Short description Identification keys | Morphology | Morphometrics

This species is distinguished by the following characters: pelvic fin rays 11 (rarely 12); pectoral fin rays 13-15; projecting snout, 20-25% HL; no barbel; moderate orbit diameter, 30-33% HL; infraorbital width 13-15% HL; moderately long preopercular supporter, with obtuse angle at rear margin, 3-5% HL; 20-26 gill rakers; ventral striae reaching to ½ distance from pelvic fin bases to periproct; otolith has moderately high predorsal lobe, with colliculi separated, widely placed across collum, terminating at some distance from anterior and posterior rims of otolith; otolith length to height (OL:OH), 1.05-1.1; total colliculum length to pseudocolliculum length (TCL:PCL), 2.4-2.6 (Ref. 98298).

Estimates based on models

Preferred temperature (Ref. 123201): 6.9 - 13, mean 9.3 °C (based on 172 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.40 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
