摘要:

采用亲体培养、人工催产和幼虫培养等方法研究了可口革囊星虫(Phascolosoma esculenta)的人工繁殖技术。结果表明, 可口革囊星虫亲体可室内培养成熟; 阴干和降温刺激亲体能达到较好的催产效果; 球等鞭金藻(Isochrysis galbans)和亚心形扁藻(Platymonas sp.)可作为海球幼虫的主要饵料。海球幼虫体长生长速度较快, 日增长高达46 μm, 孵化后一周内, 幼虫体长达500 μm, 然后开始附着营埋栖生活。

Abstract:

Artificial breeding of Phasocolosoma esculenta was investigated through culturing bloodstocks. It was found that P. esculenta could be reared to mature in the lab. Either drying in the shade or dropping the temperature were very efficient to induce mature P. esculenta to spawn. Isochrysis galbans and Platymonas sp. could be used as the main feeds for pelagospheres. P. esculenta grew faster at the pelagospheres stage in comparison with other stages. Settlement for burrowing life started when their body length reached about 500 μm.

Key words: Phasocolosoma esculenta broodstock rearing artificial induce artificial breeding pelagosphere
