Yellowfin

Fisheries and Aquaculture Department/UN FAO

Yellowfin (Thunnus albacares) are found in the subtropical and tropical areas of the Atlantic, Indian and Pacific Oceans. Yellowfin’s geographic limits are from 45°-50° N and South, although in the Pacific they occur mainly from 20° N and South. Four stocks are assessed and managed by the RFMOs: Atlantic Ocean, Eastern Pacific, Western Pacific and Indian Ocean.

Yellowfin form both free and associated schools with adults generally forming schools of similarly sized individuals. The free-swimming schools tend to contain large individuals and are mono-specific. In the eastern Pacific, schools are often associated with dolphin pods, an association not common elsewhere.
