| Abstract |
Tuna and billfishes are large species that have long been targeted by fisheries, whereas sharks, which are also large fishes, have tended to be considered as by-catch or nontarget species. Juan-Jorda et al. used an approach that monitors yearly changes in the International Union for Conservation of Nature Red List status to estimate population status for these three groups (see the Perspective by Burgess and Becker). After almost three decades of decline, tuna and billfishes have begun to recover because of proactive fisheries management approaches. Sharks, however, which have received much less conservation attention, have continued to decline. These results both reinforce the value of conservation and management and emphasize the need for immediate implementation of these approaches for sharks. |
