BIOFOULING ON THE BUOYS OFF THE QIONGZHOU CHANNEL AND LEIZHOU PENINSULA COAST,SOUTH CHINA SEA

Huang Zongguo Cai Ruxing Jiang Jinxiang Cai Erxi and Wu Qiquan (Third Institute of Oceanography, National Bureau of Oceanography)  
The navigation buoys moored at depths of 2 to 52 meters off the Qiongzhou Channel and Leizhou Peninsula coastal waters, Guangdong province, for 9 to 36 months were examined for biofouling (including species, percent coverage of surface, thickness, and wet weight) in 1967-1969. The results indicated that biofouling of buoys in these waters were generally more severe than those in the East China Sea. There are evident differences on the biofouling of buoys situated in various environments.According to the distribution of dominant species, the fouling communities on 41 buoys may be divided into three types: the open sea community, its main ecological characteristics are the large number of species, the marked dominant species, and the very high biomass, e.g. No. 3 buoy has in 9 months 20.7 m2 underwater surface and a wet weight of fouling organisms 862.1kg, only one dominant species (Megabalanus tintinnabulum tintinnabulum); the off shore mixed fouling community with relatively high biomass, e.g. No. 25 buoy has in 12 months 20.7m2 underwater surface and the wet weight of fouling organisms 498.5 kg, four major species (Balanus amphitrite amphitrite, B. reticulatus, Chirona amaryllis, and Perna viridis); the inner bay community, the number of species and the abundance are less than that of the first and second types, e.g. No. 36 bouy has a 9.9 m2 underwater surface and a wet weight of fouling organisms 149.5kg in 24 months, only one dominant species (B. reticulatus), but no M, t. tintinnabulum.
