Migration
Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.

Justification
This species is widespread in continental south and southeast Asia. It is not a common species, and is of major commercial importance in only some parts of its range. It is listed as Least Concern. More data is needed on this species biology, species specific landings and catch effort throughout its range, especially as this species is considered rare and the impact of fisheries on its population is not known and as landing data is often mixed with other Scomberomorus species.

Conservation Actions
Conservation Actions
There are no species specific conservation measures for this species. Recommended research includes more information on catch landings and effort for this species. More research is needed on this species biology, this is one of the least known Scomberomorus species because it has been confused with other species and is not common.
