Introducing Global Fishing Watch

Global Fishing Watch (GFW), a free online tool from Oceana, SkyTruth, and Google, reveals the apparent fishing activity of over 35,000 commercial vessels globally. Regularly updated with data since 2012, GFW publicly shares vital information to enhance ocean health, support fishery management, and combat illegal fishing. This revolutionary tool empowers governments, journalists, and citizens to track vessels, enforce rules, and protect marine ecosystems.

GFW uses public Automatic Identification System (AIS) data, collected by satellite and terrestrial receivers. Over 20 million data points are added daily, enabling GFW to track vessel movement and classify it as "fishing" or "non-fishing" activity.
