An age and growth study was made of 705 quillback, Carpiodes cyprinus, and 399 highfin carpsuckers, C. velifer, taken from the Des Moines River, Boone County, Iowa, from June 1 to August 24, 1960. The length-weight relationship, body-scale relationship and coefficient of condition of these two species are very similar, but the quillback is a larger and faster growing fish. Difficulty was encountered in distinguishing young quillbacks and highfins from the young of the other two species of carpsuckers found in the river.
