Etymology: Trachinotus: Greek, trachys, -eia, -ys = rough + Greek,noton = back (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; benthopelagic; oceanodromous (Ref. 51243); depth range 1 - 70 m (Ref. 9626). Subtropical; 43°N - 38°S, 97°W - 35°W (Ref. 44847)
Western Atlantic: Massachusetts, USA through the Gulf of Mexico and scattered localities in the West Indies (Ref. 26938) to Brazil. Also found in Argentina (Ref. 44847). Absent from clear waters of Bahamas and similar islands (Ref. 7251).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 25 - ? cm
Max length : 64.0 cm TL male/unsexed; (Ref. 7251); common length : 40.0 cm TL male/unsexed; (Ref. 5217); max. published weight: 3.8 kg (Ref. 40637)
Adults occur in coastal waters, commonly entering bays and estuaries. Juveniles found in sandy beaches exposed to wave action (Ref. 5217). Adults are absent from insular areas with coralline habitats (Ref. 5217). They generally form small to large schools. They feed on mollusks, crustaceans and other invertebrates and small fish. Excellent food fish (Ref. 9626). Highest priced marine food fish in the USA (Ref. 171). Have been reared in captivity (Ref. 35420).
