In a move hailed as a turning point for marine conservation, global governments have agreed to implement widespread international trade bans and restrictions aimed at protecting sharks and rays facing extinction. More than 70 species, including oceanic whitetip sharks, whale sharks, and manta rays, are now under new safeguards established under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). This United Nations treaty requires member countries to regulate or prohibit international trade in species whose survival is threatened. Sharks and rays gain landmark protections as nations move to implement these new regulations, marking a significant commitment to preserving these vital marine predators.

Key Developments
The sweeping conservation measures were adopted at the treaty’s 20th Conference of the Parties (COP20) in Samarkand, Uzbekistan. This signals a global commitment to curb the demand for shark meat, fins, and other products derived from these animals. According to Luke Warwick, director of shark and ray conservation at Wildlife Conservation Society (WCS), the global market for sharks and rays is worth nearly $1 billion annually. The new CITES regulations are designed to address overfishing, which is identified as the primary driver of the decline in shark and ray populations. Sharks and rays gain landmark protections as nations move to control this pervasive threat.
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 developing new technologies to combat the illegal trade of sharks, further underscoring the multi-faceted approach needed to safeguard these species. The collaboration between international agreements and technological advancements is crucial. Sharks and rays gain landmark protections as nations move to enforce these new measures, and technology plays a vital role in tracking and preventing illegal trading.
The Extent of the Threat to Sharks and Rays
More than a third of all shark and ray species are now threatened with extinction. Pelagic shark populations, which inhabit the open ocean, have declined by over 70 percent in the last 50 years. Reef sharks have almost disappeared from one in five coral reefs worldwide. This alarming trend highlights the urgent need for conservation efforts. Warwick describes this as a “silent crisis,” noting that the severity of the situation has only become apparent in the last decade. The primary cause of this decline is overfishing, exacerbated by the fact that sharks and rays have historically been treated as a fast-reproducing seafood commodity, unlike tuna and other commercially valuable fish that have been tightly regulated for decades. Sharks and rays gain landmark protections as nations move to address these critical declines.
Unlike many fish species that produce millions of eggs annually, sharks and rays mature slowly and produce significantly fewer offspring. Manta rays, for example, may only give birth to seven live pups in their lifetime. Despite this low reproductive rate, they have been caught and killed at rates similar to other fish, leading to catastrophic declines in their populations. Manta rays are primarily targeted for their gill plates, which are used in some traditional medicines in Asia, despite a lack of scientific evidence supporting their effectiveness. Shark fins are a delicacy in luxury Chinese cuisine, and shark meat is increasingly sold as a low-cost protein source, including in pet food. Sharks and rays gain landmark protections as nations move to halt these destructive practices.
Technological Advancements in Conservation
The Predator Ecology and Conservation Lab at Florida International University is at the forefront of developing technologies to combat the illegal trade of sharks. These technologies include advanced tracking systems and DNA analysis to identify shark products and their origins. Such innovations are crucial for enforcing the new CITES regulations and ensuring that illegal trade is detected and prevented. These technological advancements are essential tools. Sharks and rays gain landmark protections as nations move to integrate technology into their conservation strategies.
Gabriel Vianna, a shark researcher from the Charles Darwin Foundation, emphasizes the role of the cosmetic industry in driving the trade of deep-water shark species like gulper sharks. Their livers are harvested for squalene, a key ingredient in topical skincare products and makeup. Vianna advocates for the use of synthetic alternatives to reduce the demand for shark-derived squalene. The increasing use of squalene in pharmaceuticals and even COVID-19 vaccines further exacerbates the problem. Technological innovation in creating synthetic alternatives is vital. Sharks and rays gain landmark protections as nations move to reduce reliance on shark-derived products.
Implications of the New Protections
The new CITES regulations represent a significant shift in the global approach to marine conservation. For much of its 50-year history, CITES focused on protecting iconic land species and charismatic marine species like sea turtles. The inclusion of over 70 shark and ray species marks a recognition of the critical role these apex predators play in maintaining healthy marine ecosystems. The international ban on sea turtle trade in 1981 led to remarkable comebacks for some species, providing a model for the potential impact of these new shark and ray protections. Sharks and rays gain landmark protections as nations move to implement and enforce these crucial measures.
These new protections are a powerful step toward ensuring that these species have a real chance at recovery. By regulating and prohibiting international trade, CITES aims to reduce the demand for shark and ray products, thereby alleviating the pressure on their populations. The success of these measures will depend on the commitment of member countries to enforce the regulations and invest in conservation efforts. Sharks and rays gain landmark protections as nations move to prioritize the health and sustainability of marine ecosystems.
The recent CITES agreement marks a pivotal moment for marine conservation, offering hope for the recovery of shark and ray populations worldwide. As nations move to implement these regulations, the collaborative efforts of governments, conservation organizations, and technological innovators will be crucial in ensuring the long-term survival of these vital marine predators. Sharks and rays gain landmark protections as nations move to safeguard our oceans for future generations.
