Aquatic Ecosystem Health
The role of the Aquatic Ecosystem Health program is to conduct research to protect, mitigate, and enhance the health of aquatic ecosystems. Research conducted within the Program is focused on the following 3 areas of study, (1) controlling aquatic invasive species, (2) fisheries restoration, and (3) understanding the impacts of contaminants on aquatic ecosystems.

Assessment of carbon dioxide as barrier to Bigheaded carp
Currently, prevention of the movement of bigheaded carps from the Mississippi watershed into the Great Lakes rests on a single electric barrier located in the Chicago Area Waterway System (CAWS). Additional barriers and/or supplements to the electric barrier would improve the efficacy of deterring bigheaded carps movement into the Great Lakes through redundancy and ‘safety nets’, and offer greater...
Relationship between fish presence and abundance in Arizona standing waters measured through standard techniques and environmental DNA
The unpredictability of DNA degradation in the environment has plagued the ability of scientists to interpret environmental DNA (eDNA) data since the technique has been used for early detection of aquatic invasive species (AIS) such as silver and bighead carps (Hypophthalmichthys molitrix and Hypophthalmichthys nobilis) throughout the Chicago Area Waterway System (CAWS), Des Plaines River, near...
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.
Use of antimycin-microparticles and alfalfa to control Grass Carp Ctenopharyngodon idella
Since their introduction in the 1960’s, grass carp ( Ctenopharyngodon idella ) have spread across the North American continent as far north as the U.S./Canadian border in the Great Lakes. Grass carp are an herbivorous species and can significantly reduce the amount of macrophytes and other plant material in a body of water. Subsequently, this can lead to many detrimental effects for certain...
