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 成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
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).
