COLOMBO — More than 800 researchers and conservationists gathered in Colombo, Sri Lanka’s capital, from May 4-8 for Sharks International, the world’s largest shark conference.

Presenters shared research and insights on the global trade in sharks, the plight of rays, and a range of conservation measures, including rewilding initiatives, improving marine protected area effectiveness, and the bolstering of monitoring and enforcement systems to protect threatened species.

Overfishing has halved shark and ray populations since 1970. Today, more than a third of species are threatened with extinction.
