The African Catfish (Clarias gariepinus, Teugels) were reared at three different stocking densities in bamboo-net cages to evaluate the effects of stocking density on growth, survival rate and food conversion ratio. Three hundred (300) fish with a total weight of 1.8 Kg were stocked at 25, 50 and 75 fish/m 3 cage with a mean weight of 5.6±0.23 g, 5.9±0.23 g and 6.3±0.23 g/m 3 respectively. The growth trial lasted for 150 days (May 2009 to October 2009). Twenty percent (20%) of the total biomass of the fish in each cage was weighed monthly and the bulk weights were calculated. Mortalities were recorded monthly. The final mean weights (±SE) of the fish stocked at densities of 25, 50 and 75 fish/m 3 cage were 828.0±1.83 g, 774.0±20.18 g and 693.0±34.20 g. The corresponding mean values of Specific Growth Rate were 3.33, 3.25 and 3.43. Temperatures ranged between 24.5 0 C-32.6 0 C while salinity ranged between 24-95ppm. The Feed Conversion Ratio (FCR) was 4.99, 4.73, and 3.43, and cumulative survival rates were calculated as 99.84, 99.66 and 99.50% respectively. The results revealed that stocking density had a significant (P> 0.05) effect on growth and survival rates of Clarias gariepinus. Fish held at the highest stocking density exhibited the lowest growth and survival rate. Cages with 50fish/m 3 stocking density had the best production with total final weight (38.67 Kg) and profit index (3.27) compared to other treatments (P> 0.05).
