Abstract

The primary productivity of a particular water body gives quantitative information about the amount of energy available to support bioactivity of the system. At Kotwal reservoir the mean of gross primary productivity was minimum 68.94 mg Cm3 per hour and maximum 153.51 mg Cm3 per hour with an average of 111.9 4.19 mg Cm3 per hour, The net primary productivity was 41.7 mg Cm3 per hour to 100.30 mg Cm3 per hour with an average of 66.98 2.75 mg Cm3 per hour, The respiration rate was found 27.24 mg Cm3 per hour to 65.25 mg Cm3per hourwith an average of 44.92 2.02 mg Cm3 per hour during study period from June, 2008 to May, 2010. The ratio of NP: GP, NP: RR and RR% were estimated 0.60, 1.53, 2.53 and 40.11% respectively.
