Relative Abundance of Planktonic Life in Relation to Water Quality Parameters in Non-polluted Zone of Deg Nullah

2003

Phytoplankton being primary producers in an aquatic habitat play a key role in the production of fishes in water body. Besides a number of other important factors their abundance depends upon various water quality parameters. This study was conducted to assess the relationship between water quality parameters of Deg Nullah and phytoplankton. Physical and chemical parameters studied during the present study were pH, Temperature, Turbidity, Total dissolved solids, Alkalinity, Carbon dioxide, Dissolved oxygen and Hardness. Phytoplankton community was also studied and their relative abundance was estimated using standard techniques. Finally multiple regression models of the predominant species were developed in relation with above mentioned water quality parameters to asses the effect of these parameters on phytoplankton and the overall ecology of Deg Nullah upstream.
