Chloroscombrus chrysurus (Linnaeus 1766)

Diagnostic Description

provided by Fishbase
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).

Trophic Strategy

provided by Fishbase
Found over soft bottoms of the continental shelf; sometimes forming schools near the surface (Ref. 5217). Feeds on fish, cephalopods, zooplankton and detritus (Ref. 28587, 57616). Juveniles common in brackish estuaries (Ref. 5217) and often associated with jellyfish. Larvae feed primarily on cladoceran Penilia avirostris, copepods and nauplii, and the number and size of prey increased with larval development (Ref. 75983). These are the main food item components of the larval diet in spring and summer. Larval feeding incidence was higher during the day and it increases as the larvae grow (Ref. 75983).

Atlantic bumper

provided by wikipedia EN

The Atlantic bumper (Chloroscombrus chrysurus) is a game fish in the family, Carangidae. It was first described by the "father of modern taxonomy", Carl Linnaeus in the book, Systema Naturae. Atlantic bumper are known to eat smaller fish, cephalopods, and zooplankton.[3]

Description

Shoaling Atlantic bumper in an aquarium.

The Atlantic bumper is best recognized by its profile, the bottom being much more curved than the top.[2] Also, the lateral line is arched near the head.[2] Atlantic bumper are generally described as silver to golden colored, with golden yellow on the anal and caudal fins,[4] which have 3 spines, 25-28 rays and 9 spines, 25-28 rays, respectively.[2] There is an obvious black saddle-shaped blotch on the caudal peduncle and a similar patch near the edge of the opercle.[4]

Although the average size of Atlantic bumper is 25 centimetres (9.8 in),[5] the largest recorded Atlantic bumper was 65 centimetres (26 in) long.[6]

Distribution and habitat

In the western Atlantic, Atlantic bumper is found from Massachusetts, to south Brazil.[2] They are known to be found off Bermuda, in the Caribbean, and the Gulf of Mexico.[7] Their range continues south to the coast of Uruguay.[8] In the eastern Atlantic, the Atlantic bumper are known from the coast of Mauritania to Angola.[2] One single record was reported in the Mediterranean Sea off Spain in 1997.[9] They are not found in the eastern Pacific although a visually similar species, Chloroscombrus orqueta, or the Pacific bumper is ranged for that area. Little is known about how these two species relate to each other, and they may represent only one species.[2]

Atlantic bumper caught in Cameroon.

The Atlantic bumper is found in subtropical waters up to 55 m in depth.[2] They usually dwell near soft bottoms of the continental shelf, but have been observed schooling near the surface.[10] While it is primarily a salt water fish, juveniles have been found in brackish estuaries.[10]
