Two Species of Siphonostomatoid Copepods Parasitic on Pelagic Fishes of Taiwan

寄生在台灣產海洋表層魚類的兩種管口目橈足類

摘要


本報告描述兩種屬於管口目的寄生橈足類,它們分別是屬於Caligidae科的Caligus bonito Wilson,1950和屬於Euryphoridae科的Euryphorus nordmanni Milne-Edwards,1840。前者是寄生在採自大溪漁港(位於台灣東北海岸)的齒鰆【Sarda orientalis (Temminck & Schlegel)】,而後者是寄生在採自東石漁港(位於台灣中部西海岸)的鬼頭刀(Coryphaena hippurus Linnaeus)。文中除了討論台灣發現的C.bonito,在兩次不同的採集地與寄生魚種所採到的蟲體形態差異外,也對E.nordmanni的雌雄成虫及未成熟雌虫加以描述。

Two species of siphonostomatoid copepods belonging, respectively, to Caligidae and Euryphoridae are reported. They are: Caligus bonito Wilson, 1905 from striped bonito, Sarda orientalis (Temminck et Schelegel), landed at Dah-Hsi Fishing Port (on the northeast coast of Taiwan) and Euryphorus nordmanni Milne-Edwards, 1840 from the common dolfinfish, Coryphaena hippurus Linnaeus, landed at Dong-Shih Fishing Port (on the central west coast of Taiwan). Some morphological differences of C. bonito found from two different occasions in Taiwan are discussed. A juvenile female of E. nordmanni is described in addition to the mature adults of both sexes.
