Marybeth Brey, Ph.D.
I'm a research fish biologist with interests in fish movement and passage, invasive species management and ecology, and freshwater food web dynamics.
Biography
Education:
- Ph.D. 2012 North Carolina State University, Zoology
- M.S. 2006 Eastern Illinois University, Biological Sciences
- B.S. 2004 Central Michigan University, Biology
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, particually 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, WI. 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 Univeristy of Minnesota-Duluth.

Asian Carp Integrated Control and Containment: Acoustic Deterrents for Asian Carp
The long-term goal of this project is to develop acoustic deterrents to prevent the upstream migration of Asian 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...
Assessment of newly developed acoustic stimuli for manipulating movement of bigheaded carps
Bigheaded carps, like other cyprinids, have specialized structures known as Weberian ossicles that increase their hearing range and sensitivity. Recent results from controlled laboratory studies have indicated that playback of a recording of an outboard boat motor was effective at altering silver and bighead carp behavior.
Bioacoustic manipulation of invasive Bigheaded carp
Bigheaded carp, especially silver (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis), are invasive fish species that have established breeding populations dominating large regions of the Mississippi Drainage in the 20 years following escape from aquaculture facilities in Arkansas
Application of broadband sound for bigheaded carp deterrence
Bigheaded carp, especially silver (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis), are invasive fish species that have established breeding populations dominating large regions of the Mississippi Drainage in the 20 years following escape from aquaculture facilities in Arkansas.
Early generation hybrids may drive range expansion of two invasive fishes
1. Introgressive hybridization between two invasive species has the potential to contribute to their invasion success and provide genetic resiliency to rapidly adapt to new environments. Additionally, differences in the behaviour of hybrids may lead to deleterious ecosystem effects that compound any negative impacts of the invading parental...
Coulter, Alison A.; Brey, Marybeth; Lamer, James T.; Whitledge, Gregory W.; Garvey, James E. Evaluation of an acoustic fish deterrent system in shallow water application at the Emiquon Preserve, Lewistown, IL.
Expansion of non-native fish have caused ecological and economic damage and can negatively impact native fish populations. Current research on deterrent technologies for bighead Hypophthalmichthys nobilis and silver carp H. molitrix have primarily focused on reducing upstream movement in large river lock approaches. However,...
Wamboldt, James; Murchy, Kelsie A.; Stanton, J.C.; Blodgett, K. Douglas; Brey, Marybeth Multistate models of bigheaded carps in the Illinois River reveal spatial dynamics of invasive species
Knowledge of the spatial distributions and dispersal characteristics of invasive species is necessary for managing the spread of highly mobile species, such as invasive bigheaded carps (Bighead Carp [Hypophthalmichthys nobilis] and Silver Carp [H. molitrix]). Management of invasive bigheaded carps in the Illinois River has focused on using human-...
Coulter, Alison A.; Brey, Marybeth; Lubejko, Matthew; Kallis, Jahn L.; Coulter, David P.; Glover, David C.; Garvey, James E.; Whitledge, Gregory W. Reexamining the frequency range of hearing in silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp
Silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp (collectively bigheaded carp) are invasive fish that threaten aquatic ecosystems in the upper Midwest United States and the Laurentian Great Lakes. Controlling bigheaded carp is a priority of fisheries managers and one area of focus involves developing acoustic deterrents to...
Vetter, Brooke J.; Brey, Marybeth; Meninger, Allen F. Evaluating upstream passage and timing of approach by adult bigheaded carps at a gated dam on the Illinois River
Dams are a conservation threat because they function as barriers to native fish movement; however, they may prevent the spread of invasive species. Invasive bigheaded carps (Hypophthalmichthys spp.) threaten the Great Lakes ecosystem and are advancing towards Lake Michigan via the Illinois River. Navigation dams on the Illinois River may...
Lubejko, Matthew; Whitledge, Greg; Coulter, Alison A.; Brey, Marybeth; Oliver, Devon; Garvey, James E. An integral projection model with YY-males and application to evaluating grass carp control
Invasive fish species disrupt ecosystems and cause economic damage. Several methods have been discussed to control populations of invasive fish including the release of YY-males. YY-males are fish that have 2 male chromosomes compared to a XY-male. When YY-males mate, they only produce male (XY) offspring. This decreases the female proportion of...
Erickson, Richard A.; Eager, Eric A.; Brey, Marybeth; Hansen, Michael J.; Kocovsky, Patrick USGS Integration of New Science and Technology, Appendix A
This product summarizes the USGS plans for integration of new science and technology into Asian Carp control efforts for 2017. This includes the 1) implementation and evaluation of new tactics and behavioral information for monitoring, surveillance, control and containment; 2) understanding behavior and reproduction of Asian carp in established...
Brey, Marybeth; Knights, Brent C.; Cupp, Aaron R.; Amberg, Jon J.; Chapman, Duane C.; Calfee, Robin D.; Duncker, James J. Restoration versus invasive species: Bigheaded carps’ use of a rehabilitated backwater
Knowledge of how invasive species use invaded habitats can aid in developing management practices to exclude them. Swan Lake, a 1100-ha Illinois River (USA) backwater, was rehabilitated to restore ecosystem functions, but may provide valuable habitat for invasive bigheaded carps [bighead carp (Hypophthalmichthys nobilis) and silver carp (H. ...
Coulter, Alison A.; Schultz, Douglas; Tristano, Elizabeth; Brey, Marybeth; Garvey, James E. Not all carp are created equal: Impacts of broadband sound on common carp swimming behavior
Bighead carp (Hypophthalmichthys nobilis), silver carp (H. molitrix) (hereafter: bigheaded carps), and common carp (Cyprinus carpio) are invasive fish causing negative impacts throughout their North American range. To control their movements, non-physical barriers are being developed. Broadband sound (0.06 to 10 kHz) has shown potential as an...
