黄海北部仿刺参浮游幼体发生与附着习性的初步研究

于1997－1998年对黄海北部大长山岛自然海区仿刺参（Apostichopus japonicus）浮游幼体的发生与习性进行了研究。用浮游生物拖网在海上定期、定点进行刺参浮游幼体调查，发现浮游幼体出现时间为7月15日－9月31日，幼体高峰出现时间为8月1日，最大资源生物量为70只／m^3。通过检查不同水层刺参浮游幼体的附苗效果，发现3m水层的附苗量最多。另外，通过海上试验和室内试验还对刺参幼体对附着基材料的选择性进行了试验。结果表明，在常用的几种采苗附着基中，幼体对棕绳、聚乙烯网片选择性最好，其次为锚流网衣和波纹板，对贝壳和胶带选择性最差。

Development and attachment of pelagic larvae of sea cucumber (Apostichopus japonicus)

Ecological characteristics of pelagic larvae of sea cucumber (%Apostichopus japonicus%) were observed by drawing phytoplankton nets in coastal area of Changhai Island, the natural spawning ground in northern Yellow Sea from 1997 to 1998. The sea cucumber larvae occurred from 15 July to 31 September with peak (70 inviduals/m+3) on early August. The pelagic larvae were distributed within 3 meters, and preferred attachment on palm cord and polyethylene nets to shells and adhesive tapes, mediate for net and wavy plates. Lanterns for scallop and mussel culture are also be used as a material for attachment of sea cucumber larvae in large scale production.
