Illegal Fishing Hotspot Identified in Northwest Indian Ocean

Nearly 200 Iranian vessels detected in Somali and Yemeni waters represent one of the world’s largest illegal fishing operations. By Charles Kilgour, director of fisheries analysis, Global Fishing Watch and Duncan Copeland, executive director, Trygg Mat Tracking  Global Fishing Watch (GFW) and Trygg Mat Tracking (TMT) have been working with partners in the Northwest [...]

Illuminating global fishing activity with satellite AIS

This article was produced and first published by our data partner, Spire Global. Transparency in a whole new light In February this year, a Vietnamese ship entered Indonesian waters, likely fished illegally, and then returned to port without consequence. By March, it was back at sea. There were no signs to indicate that the [...]

Towards a radar-illuminated ocean

At Global Fishing Watch, we use cutting-edge technology to visualize, track and share data about global fishing activity in near real-time and for free. Our primary dataset comes from data about a vessel’s identity, type, location, speed, direction and more that is broadcast using the Automatic Identification System (AIS) and collected via satellites and [...]

Shedding a light on intruders at sea

Dyhia is a Principal Investigator of Fisheries at Ecotrust Canada. The social, economic, and human toll of illegal fishing Illegal fishing drains fish resources from the waters of both poor and rich countries. Over $23 billion US are lost every year to illegal fishing. It is estimated that one in every four [...]

The Global Atlas of AIS-based Fishing Activity

In 2018, Global Fishing Watch (GFW) published the first ever global maps of fishing activity using AIS data. These fishing maps drew on billions of GPS positions broadcast by over 60,000 fishing vessels, and they revealed fishing operations in all oceans in incredible detail. Click on the image to access the atlas. [...]

Predicting overlap of tunas, sharks, and ships at sea

Tim White is a PhD candidate at Stanford University’s Hopkins Marine Station. His recent publication in Science Advances, Predicted hotspots of overlap between highly migratory fishes and industrial fishing fleets in the Northeast Pacific, focuses on how vessel tracking and fish habitat models can help inform management of sharks and tunas. How do you [...]

The Tale of the Albatross and the Algorithm

The first-ever satellite mapping of fishing vessel behaviours has identified that very few vessels are using one of the key techniques to avoid accidentally killing albatrosses. Researchers hope a new analytics tool demonstrates that satellite data can help monitor efforts to reduce seabird mortality in fishing operations, and drive more transparency in general in the global fishing [...]
