1. Carp is a benthic omnivorous fish that eats both meat and vegetables. The bait spectrum is wide, the snout bone is developed, and it often feeds on mud. Carp is also a low-temperature animal, and its body temperature changes with the change of water temperature, so it does not need to consume energy to maintain a constant body temperature, so the total amount of bait intake is not large. At the same time, carp, like most freshwater fish, belongs to a kind of fish without stomach, with short intestine and fast metabolism, so its feeding habit is to eat less and eat more. The digestive function of carp is closely related to the water temperature, and its feeding is seasonal.
2. Carassius auratus is an omnivorous fish that lives in fresh water. It is plump and graceful in swimming. The living standard of crucian carp belongs to the bottom fish. Generally speaking, they swim, feed and inhabit underwater. However, when the temperature and water temperature are high, you should also swim in the lower and upper layers of the water for food. ? Adult fish are mainly plant food. Because plant feed is rich in water, there are many kinds of edible plants. The stems, leaves, buds and fruits of vascular plants are the favorite foods of crucian carp, and crucian carp can obtain various rich nutrients in the waters where higher aquatic plants such as water chestnut and lotus root grow.

The crucian carp in February-April and August-65438+February are the fattest. Except the western plateau, it is widely distributed all over the country. Crucian carp has strong adaptability, and can survive in deep or shallow water, running water or still water, high temperature water (32℃) or low temperature water (0℃). Even in strongly alkaline waters with pH:9 of 9, Dali Lake with salinity as high as 4.5% can still grow and reproduce.
Feeding time varies from season to season. Spring is the peak season for feeding, feeding day and night; The feeding time in summer is morning, evening and evening; Feeding all day in autumn; In winter, they eat at about noon. ?
