AN ECOLOGICAL STUDY OF FOULING ORGANISMS IN XISHA ISLANDS

Monthly and seasonal panel experiments were carried out in the Yongxing Island from September 1979 to August 1981.Altogether 119 species of fouling organisms are collected, of which, Hydroides elegans, Serpula vermicularis, Scrupocellaria longispinosa, Amathia distant, Enteromorpha spp.and Ostrea spp.are dominant species.Fouling of organisms may occur all the year round with evident seasonal variations, Species succession in the process of community formation is very evident and the climax has arrived after two years.Great variation exists between fouling organisms in different years and at different stations.
