Shark advocates at Oceana recently sued the National Marine Fisheries Service (NMFS), claiming that the way the agency controls fishing on dusky sharks violates the Magnuson-Stevens Act.  Duskies are overfished and have suffered overfishing for years, even though it is illegal to retain them if they are caught.  The duskies’ plight highlights the shortcomings of bans and similar efforts when it comes to protecting vulnerable species like sharks, especially when they are caught alongside other, healthier species.

Over the last several years, more and more people have learned about both the importance of sharks and the ongoing threats to their existence. This is great news because sharks are among the most important creatures in the ocean, playing a vital role in maintaining healthy marine ecosystems.  Plus, they’re really cool.  Formerly of interest exclusively to fish geeks like myself, Shark Week is now a widely celebrated summer ritual.  Shark finning, a deplorable practice where a shark’s fin is removed and the rest of its body is discarded at sea, has been banned in the United States since 2000, and more than 70 other countries have enacted similar bans.

Despite this progress, shark populations remain threatened and overfishing is common. The FAO reports that the market for sharks has actually increased, and many sharks die as bycatch as a side effect of fishing for other species at healthier population sizes, such as Atlantic swordfish (which has recovered after a focused conservation effort).
