Global Fishing Watch is the result of a collaboration among Google, Oceana and SkyTruth to map and measure fishing activity worldwide by mapping data from the Automatic Identification System (AIS) used by more than 100,000 vessels worldwide.
Global Fishing Watch analyzes data from the Automatic Identification System (AIS), which is collected by satellites and terrestrial receivers, to identify apparent fishing behavior based on the movement of vessels over time. A map of this data is available to anyone with an Internet connection and allows users to monitor when and where commercial fishing is occurring around the world.
This information from Global Fishing Watch can be used by governments to ensure that fishing regulations are adequately monitored and tracked allowing them to respond to illegal fishing rapidly and efficiently. The governments of Kiribati and Indonesia have been able to improve adherence to marine conservation policies by accessing data provided by Global Fishing Watch.
