摘要 为了解经过不同表面处理的人工鱼礁模板的附着生物群落特征,于2014年8月对大亚湾圆洲岛已投放的鱼礁模板进行采样调查。结果表明,共采集和鉴定出附着生物39种,黑缘牡蛎(Ostrea nigromarginata)占据附着生物优势种的绝对地位;经过表面处理的混凝土模块的附着生物生物量及丰度较高,而红砖、花岗岩板和未经表面处理的钢筋混凝土模板的附着生物生物量及丰度都很低;附着生物的生物量和丰度与其群落特征的变化未表现出一致的规律性。

Abstract In order to understand the biological community characteristics of different surface treatments of artificial reef templates, which had been placed on the offshore, Round Island,Daya Bay. Sampling survey was taken in August of 2014.The results showed that 39 kinds of fouling organisms were collected and identified,Ostrea nigromarginata has attached the absolute position of the dominant species; Through the concrete block surface treatment has a better biofouling effect,and red brick,granite plates and nosurfacetreated concrete template attached biomass and abundance of organisms are very low; Biomass and abundance indices and ecological indices do not show a certain degree of regularity.

大亚湾地处亚热带,位于珠江口东侧,面临南海,是一个半封闭海湾。圆洲岛是大亚湾众多岛屿之一,面积约0.074 km2,是广东省专门在大亚湾设立的3个珊瑚自然移植区之一。
附着生物的种类组成和数量变化是人工鱼礁饵料效应的重要体现[1],是评价人工鱼礁生态效应的重要指标。人工鱼礁的表面积和外露面形态是影响礁体饵料效应的重要因素[2],外露面的形态直接影响礁体生物附着效果。研究表明,钢筋混凝土人工鱼礁对海洋生物的诱集效果明显高于油井类、舰船类等人工鱼礁[3]。……
