Etymology: Caranx: French, carangue, the name of a Caribbean fish; 1836 (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; depth range 10 - 188 m (Ref. 58302). Tropical; 26°C - 29°C; 35°N - 37°S, 19°E - 129°W
Indo-Pacific: Red Sea and east coast of Africa to the Hawaiian and Marquesan islands, north to southern Japan (Ref. 559) and the Ogasawara Islands, south to northern Australia. Hybrid with Caranx melampygus found in Hawaii (Ref. 58422).
Length at first maturity / Size / Weight / Age
Maturity: Lm 60.0  range ? - ? cm
Max length : 170 cm TL male/unsexed; (Ref. 9710); common length : 100.0 cm TL male/unsexed; (Ref. 5213); max. published weight: 80.0 kg (Ref. 4795)
soft rays: 15 - 17;
Vertebrae: 24. This species is distinguished by the following characters: gill rakers (including rudiments) 5-7 + 15-17 = 20-24; breast naked ventrally, typically with a small to large patch of prepelvic scales; colour in life of adults, head and body silvery grey to black above, usually paler below; fins usually uniformly grey to black, fish from turbid coastal waters often with yellow fins, the anal fin usually brightest (Ref. 9894).
Pelagic over sand and rock (Ref. 58302). Adults occur singly and inhabit clear lagoon and seaward reefs (Ref. 9710). They feed on crustaceans (like crabs and spiny lobsters) and fishes at night (Ref. 4887). Large individuals may be ciguatoxic. The largest trevally, reaching 1.7 m in length and a weight of over 60 kg (Ref. 48635). Spawning occurs on shallow seaward reefs and offshore banks (Ref. 37816). Juveniles are found in estuaries. Sold mostly fresh and dried salted.
