1. Pond selection: The pond for crucian carp culture requires leeward and sunny, and the best size is 30-35 mu. If you want to raise more, it is best to open more ponds, and it is not recommended to expand the pond area. When raising crucian carp, the water depth should be above 1.5m, drain the pond, and then expose it to strong light for a period of time. With exposure, many plants at the bottom of the pond will grow. At this time, it is necessary to clean up the weeds and other sundries at the bottom of the pond, and finally disinfect them with lime powder before releasing water.

2. Selection of crucian carp varieties: Common crucian carp varieties include * crucian carp, Xiangyun crucian carp, high-backed crucian carp and white crucian carp. It is best to choose high-backed crucian carp in weeding garden. When the high-backed crucian carp is generally two years old, the largest is 1 kg, and at least it weighs six times. At the age of three, it can generally grow to 4 kg each. The growth cycle of high-backed crucian carp is relatively short, the growth head is big and the meat is much. It is very important to do these steps well if crucian carp wants to grow bigger!

3. Choice of feed: Fish farming needs feed besides aquatic plants and natural bait in ponds. When crucian carp is young, its body length is 15 cm, which is mainly composed of natural bugs, shrimps and plant seeds. As its body grows to more than 15 cm, it needs to be fed. It is suggested to choose feed with protein content of at least 30% and increase phosphorus content. It is best to cooperate with aerobic equipment. The feed quantity of crucian carp is not invariable. When crucian carp has a large appetite, such as spring, it is necessary to feed more, and pay attention to less feeding in winter. Only when it suits the temper of crucian carp can it grow fat, grow fast and grow big.

4. Selection of breeding methods and release of seedlings; Carassius auratus culture is generally divided into three ways, namely: fry culture, adult fish intensive culture and mixed culture. Carassius auratus splash water generally enters the pond in the middle and late April, that is, at this time, 10000 to 25000 fish can be thrown per mu, and it can be increased to 3- 10 fish per catty by the end of the year. The yield per mu is 800- 1200 Jin.
