Unmasking the shadows: Company uses science to exposing 'Dark' vessels at sea

Global Fishing Watch, an organization dedicated to ocean transparency and sustainability, has developed an innovative map layer that exposes hidden vessels worldwide.

These "dark fleets" are vessels that intentionally hide their location and remain undetected in public monitoring systems. By leveraging satellite radar imagery and machine learning, this groundbreaking map provides a comprehensive global view of potentially illegal fishing activity, offering valuable insights into the true scale of human impact on the ocean.

Using data from automatic identification systems (AIS) and vessel monitoring systems, Global Fishing Watch combines satellite imagery and its proprietary fishing detection algorithm to precisely track fishing efforts. The interactive map showcases detailed vessel tracks and events, encompassing fishing activities, port visits, encounters with other vessels, and littering.

In addition to vessel tracking, Global Fishing Watch has developed a new layer that uncovers hidden or “pirate” vessels that intentionally disable their signals or evade public monitoring systems. This vital information aids authorities in identifying suspicious activities, such as illegal fishing or previously unquantified fishing pressures.

Global Fishing Watch's groundbreaking work holds significant implications for ecological systems, biodiversity, and the delicate balance of the food chain. By enhancing our understanding of human activity at sea, it enables the development of targeted conservation measures to safeguard vulnerable habitats and species — this is particularly important as 17% of the global animal product comes from out oceans.

The organization promotes transparency and responsible fishing practices, preserving biodiversity by reducing overfishing and mitigating unintended bycatch. This ensures a healthy and sustainable food chain, supporting marine ecosystems and the diverse array of life that depends on the ocean.
