The northern common shiner, Notropis cornutus frontalis, was omnivorous in its feeding, but the type of food utilized was greatly influenced by water levels. Reproduction was later in Squaw Creek than in the Des Moines River. Males had consistently higher condition factors than females. Fish grew faster in Squaw Creek than in the Des Moines River but failed to reach the length of the Des Moines River fish in their first year because of a later spawning period. Myxosporidians, nematodes, tapeworms, and copepods parasitized this species.
