Seasonal variation in the planktonic diversity of Tumaria reservoir of Kashipur Uttarakhand India

Abstract

Plankton are the microscopic plants and animals found in any aquatic ecosystem. Phytoplankton are microscopic plants while zooplankton are microscopic animals. The present investigation was carried out to find out the planktonic diversity of the Tumaria reservoir during January-December 2018. To fulfill the objectives of the present study, samples were collected from Tumaria reservoir on monthly basis. The samples were analysed for various physicochemical parameters (temperature, transparency, TDS, TS, pH, DO and chloride) and planktonic diversity. During the present study phytoplankton and zooplankton were identified under the microscope with the help of standard photographs following standard reference materials. During course of study phytoplankton was observed were Chlorophyceae (50%) > Bacillariophyceae (37%) > Cyanophyceae (13%) while zooplankton observed were Rotifera (40%) > Protozoa (34%) > Cladocera (23%) > Copepod (3%). It was also found that plankton diversity was found higher during the winter months followed by summer and minimum during the monsoon months. Planktonic diversity observed during study was found strongly correlated with temp (r= -0.56) and transparency (r=0.95).
