A STUDY OF THE EFFECTS OF STREAM CHANNELIZATION AND BANK STABILIZATION ON WARMWATER SPORT FISH IN IOWA: SUBPROJECT NUMBER 5. EFFECTS OF LONG-REACH STREAM CHANNELIZATION ON DISTRIBUTION AND ABUNDANCE OF FISHES

Relationships between habitat characteristics and the distribution and abundance of fishes were studied in 11 natural and channelized warm-water stream segments of the upper Des Moines River basin during the summers of 1974 and 1975. Fishes were collected by electroshocking. Fifty-one species of fishes from 11 families were collected. The species diversity index tended to be depressed at high water levels and in situations of high turbidity, reflecting lower sampling efficiency under such conditions. Species diversity, measured both in terms of numerical abundance and biomass, was generally greatest in unchannelized woodland stream segments.
