Aquaculture

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants.[1][2] Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish.[3] Mariculture refers to aquaculture practiced in marine environments. http://en.wikipedia.org/wiki/Aquaculture
