Etymology: Auxis: Greek, auxis = a variety of tunna (Ref. 45335).
Eponymy: Dr François-Etienne de la Roche (or Delaroche) (1780–1813) was a Swiss physician, chemist, botanist and ichthyologist, who qualified as a physician in Paris (1808) and worked at the Hospice Necker. [...] (Ref. 128868), visit book page.

背面の脊椎 (合計) : 9 - 12; 背鰭 (合計) : 10 - 13; 肛門の骨: 0; 臀鰭: 12 - 14. Back bluish, turning to deep purple or almost black on head. Scaleless area with pattern of 15 or more fairly broad, nearly vertical dark bars. Belly white. Pectoral and pelvic fins purple, their inner sides black. Body robust, elongate and rounded. Teeth small and conical, in a single series. Pectoral fins short, not reaching vertical line from anterior margin of scaleless area above corselet. A large, single-pointed flap (interpelvic process) between pelvic fins. Body naked except for corselet, which is well developed in its posterior part 9 more than 6 scales wide under second dorsal-fin origin). A strong central keel on each side of caudal-fin base between 2 smaller keels (Ref 9684).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Adults are principally caught in coastal waters and around islands (Ref. 9340). Form schools. Feed on small fishes, particularly anchovies, crustaceans (especially crab and stomatopod larvae) and squids. Eggs and larvae are pelagic (Ref. 6769). Because of their abundance, they are considered an important element of the food web, particularly as forage for other species of commercial interest. Also caught with encircling nets and troll lines (Ref. 9340). Marketed fresh and frozen (Ref. 9340) and also dried or salted, smoked and canned (Ref. 9987).

Fecundity ranges between 31,000 and 103,000 eggs per spawning according to the size of the fish.
