As shark and ray populations cross vast ocean boundaries, a recently enforced treaty provides a promising new route for their protection, offering international cooperation where national efforts alone fall short.
- The treaty came into force in January 2026, gaining global attention.
- Migratory sharks and rays often traverse boundaries where protection is inconsistent.
- Sri Lanka and other nations emphasize international cooperation for effective enforcement.
What happened
In January 2026, the Biodiversity Beyond National Jurisdiction (BBNJ) Agreement, also called the High Seas Treaty, officially took effect. This landmark international accord aims to enhance the protection of marine biodiversity in the vast open oceans beyond any country’s exclusive economic zones, where governance and conservation have historically been fragmented. At a recent meeting in Sri Lanka, shark scientists and conservation advocates celebrated the treaty’s potential to reshape efforts to conserve highly migratory species such as sharks and rays.
These marine animals often migrate across multiple countries’ waters and enter the high seas, where traditional protections wane. The treaty specifically creates a framework for international cooperation and coordinated conservation initiatives, including the establishment of marine protected areas and mandatory environmental impact assessments to regulate potentially harmful activities. Countries like Sri Lanka, situated along key migratory corridors, have ratified the treaty, signaling a collective commitment to safeguarding these ocean travelers.
Why it feels good
The BBNJ Agreement addresses a critical gap in ocean conservation—protecting species that do not recognize political borders. Sharks and rays can roam thousands of miles, and when they leave protected national zones, they often become vulnerable to industrial fishing, bycatch, habitat degradation, and the effects of climate change. The treaty acknowledges the interconnected and dynamic nature of marine ecosystems, encouraging protection measures that span the entirety of a species’ range rather than isolated pockets.
Conservationists find hope in this coordinated approach because it boosts protections where individual country efforts alone are insufficient. The treaty also mandates environmental impact assessments for activities in the high seas, reflecting a precautionary principle that prioritizes the ocean’s health. This proactive stance enables stakeholders to act confidently despite incomplete data, accelerating the establishment of marine protected areas and other conservation tools to safeguard these migratory species.
What to enjoy or watch next
Looking ahead, the real test for the High Seas Treaty will be its implementation and cooperation among nations, international organizations, and stakeholders. Experts highlight the importance of connecting this treaty with existing agreements like the Convention on Migratory Species, the Convention on Biological Diversity, and CITES to ensure harmonized and effective management across different governance frameworks. Expect ongoing discussions and collaborations focused on creating practical protections tailored to migratory routes and ecological needs.
For regions like the Indian Ocean, where overexploited fisheries and harmful fishing practices threaten marine life, the treaty’s impact could become a blueprint for improved ocean governance globally. Following how countries translate the treaty’s goals into concrete conservation actions will be encouraging for those committed to reversing biodiversity loss and fostering healthier, more resilient oceans.
