Invasive species create risks to ecological communities. Recently, in Puerto Rico, sharptooth walking catfish (Clarias batrachus) were discovered as a new invasive species. This project is using environmental DNA (eDNA) to sample streams and help inform where physical removal efforts of this invasive species could best be allocated.

Science and Products
Tennessee and Cumberland rivers longitudinal and lateral movements
Silver Carp continue to expand their range in North American river basins, necessitating efforts to limit the spread with a combination of management actions. Within the Tennessee and Cumberland River Basin, locks and dams serve as bottlenecks that slow range expansion of invasive carps. Dams in the Tennessee and Cumberland Rivers are high-head dams that restrict upstream passage to the lock...
Invasive Carp: Multi-Basin Movement
Invasive carp (Silver, Bighead, Grass, and Black Carp) continue to expand their range in North America, necessitating efforts to limit the spread and establishment of reproducing populations. Potential control measures include the installation of deterrents and targeted removals. Several key population bottlenecks occur at locks and dams in large rivers of North America, including locations on the...
Population-level modeling of bigheaded carps in the Tennessee and Cumberland Rivers
Bighead carp and silver carp (collectively known as bigheaded carps) first escaped to the Mississippi River Basin in the 1970s and by 1989 had invaded the Tennessee and Cumberland Rivers. The species threaten the economies and ecosystems for these rivers and are currently spreading upriver. USGS scientists are developing population-level models to help guide and inform control strategies and...
