摘要
1991年6月至1992年5月在汕头港进行污损生物挂板实验，同时调查港区浮标、码头和船底的污损生物，调查方法采用国家海洋调查规范。获119种生物，试板72种，浮标和船底70种，码头54种。其中，泥藤壶、网纹藤壶、僧帽牡蛎、翡翠贻贝、太平洋侧花海葵、双枝薮枝螅和双节螅为优势种。汕头港一年4季都有生物繁殖附着，盛期是5～11月，高峰9月，月平均生物量1340g／m2，最高9月份，最低2月份，四季度板平均3219g／m2，高低依序为秋、夏、春和冬。试验结果表明，汕头港主要污损生物为沿岸广分布和河口低盐种，其特点是优势种突出，附着量很大。
An investigation of marine fouling organisms was conducted using monthly test panels from June 1991 to May 1992, in Shantou Harbour. The investigation included a survey offouling organisms on ship bottom, buoys and wharfs. The study method used was based onThe National Specification for Oceanographic Survey.A total of 119 species of fouling organisms were identified, of which 72 species werefound on test panels, 70 species on the buoys and ship bottom, and 54 species on the wharfs.The dominant species were found to be Balanus uliginosus, B. reticulatus, Ostrea cucullata,Perna viridis, Anthopleura pacthca, Obelia dichotoma and Bimeria francina. The foulingorganisms attach and reproduce all the year round in Shantou Harbour, flourishing from Mayto November and reaching to a climax in September. Ranging from 1 to 5 774g/m2, themonthly average biomass showed a maximum in September and a minimum in February,with a seasonal average of 3 219g/m2. The seas0nality in biomass showed a trend of autumnto summer>spring>winter. The results suggested that the fouling organisms in Shantou Harbour, with characteristics of preveiling domiant species and large amount of biomass, were the euryoecous or hypohalinous in their major species, which usually present along the coast or near an estuary.
