Etymology: Trachurus: Greek, trachys, -eia, -ys = rough + Greek, oura = tail (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; benthopelagic; depth range 20 - 100 m (Ref. 2683), usually 20 - 100 m (Ref. 54930). Tropical; 15°C - 22°C (Ref. 54930); 35°N - 19°S, 26°W - 14°E (Ref. 54930)
Eastern Atlantic: Morocco to Angola. Sometimes ranging south to northern Namibia (Ref. 27121).
Length at first maturity / Size / Weight / Age
Maturity: Lm 24.1  range ? - ? cm
Max length : 35.0 cm FL male/unsexed; (Ref. 7097); max. published weight: 2.0 kg (Ref. 27584)
Adults are sometimes found near the surface. They form schools (Ref. 2683). Commercial fishing trawlers catch this species at depths up to 650 m (J. Luyben, pers. Comm. 10/02). Adults feed mainly on crustaceans (Ref. 4233). Eggs are pelagic (Ref. 4233).
