Highly prized for sushi and sashimi, bluefin tuna is the most valuable fish on the planet.

But increased demand and the high prices paid have seen fishing spiral out of control — particularly for Atlantic bluefin tuna in the Mediterranean Sea, the site of most bluefin catches.

Nearly one-third of all catches here come from illegal, unregulated, and unreported (IUU) fishing, most of which is carried out by EU fleets.

The best Atlantic bluefin tuna choice is caught legally and over 30kg in size. However, it is virtually impossible for consumers to know whether tuna has been caught legally or not, or the size of the tuna prior to filleting and processing.

Given the precarious state of stocks and the rampant illegal fishing, it may be best to avoid bluefin tuna, at least until an effective and strict recovery plan for the species is implemented.

Alternatives are skipjack and yellowfin tuna, whose biology (high fecundity and relatively fast growth rates) makes them better able to withstand high levels of fishing.

Tuna caught using pole-and-line methods have little associated bycatch and are the best choice.

Purse seine fisheries for skipjack and yellowfin tuna in the Atlantic also have low levels of bycatch and low interaction with marine turtles and marine mammals.

Say Yes to sustainable seafood

Take a stand against unsustainable fishing and pledge to buy MSC certified seafood

If you can't find seafood with the MSC label in your local store, please ask for them. Businesses do listen to their customers.

If they think there is enough demand for MSC certified seafood they will stock it.
