利用虾池养成的种参人工育苗应注意的问题

Artificial Breeding Technique of Broodstock of Sea Cucumber,Stichapus japocicus Raised in a shrimp Pond

虾池养成的种参性腺发育早,可提前产卵,但繁殖力不强。通常第一次产卵量较大,孵化率较高;第二次以后产卵量显著减少,且孵化率较低,难以形成批量生产。

The Stichapus japocicus broodstock cultured in shrimp ponds matured and spawned early without high efficiency.Usually,they released large amount of eggs and produced a great deal of larvae with high hatching rate in the first spawning, but not in the second spawning. Hence,it was difficult to produce larvae in large scale from the second spawning.
