The robust redhorse is a unique member of a family of fishes known as suckers. This fish had not been seen in the state's waterways for over 120 years until one was caught in the Pee Dee River in 1985, near Rockingham. Fifteen years would pass before another redhorse was captured in 2000. Pusser describes a survey of the Pee Dee River south of Richmond County to the South Carolina state line. The purpose was to locate other redhorses and to gain some insight about the their population and range. Pusser relates what was discovered.
