Ecología
marino; agua dulce; salobre demersal; catadromo (Ref. 138280); rango de profundidad 1 - 400 m (Ref. 6898). Subtropical; 4°C - 27°C (Ref. 12468); 46°N - 15°N, 105°E - 170°E
Asia: Japan to the East China Sea, Taiwan, Korea, China and northern Philippines. Spawning grounds of this species are presumed to be in the western Mariana Islands, at a salinity front near 15°N and 140°E (Ref. 54488). Most expensive food fish in Japan. Introduced elsewhere.
Tamaño / Peso / Edad
Madurez: Lm ? range ? - ? cm
Max length : 150 cm TL macho / no sexado; (Ref. 9828); common length : 40.0 cm SL macho / no sexado; (Ref. 35840); peso máximo publicado: 1.9 kg (Ref. 82795)
Vértebra: 114 - 118. Plain-colored.
Body shape (shape guide): eel-like.
Spawning occurs in the sea; small eels ascend the rivers in schools; develop and grow in freshwater. The species may crawl over land at night from one place to another (Ref. 5258, 11230). Adults feed on crustaceans, insects and fish (Ref. 5258). Maximum weight given (1889 g) has a maximum length of 100.8 cm TL in Ref. 82795. Utilized fresh, smoked, canned and frozen; eaten steamed, broiled and baked (Ref. 9988). Used in Chinese medicine (Ref. 12166).
