Seasonal variation in primary productivity of two freshwater lakes of Aurangabad district, Maharashtra, India.

Abstract

Primary productivity gives information related to the amount of energy available to support bioactivities of system. The present study is aimed to know the status of primary productivity of two freshwater lakes namely, Mombatta and Kagzipura. It is determined by using standard ‘Light and Dark bottle’ method of Garden and Gran (1927) at an interval of 15 days in every month a period of two years (October 2008 to September 2010). Results indicate that Primary productivity of Kagzipura Lake is higher than Mombatta Lake. High productivity of Kagzipura Lake favors better growth of zooplanktons.
