Overview
In July 2026, a patrol boat operating off the coast of Gabon intercepted three industrial trawlers inside the Grand Sud Reserve. An inspection confirmed that none of the three vessels possessed a valid fishing license.
Research Context
The Grand Sud Reserve is designated as one of the largest marine protected reserves in West and Central Africa. Within its boundaries, industrial trawling is prohibited by law, set against a broader regional backdrop where illegal fishing continues in African waters.
Approach
The enforcement operation relied on remote monitoring rather than unguided offshore sweeps. Analysts at the nonprofit organization Global Fishing Watch processed and interpreted satellite data to determine where maritime patrols should focus their surveillance.
Findings
Analysis of the satellite data accurately pinpointed the locations of the unauthorized activity, allowing the patrol boat to locate and intercept all three unlicensed trawlers actively operating within the restricted marine reserve.
