生態学
海 pelagic-neritic; 深さの範囲 0 - 500 m (Ref. 54925), usually 100 - 300 m (Ref. 54925). Subtropical; 14°N - 37°S, 17°W - 24°E (Ref. 54925)
Eastern Atlantic: Gambia to Gulf of Guinea to South Africa. Bianchi et. al. 1993 notes 'Smith-Vaniz (1992, pers. comm.) does not believe that Trachurus capensis is a valid species but admits that an adequate series of this species along the coast of Africa are not available'.

Adults are found mainly over the continental shelf, often over sand bottoms (Ref. 27121). Shoals rise to feed in surface waters at night and found close to the bottom during the day (Ref. 27121). Juveniles feed mainly on copepods while adults prey on fish and a wide range of invertebrates (Ref. 27121).
