Global Shark Conservation

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.

  • Hong Kong Boosts Penalties for Illegal Trade in Sharks and Rays

    In the marine conservation community, Hong Kong has long been known as a bad actor—the center of the global trade in shark fins and a bustling market for a huge range of illegal wildlife products. Hong Kong’s Legislative Council took a step in January toward shedding that image by adopting stiffer penalties for illicit trade in endangered sharks and rays. Read More

  • Samoa Adds to Pacific Conservation Legacy by Creating Shark Sanctuary

    The waters surrounding the South Pacific island nation of Samoa are prime habitat for nearly 30 species of sharks and rays, and today the government took a critical step toward protecting them. At a forum to celebrate the region’s history of strong shark conservation, Prime Minister Tuilaepa Aiono Sailele Malielegaoi announced that the country is designating all of its national waters a...
