But the commission does not set catch limits for sharks. Most kinds of sharks are caught accidentally by vessels hunting for tuna and tunalike species, although a few species, such as shortfin makos, are targeted directly for their meat and large fins. Although conservationists failed to win new protectionsfor threatened sharks in the Atlantic Ocean at ICCAT¡¯s annual meeting, which concluded last week, they hope to make significant progress over the next few years as changes to the treaty are negotiated.
