東沙環礁之新紀錄種魚類——雙帶鰺

First record of the rainbow runner Elagatis bipinnulata ( Quoy and Gaimard, 1825 ) (Perciformes: Carangidae) from the Dongsha Atoll

Elagatis bipinnulata, also known as the rainbow runner, is the only member of the genus Elagatis of the Carangidae, a pelagic species with an important role in recreational fisheries. Elagatis bipinnulata is broadly distributed in tropical oceans and abundant around Taiwanese waters, but it has never been reported from Dongsha, a remote atoll located in the northern South China Sea. In this study, we report the first record of E. bipinnulata in Dongsha. Morphological measurements and meristic counts of the specimen are also provided. 雙帶鰺為鰺科帶鰺屬下之唯一物種，為一廣泛分布於全球暖水域的大洋性魚種，也是休閒漁業的重要目標魚。雙帶鰺在臺灣周遭海域頗常見，但迄今未曾紀錄於南海北部的東沙水域。本篇為雙帶鰺在東沙環礁的首筆紀錄，形態描述及形質測量詳細記錄於文中。
