The shrimp in your salad or tuna on your plate may have been caught illegally in areas threatened by overfishing. But tracing suspect seafood is a tricky task, given that many boats operate in unseen swaths of the ocean.
Global Fishing Watch, a new project from Oceana, SkyTruth and Google, aims to crack down on illegal fishing by training the watchful eye of surveillance satellites on the world's approximately 35,000 commercial fishing vessels.
The online technology platform collects more than 22 million data points per day from hundreds of thousands of ships. The free tool, still in its beta phase, lets anybody monitor and track activities of large commercial fishing vessels in near real time.
