Nutrient enrichment method for promoting development of juvenile astrostroma rubrum

The invention belongs to the technical field of aquaculture, and discloses a nutrient enrichment method for promoting the development of juvenile astrostroma rubrum, which comprises the following steps: selecting 2-3-year-old parent astrostroma rubrum in April, placing the parent astrostroma rubrum in a net cage on the sea for intensive cultivation, and injecting oxytocic hormone for artificial spawning after the gonad is mature; after fertilization, collecting fertilized eggs and placing the fertilized eggs in a hatching device for hatching; after the fertilized eggs are moved into a hatching device, hatching water temperature and salinity are set; the fertilized eggs to be incubated are moved into a nursery pond which is disinfected in advance to incubate larva fish, and the larva fish obtained through incubation is fed and cultivated; and sequentially culturing the juvenile fish and the juvenile fish of the stellate red east in the nursery pond. According to the nutrient enrichment method for promoting the
