A new international organization, ReShark, including partners from 15 countries and 44 aquariums, is challenging the shark statistics. According to National Geographic, ReShark's goal is to release 500 endangered zebra sharks in Indonesian waters to increase a wild population that is on the edge of extinction. This is the first-ever attempt to reintroduce captive sharks into the wild.
Marine reintroductions present significant challenges due to the complexity and shortage of ocean life, as well as the difficulty in managing threats, according to National Geographic. Team ReShark understands that the reintroduction may go up in smoke. Unlike land animals that have been successfully reintroduced in the past, such as giant pandas in China, young sharks are more likely to suffer from diseases and be killed by other animals, and they struggle to find food on their own.
Sharks have a remarkable history as one of the oldest vertebrate species, surviving five mass extinctions over a period of 420 million years. They play an important role in marine ecosystems by influencing the ocean's food chains. However, they are now facing the second-highest rate of disappearance. Research shows that more than 37 percent of the shark species are at risk of extinction due to overfishing, both legal and illegal. Sharks are hunted for their meat. Nearly 100 million sharks are killed by human hands each year, according to the organization Sentient Media.
Despite the alarming decline in shark populations globally, top shark scientists are hopeful that ReShark's efforts will succeed. Given these challenges, Simon Fraser University ecologist Dulvy initially had some doubts about ReShark's plans. However, after asking some questions, he was surprised by what the initiative could produce. "This initiative is different," Dulvy explained. Similarly, Rima Jabado, Dulvy's successor, recognized ReShark as a unique project that could provide a lifeline for endangered shark species. "It may provide an opportunity for species not to go extinct," she said.
