November 28, 2022 — Famed undersea explorer Jacques Cousteau had a favorite shark: the oceanic whitetip, or Carcharhinus longimanus. He said they were the most dangerous of all sharks, more so than the great white (Carcharodon carcharias).
Some researchers believe the species used to be one of the world’s most abundant vertebrates longer than 6 feet (1.8 meters).
Today, however, the animal is one step away from extinction, pushed to the brink by overfishing.
While sharks are often pulled up accidentally by boats hunting other fish, especially tuna, many vessels target them intentionally, hoping to harvest their fins, meat, and, sometimes, their teeth and internal organs. Such vessels often make use of special tools known as wire leaders and shark lines, whose use is minimally regulated by the multilateral bodies that govern international fishing grounds.
Now, those devices may finally face a reckoning.
In a bid to save the oceanic whitetip, the U.S. and Canada have asked the Western and Central Pacific Fisheries Commission (WCPFC), which governs tuna fisheries in those waters, to prohibit the use of wire leaders and shark lines.
The WCPFC could vote on the proposal at its annual meeting, to be held next week in Da Nang, Vietnam.
