World Wildlife Fund and its partner NAVAMA has outfitted 13 Philippine tuna fishing boats with satellite trackers, the same kind used for commercial cargo. The trackers help keep the fishermen safe and at the same time show that they are fishing at designated places. An example its Princess Camile, with a little device attached to its mast that does the tracking. These boats hunt in the Mindoro Strait.
