Global analysis shows where fishing vessels’ identification devices have been switched off

New research displays intentional disabling of automatic identification system devices to provide insights into illegal, unreported and unregulated fishing activity A new analysis harnesses automatic identification system, or AIS, data to provide information about global fishing activity, including illegal, unreported and unregulated fishing. Originally designed as a collision avoidance tool, AIS can be intentionally disabled—sometimes […]

Transshipment Monitoring Portal Brings Transparency to Fishing Industry

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.  […]

IUU Fishing Risk Insights Dataset Release

Eleven new behavior risk insights are now available in the data download portal. This new dataset helps practitioners and researchers identify and track vessels with a higher probability of engaging in illegal, unreported, and unregulated fishing.

A Radar-Illuminated Ocean Reveals Dark Fleets

Satellite radar imagery is lighting up our view of previously unseen fishing patterns around the world Last week, we announced the winners of the xView3 contest to use satellite radar imagery and artificial intelligence to reveal vessels at sea. This week, we give you a gist of what this technology can do when deployed at […]

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. Global Fishing Watch (GFW) and Trygg Mat Tracking (TMT) have been working with partners in the Northwest Indian Ocean region, including the Somali government, to identify large-scale illegal fishing that is occurring inside the waters of […]

Datasets and Code: Vessel Classifications

Datasets and Code: Vessel Classification How we classify vessels Global Fishing Watch uses a database of vessel records containing registry and automatic identification system (AIS)-based information to identify vessels with a known class. A two-part system — combining a convolutional neural network and a random forest model — is then trained to identify other vessels […]

Characterizing Gaps in the Data

Just a few years ago the very idea of collecting billions of radio signals from ocean-going vessels all around the world and creating a global map of their activity in near-real time would have been unthinkable. But today’s cloud computing technology allows us to do amazing things with huge amounts of data.

Identification of ‘dark vessels’

Using bright lights to reveal the ‘dark’ fleet Christopher Elvidge with the U.S. National Oceanic and Atmospheric Administration (NOAA)’s Earth Observation Group writes about matching night-time imagery with monitoring data from fishing vessels to shed new light on the ‘dark’ fleet. The challenges with tracking vessels Vessel tracks from Automatic Identification System (AIS) and Vessel […]
