Cultivation of fish and shellfish
Aquaculture, also known as
aquafarming, is the farming of aquatic organisms such as
fish,
crustaceans,
molluscs and
aquatic plants. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with
commercial fishing,
which is the harvesting of wild fish. Mariculture refers to aquaculture practised in marine environments.
The output, as reported, from aquaculture would supply one half of the fish and shellfish that is directly consumed by humans. However, there are issues about the reliability of the reported figures. Further, in current aquaculture practice, products from several pounds of wild fish are used to produce one pound of a piscivorous fish like salmon.
Particular kinds of aquaculture include fish farming, shrimp farming, oyster farming, algaculture (such as seaweed farming), and the cultivation of ornamental fish. Particular methods include aquaponics, which integrates fish farming and plant farming.
