珍珠贝在南海北部海洋结构物上的分布

:1 98 6— 1 995年在南海北部水域对 1 6个海洋结构物 (其中 1 2个生物调查浮标 ,2个Marex水文资料浮标和 2个固定石油生产平台 )上珍珠贝科 (Pteriidae)的水平和垂直分布进行了调查 ,共发现有珍珠贝科 2属 1 0种。文中讨论了它们的分布与该水域的海流特征、结构物离岸距离及珍珠贝幼虫发育的关系 ,并认为 ,企鹅珍珠贝Pteria(Magnavicula)penguin、短翼珍珠贝P .(Austropteria)brevialata和珠母贝Pinctadamargartifera、鹌鹑珍珠贝Pteria (A .)coturnix将分别为B2站、YM1站和Z1站海区未来海洋结构物污损生物的优势种。

PRELIMINARY STUDIES ON PEARL OYSTER ON OFFSHORE STRUCTURES IN NORTHERN SOUTH CHINA SEA

The horizontal and vertical distributions and individual sizes of different pearl oyster species on 16 offshore structures(12 biological buoys,2 Marex hydrological buoys and 2 fixed production platforms) in the northern South China Sea were investigated during the period from 1986 to 1995.Ten species in two genera of pearl oyster were collected.The relations between their distributions and some factors such as current characteristics,the distance of structure to coast and the larvae growth conditions are discussed.It is concluded that Pteria (Magnavicula) penguin,P. (Autropteria) brevialata and Pinctada margaritifera,Pteria (A.) coturnix will be future dominant species of the fouling communities on the future offshore structures in the sea areas of B2,YM1 and Z1 buoy stations.
