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).

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).
身体斑点不存在于成鱼。 延长的身体有些微中凸的背面轮廓。 头长长度超过体高。 吻的长度远长过眼眶后的头长。 唇发展良好的, 下唇的侧叶宽而厚的, 与摺层，中动脉突起小的。 触须长度些微厚, 比较短的或等于眼直径。 背棘强的, HL 中的 2/3。 超过尾鳍基底的吻尖附近的背鳍起点。 鳃耙超过 15.(参考文献 38453) 臀鳍有 61/2 分支条; 最后的单一背鳍鳍条钙化了, 像棘一样的.(参考文献 43281)
Omnivorous, feeding mainly on benthic invertebrates (Ref. 41299). Females are larger than males (Ref. 1441).
雌性是大于雄性。 (参考文献 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 (0.00586 - 0.00855), b=3.10 (3.05 - 3.15), in cm total length, based on LWR estimates for this species (Ref.
93245).
营养阶层 (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.
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (tm=3-4; k=0.16-0.19).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (55 of 100).
