Biology

The Australian Bonito generally schools by size class, but schools forming during the spawning season may contain a range of year classes. Spawns from January to April, during which months the "Bonito run" occurs in inshore waters of the Sydney and South Coast regions.

Fisheries

The commercial catch of between 150 to 200 tonnes per annum is mainly taken by trolling and long-lining. The recreational catch is estimated to be around 80 tonnes per annum. The species is used both as a food fish and as bait for gamefishing.

Conservation

None.

Etymology

The specific name australis is from Latin meaning "southern" in reference to its distribution.
