Short description Morfología | Morfometría

Radios blandos dorsales (total): 10-13. This species is distinguished by the following characters: pelvic fin rays 12-14 (usually 13-14); pectoral fin rays 14-17; projecting snout, 20-25% HL; short barbel, 4-5% HL, does not reach vertical through anterior margin of orbit; moderate orbit diameter, 28-35% HL; infraorbital width 12-15% HL; moderately long preopercular supporter, with angle at rear margin, 5-6% HL; 23-28 gill rakers; ventral striae reaching to ½ to ? distance from pelvic fin bases to periproct; otolith has moderately high predorsal lobe, with colliculi separated, closely placed across collum, terminating at some distance from anterior and posterior rims of otolith; otolith length to height (OL:OH), 1.05; total colliculum length to pseudocolliculum length (TCL:PCL), 2.6-2.8 (Ref. 98298).

Estimates based on models

Preferred temperature (Ref. 123201): 7.1 - 13.9, mean 9.5 °C (based on 83 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00145 (0.00087 - 0.00240), b=3.20 (3.05 - 3.35), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nivel trófico (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).
