A can of tuna may be small in size but tuna brands play a big role in the health of our oceans. This role is becoming increasingly important as tuna stocks rapidly decline and thousands of tonnes of other marine animals continue to be killed, pushing some species towards extinction. Globally, we must end our use of destructive fishing methods if we are to reverse the decline of our oceans. Some tuna brands are taking ocean protection seriously and switching to sustainable fishing methods, such as ‘pole and line’, and abandoning the use of FADs with purse seine nets. With pole and line fishing, each fish is individually caught, reducing the impact on tuna stocks and on the level of bycatch.
