Abstract | Untreated dairy food plant wastes were added to the fish ponds at a loading rate of 50 kg/ha/day. There were four treatments in the experimental design: treatment A (waste+ 2 mg N/l + 0.5 mg P/l), treatment B (waste+ 1 mg N/l + 0.25 mg P/l),treatment C (waste+ 0.5 mg N/l + 0.125 mg P/l), and treatment D (waste only). The nutrient sources were commercial fertilizers -- ammonium sulfate and superphosphate. Water quality parameters were determined regularly throughout the experiment period. Fishes were weighed individually in each pond every two weeks. After 14 weeks the fishes were harvested and gave extrapolated yields of 8,303.7; 7,849.2; 7,133.7; and 4,745.0 kg/ha/yr for treatments A, B, C, and D, respectively. Economic analysis showed treatment C to be the most profitable. |
