Occurs in coastal waters (Ref. 9340) and also in oceanic waters (Ref. 9563). Minimum depth reported at 87 m (Ref. 58489); fishing depths to 265 m (cited in Ref. 58302). Schooling by size which may include jack mackerels and Pacific sardines. They are plankton feeders filtering copepods and other crustaceans, but adults also feed on small fish and squids. Also caught with encircling nets (Ref. 9340). Marketed fresh, dried-salted, smoked, canned and frozen (Ref. 9987).
