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.
