WATER QUALITY IN RELATION TO PHYTOPLANKTON DIVERSITYOF GAUTAM KUND, DEHRADUN (UTTARAKHAND), INDIADhyal Singh, N. Kebosenti Chang and Ashu Chaudhary
This study deals with the study of water quality of Gautam Kund in relation to its phytoplankton diversityfrom December 2018 to April 2019 at two sites. A Total of 76 genera were identified belonging to 8 classes, 20orders and 40 families during the present study period. Class Chlorophyceae contributes maximum tophytoplankton population. Total density of phytoplankton was ranged in between 207.0 to 1615.67 Unit l-1.Three different ecological indices were applied to phytoplankton data show that water of Gautam Kundranges from moderately polluted to clean water. Principal component analysis was applied to explorerelationship between physico-chemical parameters and phytoplankton diversity.
