In the present study 16 sampling stations were selected in River Damodar at Jharia and Raniganj. Primary productivity of water was determined by light and dark bottle method. Seasonal variations of gross primary productivity (GPP) net primary productivity (NPP) were determined. Spatial variations in productivity level and dissimilarity coefficient were determined by using chord distance for different seasons. Regression model was determined to estimate role of major phytoplankton groups for the production. Cluster analysis was done for placing similar or statistically related stations into one group.

Abstract


In the present study 16 sampling stations were selected in River Damodar at Jharia and Raniganj. Primary productivity of water was determined by light and dark bottle method. Seasonal variations of gross primary productivity (GPP) net primary productivity (NPP) were determined. Spatial variations in productivity level and dissimilarity coefficient were determined by using chord distance for different seasons. Regression model was determined to estimate role of major phytoplankton groups for the production. Cluster analysis was done for placing similar or statistically related stations into one group.
