Abstract

A species of Gyrodactylus collected from 2 species of anguillid eels (Anguilla australis Richardson, 1841 and Anguilla reinhardtii Steindachner, 1867) from Australia is identified as Gyrodactylus anguillae Ergens, 1960. The morphology of sclerites of G. anguillae specimens from Australia is in accordance with previous descriptions of specimens collected from A. anguilla (Linnaeus, 1758) from Europe and A. anguilla imported into Japan. Gyrodactylus anguillae was previously thought to be a parasite specific to A. anguilla, an eel that is native to freshwater catchments throughout Europe. Information on eel translocations and host and parasite biology is reviewed and it is hypothesized that G. anguillae is a naturally occurring parasite in Australia and not an introduction.

摘要

从澳大利亚的2种鳗鲡（澳洲鳗鲡，Richardson于1841年命名；及新西兰长鳍鳗，Steindachner于1867年命名）采集到的一种三代虫被鉴定为鳗三代虫（Ergens于1960年命名）。来自澳大利亚的鳗三代虫标本的硬体形态与之前从欧洲的欧洲鳗鲡（Linnaeus于1758年命名）及引入日本的欧洲鳗鲡采集的标本描述一致。鳗三代虫之前被认为是欧洲鳗鲡特有的寄生虫，欧洲鳗鲡原产于欧洲各地的淡水流域。本文综述了鳗鲡迁移以及宿主和寄生虫生物学的相关信息，并推测鳗三代虫在澳大利亚是一种自然存在的寄生虫，而非外来引入。
