Planktonic Biomass Conversion Efficiency of Major Carps Integrated Farming Systems

Muhammad Hassan and Muhammad Javed

The response of different levels of nitrogen from broiler droppings towards planktonic productivity and fish yield increments has been studied. There existed significant differences among six treatments, i.e. 0.10, 0.13, 0.16, 0.19, 0.22 g N/100 g fish levels and control (without additive) for both increase in fish yield and planktonic productivity of ponds. However, the treatment responses towards planktonic biomass conversion efficiency of ponds were statistically non-significant. Planktonic productivity of ponds under all the five fertilization regimes had positively significant regression on fish yield increments. Nitrogen conversion ratio in ponds had positively significant correlation with planktonic biomass conversion efficiency. Increase in fish yield, planktonic productivity and nitrogen conversion ratio showed positively significant regression on water temperature.
