Global Fishing Watch has launched an improved version 5 of our automatic identification system (AIS), vessel identity, imagery and vessel monitoring system (VMS) data pipelines, including a new general fishing model and a new vessel classification model.
New study provides first global dataset examining intentional disabling of automatic identification system devices across commercial fisheries The ocean is vast and ship crews rely on several tools to navigate it safely. One of these tools is the automatic identification system, commonly referred to as AIS, which uses GPS transponders to regularly broadcast critical information, […]
Fishing vessels with Automatic Identification Systems (AIS) increasing by 10 to 30 percent each year. 19 November 2019, Rome – A new global atlas – the first-ever of its kind – analyses the opportunities and challenges of using Automatic Identification Systems (AIS) to monitor fishing activity around the globe. AIS is a tracking technology designed […]
What information can be accessed in the public apparent fishing effort dataset and what has changed in the latest release?
International agreement to track vessels will bring greater accountability, build compliance and help protect fishers Despite being a global, publicly shared resource, there is little transparency about what takes place across the ocean—especially when it comes to fishing on the high seas. Vessel tracking is a key method to understanding this activity, but Global Fishing […]

Are whaling vessels that operate without using aids to avoid vessel collision putting the safety of biodiversity and people at risk? This week the International Whaling Commission (IWC) has convened in Slovenia. The gathering marks the 30th anniversary of the commission’s moratorium on commercial whaling.
Datasets and Code: Apparent Fishing Activity Global Fishing Watch’s flagship dataset is apparent fishing activity based on transmissions broadcast using automatic identification system (AIS) and vessel monitoring systems (VMS) shared by country partners. In 2018, we published the first global assessment of commercial fishing activity in the journal Science. Our research found that fishing is […]
Datasets and Code: Vessel Identity Transparency plays a central role in promoting the sustainability of marine resources and advancing ocean governance. Reliable information about vessel identity is a fundamental pillar of ocean transparency. However, such data is often fragmented, incomplete or inconsistent across multiple sources — and in many cases, it is not publicly available […]
Ask the Expert Tim Hochberg Senior machine learning engineer How do you match automatic identification system data with satellite imagery to identify publicly tracked vessels? Automatic identification systems, commonly referred to as AIS, transmit a ship’s position and alerts others to its whereabouts. While originally designed as a collision avoidance mechanism, AIS is regularly used […]
