Abstract

Eighteen earthen ponds (each pond 0.25 fed) rep- resenting six treatments with three replicates was carried out in this study. Control was fed diet containing 25% crude protein. Feed was applied six days per week at a rate of 7% for the first 2 weeks, then it was 5% for the next 2 weeks and finally at a rate of 3%, Oreochromis niloticus biomass. Treatment (A), poultry litter was added at a rate of 100 kg/pond weekly for the first 60 days followed by feed at a rate of 3% of fish biomass. Treatment (B), poultry litter was added at a rate of 50 kg/pond weekly plus feeding artificial diet at rate of 1.5% of tilapia biomass. Treatment (C) poultry litter was used at a rate of 50 kg/pond weekly. Treatment (D), cow manure was applied At a rate of 100kg/pond. Treatment €, urea and triple superphosphate was applied at a rate of 3.21 kg and 6.57 kg/pond. The experimental period was 5 months. Results showed that the highest water temperature was highest at August. Water temperature ranged between 26.1-29.9°C. The highest dissolved oxygen value was recorded for treatment E (5.2 mg/l), while the lowest was for treatment A (2.9 mg/l). The highest pH value was in-group E with an average of 9.3 during the study period. The total alkalinity increased in- group A to 424.9 mg/l than the other treatments. The average concentration of total phosphorus and orthophosphate increased to 1.90 and 0.83 mg/l respectively, in group A. The highest con- centration of chlorophyll"a" was recorded in group A (230M/I) and the lowest concentration
