Found in coastal areas and oceanic waters; off kelp beds and rocky areas (Ref. 2850). Form large offshore shoals.In Australia, juvenile yellowtail kingfish less than 30 cm FL often occurs near floating objects offshore. Tagging studies (Ref. 27112, 27869) have shown that yellowtail kingfish up to 75 cm FL remain in a limited area, at least for 12 months (Ref. 27112), with most recaptured within 50 km of their release point. Tagging data have also shown that larger fish travel further, with fish tagged off New South Wales being recaptured off Victoria, Lord Howe Island and New Zealand (Ref. 27869).Yellowtail kingfish are opportunistic daytime feeders. Feeding schools will sometimes rise to the surface (Ref. 27112).
