Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 43 - 45. Body rather slender, belly with 24 to 25 + 10 or 11, total 34 to 36 scutes. Eye large, lower jaw projecting. Dorsal fin origin behind midpoint of body; anal fin origin below dorsal fin base. Swim bladder without a posterior tube (or tubes) passing backward into the body muscles. No toothed hypo-maxilla between hind tip of pre-maxilla and blade of maxilla.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00397 - 0.01910), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.5 ±0.5 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.
