The present investigation has been carried out to study the status of primary productivity in relation to physiochemical parameters of the Dhanegaon reservoir of Osmanabad district, Maharashtra. The primary productivity was determined by estimating gross and net primary productivity. The experiment was conducted seasonal variation during the year of June 2004 to May 2005. The physiochemical parameters such as temperature, rainfall, pH, dissolved oxygen, total hardness and total alkalinity ranged from 20.60C-30.9C, Nil to 217 mm, 7.2-8.3, 7.2-12.6 mg/l, 75-170 mg/l and 108-147 mg/ respectively. The monthly variation of gross primary productivity (GPP) was 124-275 gC/m3/hr, Net primary productivity 0.87-0.182 gC/m3/hr and community respiration rate was 0.025-0.137 gC/m3/hr. The results indicated that during monsoon season, organic load is coming along with water in to the reservoir, but phytoplankton growth is minimum due to the heavy rain and flushing rate was high in the reservoir. The results indicate that Dhanegaon reservoir is more productive and suitable for aquacultural activity.
