Marybeth Brey, PhD
I'm a research fish biologist with interests in fish movement and passage, invasive species management and ecology, and freshwater food web dynamics.
Originally from the U.P. of Michigan, I've always been interested in fisheries and freshwater; however, my interests center around the impacts of invasive species on freshwater ecosystems. I have experience working on ecosystem models and aquatic food webs, particularly related to the impacts of invasive fishes. For the past five years, I've conducted research on the movement dynamics of invasive Asian carps, both with Southern Illinois University (postdoc) and with the USGS, here in La Crosse, Wisconsin. I joined the USGS in 2015 and am currently responsible for conducting research related to movement dynamics of invasive Asian carps in the Illinois River and conducting all studies related to the use of underwater sound to deter invasive fishes in collaboration with the USACE-ERDC, USGS-CERC, and University of Minnesota-Duluth.

Invasive Carp Control: Acoustic Deterrents
Invasive carps including bighead carp ( Hypophthalmichthys nobilis), silver carp ( H. molitrix), grass carp ( Ctenopharyngodon idella), and black carp ( Mylopharyngodon piceus) are invasive fish species established throughout the Mississippi River Basin. The spread of these four species threatens the ecosystems of the Great Lakes and other major waterways. Substantial work has been done to...
Assessment of Newly Developed Acoustic Stimuli for Manipulating Movement of Bigheaded Carps in USGS Ponds
Bigheaded carps, composed of bighead ( Hypophthalmichthys nobilis) and silver carp ( H. molitrix), have specialized structures that increase their hearing range and sensitivity. Recent results from controlled laboratory studies have indicated that the playback of an outboard boat motor was effective at altering the behavior of bigheaded carps. The possibility of being able to use specific sounds...
Deployment of a Short-term Underwater Acoustic Deterrent System in the Chicago Area Waterway System
Acoustic deterrent technologies are being considered to prevent the spread of invasive carps including bighead carp ( Hypophthalmichthys nobilis) and silver carp ( H. molitrix), collectively referred to as bigheaded carps, from the Mississippi River Basin to the Great Lakes. The Illinois Department of Natural Resources, through the Invasive Carp Regional Coordinating Committee, requested the...
Field Testing of an Underwater Acoustic Deterrent System for Invasive Carps in the Illinois River
Acoustic deterrent technologies are being considered to prevent the spread of invasive carps including bighead carp ( Hypophthalmichthys nobilis) and silver carp ( H. molitrix) from the Mississippi River Basin to the Great Lakes. However, most testing has focused on experimental systems in small ponds or at large navigation locks. To further assess the effectiveness this technology in a different...
Evaluation of a BioAcoustic Fish Fence at Barkley Lock and Dam
Barkley Lock and Dam, on the Cumberland River near Grand Rivers, Kentucky, has been identified as a strategic pinch-point navigational dam for controlling invasive carps including bighead carp ( Hypophthalmichthys nobilis), silver carp ( H. molitrix), grass carp ( Ctenopharyngodon Idella), and black carp ( Mylopharyngodon piceus). Fish must pass through the Barkley lock chamber to get upstream of...
Illinois River real-time telemetry and multi-state modeling
This project supports goals and objectives of the Illinois River Monitoring and Response Work Group (MRWG) by (1) providing a real-time network of acoustic receivers to detect movements and alert key management partners of invasive carp movements beyond normal ranges (i.e., above Brandon Road Lock and Dam in the Des Plaines River), (2) coordinating partner efforts to maintain a passive 69-kHz...
Invasive Carp: Multi-Basin Movement
Invasive carp (Silver, Bighead, Grass, and Black Carp) continue to expand their range in North America, necessitating efforts to limit the spread and establishment of reproducing populations. Potential control measures include the installation of deterrents and targeted removals. Several key population bottlenecks occur at locks and dams in large rivers of North America, including locations on the...
Invasive Carp Control: Acoustic Deterrents
Invasive carp including bighead carp ( Hypophthalmichthys nobilis), silver carp ( H. molitrix), grass carp ( Ctenopharyngodon idella), and black carp ( Mylopharyngodon piceus) are invasive fish species established in the Mississippi and Ohio River basins. The spread of these species threatens the Laurentian Great Lakes and other major waterways. Significant work has been done to identify potential...
Deployment and Evaluation of an Underwater Acoustic Deterrent System at Lock and Dam 19
Previous studies and experience have demonstrated that some locks and dams operate as bottlenecks or pinch points for invasive carp populations and range expansion because of unique hydraulic conditions and operations at these dams. As compared to dams without these unique conditions, pinch-point dams restrict upstream fish passage to the lock chamber and result in limited (but not zero) upstream...
Database and web application for invasive carp telemetry data (FishTracks)
Four types of invasive carp fish species, are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade. To prevent the spread of invasive carp into the Great Lakes, the multi-agency Asian Carp Regional Coordinating Committee (ACRCC)...
Invasive Carp Integrated Control and Containment: Acoustic Deterrents for Invasive Carp
The long-term goal of this project is to develop acoustic deterrents to prevent the upstream migration of Invasive carp to the Great Lakes.
Assessment of Acoustic Stimuli for Manipulating Movement of Bigheaded Carps
Invasive Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis, hereafter referred to as bigheaded carps, have displayed a negative phonotactic response when presented with a broadband acoustic stimulus. Additional study is needed to identify effective acoustic stimuli for manipulating bigheaded carp behavior, and to test bigheaded carp responses to those stimuli in...
