为了解人工鱼礁的生物附着状况,于2008年6月和7月,对大亚湾杨梅坑人工鱼礁区中已投放1 a的混凝土礁体和铁制礁体上的附着生物进行了调查。2次调查共采集和鉴定出附着生物94种。其中,混凝土礁体附着生物种类达到73种,总生物量为27903.50 g/m2,多样性指数为4.68,均匀度指数为0.76。铁制礁体种类达到80种,总生物量为23023.00 g/m2,多样性指数为4.53,均匀度指数为0.72。人工鱼礁投放1 a后,礁体表面100%被生物所覆盖,三角藤壶(Balanus trigonus)是人工鱼礁区占据绝对优势的种类,其优势度达到0.1464。
In order to understand the biological attachment of artificial reefs, the attached organisms on the concrete reefs and iron reefs that had been put on for 1 year in the Yangmeikeng artificial reef area of Daya Bay were investigated in June and July 2008. Two surveys collected and identified 94 species of attached organisms. Among them, there were 73 species of organisms attached to concrete reefs with a total biomass of 27903.50 g / m2, a diversity index of 4.68 and a uniformity index of 0.76. The number of iron reef species reached 80, the total biomass was 23,023.00 g / m2, the diversity index was 4.53 and the evenness index was 0.72. After artificial reefs were put into operation for 1 year, the surface of the reef was covered with 100% organisms. Balanus trigonus was the dominant species in the artificial reef area with a dominance of 0.1464.
