Madurez: Lm 30.4  range ? - ? cm
Max length : 95.0 cm TL macho / no sexado; (Ref. 1371); common length : 50.0 cm TL macho / no sexado; (Ref. 1371); common length :60 cm TL (female); edad máxima reportada: 6 años (Ref. 83871)
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 43 - 52; Espinas anales: 0; Radios blandos anales: 36 - 41; Vértebra: 50 - 53. Gill rakers short and thick with blunt tips. Pectoral fins relatively short, not reaching level of anal fin origin. Color is silvery with golden luster on back, silvery white on belly (Ref. 1371).
Body shape (shape guide): elongated; Cross section: oval.
Adults inhabit continental shelf depths mainly between 100 and 200 m (Ref. 1371). Larger individuals feed on fish (anchovies, hake, nototheniids, myctophids and Southern blue whitings), squids and macrozooplankton (euphausiids and amphipods); smaller individuals feed on mysids and amphipods (Ref. 1371). Migrate inshore during spring and summer, and offshore into deep water wintering areas after spawning; also undertake diel vertical migrations (Ref. 1371). Sold fresh and frozen.
An indeterminate batch spawner.
