The effect of different feeding rates and restriction on the growth performance of Clarias gariepinus
Fish is a primary source of protein for many persons in the world (Rameshguru et al., 2011). However increase population pressure not adequately matched with fish production has caused more demand pressure on the fisheries sector. Hence, there is a need to increased aquaculture production to solve this problem associated with the market demands of fish and fish products (Aydin et al., 2011). The species of high yield potential for aquaculture production in Africa are the Nile tilapia (Oreochromis niloticus), common carp (Cyprinus carpio) and African catfish (Clarias gariepinus) (FAO, 2008). Production of these species has been with the addition of organic manures to pond water so as to stimulate the growth of natural food organism (Robinson and Li, 1999). However, supplementary feeding has become widely practiced in modern aquaculture in the quest for improvingproductivity. Feeding now accounts for above 60% of the total cost of fish production in Africa, hence, determining the viability and profitability of fish farming enterprise (Jamu and Ayinla, 2003). Commercial diets commonly used are very expensive and fed to fish at different self-determined rate and feeding frequencies so as to break even. Fish farmers also prepare on-farm feed using alternative feedstuffs which are locally available, cheap and usually unconventional so as to reduce the cost of production and maximize profit.
