Prochilodus lineatus (synonym P. platensis) is a Central American and South American species of ray-finned fish that inhabits the basin of the Paraná River and the Paraguay River in the Argentine Mesopotamia and Paraguay, the Pilcomayo River in Bolivia, the Paraíba do Sul River in Brazil and the river San Juan in Nicaragua. In Spanish its common name is sábalo; in Brazil it receives the names curimbatá, curimba, corimbatá or grumatã. In the United States it is also known by the technical synonym Tarpon prochilodus. There are many other species of fish with the common name sábalo; P. lineatus is therefore distinguished sometimes as sábalo jetón (colloquial Spanish for "big-mouth") or chupabarro ("mud-sucker").
