雷州半岛东南海域污损浮标的大型藻类
Fouling Macroalgae on Navigation Buoys Southeast of the Leizhou Peninsula, Northern South China Sea
摘要
Abstract
Macroalgae are common constituents of fouling communities. Their colonization can damage protective coatings, add loading, increase corrosion risk and even may result in position change of buoys. Under such circumstances the service time of buoys will be shortened. In order to elucidate the fouling pattern of macroalgae in winter on buoys deployed in waters southeast of the Leizhou Peninsula, located in tropical zone, northern South China Sea and the relationship between the macroalgal community and duration of buoy deployment, a navigation buoy investigation was conducted in early February 2015. The results indicate that only 2 species of green algae,Enteromorpha prolifera and Ulva lactuca, were observed on the water line of buoy A, which was deployed for 6 months. However, a total of 6 species, including the green algae,E. prolifera,E. intestinalis,U. lactuca, and U. fasciata, and red algae Grateloupia livida and Ceramium tenerrimum, were identified from the samples collected on the water line and submerged upper side hull of buoy B deployed for 19 months. No algae were found on the lower part of the side hull and bottom of both buoys. It can be concluded that colonization of green algae occurred earlier than the red algae and the number of species of fouling macroalgae increased with time. The green algae,E. prolifera,E. intestinalis,U. lactuca and U. fasciata, favour strong light and have vigorous reproductive capacity and were the forerunners in the algal fouling community. Moreover, water line regions of buoys were fouled by green algae and slightly deep parts mainly by red algae, particularly C.tenerrimum. The vertical distribution pattern should be closely related to the type and proportion of pigments in macoralgae and the penetrability of light in seawater. This study provides basic data useful for the prevention and control of fouling organisms on navigation buoys in the northern South China Sea and it may also be helpful in understanding the ecology of macroalgae on artificial facilities in the South China Sea.关键词
