Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 12 - 14; Anal spines: 3; Anal soft rays: 10. Body dusky pink above, silvery below; paired fins pale (Ref. 4181). Body deep, oval. Scales deciduous, spinules minute, margins usually entire (Ref. 37108).

This species is reported to be pelagic in Maul, 1990 (Ref. 3583); however, Schneider, 1990 (Ref. 2683) indicates the species is demersal. Found over muddy bottom (Ref. 26999).

Estimates based on models

Preferred temperature (Ref. 115969): 4.5 - 15.9, mean 10.3 (based on 1342 cells).

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

Bayesian length-weight: a=0.01122 (0.00830 - 0.01517), b=3.05 (2.96 - 3.14), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.53 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.11; tmax=11).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (67 of 100).

Climate Vulnerability (Ref. 125649): Low vulnerability (7 of 100).
