CarpDAT Invasive Carp Data Catalog

Four types of invasive carp fish species are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade.

TrendPowerTool: A web lookup tool for estimating the statistical power of a monitoring program to detect population trends

A simulation-based power analysis can be used to estimate the sample sizes needed for a successful monitoring program, but requires technical expertise and sometimes extensive computing resources. We developed a web-based lookup app, called TrendPowerTool, to provide guidance for ecological monitoring programs when resources are not available for a simulation-based power analysis (Fig. 1)...

Decision-support tool for managing endangered species in the face of uncertainty

Along the Santa Clara River in California, populations of the federally and state-listed Least Bell's Vireo (Vireo bellii pusillus) are recovering from near extirpation. Habitat protection and restoration, as well as reducing brood parasitism by Brown-headed Cowbirds (Molothrus ater), are thought to be the primary drivers of this recovery. The challenge going forward is to find the right balance...

Development of Sampling Protocols and Diagnostic Tools for Assessment of Freshwater Mussel Health

Assessing Impacts of Emerging and Established Diseases to Aquatic EcosystemsThe role of disease in freshwater mussel declines has been largely ignored due to the lack of appropriate diagnostic tools. Furthermore, health assessment of mussels in conjunction with restoration and propagation has not been considered during stocking and augmentation activities. This project will develop standard...

Development of a Broad Microarray Technology to Survey for Aquatic Pathogens

Assessing Impacts of Emerging and Established Diseases to Aquatic EcosystemsThe need to maintain healthy aquatic ecosystems and sustain healthy communities is greatly recognized. Aquatic pathogens pose a threat to many organisms, and being able to identify and test for an array of aquatic pathogens is important in understanding the overall health of an aquatic system. A DNA microarray tool will be...

Assessing Impacts of Emerging and Established Diseases to Aquatic Ecosystems

Native freshwater mussels play a critical role in aquatic environments and are considered “ecosystem engineers” and indicators of water quality by constantly filtering water. Populations of native freshwater mussels have declined in recent years, and this decline has been attributed to factors such as habitat degradation, pollution, and invasive species, among others. The importance of these...

Investigation Into Mass Mussel Die-off Events

Assessing Impacts of Emerging and Established Diseases to Aquatic EcosystemsThe decline of native freshwater mussels has the potential to devastate aquatic communities. Although factors such as habitat degradation, pollution, and invasive species have been linked to this decline, these potential causes cannot fully explain the large-scale mussel die-offs that have occurred in the past 20 years...

Management Tools for Dreissenid Mussels

Dreissenid mussels have posed an aquatic invasive species challenge in the United States since their arrival in the Great Lakes in the 1980s. Zebra (Dreissena polymorpha) and Quagga (D. bugensis) mussels are filter feeders with high reproductive capacity. Their behaviors result in altered nutrient cycles, shifts in trophic structures, and extirpation of some native species in systems where they...

Development of Selective Control Tools

Management Tools for Dreissenid MusselsCurrently, dreissenid mussel populations are spreading and becoming a growing problem in many aquatic systems, making it important to find management techniques that are selective for the invasive mussel populations while leaving the native populations intact.

Evaluation of Carbon Dioxide to Control Dreissenid Mussels

Management Tools for Dreissenid MusselsCarbon dioxide (CO2) has been suggested as a chemical control for a variety of invasive aquatic organisms, including Asian Carp. USGS researchers and partners evaluated the efficacy of low CO2 concentrations for preventing zebra mussel larval (veliger) settlement and during summer 2019 in a harbor of the upper Mississippi River. The lowest CO2 concentration...
