Abundance of Yellowfin Tuna varies among populations, but overall abundance is at a medium level.

Generally captured by purse-seine fisheries for the canned tuna market, Yellowfin Tuna are also captured in pole and troll fisheries, which produce little to no bycatch and are a model for selective fisheries.
