|Progress and Results
Large rivers in Kansas have been severely altered by habitat modification, altered hydrology, channelization, dam construction, pollution, and many fish species are declining because of these alterations. Recruitment is a critical factor in large river fishes because anthropogenic influences can destroy of modify spawning and juvenile rearing habitat (e.g. backwaters), block fish migrations, or otherwise limit recruitment. In addition, biotic factors such as predation, food availability, or competition may affect recruitment. Therefore, research to determine factors that influence recruitment of riverine fishes would aid managers in determining the critical factors that limit recruitment to possible mitigation or conservation efforts (e.g., habitat enhancements, minimum flow requirements, modifications of reservoir operations) that would help native river fishes.
This project began in January 2008 and will continue with at least three field seasons of fish sampling. Joe Gerken was selected at the Ph.D. student on the project and began in January 2008
