In a landmark move for marine conservation, global governments have agreed to implement widespread international trade bans and restrictions on numerous shark and ray species facing the threat of extinction. The agreement, reached last week, brings new safeguards to over 70 species, including oceanic whitetip sharks, whale sharks, and manta rays, 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 completely prohibit international trade in species whose survival is at risk. Sharks and rays gain landmark protections as nations move to acknowledge the critical role these apex predators play in maintaining healthy marine ecosystems. The new regulations mark a significant step towards reversing the decline of these vulnerable species.

Key Developments
The sweeping conservation measures were adopted at the treaty’s 20th Conference of the Parties (COP20) in Samarkand, Uzbekistan. This signals a significant global commitment to curb the demand for shark meat, fins, and other products derived from these animals. Luke Warwick, director of shark and ray conservation at Wildlife Conservation Society (WCS), notes that sharks and rays have been caught and traded for decades, contributing to a global market valued at nearly $1 billion annually. Sharks and rays gain landmark protections as nations move to address this unsustainable practice.
Diego Cardeñosa, an assistant professor at Florida International University and lead scientist at the school’s Predator Ecology and Conservation Lab, emphasized the importance of these protections. His lab is actively developing new technologies to combat the illegal trade of sharks. According to Cardeñosa, “These new protections are a powerful step toward ensuring these species have a real chance at recovery.” The implementation of these CITES regulations is expected to significantly impact international trade practices related to these vulnerable marine animals. Sharks and rays gain landmark protections as nations move to enforce these new measures.
Understanding the Declining Populations
More than a third of all shark and ray species are now classified as threatened with extinction. Pelagic shark populations, those inhabiting the open ocean, have experienced a staggering decline of over 70 percent in the last 50 years. Reef sharks have virtually disappeared from one in five coral reefs globally. Warwick describes this as a “silent crisis,” noting that the severity of the situation has only become apparent in the last decade. Overfishing is identified as the primary driver of these population declines. Sharks and rays gain landmark protections as nations move to combat overfishing and its devastating effects.
Unlike commercially valuable fish such as tuna, which have been subject to stringent regulations for decades, sharks have historically lacked similar controls on their trade. They have often been treated as a readily available seafood commodity. Warwick points out that sharks and rays have been managed as if they were similar to other fish species, despite their significantly different reproductive rates. While many fish produce millions of eggs annually, sharks and rays mature slowly and produce far fewer offspring. Manta rays, for example, may only give birth to a maximum of seven live pups in their entire lifetime. The unsustainable practice of catching and killing them at the same rate as other fish has led to catastrophic population declines. Sharks and rays gain landmark protections as nations move to correct these past oversights.
The Driving Forces Behind Shark and Ray Trade
Manta rays are primarily targeted for their large gill plates, which are used in some traditional medicines in Asia, believed to detoxify the body and boost immunity, despite the lack of scientific evidence supporting these claims. Their meat is sometimes used as animal feed or consumed locally. Shark fins remain a prized delicacy in luxury Chinese cuisine, particularly in expensive dishes like shark fin soup. Shark meat is also increasingly sold as a low-cost source of protein and is a common ingredient in cat and dog food. Sharks and rays gain landmark protections as nations move to address these diverse demands contributing to their decline.
The livers of deep-water shark species, such as gulper sharks, are harvested for their oil, which is used to produce squalene. Squalene is a key ingredient in topical skincare products and makeup. Years of unregulated trade in these species have resulted in population declines exceeding 80 percent in some regions. Gabriel Vianna, a shark researcher from the Charles Darwin Foundation, highlights the cosmetic industry’s role in driving the trade of these sharks. Squalene has also seen increased use in pharmaceuticals and even COVID-19 vaccines in recent years. Vianna advocates for the use of synthetic alternatives to avoid exploiting these vulnerable species. Sharks and rays gain landmark protections as nations move to regulate the trade driven by these industries.
Impact on Global Markets and Conservation Efforts
The recent CITES decisions mark a significant turning point in marine conservation. For much of its 50-year history, the convention has primarily focused on protecting iconic land species, such as elephants, rhinos, primates, and parrots, as well as charismatic marine species like sea turtles. Warwick notes that the international ban on all international trade of sea turtles, imposed by CITES in 1981, played a crucial role in the remarkable comeback of some sea turtle species in recent decades. Only in the last 10 years has the convention gradually begun to recognize the urgent need to protect sharks and rays. Sharks and rays gain landmark protections as nations move to broaden the scope of conservation efforts.
These new regulations have the potential to reshape global markets related to shark and ray products. The stricter trade controls are expected to reduce demand and disrupt existing supply chains, potentially leading to price increases for alternative products and driving innovation in sustainable substitutes. The long-term success of these protections will depend on effective enforcement by participating countries and continued efforts to raise awareness among consumers about the importance of marine conservation. Sharks and rays gain landmark protections as nations move to enforce and monitor these regulations.
The agreement reached at CITES COP20 represents a critical step forward in safeguarding the future of sharks and rays. By implementing international trade bans and restrictions, governments are acknowledging the vital role these species play in marine ecosystems and taking action to address the threats they face. While challenges remain in enforcing these regulations and combating illegal trade, the commitment demonstrated by these nations offers a glimmer of hope for the recovery of these vulnerable populations. Sharks and rays gain landmark protections as nations move to secure a healthier future for our oceans.
