Asian carp is a grouping of fishes commonly used to mean silver, bighead carp, white and black amur,[note 1] which are regarded invasive in the United States. These four species, also known as copi, are native to China where they are collectively known as qing cao lian yong (青草鲢鳙) or si da jia yu (四大家鱼, "Big Four domesticated fish")[note 2] and are farmed for food.
