Tuna is a beautiful and amazing fish. There are over 40 different species, they can live for over 30 years, can grow over 2m long and weigh over 400kg. In summary, they’re large, long-lived, slow breeding, top order predators. 

Unfortunately, due to their popularity as food, tuna populations have been drastically reduced by fishing – some as much as 90%. Although there are many Management plans for tuna, some species of tuna are still being overfished. In fact, Southern Bluefin Tuna, whose migratory route includes Australia, are critically endangered (IUCN Redlist), yet are still being fished.

So what can you do?

The best thing you can do to help tuna is to try and reduce the total amount of tuna you eat, and avoid Southern Bluefin Tuna entirely. For tuna you eat, there are choices that are more sustainable. The Marine Stewardship Council (MSC) certifies fisheries as sustainable. When choosing canned tuna, look for cans with the MSC ecolabel. Another option is to follow Greenpeace’s guide to canned tuna.
