In optimizing controlled fish production, a number of parameters directly related to the stocking density, including water quality, fish nutrition and the size physiological stage of the fish, the type of production system, and the type and size of the rearing tanks, must be considered (Malson and Held, 1992; Tidwell and Webster, 1993; Bagley et al., 1994).

There have been different researchers concerning different species of catfish all over the world because it commands very good commercial value in Nigerian markets (Ezenwayi, 1985; Anyinla et al., 1994). Stocking density at best density still attract attention of researchers because these factors are aimed at yielding a higher profit for the farmer and getting good quality fish at a reasonably short period of time.
