Abstract

The present study of the seasonal abundance of some plankton in the river Ganga with particular reference to water pollution is observed seasonally during November 2016 to September 2017 from three stations of Doriganj, Chapra, Bihar. According to the present study, 3 groups of phytoplankton and 4 groups of zooplankton were observed, their percentage in different seasons were, Chlorophyceae ( summer– 31.82%, winter- 45.45%, monsoon- 22.73% ), Bacillariophyceae ( S- 30.86%, W- 43.21%, M- 25.93% ), Myxophyceae ( S- 30%, W- 46.66%, M- 23.33% ), Rotifers ( S- 17.14%, W- 74.29%, M- 8.57% ), Copepod ( S- 18.6%, W- 74.42%, M- 6.98% ), Cladocera ( W- 88.06%, M- 11.94% ) and Ostracopoda     ( S- 40.43%, W- 55.32% and M- 4.26%). The phytoplankton and zooplankton were observed maximum in winter season and minimum in monsoon season. During the present study, relevant correlation showed total phytoplankton had a highly significant relationship with TDS (-0.83), DO (0.92), and temperature (-0.93). Zooplankton had also highly significant relationship with TDS (-0.93), DO (0.98) and temperature (-0.98).
