WASHINGTON, D.C., Jan 19 (Bernama-GLOBE NEWSWIRE) — A new study published today in Science Advances combines a decade’s worth of satellite vessel tracking data with identification information from more than 40 public registries to determine where and when vessels responsible for most of the world’s industrial fishing change their country of registration, a practice known as “reflagging”, and identify hotspots of potential unauthorized fishing and activity of foreign-owned vessels.
Using big data processing and a compilation of global datasets, researchers from Global Fishing Watch, the Marine Geospatial Ecology Lab from Duke University, and Stockholm Resilience Centre were able to track and analyze 35,000 commercial fishing and support vessels to reveal their changing identities and enable the reconstruction of vessel histories to demonstrate reflagging patterns.
