Seasonal Variation of Phytoplankton Diversity in Anchepalya Lake, Bengaluru Urban, India

Seasonal dynamics of Phytoplankton populations were studied in Anchepalya Lake for a period of one year from March 2013 to February 2014 covering three seasons. Phytoplankton sampling, collection, quantitative and qualitative population was performed using APHA (2005) Standard methods. The counting of plankton was done by using Sedgwick Rafter counting cell and phytoplankton were identified by using the identification manual on limnology by Adoni (1985). A total of 88 genera of phytoplanktons were recorded. The diversity of Phytoplankton number is of increase as in the order of Chlorophyceae >Bacillariophyceae > Cyanophyceae > Eugleanophyceae. The present study revealed that the lake water is polluted with the direct entry of sewage and effluent discharge.
