Development of a Broad Microarray Technology to Survey for Aquatic Pathogens
Assessing Impacts of Emerging and Established Diseases to Aquatic Ecosystems The 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...
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 Ecosystems The 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...
Development of Sampling Protocols and Diagnostic Tools for Assessment of Freshwater Mussel Health
Assessing Impacts of Emerging and Established Diseases to Aquatic Ecosystems The 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...
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 Mussels Currently, 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. Control technology for dreissenids in open water currently relies on a limited number of...
Evaluation of Copper as a Control Agent for Invasive Mussels
Management Tools for Dreissenid Mussels USGS researchers and partners conducted an experimental application of low dose copper, as EarthTecQZ, to a bay in Lake Minnetonka, Minnesota. The veliger density and settlement were compared to that of an untreated bay within the same lake. The copper application produced a substantial reduction in zebra mussel abundance of early life stages, juvenile...
Evaluation of Carbon Dioxide to Control Dreissenid Mussels
Management Tools for Dreissenid Mussels Carbon 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...
Effects of Carbon Dioxide on Non-Target Organisms
Invasive Carp Control: Carbon Dioxide Chemical controls are a vital component of many effective Integrated Pest Management plans. Carbon dioxide (CO2) is being evaluated as a new fishery chemical for invasive carps as a general toxicant or behavioral deterrent. Administration of non-selective chemicals, such as CO2, into public waters could pose a risk to non-target organisms (e.g. native mussels...
Carbon Dioxide for General Aquatic Invasive Species Control
Invasive Carp Control: Carbon Dioxide Carbon dioxide (CO2) is being evaluated as a new fishery chemical for general aquatic invasive species control. Most research has focused on its effectiveness as a behavioral deterrent and lethal control or invasive carps. However, because CO2 is generally non-selective, there is potential for this new control chemical to be applied across a wide range of...
Invasive Mussel Control Science: Management Tools for Assessing the Risks and Control of Invasive Dreissenid Species
Invasive zebra and quagga mussels (Dreissena polymorpha and D. rostriformis bugensis, respectively) are causing significant ecological and economic impacts and the scope of these impacts increases as they continue to spread across North America. The USGS conducts science to inform management actions for controlling and mitigating the impacts of invasive mussels. Studies include evaluation and...
Transformation methods for the glochidia of the spectaclecase mussel Cumberlandia monodonta
The spectaclecase mussel, Cumberlandia monodonta, was effectively listed as federally endangered in April 2012 (https://federalregister.gov/a/2012-5603). It is endemic to the Mississippi, Ohio and Missouri River basins and historically inhabited 44 streams in these basins (USFWS 2014). Currently, the species is known to inhabit 20 of the historical streams, five of which are represented by one or...
