Tuna: Yellowfin

Ahi, Ahi Tuna

Maguro, Toro

The yellowfin is a large tuna, found throughout the world’s tropical open oceans. The four stocks of yellowfin comprise the western and central Pacific, eastern Pacific, Atlantic, and Indian Ocean stocks. Yellowfin matures at an early age, has a moderate lifespan, is highly fecund, and is widely distributed, making it inherently resilient to fishing pressure. However, the various yellowfin fisheries globally vary in their sustainability. The most sustainable of these is the US Atlantic fishery , which catches yellowfin by troll/pole. Troll and pole gear has minimal habitat impacts and bycatch, and the US stock status is a moderate concern. The longline and purse seine fisheries for yellowfin are associated with moderate to critical concerns with bycatch and ecosystem impacts. Yellowfin tuna can also be caught by hand lines (Hawaii). Management of yellowfin tuna is complicated and varies by ocean basin.

Their wide distribution, very rapid sexual maturity, relatively short life, widely-dispersed spawning grounds, and broadcast spawning system make yellowfin tuna inherently resistant to fishing pressure.

The status of yellowfin in the Atlantic is considered a moderate conservation concern due to the uncertainty associated with this stock, as it is approaching an overfished condition and overfishing may be occurring.

Troll caught yellowfin tuna has very little bycatch.

Troll caught yellowfin tuna has no interaction with bottom habitat.

Management of U.S. fisheries in the Atlantic is deemed highly effective due to the adequate enforcement and data collection.
