Working with government leaders, scientists, fisheries experts, diplomats, and even survivors of shark attacks, Pew works to highlight the plight of sharks from overfishing and to urge countries to take action to conserve them.
Sharks have roamed our oceans since before the time of dinosaurs, but their long reign at the top of the ocean food chain may be ending. The onset of industrial fishing over the past 60 years has drastically depleted their populations. Of the shark and ray species assessed by scientists for the International Union for Conservation of Nature (IUCN), nearly 50 percent are threatened or near-threatened with extinction.
Each year, between 63 million to 273 million sharks are killed in the world’s commercial fisheries. The catch of shark for their fins, meat, liver oil, cartilage, and other parts remains largely unregulated in most of the world, driving some populations toward extinction.
In general, sharks grow slowly, mature late and produce few young over long lifetimes, leaving them exceptionally vulnerable to overexploitation and slow to recover from depletion. As key predators, their depletion also has risks for the health of entire ocean ecosystems. For example, tiger sharks have been linked to the quality of seagrass beds through their prey, dugongs and green sea turtles, which forage in these beds. Without tiger sharks to control their prey’s foraging, an important habitat is lost.
Pew has identified the present moment as a critical time to reverse the global decline of shark populations. We work internationally to influence the fishing nations and treaty organizations that regulate high seas fisheries. In addition, we work with nations whose waters still have diverse populations of sharks to declare shark sanctuaries and to advocate for international shark conservation.

There are more than 200 species of sharks and rays found in the waters of the Philippines. These species play a critical role in maintaining the country’s marine ecosystem and are a huge draw for tourists. Yet many are still fished and overexploited, and only a few have received the protections they need to recover. Read More
Further solidifying West Africa’s emerging leadership on shark conservation, representatives of 12 countries in the region gathered in Dakar, Senegal, in early December for a workshop on how best to implement recently adopted international trade regulations to protect several species of sharks and rays.
