Fry of hybrid clariid catfishes, Clarias gariepinus x Heterobranchus bidorsalis, were reared at four densities in indoor aquaria to evaluate the effects of stocking density on survival, growth and feed utilization. Fish (mean weight 0.84g) were stocked into 41-L aquaria containing 12L of water at rates of 11, 22, 33, and 44 fish per aquarium (978, 1956, 2933 and 3911 fish/m3) respectively. Each treatment was replicated three times.
