چکیده

Abstract Silver Carp Hypophthalmichthys molitrix have expanded their range to encompass most of the Mississippi River basin, including much Missouri River. However, there is a paucity information concerning in especially tributaries. Little known about how function these tributaries or connectivity with main‐stem river can influence population demographics within either system. The Kansas tributary and has multiple physical anthropogenic barriers creating varying levels system, as well These connectivity, lack thereof, provide unique opportunity examine segments separated by barriers. We collected from upstream downstream first two on summers 2018 2019. No were captured hydropower dam at kilometer 84 but found water diversion weir 24. Catch rates adult lower reach above weir, caught this exhibited greater growth than below weir. juveniles also Limited via could size structure catch Lack indicates that reproduction may be limited reach, conditions more suitable for rearing juvenile Carp. This important understanding across environments, providing critical development implementation broadscale control plans.
