Abstract

Nigeria is the most populous black nation in the world, with an estimated population of about 150 million people. Its citizens as at the end of 2012 have a projected fish demand of 2.66 million tonnes of fish. Fish supply within the said period was 132 million tones. This figure was made up of 0.7 million tonnes from importation and 0.62 million tonnes from both artisanal and aquaculture.  Fish, a relatively cheaper source of food protein is very important in the diet of many Nigerians and is thus in high demand. The Nigerian fishery sector is characterized by a rich resource base, comprising of harvests from capture and culture. Due to over exploitation of the capture fisheries, the hope of the Nigerian fisheries is in aquaculture development. Production from aquaculture is increasing and supplied between 5 – 22% of total domestic fish production between 2000 and 2007.  For aquaculture to be sustainable, production systems must focus on the interactions between the culture techniques and the environment. It is pertinent to note that the growth and the expansion of aquaculture as an industry occurred during a period of growing concern of its environmental implications. Opportunities exist for the government to improve farm productivity through the promotion of appropriate responsible production, extension technologies and policy that is environmentally friendly.
