Asian carp has a horseshoe-shaped mouth at the front of its head, and there are two pairs of fish whiskers beside it. Carp's eyes are relatively small and located above the longitudinal axis of the fish head. The average body length of carp is about 35 cm, but the longest can exceed 100 cm. Carps sold in the market are generally above 1 kg. Carp scales are large and cross-shaped. Even if the carp dies, the scales are not white. Carp, regardless of its size, has 36 scales, each with small black spots and even ribbed scales throughout the fish. Both dorsal fin and gluteal fin have hard spines, and the trailing edge of the last thorn has serrations. The lower leaves of caudal fin are mostly red.

Asian carp is a Cyprinidae fish native to Asia, which is the general name of herring, grass carp, bighead carp, silver carp, crucian carp and carp. Asian carp can consume 40% of their body weight of aquatic plants, plankton or wild mussels every day. Asian carp is a famous invasive species in the United States, which has invaded the Great Lakes of North America. This caused great panic among the American people, and the issue of Asian carp even entered the agenda of the White House. The White House specially held the "Asian Carp Summit". Because the American people think that Asian carp will destroy the ecological balance, the movement of hunting Asian carp has arisen.
