Species Recovery: Indo-Pacific Leopard Sharks

A white wave shape.

Population Status

Indo-Pacific leopard sharks (Stegostoma tigrinum) are also called zebra sharks, hiu belimbing and other names. Once abundant in the Coral Triangle, these sharks are now nearly extinct due to overfishing and habitat loss. Like all sharks, they help maintain a healthy food web and are essential to the well-being of their entire ecosystem. 

Indo-Pacific leopard sharks haven’t responded to measures that have restored other endangered species, like creating marine-protected areas and banning fishing. What will it take to bring back their numbers? According to leading conservationists—including our experts at the Aquarium—the answer is hands-on help.

What's The Plan?

In 2020, the Aquarium—along with partners around the world—launched ReShark, a first-of-its-kind international coalition to restore healthy populations of threatened sharks and rays.

Our coalition’s first project is to recover Indo-Pacific leopard sharks in Indonesia. This process involves accredited aquariums breeding sharks already in human care, then transporting the resulting eggs to nurseries in Raja Ampat, Indonesia. Once hatched, the sharks are reared, tagged and released into their home waters.

Sharks and rays are endangered throughout our one world ocean, and our work with the Indo-Pacific leopard shark is the first of many ReShark species recovery projects to come.

As the coalition’s name suggests, its goal—quite literally—is to “reshark” the ocean by restoring healthy, genetically diverse and self-sustaining populations. An equally important goal is ensuring that this process is culturally respectful, co-designed and mutually implemented with local leaders in the countries where the work takes place.
