Extended information:

Carp, commonly known as carp, maozi, etc., belongs to the carp family. The sides of the body are flat and the abdomen is round. The mouth is horseshoe-shaped and has 2 pairs of barbels. The base of the dorsal fin is longer, and both the dorsal and anal fins have a thick, serrated spine. The sides of the body are golden yellow, and the lower leaves of the tail fin are orange-red. Carp usually inhabit the bottom of water bodies covered with aquatic plants in rivers, lakes, reservoirs, and ponds, and feed mainly on benthic animals.

It has strong adaptability, resistance to cold, alkali and hypoxia. Eggs can be laid in running water or still water. The egg-laying places are mostly in aquatic plants. The eggs adhere to the aquatic plants and develop. Carp is one of the freshwater fish with the largest variety, widest distribution, longest breeding history and highest yield.

Carp is a benthic omnivorous fish that eats both meat and vegetables. It has a wide bait spectrum and a well-developed snout bone, and it often digs into the mud to feed. Carp is a low-temperature animal, and its body temperature changes with changes in water temperature. It does not need to consume energy to maintain a constant body temperature, so the total amount of bait required is not large. At the same time, carp, like most freshwater fish, is a stomachless species with a short and slender intestine and a fast metabolism, so its feeding habit is to eat less and more frequently. The digestive function of carp is closely related to water temperature, and the seasonality of feeding is very strong.
