Artificial catfish can be fed with live bait such as small fish, shrimp, loach, earthworm and red worm, and small fish can choose food fish, carp and crucian carp, which are the favorite foods for catfish. In addition to these animal feeds, breeders can also feed catfish with some synthetic feeds. Because catfish eats a lot, if only animal feed is fed, the cost is relatively high. Animal feed can be selected to be fed together with synthetic feed, which can not only ensure their adequate nutrition, but also maintain balanced nutrition. Catfish like to prey in the early morning and evening, because the temperature changes greatly at this time, so it is best to feed in the early morning or evening when cultured artificially.

Catfish will starve to death if they don't eat, and all fish may starve to death if they don't eat. But catfish are very adaptable, and short-term cessation of eating will not have much impact on their health. Moreover, their ability to endure hunger is relatively strong. If they are not fed, catfish can persist for about one month. Although they can persist for a long time, it is best to feed them regularly, so that they can grow faster and have better physique.
