臺灣水族寵物貿易引進水生無脊椎動物種類之調查現況

The Survey of the Imported Aquatic Invertebrates via the Live Aquarium Ornamental Trade in Taiwan

本研究於2004年3月至2005年2月間，調查臺灣本島經由水族寵物貿易所引進的水生無脊椎動物，並紀錄這些物種的學名、原產地、數量與引入管道。研究中所記錄的108種引進種多來自熱帶地區，其中僅13種為淡水物種，其餘的皆為海水物種。在考量各物種的引進量、原產地環境特性與臺灣的相似性及是否有入侵記錄後，初步入侵風險的評估結果顯示，軟體動物腹足綱的Pomacea bridge和Indoplanorbis exustus及雙殼綱的Lima scabra、甲殼動物的Procambarus clarkia、Cherax destructor和Neocaridina sp.、刺絲胞動物珊瑚蟲綱的Cribrinopsis crassa、Condylactis passiflora和Alcyonium palmatum及缽水母綱的Phyllorhiza punctata具有較高的入侵風險。

In this study, the situation with imported aquatic invertebrates via the live aquarium ornamental trade in Taiwan was investigated from March 2004 to February 2005. The scientific names, native geographic regions, amount, and trade pathways of imported invertebrates were recorded. Among the 108 imported invertebrate species recorded in this survey, 13 are freshwater species, while the others are marine ones, and most of them were from tropical zones. Through the assessments of invasive potential including the imported amount, the similarity of the native geographic regions to Taiwan, and its invasion record, three species from the class Anthozoa (Cribrinopsis crassa, Condylactis passiflora, and Alcyonium palmatum), one from the class Scyphozoa (Phyllorhiza punctata), three from the order Decapoda (Procambarus clarkia, Cherax destructor, and Neocaridina sp.), one from the class Bivalvia (Lima scabra), and two from the class Gastropoda (Pomacea bridge and Indoplanorbis exustus) were regarded as having high invasive potentials.
