In a move hailed as a turning point for marine conservation, global governments have recently agreed to sweeping international trade restrictions aimed at protecting sharks and rays. More than 70 species, including oceanic whitetip sharks, whale sharks, and manta rays, now have increased safeguards under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). This United Nations treaty mandates that participating countries regulate or prohibit international trade in species threatened with extinction. The recent decisions made at the treaty’s 20th Conference of the Parties (COP20) signal a significant global commitment to address the demand for shark meat, fins, and other products. Sharks and rays gain landmark protections as nations move to implement these critical measures.

Key Developments
The conservation measures were adopted at COP20 in Samarkand, Uzbekistan, and represent a landmark agreement to curb the trade of shark and ray products. The new protections directly address the unsustainable demand for shark meat, fins, and other derivatives that have driven many species to the brink of extinction. According to Luke Warwick, director of shark and ray conservation at the Wildlife Conservation Society (WCS), the global market for these products is worth nearly $1 billion annually. These new regulations aim to drastically reduce this demand. Sharks and rays gain landmark protections as nations move to enforce these new trade bans and restrictions.
Diego Cardeñosa, an assistant professor at Florida International University, emphasized the importance of these protections for the recovery of shark and ray populations. His lab is actively developing new technologies to combat the illegal trade of sharks, further contributing to conservation efforts. The agreement represents a powerful step toward ensuring these species have a real chance at recovery, especially considering that over a third of shark and ray species are now threatened with extinction.
The Tech Angle: Combating Illegal Trade
The fight to protect sharks and rays isn’t just about policy; technology plays a crucial role. Researchers are developing innovative methods to track and trace shark products, helping to identify and disrupt illegal trade routes. DNA barcoding, for instance, allows scientists to identify the species of origin for shark fins and meat, even when these products are processed or dried. This technology is essential for enforcing CITES regulations and holding poachers accountable. Sharks and rays gain landmark protections as nations move to utilize these technological advancements.
Furthermore, satellite tagging and acoustic monitoring are being used to track the movements of sharks and rays in the wild. This data helps scientists understand their migration patterns, identify critical habitats, and assess the impact of fishing activities. This information is vital for developing effective conservation strategies and establishing marine protected areas. As technology advances, it provides increasingly sophisticated tools for monitoring and protecting these vulnerable species.
Drivers of Decline and Conservation Challenges
Overfishing is the primary driver behind the decline of shark and ray populations. Unlike tuna and other commercially valuable fish, sharks have historically lacked strict regulations on their trade, leading to unsustainable exploitation. Sharks and rays reproduce much slower than many other fish species, making them particularly vulnerable to overfishing. Manta rays, for example, may only give birth to seven live pups in their lifetime. The lack of regulation, coupled with their slow reproductive rates, has resulted in catastrophic population declines. Sharks and rays gain landmark protections as nations move to address these long-standing challenges.
The demand for shark fins, meat, and liver oil fuels the overfishing crisis. Shark fin soup remains a delicacy in some cultures, while shark meat is increasingly sold as a low-cost protein source. The livers of deep-water sharks are harvested for squalene, an ingredient used in cosmetics, pharmaceuticals, and even some COVID-19 vaccines. Gabriel Vianna, a shark researcher from the Charles Darwin Foundation, argues that synthetic alternatives to squalene should be used to reduce the pressure on shark populations. Sharks and rays gain landmark protections as nations move to limit the demand for these products.
Future Implications and the Role of CITES
The recent decisions made at CITES represent a significant step forward in marine conservation. For much of its 50-year history, the convention focused on protecting land species and charismatic marine animals like sea turtles. The inclusion of sharks and rays reflects a growing recognition of their importance in marine ecosystems and the urgent need for their protection. The success of CITES in protecting sea turtles, with some species making remarkable comebacks after the implementation of trade bans, offers hope for the future of sharks and rays. Sharks and rays gain landmark protections as nations move to replicate the success seen with sea turtle conservation.
These new protections mark a turning point in marine conservation, offering a real chance for shark and ray populations to recover. However, the effectiveness of these measures will depend on the commitment of individual countries to enforce the regulations and combat illegal trade. Continued research, technological innovation, and international cooperation are essential for ensuring the long-term survival of these vital marine species. Sharks and rays gain landmark protections as nations move to strengthen their enforcement efforts and promote sustainable fishing practices.
