Etymology: Bagre: Mozarabic, bagre, taken from Greek, pagros = a fish (Dentex sp.) (Ref. 45335). More on author: Mitchill.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; depth range 0 - 50 m (Ref. 5217). Subtropical; 43°N - 34°S, 98°W - 34°W
Western Atlantic: coast of Gulf of Mexico, Cuba, western margin of the Caribbean, and the northern margin of South America. Sometimes in rivers and estuaries.
Length at first maturity / Size / Weight / Age
Maturity: Lm 33.0, range 50 - 63.5 cm
Max length : 69.0 cm TL male/unsexed; (Ref. 40637); common length : 50.0 cm TL male/unsexed; (Ref. 3265); max. published weight: 4.4 kg (Ref. 40637)
soft rays: 22 - 28. Maxillary barbels, first ray of dorsal fin, and first ray of pectoral fin extended as long, flat filaments. 1 pair of barbels on chin.
Mainly marine but enters brackish estuaries with relatively high salinities (Ref. 5217). Opportunistic feeders over mud and sandy bottoms (Ref. 27549). Feeds mainly on small fishes and invertebrates. The dorsal and pectoral fins are equipped with a serrated erectile spine, both of which are venomous. Commonly caught by anglers along bridges, piers and catwalks. Flesh considered good; marketed fresh (Ref. 5217). Minimum depth reported taken from Ref. 57178.
Each male carries not more than 50 eggs in its mouth, usually averaging from 15 to 30 (Ref. 205).
