Aquaculture is the farming of fish and other aquatic life in enclosures, such as ponds, lakes and tanks, or cages in rivers and coastal waters. China's 2005 reported harvest was 32.4 million tonnes, more than 10 times that of the second-ranked nation, India, which reported 2.8 million tonnes. [2]
China is the major producer of the grass carp, which grows quickly and requires fairly little dietary protein. Low-cost feed such as grain processing and vegetable oil extraction by-products, terrestrial grass, and aquatic weeds, allows the grass carp to be produced cheaply. [4] This fish is mainly sold fresh, either in pieces or whole.
Indeed, tilapiine cichlids have become an important farmed fish in Taiwan for both export and domestic consumption. [13] The Chinese name for the fish in Taiwan is wu-kuo (吳郭), and was created from the surnames of Wu Chen-hui (吳振輝) and Kuo Chi-chang (郭啟彰), who introduced the fish into Taiwan from Singapore.

In 2011, Sichuan province had 51 million pigs (11% of China's total supply). [33] In rural western China, sheep, goats, and camels are raised by nomadic herders. [34]
The fish-farming game isn’t much different than any other type of livestock farming. It involves crowded man-made environments that can leave farmed fish more susceptible to infections and disease.
After China and Taiwan, Vietnam is the third largest producer of farmed cobia in the world where production was estimated at 1500 tonnes in 2008. [2] The possibility is also being examined of growing hatchery reared cobia in offshore cages around Puerto Rico and the Bahamas.
