Nine earthen ponds were used and divided into three categories of three earthen ponds each. The average size of each pond was approximately 5200m 2 , 6000 monosex all male Nile tilapia were used in each pond and were stocked for 192 days. The fingerlings average weight was 4.38±0.03g/ fish, the fish were fed using a floating feed 25% crude protein, and were fed at a daily rate of 3% of their body weight. Results showed that body weight was increased significantly (P<0.05) with well water to 472.33g/fish. While were 354.17 and 320.17g/fish for fresh and agricultural drainage water, respectively. Specific Growth Rates (SGR%) increased with well water compared ...
