. The data collected in various months from March 2009- February 2010 revealed that the pond under study contains a much large number of zooplanktons: rotifers with 9 genera and 22 species, cladocera with 9 genera and 11 species and copepods with 6 genera and 6 species. With respect to seasonal variations and effect of ecosystem rotifers and cladocerans flourished well in warm weather months and copepods in cold weather months. The dominant zooplanktons were rotifers and shared 57.5% of the total zooplanktons whereas cladoceran shared 27.5% and copepods 15%.
