Examining deterrence potential of existing water infrastructure for limiting invasive carps movements while promoting population connectivity of native fishes

May 2023 - September 2028


Participating Agencies

  • United States Fish and Wildlife Service

There is an inherent tradeoff between limiting movements of carps with deterrents (barriers) and minimizing impacts to native fishes unless barriers are operated to allow passage of native fishes. Mismatches in the timing of large-scale movements between native fishes and carps might provide such opportunities to operate deterrents in a manner that limits carps while minimally interfering with population connectivity needed to sustain native fish populations. This work is a collaboration among Auburn University and Alabama Cooperative Fish and Wildlife Research Unit, North Carolina State University and North Carolina Cooperative Fish and Wildlife Research Unit, Mississippi State University and USGS Mississippi Cooperative Fish and Wildlife Research Unit, U.S. Fish and Wildlife Service, Mississippi Department of Wildlife, Fisheries, and Parks, U.S Geological Service’s Columbia Environmental Research Center, and U.S. Army Corps of Engineers. Information gained from this project could help operationalize numerous semi-passable barriers within the Lower Mississippi River region to maintain barrier functionality while allowing native fish passage and limiting expansion of invasive fishes.
