Abstract

Primary productivity study is important for the assessment of productivity of any aquatic systems. The present investigation is carried out to understand the status of primary productivity of Khaire reservoir of Raigad district. Analysis of primary productivity was done by using standard ‘Light and Dark bottle’ method of Boyd (1981) in every last week of the month for a period of two years (February 2014 – January 2016). In reservoir the values of GPP, NPP and CR were ranged from 0.38 to 2.81, 0.19 to 1.90 and 0.18 to 1.44 mg C L-1 hr-1 respectively. The results of the present study revealed that, the primary peak of productivity was observed during pre-monsoon season and the secondary peak was noticed during post-monsoon season. However, during the monsoon season low productivity values were recorded from the reservoir. From this it can be concluded that, Khaire reservoir is productive in nature.
