Ptychocheilus

Squawfish or pikeminnows are cyprinid fish of the genus Ptychocheilus consisting of four species native to western North America. Voracious predators, they are considered an "undesirable" species in many waters. This is largely due to the species' perceived tendency to prey upon small trout and salmon. First known in western science by the common name Columbia River Dace, the four species all became lumped under the offensive name "squawfish." In 1999, the American Fisheries Society adopted "pikeminnow" as the name it recommends, because Native Americans considered "squawfish" offensive.
