IUU fishing
Illegal, unreported and unregulated fishing, which undermines rules meant to keep fish stocks healthy.
Also: illegal fishing, illegal, unreported and unregulated fishing
IUU fishing covers boats fishing without licences or in closed areas, catches that go unreported or are falsely reported, and fishing in waters no one manages. It robs coastal states, often poor ones, of fish and income, and makes stock assessment harder. Some IUU boats are linked to forced labour. The Port State Measures Agreement, in force since 2016, lets countries refuse port entry to suspected boats, and satellite tracking of fishing fleets has made it easier to spot vessels switching off their transponders.
