Loitering is when a single vessel exhibits behavior indicative of a potential encounter event. Loitering is estimated using automatic identification system (AIS) data, including vessel speed, duration in a given location, and distance from shore. Loitering occurs when a vessel travels at average speed of < two knots, while at least an average of 20 […]
Events and vessel detections may show in our platform, but tracks are missing.
Tracking refrigerated cargo ships, commonly called reefers, can help address illegal fishing in the Gulf of Guinea Transshipment, or the transfer of fish from one vessel to another, is a vital part of the global commercial fishing industry. It touches a wide variety of seafood products, from bigeye and skipjack tuna all the way to […]
User Guide English | Español | Français | Portuguese |中文 Menu Introduction The Global Fishing Watch map is the first open-access online platform for visualization and analysis of vessel-based human activity at sea. Powered by satellite technology and machine learning, the map merges multiple types of vessel tracking data to provide a view of global […]
NGO collaboration will help fishery managers ensure transfer of catch is both legal and verifiable The transfer of fresh catch from fishing vessels to refrigerated cargo ships is an important but often opaque part of the industrial fishing sector. A new public global monitoring portal is a turning point in efforts to manage this activity. […]
Update integrates features from Carrier Vessel Portal directly into the Global Fishing Watch map.
New APIs provide statistics about fishing effort and vessel events worldwide or for a custom region.
Datasets and Code: Transhipment Thanks to a practice known as transshipment—the transfer of catch between vessels—fishers can stay at sea for months at a time without ever having to take a costly and time-consuming trip back to port to offload catch. However, transshipment also obscures the seafood supply chain from hook to port and hobbles […]

Global Fishing Watch has launched an improved version (v3.0) of our automatic identification system (AIS) data pipeline. The AIS data pipeline is the series of processes that we use to convert the raw satellite AIS ingested data to the data products, such as machine learning estimates of fishing activity, identity data that combines merged external […]
