Carbon dioxide has shown promise as a tool to control movements of invasive Asian carps. We evaluated lethal and sublethal responses of juvenile fat mucket (Lampsilis siliquoidea) mussels to carbon dioxide concentrations (43–269 mg/L, mean concentration) that are effective for deterring carp movement. The 28-d LC50 value (lethal concentration to 50% of the mussels) was 87.0 mg/L (95% confidence interval, CI 78.4–95.9) and at 16-d post-exposure was 76.0 mg/L (95% CI 62.9–90.3). A proportional hazards regression model predicted that juveniles could not survive CO2 concentrations >160 mg/L for more than 2 weeks or >100 mg/L CO2 for more than 30 days. Mean daily shell growth was significantly lower for mussels that...

In Texas, the USFWS is currently reviewing 11 mussel species for ESA protection and several of these species (e.g., Cyclonaias petrina, Texas Pimpleback, and Lampsilis bracteata, Texas Fatmucket) have been the primary focus of controlled propagation by several federal hatcheries. To date, information on genetic diversity within and across known populations for these species is incomplete and so the justification for their controlled propagation is unclear, and a genetic management plan to guide propagation activities does not exist. These unknowns raise serious questions about whether any of the 11 proposed species are truly in need of and would benefit from controlled propagation. The overall goal of this project...

Marine mussels are a ubiquitous and crucial component of the nearshore environment, and new genomic technologies exist to quantify molecular responses of individual mussels to stimuli, including exposure to polycyclic aromatic hydrocarbons (PAHs). We used gene-based assays of exposure and physiological function to assess lingering oil damage from the 1989 Exxon Valdez oil spill using the Pacific blue mussel, Mytilus trossulus. We developed a diagnostic gene transcription panel to investigate exposure to PAHs and other contaminants and their effects on mussel physiology and health. Mussels were collected annually from 2012 through 2015 at five field sites (mussel beds) in western Prince William Sound: Herring Bay,...

The database includes point and stream reach locations of imperiled mussels identified by federal and state governments, universities, and museums in the states of Louisiana, Oklahoma and Texas. Point locations are linked to stream reaches of the National Hydrography Dataset (NHD). Also in this database is the imperiled mussel presence in HUC12 watersheds in Oklahoma from the Watershed Boundary Dataset downloaded on 20150318. This dataset presents the locations of all mussels identified as a Species of Greatest Conservation Need (SGCN) assembled by the Oklahoma Department of Wildlife Conservation for the Oklahoma Natural Heritage Program. Throughout the remainder of these metadata, this group of organisms will be...

This dataset provides individual measurements of toxicity and water quality data used to calculate means reported in the associated publication. The objectives of the present study were to (1) refine test conditions for improving mussel survival and growth in a long-term feeding study, (2) evaluate chronic toxicity of NaCl and KCl to fatmucket under traditional test conditions outlined in ASTM (ASTM 2017) and the refined test conditions, and (3) assess the influences of test durations, starting ages of organisms, and the presence of sand substrate on the sensitivity of juvenile fatmucket to NaCl in chronic exposures under refined test conditions. Multiple tests were conducted to determine the chronic toxicity of...

Appendix 4.26, 4.31, 4.32, and 4.33 in Kentucky's Comprehensive Wildlife Conservation Plan. Each taxonomic conservation area (6 total) was assigned a value of 1 and then all were summed together. Ecoregions with values of 4 or more were considered tier I areas

The southeast United States’ rivers and streams support the most diverse unionid (freshwater mussel) fauna on earth. These species are a focus of the GCP LCC because their sensitivity to habitat degradation, fish community changes, and changes in water quality and quantity make them akin to the proverbial ‘canary in the coal mine.’ They are essential components of riverine ecosystems, influencing nutrient cycling and macro-invertebrate diversity. Their decline during the past century stems from overharvest, water pollution, habitat fragmentation, and introduction of nonindigenous predators and exotic mollusks; however, habitat degradation has been the most influential.

The objectives of the present study were to develop methods for propagating western pearlshell (Margaritifera falcata) for laboratory toxicity testing and evaluate acute and chronic toxicity of chromium VI [Cr (VI)] to the pearlshell and a commonly tested mussel (fatmucket, Lampsilis siliquoidea at 20°C or in association with a co-stressor of elevated temperature (27°C), zinc (50 µg Zn/L), or nitrate (35 mg NO3/L). A commonly tested invertebrate (amphipod, Hyalella azteca) was also tested in chronic exposures.

Spatial patterns in mussel richness and endemism (i.e., weighted and corrected weighted endemism) at stream reach, HUC4, HUC6, and HUC8 spatial scales were characterized. Stream SR was estimated by summing the total number of mussel species predicted within each stream. Stream-level weighted endemism was calculated by weighting each species’ presence in the stream by the inverse of the total number of streams it was predicted to occupy, then summing across all species predicted present within the stream. This biodiversity metric therefore provides context about the range extent of the species predicted within the stream (e.g., higher values indicate either high richness or the presence of several range-restricted...

Rivers and streams of the southeastern United States support the most diverse unionid (freshwater) mussel fauna on earth. Unionids are essential components of riverine ecosystems, often dominating benthic biomass and influencing nutrient cycling and macro-invertebrate diversity. Unionids are one of the most endangered groups of freshwater organisms in the United States. The decline of native freshwater mussels during the past century has resulted from a variety of factors including overharvest, water pollution, land use alteration, and the introduction of invasive species. However, the most influential anthropogenic factor impacting unionids has been habitat degradation. Another factor that compounds efforts to...
