A large number of diseased fish fry floated on the surface of the water and could not be fed. After a few days of spinning, they sank and died. 15-20-day-old larvae were the most likely to get sick and the death peak appeared. (3) Prevention and control methods to increase the amount of water exchange and improve culture.

(2) the gastric sac of symptomatic diseased fish was particularly dilated, and the dorsal abdominal wall of some fish was expanded and ruptured, and the whole gastric sac was separated from the fish body. A large number of diseased fish fry floated on the surface of the water and could not be fed. After a few days of spinning, they sank and died. 15-20-day-old larvae were the most likely to get sick and the death peak appeared.

(3) to increase the amount of water exchange and improve the breeding environment, it is not suitable to feed Artemia nauplii alone, but to feed copepods early, strengthen the nutrition of larvae and juveniles, and strictly control the water quality.
