Global fishing vessel maps
Over the past year GSMP has been analysing Automatic Identification System (AIS) data of the movements of individual fishing vessels (see global map for 2014). Satellite AIS was developed as a vessel safety and ship-to-ship anti-collision system with global coverage rather than to track fishing vessels for management purposes. But the global coverage of tens of thousands of vessels means fishing effort globally at relatively fine scale can be mapped. Data were purchased from a satellite provider and will enable us to identify where shark hotspots in the ocean are most overlapped by fishing vessel hotspots.
