| 摘 要： | 于2017年6月至2018年5月在平潭岛东北部近岸海域开展污损生物生态研究，探讨了该海域大型污损生物的群落结构特点及演替趋势。周年模拟挂板试验结果显示，该海域大型污损生物隶属13门92种，以广分布暖水种为主，其中主要优势种为营固着生活的网纹藤壶(Amphibalanus reticulatus)、大室别藻苔虫(Biflustra grandicella)、三角藤壶(Balanus trigonus)和中胚花筒螅(Ectopleura crocea)，以及自由生活的廉形叶钩虾(Jassa falcata)和齿掌细身钩虾(Maeropsis serratipalma)等。虽然该海域全年均有生物附着，但附着强度的季节性差异显著，附着盛期为6月至8月(生物量介于7 326.0～12 970.0 g/m2之间，以湿质量计)，12月至次年2月(生物量介于39.5～1 580.5 g/m2之间)为附着淡季，而且污损生物摄食类型以悬浮物食者为主。温度和盐度是影响污损生物附着和分布的主要环境因素，水体透明度、水动力条件、地表径流和养殖等人类活动对污损生物的分布也有重要影响。

| Abstract: | To better understand the ecological characteristics of the macro-fouling community in the northeastern waters of Pingtan Island, East China Sea, a study was conducted by test panels from June 2017 to May 2018. A total of 92 species of fouling organisms belonging to 13 phyla were recorded. The community composition was dominated by coastal warm-water species, and the main dominant species were sessile Amphibalanus reticulatus, Biflustra grandicella, Balanus trigonus, Ectopleura crocea, and motile Jassa falcata, and Maeropsis serratipalma. Bioattachment occurred throughout the year, the main period of settlement extended from June to August (the biomass ranged from 7 326.0 g/m2 to 12 970.0 g/m2), and the off-seasons of settlement extended from December to February of next year (the biomass ranged from 39.5 g/m2 to 1 580.5 g/m2). The main functional feeding group of macro-fouling organisms was suspension feeder. Temperature and salinity were the most important environmental factors affecting the geographical distribution of macro-fouling organisms. Water transparency, hydrodynamic conditions, surface runoff as well as human activity (such as aquaculture production) also had important impact on the settlement of macro-fouling organisms. |
