Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 14.0, range 12 - 16 cm
Max length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 556); common length : 15.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 556); 最大体重: 250.00 g (Ref. 556); 最大年龄: 15 年 (Ref. 59043)
背棘 (总数) : 17 - 19. Distinguished from its congeners by having unique characters of 3 discontinuous dark stripes along flank and 55-62 + 4-5 scales along lateral line. Differs further from other species of the genus by having 17-19 dorsal spines (Ref. 59043).
Adults occur in groups in open sand and mud bottom of large rivers with moderate current. Nocturnal, feeding on small invertebrates, especially molluscs, usually crepuscular but may also feed at daytime. Larvae are benthic (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00476 - 0.02414), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.4 ±0.43 se; based on food items.
Generation time: 5.5 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回复力 (Ref.
120179): 低的, 最小族群倍增时间4.5 - 14 年 (tm=2-3; tmax=15).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (42 of 100).
