October 2, 2018 — Japan and Peru, two of the world’s biggest players when it comes to seafood, are hoping to crack down on illegal, unreported, and unregulated (IUU) fishing in their exclusive economic zones through increased use of cutting-edge technology.
A key player in both countries’ efforts is the Global Fishing Watch, an international nonprofit organization with the goal of “advancing sustainability of the oceans through increased transparency.” Its mapping platform, which can be found on the GFW website, allows anyone to view or download data and investigate global fishing activity in near real-time, for free. GFW was founded in 2015 through a collaboration between Oceana, SkyTruth, and Google.
Global Fishing Watch’s tracking of automatic identification system (AIS) messages from ocean-going boats is now being used to fight illegal transshipment inside and near Japan’s exclusive economic zone. GFW recently signed onto a collaboration with the Japan Fisheries Research and Education Agency (FRA) and the Australian National Centre for Ocean Resources and Security (ANCORS) at the University of Wollongong to investigate IUU fishing and strengthen transparency and governance of fisheries within the region.
To detect pairs of vessels meeting at sea, GFW and analysts at SkyTruth and Google applied machine learning algorithms to more than 30 billion automatic identification system (AIS) messages from ocean-going boats to find tell-tale transshipment behavior, such as two vessels alongside each other long enough to transfer catch, crew, or supplies. AIS is a collision avoidance system that constantly transmits a vessel’s location at sea. These transmissions are collected by satellite receivers and delivered to GFW for automated processing. Nearly all refrigerated cargo vessels carry AIS and those ships receiving fish can be identified and their activity plotted on the map.
