Some problems exist with this species' status or catch methods, or information is insufficient for evaluating. Tuna, Skipjack (Katsuo) – Atlantic, Unassociated Purse Seine These fish contain levels of mercury or PCBs that may pose a health risk to adults and children.

Skipjack Tuna represent about half of the global tuna catch and are commonly sold as ‘canned light’ or ‘chunk light’. They can spawn millions of eggs each year, grow fast, and have a high rate of population increase. In the Atlantic, Skipjack Tuna are at a healthy abundance and fishing levels on this species are sustainable.

Purse Seines are the most common method used to catch Skipjack Tuna. 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 fishery in the Atlantic catches depleted Yellowfin Tuna and occasionally endangered/threatened sea turtles. This fishing method does not contact bottom ocean habitats.
