从日本亚热带奄美大岛的三条小河中采集了8条银相雄性印度太平洋鳗鱼（Anguilla marmorata），对其形态学和性腺组织学特征进行了研究。银鳗全长543.8 ± 49.3（496-659）mm，体质量376.0 ± 116.0（282-660）g，年龄14.6 ± 2.3（11-19）岁。与黄鳗相比，银鳗的镀银相关特征（眼睛指数、胸鳍指数、肠体指数）和生殖特征（性腺指数、组织学阶段）显著提前，这与其他鳗类物种相似。
Eight silver‐phase male Indo‐Pacific eels (giant mottled eels)Anguilla marmoratawere collected from three small rivers on subtropical Amami‐Oshima Island, Japan, and their morphological and gonadal‐histological characteristics were examined. The total length, body mass and age of the silver eels were 543.8 ± 49.3 (496–659) mm, 376.0 ± 116.0 (282–660) g and 14.6 ± 2.3 (11–19) years old, respectively. The silvering‐related characteristics (eye index, pectoral‐fin index, gut‐somatic index) and reproductive characteristics (gonadosomatic index, histological stage) of the silver eels were significantly advanced compared to those of yellow eels, which is similar to other anguillid species.
