Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Carangidae (Jacks and pompanos) > Caranginae
Etymology: Trachurus: Greek, trachys, -eia, -ys = rough + Greek, oura = tail (Ref. 45335); symmetricus: From symmetricus which means regularly formed - referring to the rough tail (Ref. 6885).

Eastern Pacific: southeastern Alaska to southern Baja California, Mexico and the Gulf of California; reported from Acapulco in Mexico and the Galapagos Islands.

Size / Weight / Age

Maturity: L_m ? range ? - 31 cm
Max length : 81.0 cm TL male/unsexed; (Ref. 2850); common length : 55.0 cm TL male/unsexed; (Ref. 9283); max. reported age: 30 years (Ref. 766)

Short description Morphology | Morphometrics

Dorsal spines (total): 8 - 9; Dorsal soft rays (total): 28-38; Anal spines: 1-2; Anal soft rays: 22 - 33; Vertebrae: 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 of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00600 - 0.01591), b=2.95 (2.81 - 3.09), 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.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (K=0.09-0.21;tm=2-3; tmax=30; Fec<50,000).

Prior r = 0.37, 2 SD range = 0.17 - 0.81, log(r) = -0.99, SD log(r) = 0.4, Based on: 1 M, 2 K, 1 tgen, 1 tmax, 1 Fec records

Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100) .

Price category (Ref. 80766): Low.
