Little-to-no industrial fishing occurs in fully and highly protected marine areas
Marine protected areas (MPAs) are a fundamental tool for ocean conservation and are expanding worldwide to meet the Global Biodiversity Framework's target of protecting at least 30% of the ocean by 2030 (30 × 30) (1, 2). MPAs are established with various levels of protection; although some strictly

Global patterns and drivers of untracked industrial fishing in coastal marine protected areas
Marine protected areas (MPAs) are an essential tool to counteract the pervasive degradation of marine ecosystems and sustain their contributions to humankind (1-3). In 2022, guided by scientific recommendations, 196 countries endorsed the objective to effectively protect 30% of the ocean by 2030

Illegal fishing in marine protected areas -- satellites and AI show most bans are respected
Marine protected areas cover more than 8% of the world's oceans today, but they can get a bad rap as being protected on paper only. While the name invokes safe havens for fish, whales and other sea life, these areas can be hard to monitor. High-profile violations, such as recent fishing fleet

New research using satellite technology and AI shows that marine protected areas with strict fishing bans are largely successful in preventing illegal industrial fishing, contrary to widespread concerns about ineffective enforcement.
Satellite Technology and AI Unveil Effectiveness of Marine Protected Areas
A groundbreaking global study utilizing advanced satellite technology and artificial intelligence (AI) has revealed that marine protected areas (MPAs) with strict industrial fishing bans are largely successful in preventing illegal fishing activities

Innovative Monitoring Techniques
The study employed a combination of Automatic Identification System (AIS) data and synthetic aperture radar (SAR) imagery from the Sentinel-1 satellite constellation
1
. This innovative approach overcomes limitations of previous assessments by detecting vessels even when they attempt to evade traditional tracking methods. AI algorithms analyze these data to identify fishing activities, providing a more comprehensive view of industrial fishing patterns3
.Key Findings
The research, published in the journal Science, examined nearly 1,400 MPAs spanning about 3 million square miles (7.million square kilometers) where industrial fishing is explicitly prohibited
4
. The results were striking:- 78.5% of the studied MPAs showed no commercial fishing activity at all
4
. - On average, only about five fishing vessels per 100,000 square kilometers were detected in protected areas, compared to 42 in unprotected coastal areas
5
. - 96% of the MPAs experienced less than one day per year of alleged illegal fishing effort

Challenges and Future Directions
Despite the overall positive results, the study identified some MPAs still experiencing heavy illegal fishing, including the Chagos Marine Reserve and the Great Barrier Reef Marine Park

. This highlights the need for continued monitoring and enforcement efforts.The research also underscores the power of combining multiple datasets to overcome individual limitations. Juan Mayorga, a co-author of the study, noted that fusing AIS tracking with satellite radar imagery and AI provides a much clearer picture of human activity across the ocean
