UNDERWATER FARMING
Aqua-farming will be the grocery store of the future. It is the farming of aquatic organisms such as fish, crustaceans, molluscs, seaweed, oysters, shrimp and aquatic plants. Aqua-farming involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Broadly speaking, the relation of aquaculture to finfish and shellfish fisheries is analogous to the relation of agriculture to hunting and gathering.
