Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 47 - 51. Head rather long. Pectoral fin tips usually reaching origin of anal fin. Caudal fin usually truncate, progressively becoming concave with growth. Color is steel gray to blackish on back, silvery white on sides and belly.

Feeds mainly on small fishes, and to a lesser extent on crustaceans and cephalopods. Undergoes seasonal latitudinal migrations (Ref. 9709). Spawning takes place in northern areas from January to March (Doutre, 1960), and from October to March (López Abellán and Ariz Telleía, 1993). Marketed fresh or frozen (Ref. 58452). Minimum depth reported from Ref. 26999.

Estimates based on models

Preferred temperature (Ref. 115969): 10.2 - 16.8, mean 14.1 (based on 28 cells).

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

Bayesian length-weight: a=0.00501 (0.00308 - 0.00816), b=3.10 (2.95 - 3.25), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.07-0.17).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).

Climate Vulnerability (Ref. 125649): High to very high vulnerability (75 of 100).

Price category (Ref. 80766): High.
