Short description Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 2. This species is distinguished by the following characters: pelvic rays usually 12-14 (elsewhere 11-13); total gill-rakers first arch (outer/inner) 17-22/23-28, second arch 22-28/22-26; no chin barbel; snout length 22-31% HL; orbit diameter 29-40% HL; suborbital width 10-14%HL, interorbital width 24-29%HL; most of the orbit, upper surface of snout, sides of head and trunk silvery or pale, ventral aspects of heed and trunk black; a prominent midlateral stripe of silvery (when fresh) or brownish (preserved) pigment running along trunk and tail (Ref. 97189). Additional distinguishing characteristics: pectoral fin rays 13-16; projecting snout, 20-26% HL; infraorbital width 11-16% HL; moderately long preopercular supporter, with obtuse angle at rear margin, 4-9% HL; ventral striae reaching to ½ distance from pelvic fin bases to periproct; otolith has moderately high predorsal lobe, with colliculi separated, closely placed across collum with a tendency to joining in large individuals, terminating at some distance from anterior and posterior rims of otolith; otolith length to height (OL:OH), 1.1-1.2; total colliculum length to pseudocolliculum length (TCL:PCL), 1.8-2.4 (Ref. 98298).
Body shape (shape guide): elongated.

Estimates based on models
Preferred temperature (Ref. 123201): 6.4 - 11.4, mean 8.2 °C (based on 237 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00214 (0.00109 - 0.00421), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
