The U.S. and Canada are seeking a ban in the Pacific on two fishing devices, known as wire leaders and shark lines, that have proven devastatingly effective at catching huge numbers of sharks. The Western and Central Pacific Fisheries Commission (WCPFC), which governs tuna fisheries in those waters, could vote on the proposal at its annual meeting next week in Vietnam. Banning wire leaders and shark lines would reduce fishing mortality of oceanic whitetip sharks by 40.5% and silky sharks by 30.8%, research has found.
