The limnological environment of the pond was conductive for fish rearing under all the treatments except for 0.22 g N level and the control. Increasing the nitrogen level beyond 0.16 g N showed a significant rise in the potassium contents of water and hence zooplankton productivity was affected negatively under both 0.19 and 0.22 g N level. The response of treatments towards the release of nutrients like nitrates and the phosphates promoted both the phyto and zooplankton productivities and hence exerted positively significatnt regression of phosphates in 0.10 g N level. Among the water quality variables, water temperature appears to be the most critical parameter influencing the productivities of both phyto-and zooplankton significantly.
