aquaculture

详情

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. Broadly speaking, the relation of aquaculture to
finfish and shellfish fisheries is analogous to the relation of agriculture to hunting and gathering.[
Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.
According to the FAO, aquaculture "is understood to mean the farming of aquatic organisms
including fish, mollusks , crustaceans and aquatic plants. Farming implies some form of
intervention in the rearing process to enhance production, such as regular stocking, feeding,
protection from predators, etc. Farming also implies individual or corporate ownership of the
stock being cultivated."The reported output from global aquaculture operations 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.
