An ecological study of the Kidako morayGymnothorax kidako(Anguilliformes, Muraenidae) was conducted at Tateyama Bay, Chiba, Japan. Although this species is common along temperate coasts and is distributed as a food in local cities of southern Japan, its reproductive ecology, age structure, and growth rates are unknown. Specimens (in total, 93 males and 117 females) were collected monthly from January to December 2015, and in May 2022. There was no significant difference between the total length of males and females. Throughout the year, the male gonadosomatic index was relatively constant, and sperm was detected. The female gonadosomatic index was especially high and tertiary vitellogenic oocytes were observed in the ovary from July to August. A female with a swollen abdomen full of ovulated oocytes was collected in August. Results indicate that spawning inG. kidakoat Tateyama occurs from July to August. Age was estimated from increment analysis of the right sagittal otolith, on which a single annulus forms between July and August. On the basis of otolith-increment counts, 58 males and 83 females were aged 3–34 years. The von Bertalanffy growth formula indicated that males and females grow rapidly over the first 10 years, after which growth slowed for both sexes, but males continued to grow at a greater rate than females.
