The survey of the imported aquatic invertebrates via the live aquarium ornamental trade in Taiwan.

Abstract

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.
