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.

Descrição breve Chaves de identificação | Morfologia | Morfometria

Vértebras: 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. 123201): 2.5 - 23.3, mean 17 °C (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).

Nível Trófico (Ref. 69278): 3.6 ±0.51 se; based on food items.

Generation time: 15.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (K=0.07).

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

Categoria de preço (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 32.7 [19.9, 65.7] mg/100g; Iron = 0.741 [0.434, 1.157] mg/100g; Protein = 19.5 [17.7, 21.4] %; Omega3 = 0.35 [0.19, 0.67] g/100g; Selenium = 55.1 [28.6, 103.5] μg/100g; VitaminA = 8.74 [1.85, 42.36] μg/100g; Zinc = 0.685 [0.498, 0.991] mg/100g (wet weight); based on nutrient studies.
