Description synthétique Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 10 - 15; Rayons mous dorsaux (Total) : 11 - 15; Épines anales: 0; Rayons mous anaux: 11 - 15; Vertèbres: 39. This species is distinguished by the following characters: medium-sized fish with a robust, elongate and fusiform body; teeth small and conical, in a single series; total gill rakers on first gill arch 29-34; D1 XI-XIV with both dorsal fins separated by only a narrow interspace (not wider than eye), anterior spines of first fin much higher than those midway, giving fin a strongly concave outline; D2 much lower than first and followed by 8-10 finlets; anal fin followed by 6-8 finlets; pectoral fins short, never reaching interspace between dorsal fins; 2 flaps (interpelvic process) between pelvic fins; very slender caudal peduncle with a prominent lateral keel between 2 small keels at base of caudal fin; body naked except for corselet and lateral line. Colour of back dark blue with a complicated striped pattern which does not extend forward beyond middle of first dorsal fin; lower sides and belly silvery white; several characteristic dark spots between pelvic and pectoral fins (but may not always be present) (Ref. 9684, 90102).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Occurs in open waters but always remains close to the shoreline. The young may enter bays and harbors. Forms multi-species schools by size with other scombrid species comprising from 100 to over 5,000 individuals. A highly opportunistic predator feeding indiscriminately on small fishes, especially on clupeoids and atherinids; also on squids, crustaceans and zooplankton. Caught in multispecies fisheries, mainly by surface trolling; also with gill nets. Generally marketed canned and frozen; also utilized dried, salted, smoked and fresh (Ref. 9684).
