eShark — The Global Shark & Ray Collaboration project
Since 2003, eShark has delivered measurable global impact — contributing to the protection of 100+ shark and ray species across more than 19 million km² of ocean. That protection safeguards the natural capital underpinning fisheries, tourism, coastal livelihoods, and blue economy investments worldwide.
Now, with the eOceans app, this collaboration operates continuously — generating real-time data across species, sectors, and geographies. Better data reduces risk, strengthens management, and protects the economic value oceans provide.

A monumental collaboration.

Why use the eOceans app and not just a shark app?
Sharks and rays don’t exist in isolation — they are part of a highly complex, dynamic and fast changing ocean. Standalone apps miss the bigger picture. eShark on eOceans links every sighting to other species, threats, and human activity, creating a real-time, global view of sharks and rays, their threats, and the ocean.
Become a field observer
If you know your sharks and rays, share your field observations:
🌀 Download the eOceans app (iOS, Android)
🌀 Explore and survey your sites, anywhere
🌀 Log your shark & ray observations — including zeros!
🌀 Log threats — lost fishing gear, pollution, etc.
As you add observations, they are checked by scientists and then transformed into results in real-time.
Become an influencer or sponsor:
Influencers and sponsors help scale the collaboration by spreading the word.
eShark is led by experts in citizen science shark and ray science
Examples of our research:
🌀 100 million sharks killed each year — threatening populations, livelihoods
🌀 Global manta rays and manta-driven tourism is threatened by IUU fishing
🌀 The Great Fiji Shark Count, eShark Thailand, eManta, and more.
🌀 Sharks disappear on reefs close to human populations, unless strong tourism and conservation
🌀 Shark Sanctuaries have many benefits for sharks and rays, but don’t address all threats
🌀 Yellow stingrays are declining throughout their range, unnoticed by science
🌀 Many more (see impact page for details)
eShark data and results don’t just sit in databases or in peer-reviewed publications— they inform communities, global policy, and conservation decisions.
🌀 Sharks and rays gain protection from illegal, unreported, unregulated fisheries
🌀 International trade regulations strengthened
🌀 Shark Sanctuaries implemented and improved
🌀 Pollution reduction strategies implemented
