MARINE RESERVES & SHARK SANCTUARIES
Illegal fishing in a shark sanctuary
In collaboration with Google’s Global Fishing Watch (GFW), we are working to identify illegal shark fishing in regions with protected shark populations. Over half of 15 satellite tags that were affixed to grey reef sharks in the Republic of the Marshall Islands’ (RMI) Shark Sanctuary in late 2015 ended up on fishing vessels operating in the western Pacific Ocean. By comparing Argos satellite tracks from our RMI ‘shark tags’ to AIS tracks from vessels transmitting in the same geographic region, we are working to identify the vessel type and activity corresponding to the illegal harvest of these ‘protected’ sharks.
