The World Depends on Tuna

According to the UN, a large number of countries worldwide depend on tuna for both food security and nutrition.

At the same time, more than 80 countries have tuna fisheries, and their capacity is constantly growing.

Overfishing Threatens Tuna

In recent years, environmental groups like the World Wildlife Fund (WWF) have warned that some types of tuna, such as the bluefin, are now endangered. Because of overfishing, bluefin stocks in the Northern Pacific Ocean have declined by more than 96% in comparison to unfished levels, a 2013 stock assessment showed.

Promoting Sustainable Tuna Fishing

With so many countries around the world relying on tuna for both its nutritional and economic value, World Tuna Day, first observed on May 2, 2017, is an effort to stress the importance of a stable and healthy tuna population.

In practice, the event aims to spread information about the possible impact of drastically declining tuna stocks and to highlight the economic and social benefits of establishing more sustainable fishing practices.
