Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 19 - 21; Radios blandos dorsales (total) : 11 - 13; Espinas anales: 1; Radios blandos anales: 10 - 12; Vértebra: 35. Body elongate and strongly compressed. Lateral line single, running close to the upper contour of the body below most of the first dorsal-fin base then abruptly curving ventrally. Body is dark blue, slightly paler on belly; first dorsal fin membrane black (Ref. 6181).
Body shape (shape guide): elongated; Cross section: compressed.
Inhabit continental shelves or around islands. Feed on pelagic crustaceans (Euphausia, Nyctiphanes), cephalopods and fishes (Ref. 6181) like anchovy and pilchard (Ref. 36731). Form schools near the bottom or midwater; sometimes even at the surface at night (Ref. 6181). Prefers temperature between 13° and 18°C (Ref. 36731). Marketed fresh, smoked, canned and frozen; eaten fried, broiled, microwaved and baked (Ref. 9988). Good for fish and chips or smoking; also made into fillet or fish cake in Japan (Ref. 6181). Commonly called as Baracoutta and because it is a fast predator, several English vessels were named after it. In the UK during WW II, this canned fish was commonly eaten that many older people have an aversion to it (D. Parkyn, pers. comm. 05/2022).
Spawning patterns are complex, with different stock spawning at different times of the year (Ref. 6390).
