Etymology: Chloroscombrus: Greek, chloros = green + Greek, skombros = the name of several fishes, a mackerel (Ref. 45335).
Environment / Climate / Range
Marine; brackish; pelagic-neritic; depth range 0 - 55 m (Ref. 26912). Subtropical, preferred 26°C (Ref. 107945); 43°N - 13°S
Western Atlantic: Massachusetts to Florida, USA and Bermuda to Uruguay; throughout Caribbean Sea and Gulf of Mexico (Ref. 9626); Bahamas, Antilles, along Central and South American coasts to Uruguay (Ref. 26938). Eastern Atlantic: Mauritania to Angola (Ref. 57392). Replaced by Chloroscombrus orqueta in eastern Pacific. These two species have not been adequately studied and may prove to be conspecific.
Length at first maturity / Size / Weight / Age
Maturity: Lm 12.4, range 10 - ? cm
Max length : 65.0 cm TL male/unsexed; (Ref. 57392); common length : 25.0 cm TL male/unsexed; (Ref. 5217)
soft rays: 25 - 28. Diagnosis: body compressed and deep (depth comprised from 2.3 to 2.8 times in fork length) (Ref. 57392), its ventral profile distinctly more convex than the dorsal (Ref. 26938, 57392). Snout very short, its tip blunt, upper jaw extending almost to behind level of anterior eye margin; 2 dorsal fins, the first with 8 spines, the second with 1 spine and 25-28 soft rays; anal fin with 2 detached spines, followed by 1 spine and 25-28 soft rays; upper lobe of caudal fin longer than the lower; small, cycloid scales covering most of body, including chest; 5-15 weak scutes on posterior part of lateral line, at level of caudal peduncle, the latter without bilateral keels (Ref. 57392). Metallic blue above, silvery below; caudal peduncle with black saddle spot (Ref. 3197).
Coloration: back greenish or bluish, sides silvery-white; a dark, saddle-shaped blotch on caudal peduncle just before caudal fin, and another at upper angle of gill cover (Ref. 57392).
Adults are found over soft bottoms of the continental shelf; sometimes forming schools near the surface (Ref. 5217). Marine pelagic species very common in coastal lagoons and estuaries (Ref. 57392). They feed on fish, cephalopods, zooplankton and detritus (Ref. 28587). Juveniles common in brackish estuaries and often associated with jellyfish (Ref. 5217). Marketed fresh and salted.
