Scientists at the world’s largest gathering of shark experts have issued a stark warning: the global shark conservation outlook is increasingly grim, with many species facing a precarious future due to systemic failures in protection and enforcement. The consensus among researchers is that while policy frameworks are evolving, the rate of decline for these apex predators is currently outpacing the implementation of safeguards.
The crisis is not limited to a single region or species but is a systemic collapse occurring across diverse oceanic habitats. From the deep trenches of the high seas to the coastal waters of the Pacific, the pressure from overfishing, the illegal fin trade, and habitat degradation has pushed numerous shark and ray populations to the brink. Experts emphasize that because these animals migrate across vast distances, national protections are insufficient without a coordinated, international legal architecture.
At the center of this effort is the newly established High Seas Treaty, formally known as the Biodiversity Beyond National Jurisdiction (BBNJ) agreement. This landmark treaty seeks to create a legal mechanism for establishing marine protected areas (MPAs) in international waters—territory that covers nearly two-thirds of the ocean and has historically remained a “wild west” of unregulated exploitation. For sharks and rays, which do not recognize political boundaries, this treaty represents the most viable path toward long-term survival.
The gap between policy and population
Despite the adoption of the BBNJ agreement, scientists warn that there is a dangerous lag between the signing of treaties and the actual protection of animals in the water. The “grim outlook” cited by researchers stems from the fact that many shark species are being depleted faster than the legal frameworks required to save them can be ratified and enforced.
The primary driver remains the demand for shark fins and meat, coupled with the incidental capture of sharks as bycatch in industrial fisheries. While some nations have implemented bans on shark finning, the lack of transparency in global supply chains allows illegally caught sharks to enter markets. This is compounded by a critical lack of data. in many parts of the ocean, researchers are essentially flying blind, unable to accurately track population collapses until it is too late for recovery.
To visualize the scale of the challenge, the following table outlines the current state of high seas governance versus the targets set by the international community:
| Metric | Current Status (Approx.) | 2030 Global Target (30×30) |
|---|---|---|
| High Seas Protection | Less than 1% effectively protected | 30% of global ocean area |
| BBNJ Treaty Status | Adopted; awaiting wide ratification | Fully operational legal framework |
| Species Monitoring | Fragmented, regional data | Integrated, real-time global tracking |
The Pacific frontline and the BBNJ framework
The Pacific region has become a critical focal point for these conservation efforts. Pacific island nations, which steward vast swaths of the ocean, are being urged to align their domestic fisheries management with the new high seas framework. The goal is to create “blue corridors”—protected migratory paths that allow sharks to move safely between national waters and the high seas.
The challenge for these nations is balancing economic reliance on fisheries with the ecological necessity of protecting apex predators. Scientists argue that the collapse of shark populations would trigger a trophic cascade, leading to the overpopulation of smaller prey species and the eventual collapse of the incredibly fisheries that local economies depend on. The International Union for Conservation of Nature (IUCN) has frequently highlighted that the loss of these predators destabilizes the entire marine food web.
Key priorities for the Pacific alignment include:
- Standardizing Bycatch Protocols: Implementing mandatory reporting and mitigation techniques to reduce the accidental killing of sharks in tuna fisheries.
- Cross-Border MPAs: Establishing protected zones that overlap national boundaries to protect breeding and nursery grounds.
- Enforcement Technology: Utilizing satellite monitoring and AI-driven surveillance to combat illegal, unreported, and unregulated (IUU) fishing.
A roadmap toward Colombo 2026
While the current data is sobering, the scientific community is pivoting toward a more aggressive implementation strategy. The focus has shifted from merely identifying the problem to creating actionable, scalable solutions that can be deployed before population tipping points are reached. This momentum is building toward the next major milestone in the field.
The International Shark Conference has designated Colombo, Sri Lanka, as the host city for the 2026 summit. This event is expected to serve as a critical checkpoint for the 30×30 goal—the global ambition to protect 30% of the world’s oceans by 2030. The Colombo conference will likely be the venue where the success or failure of the BBNJ treaty’s early implementation phase is evaluated.
For the treaty to be effective, it requires a critical mass of nations to formally ratify the agreement. Once ratified, it will allow for the creation of high-seas MPAs through a vote of the parties, bypassing the often-stalled consensus-based models of previous regional fisheries management organizations. This shift in governance is seen as the only way to protect highly migratory species that traverse multiple jurisdictions.
The immediate next step for the global community is the continued ratification of the BBNJ treaty by member states. The United Nations continues to urge signatory nations to complete their domestic legal processes to bring the treaty into force. The window for action is narrow, and the coming two years will determine whether the warnings issued at the most recent conference result in a policy pivot or a permanent loss of biodiversity.
