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 prevent upstream migration. For an acoustic deterrent ...

Invasive carps are ecologically and economically problematic fish species in many large river basins the United States pose a threat to aquatic ecosystems throughout much of North America. Four invasive carps: black carp (Mylopharyngodon piceus), grass (Ctenopharyngodon idella), silver (Hypophthalmichthys molitrix) bighead nobilis), particularly concerning for native because they occupy disrupt...

Broad-scale niche models are good for examining the potential for invasive species occurrences, but can fall short in providing managers with site-specific locations for monitoring. Using Oklahoma as an example, where invasive bighead carp (Hypophthalmichthys nobilis) are established in certain reservoirs, but predicted to be widely distributed based on broad-scale niche models, we cast bighead...

Bigheaded carps (bighead carp, Hypophthalmichthys molitrix, and silver nobilis) their hybrids play an important ecological economic role in original habitat, while introduced stocks may pose serious risks. To address questions about the persistence invasiveness of these fish, we need to better understand population structures. The genetic structures bigheaded carp populations inhabiting Lake Ba...
