Primary Productivity Studies in some Freshwater Reservoirs of Sangli District, Maharashtra

Primary productivity of water body gives a quantitative information about the amount of energy available to support the bioactivity of system. The aquatic bodies namely Bhambarde, Lengre and Atpadi were selected for primary productivity studies. Experiments were carried out from August 2006 to July 2007. The gross primary productivity of Bhambarde reservoir varied from 1.49 to 5.14 O₂ mg/L/h. At Lengre reservoir, GPP value ranged from 1.56 to 5.28 O₂ mg/L/h. Atpadi reservoir showed GPP value varying from 1.31 to 4.98 O₂ mg/L/h.
