The effects of 28-day exposure to elevated C02 on survival, growth and condition of the juvenile life stage of Lampsilis siliquoidea and Lampsilis higginsii mussels
In study AEH-14-COr02, Lampsilis siliquoidea juveniles were exposed to four treatments of CO2, ranging from 43 to 266 mg/L, for 28 days, followed by 17 days post-exposure in untreated water. The resultant median lethal concentration of CO2 that caused 50% mortality (LC50) was 78 ±13 mg/L. The targeted field concentration of a CO2 barrier is 70-80 mg/L. The present study intends to repeat the...
Evaluation of lethal and sublethal responses of dreissenid and unionid mussels to elevated carbon dioxide
Control technology for dreissenid mussels currently relies heavily on chemical molluscicides that can be both costly and ecologically harmful. There is a need to develop more environmentally neutral control tools to manage dreissenid mussels. Carbon dioxide has shown toxicity to several species of invasive bivalves, including zebra mussels (Dreissena polymorpha) and the Asian clam (Corbicula...

Characterization of occurrence and abundance of targeted metabolites in unionid mussels from three streams Characterization of occurrence and abundance of targeted metabolites in unionid mussels from three streams
The data consists of targeted metabolite analysis (using quadrupole time-of-flight mass spectroscopy;UHPLC-QTOF-MS) of hemolymph from two freshwater mussel species (Lampsilis cardium and L. siliquoidea) from three streams in Indiana. Concentrations of metabolites were modeled by species, stream and sex to determine the influence of each parameter.
Bacteria identified in freshwater mussels in the Clinch River, VA, associated with mortality events from 2018 to 2020 Bacteria identified in freshwater mussels in the Clinch River, VA, associated with mortality events from 2018 to 2020
We investigated the cultureable bacterial communities in the native freshwater mussel faunal in the Clinch River, VA/TN during mussel mortality events in 2018, 2019 and 2020 and examine the spatial and temporal distribution of bacterial genera among Pheasantshells and six other unionid species.
A Novel Gonadotropic Microsporidian Parasite (Microsporidium clinchi n. sp.)

Infecting a Declining Population of Pheasantshell Mussels (Actinonaias pectorosa) (Unioinidae) from the Clinch River, USA
Freshwater mussels of the order Unionida are among the most endangered animal groups globally, but the causes of population declines are often enigmatic with little known about the role of disease. In 2018, we collected wild adult pheasantshell (Actinonaias pectorosa) and mucket (Actinonaias ligamentina) during an epidemiologic survey investigating an ongoing mussel mass mortality event...
Use of Carbon Dioxide to Prevent Settlement of Dreissenid Mussels Use of Carbon Dioxide to Prevent Settlement of Dreissenid Mussels
Dreissenid management has focused primarily on chemical tools which are efficacious, but not without ecological or economic costs. There is a need for additional control tools that are less expensive, readily available, and will not leave a residue after treatment. Carbon dioxide has these advantages over chemical pesticides and has demonstrated effectiveness for control of a range of...
Assessments of the binary mixtures of four toxicants on Zebra Mussel (Dreissena polymorpha) mortality, data release Assessments of the binary mixtures of four toxicants on Zebra Mussel (Dreissena polymorpha) mortality, data release
This dataset captures the Zebra Mussel dose-response to four independent toxicants and each binary mixture of those toxicants. Toxicants included EarthTec QZ, Clam-Trol CT-2 (syn. Spectrus CT1300), niclosamide, and potassium chloride. Each dose of toxicant was verified with either ICP-OES or UHPLC, depending on analyte, and comparison to a standard curve. Mortality was tabulated for each
Assessment of uncontained Zequanox applications in a Midwestern lake data Assessment of uncontained Zequanox applications in a Midwestern lake data
We applied Zequanox using a custom-engineered, boat mounted application system to replicated 0.30 Hectare plots within a small inland lake. The objectives of these applications were to determine if uncontained, open-water Zequanox applications could effectively control zebra mussel populations and protect native unionid mussel populations within zebra mussel infested systems.

Toward invasive mussel genetic biocontrol: Approaches, challenges, and perspectives Toward invasive mussel genetic biocontrol: Approaches, challenges, and perspectives
Invasive freshwater mussels, such as the zebra (Dreissena polymorpha), quagga (Dreissena rostriformis bugensis), and golden (Limnoperna fortunei) mussel have spread outside their native ranges throughout many regions of the North American, South American, and European continents in recent decades, damaging infrastructure and the environment. This review describes ongoing efforts by...

Biologists monitoring freshwater mussel (order Unionida) populations rely on behavioral, often subjective, signs to identify moribund (“sick”) or stressed mussels, such as gaping valves and slow response to probing, and they lack clinical indicators to support a diagnosis. As part of a multi-year study to investigate causes of reoccurring mortality of pheasantshell (Ortmanniana pectorosa...

Open water dreissenid mussel control projects: Lessons learned from a retrospective analysis Open water dreissenid mussel control projects: Lessons learned from a retrospective analysis
Dreissenid mussels are one of the most problematic aquatic invasive species (AIS) in North America, causing substantial ecological and economic effects. To date, dreissenid mussel control efforts in open water have included physical, biological, and chemical methods. The feasibility of successful dreissenid mussel management or eradication in lakes is relatively undocumented in the...

Targeted metabolomics characterizes metabolite occurrence and variability in stable freshwater mussel populations Targeted metabolomics characterizes metabolite occurrence and variability in stable freshwater mussel populations
Freshwater mussels (order Unionida) play a key role in freshwater systems as ecosystem engineers and indicators of aquatic ecosystem health. The fauna is globally imperilled due to a diversity of suspected factors; however, causes for many population declines and mortality events remain unconfirmed due partly to limited health assessment tools. Mussel-monitoring activities often rely on...

Recent bacteriological investigations of freshwater mussel mortality events in the southeastern United States have identified a variety of bacteria and differences in bacterial communities between sick and healthy mussels. In particular, Yokenella regensburgei and Aeromonas spp. have been shown to be associated with moribund mussels, although it remains unclear whether these bacteria are...

Further bacteriological analysis of annual Pheasantshell (Actinonaias pectorosa) mussel mortality events in the Clinch River (Virginia/Tennessee), USA, reveals a consistent association with Yokenella Regensburgei Further bacteriological analysis of annual Pheasantshell (Actinonaias pectorosa) mussel mortality events in the Clinch River (Virginia/Tennessee), USA, reveals a consistent association with Yokenella Regensburgei
Pheasantshell (Actinonaias pectorosa) mussels in the Clinch River (Tennessee/Virginia, USA) have declined dramatically in recent years. The bacterium Yokenella regensburgei was first isolated with high prevalence from Pheasantshells during the peak of a 2017 mortality event, but it was not identified after mortality subsided a few months later. Since 2017, Pheasantshell mortality in the...

Researchers most often focus on individual toxicants when identifying effective chemical control agents for aquatic invasive species; however, toxicant mixtures may elicit synergistic effects.
