The invention provides a method for breeding artificial seedlings of rough 
sea cucumber, which comprises the steps of cultivating parent 
ginseng, inducing oviposition, washing eggs and 
hatching, cultivating larvae, picking seedlings, cultivating immature 
ginseng, etc., wherein, spirulina 
powder, marine 
yeast  , aquatic 
yeast and bacillus as bait, not only the source of bait is convenient, but also saves the input of single-
cell culture facilities, and saves the manpower required for the culture of single-
cell algae bait, which can greatly save the cost of 
sea cucumber seedlings, and is beneficial to rough 
sea cucumber seedlings  promotion of breeding techniques.  Using the substitute bait to replace the living single-
cell algae can save about 25% of the investment in 
seedling raising facilities, and about 30% of the human investment in 
seedling raising, and the ratio of 
seedling raising input to output is 1:3.  Among them, the induction of spawning is carried out within 2 days of the first day of the 
lunar calendar and the 15th day of the 
lunar calendar, and the good effect of collecting eggs twice a month is obtained. The success rate of spawning induction is 83.3%, which solves the difficulty of inducing spawning of sea cucumbers.  technical problems.
