1, pond condition: pond area15mu, pond depth 2m, water depth1.5m, and pond sediment about10cm.

2. The length of fry stocking specification is more than 5 cm, and the stocking density is 500.

3. There are mainly two kinds of feed for feeding, namely, feeding chicken and duck viscera in the early feeding period and feeding wild fish in the later feeding period. Feed needs to be crushed before feeding.

4. When Silurus meridionalis is reared and domesticated, the rearing and domestication method in the early stage of breeding should be adopted. Domesticating the catfish to feed on all sides of the pond, then feeding on three sides of the pond, then gradually domesticating to feed on one side of the pond, and finally feeding at a certain point can improve the utilization rate of feed, make the catfish similar in size and improve the survival rate of culture.

5. Daily management, patrol the pond regularly, carefully observe the feeding and activities of catfish, and handle problems in time when found. The catfish has a fierce feeding habit, and cannibalism among the same species is more serious. Therefore, it is necessary to regularly raise at different levels to reduce the killing of individuals due to large differences in specifications.

6. Prevention and treatment of diseases Because Tianjin is located in North China, the average and maximum temperatures in spring and summer are higher than those in the origin of catfish, so we should pay attention to the prevention and treatment of diseases in summer. In hot season, Silurus meridionalis suffers from enteritis. Treatment with oxytetracycline as bait, the dosage is 50Mg/kg-80mg/kg, and it can be cured in 7 days.
