Tuna, Skipjack – Purse-seine (Katsuo) 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”, with most caught using purse seines. Skipjack Tuna can spawn millions of eggs each year, grow fast, and have a high rate of population increase.

Although management measures are generally weak, Skipjack Tuna are common in the Atlantic, Indian and Pacific Oceans. Bycatch from purse seines is moderate but can include other tunas, dolphins, sharks and sea turtles, thus pole and line caught Skipjack Tuna is a better alternative.
