Salminus, popularly known as doradoordourado, is a genus of relatively large (up to 1.3–1.4 m or 4.3–4.6 ft long[1][2]), predatory freshwater fish from the family Characidae. They are native to large tropical and subtropical rivers in South America, and undertake migrations during the rainy season to spawn.[3] They are very popular among recreational anglers and also support important commercial fisheries.[3]

Significant taxonomic confusion has surrounded this genus, and until a review in 1990, several additional species were recognised (most of these are junior synonymsofS. brasiliensis).[4] Although known for more than 150 years, S. franciscanus was only scientifically described in 2007.[3] Today, four extant (living) species are recognised:[5]
A fifth extinct species is only known from Miocene fossil remains:
