Etymology: Sarda: Latin and Greek, sarda = sardine; name related to the island of Sardinia (Ref. 45335); chiliensis: Named after Chile, South America (Ref. 6885). More on author: Cuvier.
Issue on validity of subspecies: subspecies considered as valid in FB, elevated to species rank as Sarda chiliensis (Cuvier, 1832) in Eschmeyer (CofF ver. May 2011: Ref. 86870).
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; oceanodromous (Ref. 51243); depth range 0 - 100 m. Subtropical; 60°N - 37°S, 149°W - 70°W (Ref. 168)
Southeast Pacific: northern Peru to Talcahuano, Chile (Ref. 9340). The northern subspecies Sarda chiliensis lineolata occurs from off the coast of Alaska, southward to Cabo San Lucas at the tip of Baja California, and in the Revillagigedo Islands.
Length at first maturity / Size / Weight / Age
Maturity: Lm 47.0  range ? - ? cm
Max length : 102 cm TL male/unsexed; (Ref. 9015); max. published weight: 11.3 kg (Ref. 168)
(total): 17 - 19;
soft rays: 12 - 15;
Vertebrae: 42 - 46. Mouth moderately large. Laminae of olfactory rosette 21 to 39. Interpelvic process small and bifid. Swim bladder absent. Spleen large and prominent in ventral view. Liver with elongate left and right lobes and a short middle lobe. Body completely covered with very small scales posterior to the corselet.
A coastal species that reaches sexual maturity at two years of age (Ref. 9340). Older individuals are encountered farther from the coast as compared to the juveniles (Ref. 9340). Spawning is discontinuous and a female of 3 kg may produce millions of eggs per season (Ref. 9340). Forms schools by size. Feeds on a variety of small schooling fishes, squids and shrimps. This species is important to the recreational hook and line fishery operating from private and party boats, piers and jetties, and from the shore. Also caught with encircling nets (Ref. 9340). Utilized fresh, canned and frozen; eaten broiled and baked (Ref. 9988).
