The small cage is inserted into the pond with fresh water. The corners of the box are fixed and flat. 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.

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. Can also be used fish meal, silkworm cocoon powder, bean cake powder, wheat bran, third powder and multi-vitamin, a small amount of minerals and other raw materials in proportion made of powdered formula feed, add water to tune into the group feed. Two feed stations were set in each pond. Feed was fed on the feed table and fed 2 to 3 times a day. Daily feeding amounted to 4% to 6% of fish's body weight. Routinely do water management, oxygenation, disease prevention and other management work. By the end of the year, the species can grow to 12-15 cm and the body weight can reach 30-50 grams, and then grow into adult fish.
