 note = {Fishes collected at the rivers of Amamioshima Island in the Ryukyu Islands, during the period from April 1991 to February 1992, were classified into 136 species of 45 families. Of these, the gobiid fishes were dominant, comprising 51 species. Based on the life cycle, the river fishes of this area were divided into four categories with one species of unclassified category : five species of pure fresh-water form ; one of land locked ; 14 of diadromous ; and 115 of periferal. According to seasonal collections during the survey period at five stations of the Yanmagawa River, most of the young sporadic fishes appeared abundantly in summer to autumn, but disappeared in winter to spring. They were thought to use the river for their nursery and feeding grounds., 1991年4月から1992年2月にかけて奄美大島の陸水域で魚類相調査を行い,45科136種の魚類が確認された。奄美大島の陸水域における魚類相の特徴として,ハゼ科魚類が最も優占していること,周縁性淡水魚が大部分を占めることが明らかになった。また,山間川において年4回の採集を行い,魚類相の季節的変化を調査した。殆どの偶来性淡水魚は夏期から秋期の間は河川内に侵入するが,冬期から春期の間は侵入しないことが確認された。特に未成魚において顕著な増減が示されたため,未成魚の育成場および索餌場として利用するために河川内に侵入するものと考えられた。},
