More than 800 researchers and conservationists convened in Sri Lanka’s capital to share insights into the rapidly shrinking populations of sharks and rays, emphasizing rising fishing pressures, underreported trade, and urgent conservation needs.
- Shark and ray numbers halved since 1970 due to overfishing
- Ray meat trade surpasses fins in economic value at $2.6 billion
- Over 800 experts gather in Colombo to discuss global shark conservation
What happened
From May 4-8, over 800 scientists and conservationists from around the world met in Colombo for Sharks International, the largest conference focused on shark research and conservation. The event provided a platform to present new data and discuss threats facing sharks and rays, known collectively as elasmobranchs. Key topics included the global trade in shark meat and fins, population declines, and conservation strategies such as marine protected areas and improved enforcement.
Recent findings highlighted at the conference showed that shark and ray populations have halved since 1970, with more than a third of species now threatened with extinction. Researchers from Dalhousie University shared pioneering big-data research revealing substantial underreporting in shark and ray landings and trade flows. Their work identified major countries involved in trading these species and underscored the surprising scale of the ray meat market, which exceeds fin trade value.
Why it feels good
Despite the concerning statistics, the gathering reflects the global community’s growing awareness and dedication to protecting these ancient marine animals. The collaborative discussions and ongoing research reveal a stronger commitment to enhancing conservation efforts worldwide. Countries and organizations are increasingly focused on comprehensive strategies, including better trade monitoring, habitat protection, and rewilding initiatives that aim to restore populations.
Additionally, the spotlight on rays—a group often overlooked despite being more threatened than many shark species—is a positive step toward more inclusive conservation policies. Highlighting cultural, economic, and ecological factors driving consumption helps tailor solutions to local needs, inspiring hope that smarter regulations and community engagement can help reverse current declines.
What to enjoy or watch next
The upcoming publication by the Dalhousie University team, featuring species-level estimates of landings and trade flows, will offer critical insights to policymakers and conservationists. Their work aims to help governments implement better monitoring and reporting systems to protect vulnerable species more effectively. Monitoring initiatives and enforcement improvements discussed at the conference will also be crucial to watch for progress in protecting these marine populations.
Beyond research, efforts by countries highly involved in shark and ray trade—such as the U.S., South Korea, India, Indonesia, and Mexico—will be important to observe as they adapt regulations and conservation plans. Public engagement through awareness campaigns and sustainable seafood initiatives can also play a vital role in reducing pressure on sharks and rays, supporting healthier ocean ecosystems for the future.
