Tuna, Yellowfin (Maguro) – Atlantic, Unassociated Purse SeineThese fish contain levels of mercury or PCBs that may pose a health risk to adults and children. Our source of information is http://seafood.edf.org/.  We also recommend that you check local advisories.

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. In the Atlantic Ocean, Yellowfin Tuna are at a low abundance and are considered depleted.

Purse seines that target free schools of tuna and do not use fish aggregating devices (FADs) are called unassociated purse seines.  The unassociated purse seine tuna fisheries in the Atlantic catch depleted bigeye tuna and occasionally endangered/ threatened sea turtles. This fishing method does not contact bottom ocean habitats.
