Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 10 - 15; Dorsale zachte stralen (totaal) : 11 - 15; Anale stekels: 0; Anale zachte stralen: 11 - 15; Wervels: 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).

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).
