Abstract
The lower segments of tributary streams provide the only remaining backwater habitat for much of the lower Missouri River. We describe the movements of adult channel catfish Ictalurus punctatus between a 13-km segment of the Missouri River and a tributary, Perche Creek, that enters the river in this segment to determine the extent to which river-dwelling fish use the tributary habitats. We used mark-recapture techniques to describe movements offish larger than 250 mm in total length between these habitats during a 22-month period. Most fish (59%) initially caught, recaptured, or both in the Missouri River moved into or out of Perche Creek, and most of these transient fish (72%) used the lower 8 km of the tributary. The tributary population was made up predominantly of resident fish (79%), which were initially caught and recaptured in Perche Creek. Channel catfish moved greater distances in the spring than in the fall and were more likely to move upstream in the spring and downstream in the fall. ...Keywords
