Some problems exist with this species' status or catch methods, or information is insufficient for evaluating. Tuna, Yellowfin (Maguro) – Pacific, Pole, Troll & Handline These fish contain levels of mercury or PCBs that may pose a health risk to adults and children.

Yellowfin Tuna grow quickly, produce millions of eggs per spawning, and live up to 9 years. They are found throughout the world’s tropical and sub-tropical oceans. Yellowfin tuna are at a healthy abundance in the Western Pacific, but are depleted in the Eastern Pacific. However, fishing levels on Yellowfin in the Eastern Pacific are sustainable and should allow for its recovery.

Fishing with pole and line, troll, or handline gear is highly selective, resulting in minimal catches of non-target species. However, in the Pacific, Yellowfin Tuna are caught along with depleted Bigeye Tuna. These fishing methods cause little to no damage to bottom habitats.
