南海北部沿岸污损生物中的苔藓虫

Bryozoan of fouling organisms in coastal waters of northern South China Sea

作者于1979年9月至1989年8月,先后在广东、海南及广西沿岸港湾进行污损生物和人工鱼礁附着生物周年挂板试验,并调查沿岸港湾浮标、船只、码头、水产养殖设施及其他水下设施的污损生物,获苔藓虫3871号标本,经分析鉴定为88种,隶属3目30科。它们多数是高盐暖水种和广分布种。有少数河口低盐种,遍布于中国沿岸的有26种,黄、渤海已发表的有29种,东海31种,仅南海沿岸水域28种。南海北部沿岸苔藓虫终年都能繁殖附着,附着高峰期为冬春季节的低温月份。

This paper is written on the basis of the panel experiments of fouling organisms and attached organisms of artifical fish reefs carried out along the coastal waters in Guandong, Hainan and Guanxi from September, 1979 to August, 1989. Biofouling organisms surveys were also made on bouys, ships, wharfs, aquaculture facilities and other underwater construction.88 species of Bryozoans are obtained from 3 781 samples which belong to 30 families in 3 orders. Most of them are haline warm water species and widely distributed species, only a few of estuarine low saline species and on cold water species are found. Among the 88 species 26 are widely distributed in China' s coastal waters, 29 in the Yellow Sea and Bohai Sea, 31 in the East China Sea and only 28 in the South China Sea.Bryozoans in the northern South China Sea repreduce and attach all the year around. Attachment bloom appears in winter-spring months of low temperature.
