Tuna is one of the world’s most popular seafoods and one of the most economically valuable. In some countries tuna is the main source of protein. Many livelihoods, particularly in island nations, depend on tuna fishing.
In 2021/22 the total global MSC certified sustainable tuna catch reached a record of nearly 2 million tonnes, compared to less than 1 million tonnes in 2017/18.
Here we celebrate the popular and versatile fish and give you everything you need to know about tuna.
