| Abstract: |
| A fouling study was conducted in coastal waters southwest of the East China Sea between December 2013 and November 2014. A total of 84 species of fouling organisms belonging to 69 genera, 49 families, and 10 phyla were recorded over the entire year. The community composition was dominated by coastal warm-water species belonging to typical subtropical inner bay communities. The prosperous stage of settlement lasted from April to September, and the adhesion strength of the fouling organisms was the highest in summer. Sessile suspension feeders constituted the main core of settlement for the fouling community. Amphibalanus reticulatus was the most dominant and representative species of fouling organism, and other dominant species included Caprella equilibra, Ectopleura crocea, Anthopleura nigrescens, Stylochus ijimai, Spirobranchus kraussii, Crassostrea angulata, Perna viridis, Jassa falcata, Stenothoe valida, Sphaerozius nitidus, and Biflustra grandicella. The individuals in the fouling community showed a mutual dependence or constraint relationship due to competition for settlement space and food, and they exhibited a particular spatiotemporal distribution in accordance with adaptation to environmental factors. Temperature was the most important environmental factor determining the geographic distribution of fouling organisms. The temperature characteristics of species essentially reflect the differences in the fouling community composition in various climate zones. The species number, settlement stage, and settlement rate of fouling organisms are closely related to water temperature. Local natural environmental conditions (salinity, water currents, light, etc.) as well as human activity (such as aquaculture production) are all important factors affecting the settlement of fouling organisms. |

| 于2013年12月~2014年11月在东海西南近岸海域进行污损生物周年挂板试验，全年共记录污损生物10门49科69属84种，群落组成以近岸暖水种为主，为典型的亚热带内湾型群落，附着盛期为4–9月，夏季污损生物的附着强度最高。固定生活类型的悬浮物食者是该近岸海域污损生物群落的附着主体，网纹藤壶（Amphibalanus reticulatus）是最主要的优势种和代表种，其它优势种还有长鳃麦杆虫（Caprella equilibra）、中胚花筒螅（Ectopleura crocea）、太平洋侧花海葵（Anthopleura nigrescens）、今岛柄涡虫（Stylochus ijimai）、克氏无襟毛虫（Spirobranchus kraussii）、近江牡蛎（Crassostrea rivularis）、翡翠贻贝（Perna viridis）、廉形叶钩虾（Jassa falcata）、强壮板钩虾（Stenothoe valida）、光辉圆扇蟹（Sphaerozius nitidus）和大室别藻苔虫（Biflustra grandicella）等。污损生物群落个体间因附着空间和食物竞争而存在着相互依存或互相制约的关系，又依照对环境因子的适应性而存在着一定的时空分布规律。温度是决定污损生物地理分布的最主要环境因素，物种的温度属性是不同气候带污损生物群落组成差异的本质体现，污损生物的种类数、附着期和附着量与水温有着密切的关系；另外，盐度、水流、光、水产养殖等自然环境或人为因素也是影响污损生物附着的重要影响因子。 |
