Invasive Carp

The results from this study will provide protocols for the collection, processing and analysis of environmental deoxyribonucleic acids (eDNA) samples for monitoring aquatic invasive species like Asian carp. These protocols have the potential to be used by fishery management agencies to monitor aquatic invasive species throughout the United States.

With the increasing prevalence of Aquatic Invasive Species (AIS) in the Chicago Area Waterways System (CAWS), the implementation of new control techniques to inhibit the dispersal of AIS is strongly desired. For a technique to be a truly viable option, the process would inhibit the movement of AIS between the Mississippi River Basin and the Great Lakes. A physical barrier separating these regions...

Attempts to control carp, Cyprinus carpio, populations in Minnesota (and elsewhere) date back to early 1900s (Moyle et al. 1950, Moyle and Kuehn 1964). Early efforts focused on removing large numbers of adult carp, often by targeting their winter aggregations using seine nets. Such was the strategy in Minnesota in 1930s and 40s, where carp were systematically removed with nets in dozens of lakes...

Invasive fishes are of considerable concern to aquatic resource managers. For example, the common carp (Cyprinus carpio), originally brought over from Eurasia sometime in the 1800s are now ubiquitous in U.S. waters. Although they have been around for over 100 years and have become part of U.S. culture, they are still highly detrimental to aquatic ecosystems and a method to eradicate and control of...

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 information to...

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...

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

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.

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 species...
