Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 14 - 16; Anal spines: 1; Anal soft rays: 8; Vertebrae: 28 - 29. This species is distinguished by the following characters: gill rakers on first gill arch 14-16; suborbital bone width is significantly larger than eye diameter; total vertebrae 28-29 (abdominal 12); haemal arch of first causal vertebra without spurs; D III,14-15; A I,8: P 15; V I,7; with ventral fin starting behind vertical line of posterior margin of pectoral fin basement; anal fin begins under third-fourth rays of the dorsal fin from its end; absence of black dotted pigment spots on either head or body (Ref. 117121).

Estimates based on models

Preferred temperature (Ref. 123201): 2.4 - 23, mean 12.5 °C (based on 64 cells).

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

Bayesian length-weight: a=0.01072 (0.00442 - 0.02595), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
