NATIONAL FISHERY RESOURCES, A FACT SHEET
Aquaculture is the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants in order to increase for production.
The need for aquaculture
Growing populationy of the world
Search for new protein sources
Demand for low fat food
Over fishing
Pollution
Fish domestication
By domestication, we mean the transfer of an organism from its natural habitat to a captive environment.
Cultivation system
Monoculture: Cultivation of single specie in the water body.
Polyculture: A combined cultivation of some species and size in the same body of water e.g Polyculture in Israel: carp + Tilapia + Silver Cap + Mullet
Economic and Health benefit of fish
The contributions of fisheries to the nations economy are significant in terms of employment, income generation, poverty alleviation, foreign exchange earnings and provisions of raw materials for animal feed industry. It is estimated that over 2 million Nigerians are actively engaged in primary and secondary fisheries operations such as fisher folks, fish farmers, fish processers, marketers, operators, on board industrial fishing fleet, terminal/jetties operators, industrial fishing fleet, net-makers, etc. the fisheries sub-sectors is estimated to have a value of N143.33 billion contributing 3-4 % to the GDP. Given Nigeria vast capacity for fish production, especially from aquaculture, this could be doubled in ten years to include more than a million tons of fish export. Fisheries also occupy a significant position in the primary sector, providing direct employment for over a million people and contributing about 50% of the animal protein intake of the over 150 million population. The FAO (food & agriculture Org.) estimated that 50% of fish consumed is catfish and farm raised fish. Global capture fisheries and aquaculture production accounts for 15% of all animal protein produced and consumed globally. There are several evidences suggesting that fish can play an important role in maternal, foetal and postnatal nutrition. An adequate amount of essential fatty acids (EFA) is important to health (i.e. reduces blood pressure, risk of coronary heart disease and possible anticancer effects). Some studies showed that fish and fish oil consumption significantly improve the outcome of pregnancy and infant development.
Eating of fish two or three times a week is thus encouraged as part of a healthy balanced diet both for child bearing women and the family at large.

- Total land area of Nigeria is 923,768sq km out of which 910,768 is land and 13000 is water.
- Inlandwater mass constitutes about 15 million hectares including natural land manmade lakes, rivers and reservoirs.
- The potential of fish farming in Nigeria is estimated at 5 million metric tons.
- New partnership for African Development (NEPAD) has recognized fisheries as a key instrument for increasing productivity, ensuring food security and improving market access for rural dwellers and strengthening Africans performance in global markets.
