Week 18: Research Helps Unmask Shifting Vessel Identities in the Global Fishing Fleet

Using multiple data sources, researchers gain new understanding of vessel reflagging and potential unauthorized activity.

The Issue

Every commercial fishing vessel is registered to and flies the flag of a particular State, but it’s not necessarily the State that it originates from. There’s a whole nexus of actors involved in international fishing whereby a vessel can be flagged to one country, its owner(s) reside in another, while operations are carried out in a third nation’s waters. To make matters even more confusing, vessel owners can change a ship’s country of registration—a practice known as reflagging.
