Eastern Central Pacific: La Jolla in southern California, USA to the Galapagos Islands and Paita, Peru. Recently reported from Antofagasta, Chile. Many authors have erroneously considered this species to be a synonym of Scomberomorus maculatus, or a subspecies of it.

Biology     Glossary (e.g. epibenthic)

A schooling species believed to spawn close to the coast over most of its range. Adults occur near the surface of coastal waters to over bottom of the continental shelf (Ref. 11035). Adults feed on small fishes, particularly anchovies (Anchoa and Cetengraulis) and clupeids (Odontognathus and Opisthonema). The most abundant game fish along the Pacific coasts of Mexico and Central America. An excellent food fish enough to support a commercial fishery. Marketed fresh and frozen; also used for ceviche (Ref. 9987).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00366 - 0.01193), b=2.98 (2.83 - 3.13), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.8 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100) .
Price category (Ref. 80766):   Medium.
