Comparative example 1:
the comparative example is basically the same as the example 1, except that in the step B, the characteristic that the pink wart sea cucumber is not influenced by the moon phase propagation rule is not utilized, all 130 parents are induced to spawn at one time, 2 parents spawn in total, about 2.8 ten thousand spawns are spawned in total, and the average spawning amount is 1.4 ten thousand spawns per parent.
Comparative example 2:
the comparative example is basically the same as the example 2, except that in the step C, the density of the air chambers is set to be 0.4 square meter/piece in the culture water body, the inflation strength of the air chambers is not reduced after the pink wart sea cucumber grows to the five tentacle attachment stage, the pink wart sea cucumber is in a floating state for a long time due to the fact that the air chambers are too dense and the inflation strength is too high, the attachment cannot continue to grow, and finally the seedling culture fails.
Comparative example 3:
the comparative example is basically the same as the example 1, except that in the step C, the water body is stirred by a manual stirring method, the bottom water body is stirred once every 1-3 hours, the water is changed after 3 people watch the water by turns for 10 days continuously, and the manual stirring is stopped. According to the comparative example, due to long-term alternate stream watching, the labor consumption is large, the uniformity of seedlings after stirring cannot be guaranteed, the seedling density in a partial area is too high, the uneven growth condition occurs, or due to untimely stirring, the seedlings die in an oxygen-deficient collective mode, and the seedling culture fails.
