Abstract:

A method is described for rearing the offspring of wild-captured Pacific bonito. Six basic stages of post-embryonic development were determined based on ontogenetic changes in morphology and behaviour. Each stage corresponded with a different food source preference, related to the development of new swimming and predatory behaviours. A controlled environment is required to study the processes underlying development of those behaviours adeptly performed by bonito and other scombrids, including high-efficiency swimming and visually guided predation on other advanced species.
