摘要

本文報係導筆者於1979年6月至1987年7月間於蘭嶼之椰油、開元港、五孔洞、朗島、東清、野銀、紅頭、機場等地附近海域利用水肺潛水所調查到的47科125屬，352種亞潮帶魚類。其中以隆頭魚科的57種最多，其次是雀鯛科的49種，蝶魚科的27種，粗皮鯛科的22種，與(魚尉)科的20種。蘭嶼之亞潮帶魚類羣聚構造隨各調查地點底質狀況與距離遠近而異。大致而言，以蘭嶼西岸之椰油、開元港一帶魚種最多也最繁茂；北岸之朗島及五孔洞次之；東岸之東清及野銀最少；而西南岸之紅頭魚相則介於東清與椰油之間。

This paper reports a total number of 47 families, 125 genera and 352 speceis of subtidal fishes which were observed or collected from nine different sites around Lanyu by SCUBA diving during June 1979 to July 1987. Among these fishes, the Labridae was the largest family which consisted of 57 species; Pomacentridae which comprised 49 species was the next; the following large families were Chaetodontidae of 27 species, Acanthuridae of 22 speceis, and Blennidae of 20 species. The fish community structures of different investigated sites were various depending upon their substratum types or geographical distances among localities. In general, Yeiu, Kaiyunkang, and up-Kaiyun on the west coast of Lanyu had the most numerous and abundant fishes species, Lantao and Wukungtung on north coast were the next, Tungchin and Yeiying on east side had the least fish species. The fish fauna at Hongton which located on south-western side was in the middle between Tungchin and Yeiu.
