海洋; 淡水; 半鹹淡水 居於水底的; 降海洄游 (Ref. 51243); 深度上下限 1 - 400 m (Ref. 6898). 亞熱帶的; 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.
亞洲: 日本到中國海東部，台灣，韓國，中國與菲律賓北部。 在 15 ° N 與 140 ° E 附近的鹽度前面, 這種的產卵場被推測在西方的馬里亞納群島中。 (參考文獻 54488) 在日本的大多數的貴食用魚。 引入了其他地方。

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).
在海洋產卵; 小的鰻魚上溯到河成群; 發育而且生長在淡水中。 此魚種可能從一個地方到另外的爬行土地之上在晚上。 (參考文獻 5258,11230) 吃甲殼動物，昆蟲與魚。 (參考文獻 5258) 生鮮使用,煙燻了, 罐裝及冷凍; 清蒸, 火烤而且燒烤。 (參考文獻 9988) 被用於中藥材了。 (參考文獻 12166)
