Abstract

The selected sites of Gandak river near Sheetalpur ghat were studied for a period of one year from June 2013 to May 2014 for regular physico-chemical parameters and zooplankton community structure. The study was designed to estimate zooplankton abundance with seasonal repeated collections. The zooplankton community was composed of 08 species of Rotifera, 07 species of Cladocera, 02 species of Copepoda and 01 species of Ostracoda. These Crustaceans were dominant Class throughout the study period. The abundance of zooplankton in the pond follows a sequence as: Rotifera > Cladocera > Copepoda > Ostracoda. There changes in quantitative and qualitative community structure were found directly correlated with abiotic factors during study period.
