Per square meter of 4 to 2000-3000-year-old fish fry, with fresh branches, copepods or powdered salmon material, turtle material for bait. Feed 2 to 4 times a day. After 15 to 20 days of feeding, the fry grows to 2 to 3 cm, and it is transferred to a fingerling pond.
(2) Breeding of fingerlings: The seedling pool area is 1~3 mu and the water depth is 1~1.5 meters. 2 to 3 cm per acre of summer flower seedlings 10,000. Feeding a variety of feeds according to local conditions, generally in the early stage with fish slurry plus powdered concentrate synthetic feeding, in the middle and later period with commercially available yellowtail or fork-tailed powdered fish material mixed with water and fed into groups.
