Tilapia nursery breeding tank breeding and seedlings in two ways. Breeding pond rearing is the breeding of the broodstock, and the fry are bred in the original breeding pond so that the broodstock can reproduce the fry in the breeding pond. The first batch of fry, approximately 20 days after cultivation, can grow to a size of 3 cm. It is said to be a species of summer flower. At this time, the species of summer flowers can be caught and moved into adult fish ponds for commercial fish breeding. Dividing into ponds is to raise the fry in the breeding pond until it reaches 0.7 centimeters, then it will be caught and moved to a special fry pool to cultivate a special cultivation pond with an area of ​​1-2 mu and a water depth of 1 meter. When the broodstock is found to be spawned in the breeding pond for spawning, the pond should be cleaned, fertilized and cultivated. Generally 50,000 to 100,000 fish fry per mu. During feeding, the fertilizer should be traced according to the water quality, so as to keep the water quality stable. Generally, two times of soymilk is poured every day. Ten thousand grams of bean cake is used per 10,000 fry during the breeding period of 20 days. When fish fry grow to a size of 1-1.5 cm in diameter, they can be caught and transferred to adult fish ponds for commercial fish breeding.
