臀鳍软条: 7. Agosia chrysogaster can be distinguished by its elongated lower lobe on anal fin in large female, 70-95 small lateral scales, small barbell at corner of mouth, long coiled intestine, black peritoneum, rounded snout, slightly subterminal mouth, dorsal fin origin above or slightly in front of pelvic fin origin, 7 anal rays, pharyngeal teeth 0,4-4.0. Color consists of dark gray above, dusky black band along silver side enlarged into black spot at caudal fin base, often gold flecks on side. Large male is light yellow below, with yellow paired fin bases, large dorsal fin (Ref. 86798).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
