Abstract

The aim of the present study was to investigate the effect of water source on survival rate %, growth performance, feed utilization, fish yield, economic evaluation and production of Nile tilapia (Oreochromis niloticus) monosex reared in earthen ponds. Nine earthen ponds were used and divided into three categories of three earthen ponds each. The average size of each pond was approximately 5200m2, 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
