Length at first maturity / Size / Vikt / Age
Maturity: Lm 40.5, range 39 - 42 cm
Max length : 70.0 cm TL hane/ej könsbestämd; (Ref. 9283); common length : 45.0 cm FL hane/ej könsbestämd; (Ref. 9283); rapporterad maxålder: 16 år (Ref. 26956)
Taggstrålar i ryggfenan (totalt): 9; Mjukstrålar i ryggfenan (totalt): 31-35; Taggstrålar i analfenan 3; Mjukstrålar i analfenan: 27 - 29. Body elongated and little compressed; teeth small and uniseriate; lower branch of first gill arch with 42 to 45 gill rakers; edge of shoulders girdle (cleithrum) with a small furrow at its upper end but lacking papillae; lateral line completely scaled, the scales becoming large scutes posteriorly; scutes in the area of the median curve 1.1 to 1.6 times the diameter of the eye; nape and back metallic blue or dark gray; flanks and belly pale; dorsal edge of operculum with a black stain (Ref. 55763). Body elongate and slightly compressed. Body dark blue dorsally, silvery-white ventrally. Black spot on upper posterior margin of opercle. Fins dusky (Ref. 37339). Pectoral fin falcate and very long (Ref. 27363).
Adults are found in the shore and open oceanic waters, in schools. They feed mainly on fish larvae and small crustaceans. Marketed fresh (Ref. 9283). Utilized canned for human consumption and also made into fishmeal (Ref. 9988). The species is often found in Juan Fernández Is. as an incidental catch of Pseudocaranx chilensis (Guichenot, 1848) fisheries (Ref. 89357).
