Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 17 - 18; Radios blandos dorsales (total) : 13 - 15; Espinas anales: 1; Radios blandos anales: 15 - 17; Vértebra: 33. Lateral line single, slightly curving anteriorly, then fairly straight and oblique. Body is dark blue with metallic tint (Ref. 6181).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Mesobenthopelagic (Ref. 47377). Inhabits the continental slope (Ref. 6181). Feeds on small fishes (Ref. 6181) and euphausiids (Ref. 47377). Since 1980, no catches have been reported, except for 21 t caught in 1990 by Argentina (Ref. 6181). Good for smoked fish and fish and chips (Ref. 6181).
