[0002] With the development of my country's economy, sea cucumbers, as a species with high nutritional value, are becoming more and more popular. The sea cucumber seedling and breeding industry has developed accordingly. Traditionally, artificial sea cucumber seedling technology is used to cultivate planktonic larvae. Generally, there are the following methods: one is the siphon method; the second is the trawl method; the third is the net cage concentration method; the fourth is direct cultivation in the original hatching pool. The siphon method is more commonly used, which is to rely on the pressure of the water level difference to use a rubber or plastic siphon tube to suck the larvae from the hatching pool into the cultivation pool. Before siphoning, stop aerating the hatching pool and let it stand for about half an hour, suck out the deformed, unhealthy and dead embryos and dirt at the bottom of the pool, then add a small amount of oxygen and stir the pool, count, and suck the larvae into the cultivation pool according to the planned pool density.
