[0002] The steps for cultivating black spot catfish seedlings are as follows:

[0003] Open-mouth cultivation: 3-5 days after the fertilized eggs are hatched, they are artificially domesticated by feeding them with egg yolk water 4 times a day. After 10-15 days of feeding with egg yolk water, they are fed with small water fleas 4 times a day. The amount of each feeding is 10% of the total body weight of the fry. After 30-40 days of feeding, the fry are placed in a breeding tank for flowing water cultivation. The water temperature is 11-12℃ and the dissolved oxygen in the water is above 6mg / l.

[0004] Fry cultivation: 70 days after hatching, start feeding water silkworms, feeding 4 times a day, each feeding amount is 15% of the total body weight of the fry, and the feeding period is 90-120 days; thereafter, start feeding chironomid larvae, the size of the fry has reached 2-3cm or more, feed 3 times a day, each feeding amount is 5-10% of the total body weight of the fry, cultivate in flowing water, the water temperature is 11-12℃, and the dissolved oxygen in the water is above 6mg / l.
