1. Plant feed: Carp fry can be fed with some common plant feeds, such as algae, moss, aquatic plants, weeds, fruits and vegetables. These feeds contain more vitamins and trace elements, which can enhance their resistance and immunity. However, it is easy to carry eggs or pesticides on plant feed, so it is best for breeders to clean them with potassium permanganate solution before feeding to avoid eggs and pesticide residues.

2. Animal feed: Carp fry still have a high demand for nutrition. If breeders want them to grow faster, they can feed some animal feed. The animal feed suitable for them to eat is Cyclops, fish insects, paramecium, wigglers, water earthworms and so on. These foods contain more protein and fat, which can meet their nutritional needs.

3. Synthetic feed: Breeders can also feed with synthetic feed, because the nutrition in synthetic feed is comprehensive, and feeding synthetic feed can ensure their comprehensive nutrition.

Carp has a large appetite, and the juvenile carp has a large demand for nutrition, so the breeder can feed it twice a day. The feeding time can be 9:00 a.m. and 3:00 p.m., and the amount of each feeding can be finished within 5-10 minutes.

Although they don't require high water temperature, if the water temperature is too low, they will lose their appetite. If the water temperature is low, the breeder should feed it once a day instead. In the coldest part of winter, carp will stop eating for a period of time, at which time breeders do not need to feed.
