Asian carps

The species of heavy-bodied cyprinid fishes are collectively known in the United States as Asian carp. Cyprinids from the Indian subcontinent, for example, catla (Catla catla) and mrigal (Cirrhinus cirrhosus) are not included in this classification, and are known collectively as "Indian carp".

Nine Asian carp have been substantially introduced outside of their native ranges:

All the above, except largescale silver carp, have been cultivated in aquaculture in China for over 1,000 years. Largescale silver carp, a more southern species, is native to Vietnam and is cultivated there. Grass, silver, bighead, and black carp are known as the "Four Domesticated Fish" in China and are the most important freshwater fish species for food and traditional Chinese medicine. Bighead and silver carp are the most important fish, worldwide, in terms of total aquaculture production.Common carp and crucian carp are also common foodfishes in China and elsewhere. Goldfish, though, are cultivated mainly as pet fish. Common carp are native to both Eastern Europe and Western Asia, so they are sometimes called a "Eurasian" carp.

A long tradition of Asian carp exists in Chinese culture and literature. A popular lyric circulating as early as 2000 years ago in the late Han period includes an anecdote which relates how a man far away from home sent back to his wife a pair of carp (Chinese: 鯉魚; pinyin: Liyu), in which, when the wife opened the fish to cook, she found a silk strip that carried a love note of just two lines: “Eat well to keep fit” (first line) and “Missing you and forget me not” (second line).
