Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 8 - 9; Rückenflossenweichstrahlen (insgesamt) : 28 - 38; Afterflossenstacheln: 1 - 2; Afterflossenweichstrahlen: 22 - 33; Wirbelzahl: 23 - 25. Small specimens may have an additional forward-directed spine at first dorsal origin (embedded in larger specimens).

Adults are often found offshore, up to 500 miles from the coast (Ref. 9283). They form large schools (Ref. 2850). Young frequently occur in school near kelp and under piers (Ref. 2850). They feed mainly on small crustaceans and fish larvae (Ref. 9283). Large individuals often move inshore and north in the summer (Ref. 2850). Marketed fresh, smoked, canned and frozen; eaten fried, broiled and baked (Ref. 9988).

Estimates based on models

Preferred temperature (Ref. 115969): 7 - 16.2, mean 9.2 (based on 50 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00587 - 0.01627), b=2.96 (2.82 - 3.10), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.2 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (K=0.09-0.21;tm=2-3; tmax=30; Fec<50,000).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (38 of 100).

Preiskategorie (Ref. 80766): Low.
