Albatrosses Outfitted With GPS Trackers Detect Illegal Fishing Vessels

schwit1 shares a report from the Smithsonian: Capable of following fishing boats into remote regions out of reach of monitoring machines like ships, aircraft and even certain satellites, these feathered crimefighters could offer a convenient and cost-effective way to keep tabs on foul play at sea -- and may even help gather crucial conservation data along the way. [...] On top of their stamina and moxie, albatrosses also have a certain fondness for fish-toting vessels, says study author Samantha Patrick, a marine biologist at the University of Liverpool. To the birds, the fishing gear attached to these boats is basically a smorgasbord of snacks -- and albatrosses can spot the ships from almost 20 miles away. To test the birds' patrolling potential, the researchers stomped into the marshy nesting grounds of wandering albatrosses (Diomedea exulans) and Amsterdam albatrosses (Diomedea amsterdamensis) roosting on Crozet, Kerguelen and Amsterdam, three remote island locales in the southern Indian Ocean. After selecting 169 individuals of different ages, the team taped or glued transceivers, each weighing just two ounces, to the birds' backs and bid them adieu. Over the course of six months, the team's army of albatrosses surveyed over 20 million square miles of sea. Whenever the birds came within three or so miles of a boat, their trackers logged its coordinates, then beamed them via satellite to an online database that officials could access and cross-check with automatic identification system (AIS) data. Of the 353 fishing vessels detected, a whopping 28 percent had their AIS switched off. The number of covert ships was especially high in international waters, where about 37 percent of vessels operated AIS-free. [...] Because the birds and their transceivers detected only radar, no identifying information was logged. The task of verifying a boat's legal status still falls to officials, who must then decide whether to take action, Patrick explains. But in mapping potential hotspots of illegal fishing, the birds set off a chain reaction that could help bring perpetrators to justice. The results of the tracking method were published in the journal PNAS.Read more of this story at Slashdot.
