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.

Developing a portable LAMP assay for detecting grass and black carp

Aquatic invasive species are a significant problem throughout the world. They cause millions of dollars in damages to industry, devastate natural ecosystems, and ruin outdoor recreational areas. Preventing their spread is imperative to preserving our natural resources. One potential pathway invasive fishes can spread is by harvesting and transporting baitfish. Often shipments of baitfish are...

Correlating seasonal trends and occupancy of bigheaded carp eDNA to land use and stream characteristics

The results of this study will advance our understanding of environmental DNA (eDNA) and how eDNA signatures change as fish behavior changes over the course of the open water season.  This will further develop eDNA as an easy sampling method to collect information about invading populations or cryptic species that are difficult to capture so that resource managers can be given better...

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

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...

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,...

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...
