Conservation Status

The World Conservation Union (IUCN) lists forty-three species in Perciformes as Extinct, five as Extinct in the Wild, fifty-five as Critically Endangered, twenty-eight as Endangered, 135 as Vulnerable, five as Conservation Dependent, and forty as Near Threatened. Extinct means no longer in existence. Extinct in the Wild means no longer alive except in captivity or through the aid of humans. Critically Endangered means facing extremely high risk of extinction in the wild. Endangered means facing very high risk of extinction in the wild. Vulnerable means facing high risk of extinction in the wild. Conservation Dependent means if the conservation program were to end, the animal would be placed in one of the threatened categories. Near Threatened means at risk of becoming threatened with extinction in the future.

The U.S. Fish and Wildlife Service lists fourteen Perciformes species as Endangered and seven as Threatened. Endangered means in danger of extinction throughout all or a significant portion of its range. Threatened means likely to become endangered in the near future.
