Fish farming is the sub-set of aquaculture that focuses on rearing of fish under controlled or semi-controlled conditions for economic and social benefits. Aquaculture is the rearing of aquatic organisms under controlled or semi-controlled conditions for economic and social benefits. Aquatic organisms include fishes, molluscs, crustaceans and aquatic plants. Culture implies some forms of intervention in the rearing process to enhance production such as regular stocking, feeding, protection from predators etc Food and Agricultural Organization (FAO, 2006).
In Nigeria, the production of food has not increased at the rate that can meet the increasing population. While food production increases at a rate of 2.5%, food demand increases at a rate of more than 3.5% due to high rate of population growth of 2.83% (Ojo & Fagbenro, 2010). The apparent disparity between the rate of food production and demand for food in Nigeria has led to a food demand supply gap thus leading to a widening gap between domestic food production and total requirement, an increase resort to food importation and high rates of increase in food prices and as a result, wide spread hunger and malnutrition are evident in the country (Ugwumba & Chukwuji, 2010).
