英文摘要	In the past few years, some countries have prohibited the removal of shark fins in an effort to protect shark populations ([ 1 ][1]). However, sharks remain at risk from this practice as long as other countries drive up demand by buying the finless shark carcasses for a cheap price ([ 2 ][2]–[ 4 ][3]). Brazil, the world's largest importer of shark meat ([ 3 ][4], [ 4 ][3]), imports finless shark carcasses and steaks from countries that are involved in the fin trade, such as China and Spain, and from Uruguay, which exports processed shark meat ([ 3 ][4], [ 4 ][3]). The growing shark meat trade in Brazil can be attributed in part to attractive prices, but the demand is complicated by mislabeled products; Brazilians are often unaware that they are eating sharks ([ 2 ][2], [ 5 ][5]). Brazil has the power to disrupt the global shark market, but it will require policies that limit shark meat imports as well as an effort to provide consumers with accurate information. In Brazil, although protected sharks cannot be legally marketed by local fishers or entrepreneurs, they can be imported without any restrictions. Moreover, it is mandatory to provide information for the proper labeling only if the imported frozen fish is in the Salmonidae family (which includes salmon and trout) or the Gadidae family (which includes cod and haddock) ([ 6 ][6]). Instead of being packaged with proper labeling, Brazil's shark meat is sold as unidentifiable carcasses or in pieces marked as cação , a deliberately ambiguous name used for multiple species ([ 7 ][7]). Despite a growing debate about shark mislabeling among nongovernmental organizations and academic communities ([ 8 ][8]), no government measures have been implemented. As a result, the consumers in Brazil remain unaware that they are purchasing shark meat and contributing to the decline of vulnerable shark species. Sharks are facing irreversible population reductions, and action is urgently needed worldwide ([ 9 ][9]), especially in Brazil ([ 10 ][10]). As a first step, Brazil's government should widely disseminate the fact that cação may refer to shark meat. The country should require all domestic and imported products to be labeled with their scientific names throughout the supply chain, ensuring accurate monitoring of the species in the system and allowing consumers to decide whether to eat a species at risk of extinction. As a result of such changes, demand would likely decrease, limiting the market for sharks with illegally removed fins. Brazil could also protect sharks worldwide by prohibiting the importation of species on Brazil's National Red List ([ 11 ][11]). Because of Brazil's outsize role in global shark trade, these changes could vastly improve conservation efforts. 1. [↵][12]1. L. Biery, 2. D. Pauly , J. Fish Biol. 80, 1643 (2012).
