Comments: Recorded from northern Taiwan (including Tung-hsiao, Tai-chung, and Chang-hwa) (Ref. 43515); collected from mangrove creeks in Chu-Wei and Chu-Nan (Ref. 48455). Also known from the Penghu Islands (Ref. 43515, 55073). In rivers, populations have significantly decreased in the past decade (Ref. 54416). A gradual decrease in allelic diversity has also been reported (Ref. 54416). Taiwan presently dominates aquaculture production (Ref. 9988). Also Ref. 11230, 36073.

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.

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Wirbelzahl: 114 - 118. Plain-colored.

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).

Estimates based on models

Preferred temperature (Ref. 115969): 2.5 - 23.3, mean 17 (based on 432 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00062 (0.00039 - 0.00099), b=3.18 (3.05 - 3.31), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.51 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (K=0.07).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (71 of 100).
