Extinction bites: Countries agree to protect sharks and rays
GENEVA — Countries have agreed to protect more than a dozen shark species at risk of extinction, in a move aimed at conserving some of the ocean’s most awe-inspiring creatures who have themselves become prey to commercial fishing and the Chinese appetite for shark fin soup.
Three proposals covering the international trade of 18 types of mako sharks, wedgefishes and guitarfishes each passed with a needed two-thirds majority in a committee of the World Wildlife Conference known as CITES on Sunday.
“Today we are one step closer to protecting the fastest shark in the ocean, as well as the most threatened,” said Jen Sawada, who directs The Pew Charitable Trusts shark conservation work.
The move isn’t final but is a key sign before an official decision at its plenary this week.
Conservationists applauded and exchanged hugs after the tallies. Opponents variously included China, Iceland, Japan, Malaysia and New Zealand. The U.S. voted against the mako shark measure, but supported the other two.
Rima Jabado, a shark expert and lead scientist of the Gulf Elasmo project, said many of the species included in the CITES proposals are classified as “critically endangered.” Jabado said there has been an 80% decline in the number of wedgefishes, based on available data. Like giant guitarfishes, the enigmatic wedgefish has an elongated triangle-shaped head and can be found in oceans in Southeast Asia, the Arabian Sea and East Africa.
Makos are the world’s fastest sharks, reaching speeds of up to 80 mph (nearly 130 kph). But they often get caught up in the nets of fishing trawlers hunting for tuna.
Jabado said some species of sharks and rays are becoming so difficult to find in the wild that scientists only often see them when they are on sale at local fish markets.
“How are we ever going to save these species if we only see them when fishermen bring them in?” she said, adding that even if actions are taken now, it will be decades before shark populations start to recover. Losing more sharks and rays could also have other unintended consequences since they are top ocean predators and help to balance the ecosystems, Jabado said.
Scientists warn that although warming oceans and climate change are also hurting sharks, it is the demand for shark fin soup that is threatening to drive some species to extinction. The Pew Trust estimates that between 63 million and 273 million sharks are killed every year, mostly to feed the shark fin trade centered in Hong Kong.
Dried shark fin can draw up to $1,000 per kilogram. The fins are often turned into shark fin soup, a Chinese delicacy that symbolizes good fortune, in which the gelatinous fin is served in a broth whose recipe dates back to the 10th-century Song Dynasty. Fishermen often slice off a shark’s fin while the animal is still alive before tossing the writhing carcass back into the ocean.
While Chinese celebrities like retired basketball star Yao Ming are trying to persuade diners to abandon the soup, many aren’t convinced.
“Shark fin soup is a Chinese tradition so why should I stop eating it?” Wilson Kwan said outside a seafood restaurant in London’s Chinatown. “I know some people say it’s cruel to sharks, but sharks are killers too.”
Last year, there were an estimated 66 unprovoked shark attacks on humans globally, including four fatalities, according to the Florida Museum, which tracks such incidents. It is exceedingly rare for sharks to bite humans — and when they do, it’s often because they have mistaken them for seals or other prey.
Conservationists say movies like “Jaws” have unfairly maligned society’s perception of sharks and in turn, made it difficult to garner support to protect them.
“People would be outraged if they were serving dolphins in restaurants,” said Graham Buckingham of the British shark group, Bite-Back. “But because it’s a shark, they think it’s perfectly OK.”
