Yellow-footed preserved fish will die when laying eggs, and there are specific drugs that can be saved. The stocking density should be neat to avoid killing each other. Generally, 2000 animals can be stocked in each cage in the standard thickness stage. After 1-2 months, the stocking density decreased to 1000. When the body length reaches 3-5 cm, the density will be adjusted to 200-500, and the breeding period will be maintained at 8- 10. Under the conditions of good marine environment and high management level, the maximum stocking density can reach 20 kg/m3.
