Asia: throughout the Amur basin (Ref. 1441); eastern Asia from the Amur basin to northern Vietnam, Japan and islands of Hainan and Taiwan (Ref. 26334). Recorded from Mekong basin in Laos which apparently the result of introduction, either in Laos, or more likely upriver in Mekong basin in China (Ref. 37786).

Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 30.5, range 29 - 32 cm
Max length : 67.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 126870); common length : 33.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 1441); common length :40.6 cm TL (female); 最大體重: 3.0 kg (Ref. 56557); 最大年齡: 15 年 (Ref. 56557)
脊椎骨: 40 - 42. Body spots absent in adults. Elongated body with slightly convex dorsal profile. Head length longer than body depth. Snout length much longer than postorbital head length. Lips well developed, lateral lobes of lower lip broad and thick, with folds, the median process small. Barbel length slightly thick, shorter or equal to eye diameter. Dorsal spine strong, 2/3 of HL. Origin of dorsal fin nearer the tip of snout than the caudal base. Gill rakers more than 15 (Ref. 38453). Anal fin with 6 1/2 branched rays; last simple dorsal rays ossified, spine-like (Ref. 43281).
身體斑點不存在於成魚。 延長的身體有些微中凸的背面輪廓。 頭長長度超過體高。 吻的長度遠長過眼眶後的頭長。 唇發展良好的, 下唇的側葉寬而厚的, 與摺層，中動脈突起小的。 觸鬚長度些微厚, 比較短的或等於眼直徑。 背棘強的, HL 中的 2/3。 超過尾鰭基底的吻尖附近的背鰭起點。 鰓耙超過 15.(參考文獻 38453) 臀鰭有 61/2 分支條; 最後的單一背鰭鰭條鈣化了, 像棘一樣的.(參考文獻 43281)
Omnivorous, feeding mainly on benthic invertebrates (Ref. 41299). Females are larger than males (Ref. 1441).
雌性是大於雄性。 (參考文獻 1441)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00588 - 0.00853), b=3.10 (3.05 - 3.15), in cm total length, based on LWR estimates for this species (Ref.
93245).
營養階層 (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
Generation time: 6.6 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回復力 (Ref.
120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (tm=3-4; k=0.16-0.19).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (55 of 100).
