Short description Identification keys | Morphology | Morphometrics

This species is distinguished from its congeners by the following characters: gill rakers on the first and second gill arches 31-36 rarely 37, on first gill arch only 14-18 rakers; osseous medial groove absent; fleshy medial groove of neurocranium conspicuous or inconspicuous, but never surpassing posterior margin of eyes; lateral margin of sphenotic straight, as wide anteriorly as medially; pterotic lateral margin markedly convex, sometimes angled; mouth 10.5-13.2% SL; cephalic shield at frontals area 8.8-10.1% SL; mesethmoid median portion narrow; mesethmoid medial notch narrow and deep; longer pectoral-fin spine 18.2-22.6% SL; external posterior branch of lateral ethmoid columnar and thin; fenestra delimited by mesethmoid and lateral ethmoid conspicuous (Ref. 116660).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00384 - 0.01719), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (25 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 152 [81, 315] mg/100g; Iron = 1.17 [0.76, 2.00] mg/100g; Protein = 17.2 [15.6, 19.1] %; Omega3 = 0.252 [0.145, 0.441] g/100g; Selenium = 40.9 [22.8, 77.7] μg/100g; VitaminA = 22.9 [10.2, 51.3] μg/100g; Zinc = 1.55 [1.06, 2.32] mg/100g (wet weight);
