Abstract: Experiments were conducted in aquaria tanks (62.5x29.5x30 cm) for a period of 12 weeks to investigate the effect of stocking density on the growth and survival of Clarias gariepinus fingerlings. The fingerlings (average weight of 0.60 g) were stocked in densities of 5, 10 and 15 fish per tank in duplicate and were fed with a diet containing 35% crude protein diet at 5% body weight twice daily. Feed intake increased at increasing densities. The survival, mean body weight, mean total length and specific growth rate were stocking density dependent. Best growth and survival rates were recorded in stocking density 5 than 10 and 15. This study showed that increased stocking density results in increased activity (air breathing, swimming) and decreased aggression.
