摘要:

广西海洋研究所在1990年~1992年对广西海岛周围水域进行了海洋生物资源调查,其中棘皮动物调查的结果为20科26属42种,得出了详细的种名录。据此调查可知,蛇尾纲的种数最多。4岛区中,涠洲-斜阳岛区分布的种类数最多。垂直分布上则只分布在中潮带和低潮带,在高潮带无分布。涠洲-斜阳岛区的自然条件适宜海参的生长,因此建议在涠洲建立花刺参的增养殖场。

Abstract:

From 1990 to 1992,Guangxi Institute of Oceanography carried out a research on marine biology resources in the watershed around islands of Guangxi. There found results of 20 families and 42 species of echinoderm enclodsed with detailed items of species. The Ophiuroidea has most species. Most species are distributed in the areas of Weizhou and Xieyang islands; Furthermore, they are only distributed in mediumtide zone and low tide zone, while are not in high-tide zone. The natural conditions in the areas of Weizhou and Xieyang islands are suitable for sea slugs. Thus, we may set up a breeding farm in Weizhou island for cultivating the sea slugs named Stichopus variegdtus Semper.
