Maturity: L_m 44.9 range ? - ? cm
Max length : 72.0 cm TL mâle / non sexé; (Ref. 4883); common length : 50.0 cm TL mâle / non sexé; (Ref. 2805); poids max. publié: 3.7 kg (Ref. 4883)

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 Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

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).
