按从北往南的顺序,综合分析我国渤海、黄海、东海和南海污损性无柄蔓足类的种类组成、分布状况和季节变化等特点。污损性无柄蔓足类在中国沿海主要有34种,其中纹藤壶(Balanus amphitrite amphitrite)、网纹藤壶(B.reticulatus)、糊斑藤壶(B.cirratus)、三角藤壶(B.trigonus)、泥藤壶(B.uliginosus)、钟巨藤壶(Megabalanus tintinnabulum tintinnabulum)、高峰星藤壶(Chirona amaryllis)、白条地藤壶(Euraphia withersi)等种类均是沿海污损生物群落的优势种。纹藤壶在北方的渤海、黄海海区是主要的致污种类,网纹藤壶则在东海和南海沿岸海区占绝对优势。由北往南随着纬度的降低,污损性无柄蔓足类的附着期明显延长,甚至出现全年均可附着的现象,而且其种类数量也有所增加。海水盐度和离岸距离也是影响污损性无柄蔓足类分布的关键因素。
The ecological characteristics of fouling acorn barnacles in Bohai Sea,Yellow Sea,East China Sea and South China Sea,including species composition,distribution,and seasonal variation are stated in this paper.Thirty-four species of fouling acorn barnacles were found in Chinese waters.The dominant species are Balanus amphitrite amphitrite,B.reticulates,B.cirratus,B.trigonus,B.uliginosus,Megabalanus tintinnabulum tintinnabulum,Chirona amaryllis,and Euraphia withersi.The acorn barnacle B.amphitrite amphitrite is dominant species in the costal waters of Bohai Sea and Yellow Sea.However,the predominant species of acorn barnacles is B.reticulatus in the East China Sea and South China Sea.The settlement period of fouling acorn barnacles is usually in summer and autumn.Due to the decrease of latitude from north to south,the settlement period of fouling extends even to the whole year.The species numbers of fouling acorn barnacles also increased.Moreover,the environment factors,such as salinity and distance to shore also play an important role in the distribution of fouling acorn barnacles.
