SkyLight sources data from satellite images, shipping records and information collected by dock officials. Machine learning is then applied in order to predict which ships might be engaging in illegal fishing and where. "The stakes are high and the threat is real," Dave Stewart, the head of government affairs for Allen's company Vulcan Inc., told Bloomberg. "Very few countries have access to timely, actionable intelligence and technology to address this issue. We are developing an illegal fishing intelligence network that will bring this to them."

Illegal fishing contributes to overfishing and the continued decline of important species populations. The World Wildlife Fund says that around 520 million people around the world rely on fishing to sustain their livelihoods and 2.6 billion depend on fish as a staple in their diets. Unsustainable fishing practices are a growing problem and it's one that others have tried to tackle before Allen. Global Fishing Watch, of which Google is a part of, has been combatting illegal fishing since 2014 and UK researchers developed a similar program called Project Eyes in 2015.

Allen's funds are being used to set up the service, and fees paid by those using SkyLight will go towards expanding and sustaining the program.
