Illegal, unreported and unregulated (IUU) fishing significantly harms not only fish populations and ocean health but also the people who rely on healthy fisheries for food and livelihoods. To draw attention to these threats, the United Nations in 2017 declared June 5 International Day for the Fight Against IUU Fishing.

To mark the occasion this year, The Pew Charitable Trusts is testing your knowledge of IUU fishing and its effect on the global seafood supply chain and the well-being of millions of people around the world.
