Max length : 72.0 cm TL macho / no sexado; (Ref. 4883); common length : 50.0 cm TL macho / no sexado; (Ref. 2805); peso máximo publicado: 3.7 kg (Ref. 4883)

Biología     Glosario (por ej. epibenthic)

Adults feed mostly on fish and krill. Synchronous spawner (Ref. 50743). Larvae have a long pelagic phase (Ref. 71843). Utilized as a food fish (Ref. 4931).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

There is only one generation of oocytes in the ovaries indicative of determinate fecundity (Ref. 50743). Mature females may spawn for the first time from around 6-8 years of age (Ref. 71843).
