Spatial Planktonic-diversity in Gandak floodplains of Gopalganj, Bihar

The floodplains contribute significantly in maintaining regional freshwater biodiversity. The planktonic community of a floodplain is strongly affected by the spatial changes in abundance and diversity of phytoplankton and zooplankton. The objectives of this study were to establish the diversity and distribution of planktons in the Gandak floodplains of Gopalganj district in Bihar. During the biannual seasonal analysis of this pond between year 2019-21, the average values for phytoplankton density and zooplankton density were observed respectively. The result suggested good planktonic diversity in the floodplain, which is suitable and adequate for rich fish community in the floodplains.
