About Tahi Opu

Tahi Opuworks with all stakeholders - fishers, coastal leaders, national governments and NGO to support all their efforts to protect the ocean and build up the Blue Economy.

Tahi Opu prides itself on using deep research to apply a holistic approach to complex fisheries and protection issues, employing investigative research techniques, traditional and cutting edge technology to understand and combat the real problems affecting the recovery of ecosystems.

Born in Timor-Leste, we are taking the 'Tahi Opu' spirit - 'the guardians of the sea' - out to the world.

Tahi Opu uses a range of technologies to fill the gap between satellite surveillance and prohibitively expensive local patrol vessels, and make credible, legally robust and cost-effective evidence gathering and enforcement possible.

The name Tahi Opu comes from Osaias' village in Atauro and means 'owner of the sea' - Osaias suggested it's use because an owner of the sea, protects the sea.
