Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 23 - 28. Body somewhat compressed, slender. Snout less than eye diameter; maxilla long, tip pointed, reaching almost to gill opening; gill cover canals of walkeri-type. Anal fin rather long, its origin before midpoint of dorsal fin base. A pair of narrow dark lines along back, from occiput to tail; a silver stripe along flank, less than eye diameter.
Apparently entirely freshwater and presumably schooling. More data needed.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00234 - 0.01125), b=3.14 (2.97 - 3.31), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
