Abstract

If the entire watershed of Boone County, Iowa, is considered, the same species of minnows and darters were found in the prairie streams and Des Moines River in 1972 as in 1947. Specific changes in relative abundance of minnows and darters over the 25-year period were generally correlated with habitat alteration. Habitat alteration resulting in change of bottom type allowed increase in abundance of several minnow species. Increase in water temperature and change of bottom type has contributed to the disappearance of the fantail darter from Bluff Creek. The similarity in relative abundance of fishes in 1947 and 1972 indicates that there have been few significant cases of stream habitat alteration in Boone County.
