Épines dorsales (Total) : 9 - 10; Rayons mous dorsaux (Total) : 25 - 28; Épines anales: 3; Rayons mous anaux: 28 - 31. Caudal fin broadly forked (Ref. 6885). Generally silvery overlaid lightly with a brassy cast; light green above; sides with a series of about 9 to 11 narrow vertical dark bars, posteriorly, broken and staggered along the lateral line; caudal and anal fins red (Ref. 6885).

Estimates based on models

Preferred temperature (Ref. 123201): 10.3 - 14, mean 12.1 °C (based on 57 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01445 (0.00872 - 0.02396), b=3.00 (2.85 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.5 se; based on diet studies.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (tm=3; tmax=9; Fec=39).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (31 of 100).

Catégorie de prix (Ref. 80766): Unknown.
