Phytoplanktonology of Chhinda dam at Simdega, Jharkhand

Keeping in view status evaluation as the corner stone of environmental management, present investigation has been aimed at study the present status of the phytoplankton dynamics, which constitute the main fraction of food of the aquatic fauna, of Chhinda dam water at Simdega, Jharkhand. Seasonal fluctuation, percentage composition and yearly averages were computed taking monthly observation data from June, 2008 to May, 2010 in relation to abiotic spectrum of the dam water. Simple correlation as well as multiple correlation analysis was computed. Coefficient of determination (R2) in the present investigation was computed as 0.948 which indicated that 94.8% fluctuation in phytoplankton standing crop of the dam was dependent on the physico-chemical regime of the dam water considered for the present investigation and 5.2% to other factors which were not taken into account in the investigation understudy.
