摘要：The present study discusses the Primary Productivity of lotic and lentic water. The Light and Dark bottle method are used to measure primary production. The primary productivity helps to determine the trophic level of various aquatic systems. The primary productivity of any aquatic ecosystem depends on the planktonic biodiversity. Estimation of primary productivity of a water body helps to assess its carrying capacity for a biological population which sustain in it by the respiration. It is the most important of all biological phenomena on which the entire diverse life depends directly or indirectly. The present study was done to estimate the primary productivity of lotic water and lentic water. The results showed that in Beas River, the NPP, GPP, Respiration and Gross Photosynthesis were 31.25 mgL m–1h–1, 125 mgL m–1h–1, 112.50 mgL m–1h–1, and 0.40 mgL m–1h–1, respectively. Whereas, in the Ravi River these were 31.25 mgL m–1h–1 , 52.08 mgL m–1h–1 , 25.01 mgL m–1 h–1, 0.166 mgL m–1h–1, respectively. In case of another two ponds, the NPP, GPP, Respiration and Gross Photosynthesis were 50 mgL m–1h–1, 112.50 mgL m–1h–1, 75 mgL m–1h–1, 0.36 mgL m–1h–1 and 62.50 mgL m–1h–1, 114.61 mgL m–1h–1, 62.51 mgL m–1h–1, 0.36 mgL m–1h–1, respectively. In the two rivers, it was found that NPP level was in same but GPP and respiration rate were higher in the Beas River water. It shows that the Beas River has the highest rate of photosynthesis as there is the highest number of primary producers. Both the pond has the high value of NPP than river water. However, the highest value of NPP was recorded in lentic water and lowest NPP was recorded in lotic water. The main focus of the study was to estimate the Net Primary Productivity for analyzing the water quality and find the pollution level due to increased anthropogenic activities.
