The unexpectedly fast recovery speaks to the success of efforts over the past decade to end overfishing.But tuna are not the only species scientists are discussing at the 2021 World Conservation Congress in Marseille,France,which is organised by the International Union for Conservation of Nature (IUCN).Researchers caution that many other marine species remain imperiled.For instance,more than a third of the world’s sharks remain threatened with extinction due to overfishing,habitat loss,and climate change. “I think the good news is that sustainable fisheries are possible,” says Beth Polidoro,a marine biologist at Arizona State University.“We can eat fish in a proper way and without driving the population to the point where it is on the road to collapse or extinction.”At the same time,she warned that the changes in status should not be a reason to catch as many fish as we want. The IUCN,which ranks the world’s most endangered species on its Red List of Threatened Species and is backed by 16,000 experts across the globe,also announced at the meeting that some animals are moving in the other direction,onto the Red List.One notable example is the Komodo dragon,an island-living lizard at particular risk from climate change. For the better part of two decades,Polidoro has been part of a specialist group tasked with assessing the statuses of more than 60 species of tuna and billfishes for the IUCN.Her team announced its first comprehensive findings in 2011,mentioning that a number of commercially fished tuna species were dangerously close to disappearing.According to the new data,the Atlantic bluefin tuna,once listed as endangered,now qualifies for a status of least concern.As does the yellowfin tuna and albacore tuna,which were both considered near-
