Abstract

A year long study (2002-2003) was conducted in the Kalyani fish farm (P1) - a scientifically managed fish farm and Kalyani lake (P2) - a weed infested natural water body, in the heart of
Kalyani city, West Bengal, to draw an interrelationship between the primary productivity and nutrients in water as well as soil at different temperature regimes. The study recorded high primary
productivity in P1 corresponding with the high nutrients in water (NO3-N and PO4-P) and soil (available nitrogen and available phosphorus). A moderate range of primary productivity was
recorded in P2 in accordance with the moderate ranges of nutrients in water and soil. No significant variation in temperature was recorded between the two water bodies. A strong influence of temperature was observed both on the primary productivity and availability of nutrients. A
significant correlation (P<0.05) was recorded between the net primary productivity (NPP) and the available nitrogen and phosphorus of soil. However, no significant correlation (P>0.05) was observed between the NPP and the exchangeable potassium of soil in both the water bodies
