Data are included for laboratory studies evaluating the thermal biology of several freshwater mussel species and their host fish including dwarf wedgemussel (Alasmidonta heterodon), brook floater (Alasmidonta varicosa), creeper (Strophitus undulatus), eastern elliptio mussel (Elliptio complanata), tesselated darter (Etheostoma olmstedi), and slimy sculpin (Cottus cognatus). Thermal endpoints include critical thermal maximum, temperature preference, oxygen consumption rates, and clearance rates of organisms acclimated to a range of temperature treatments.

Oyster reefs provide environmental and economic services within the coastal regions of the United States. Mapping the extent of these reefs and analyzing their composition can be highly beneficial for oyster management and restoration projects. The objectives of this research project included examining the feasibility of the use of low-cost side-scanning sonar (LC-SSS) systems and Unmanned Aircraft Systems (UAS) for mapping intertidal oyster reefs at selected sites within the Galveston Bay system, Texas. Two sites in Bastrop Bay and Bastrop Bayou complex were selected following defined criteria that included the existence of intertidal oyster reefs and no aviation restrictions on the operation of UAS.

1985 Gulf of Mexico Atlas abstract American oyster Crassostrea virginica Ostion americanoDescription Range: The American oyster, a bivalve mollusc of the family Ostreidae, is found in the western Atlantic from the Gulf of St. Lawrence to the Yucatan Peninsula. In the Gulf, this species occurs throughout estuaries, shallow nearshore waters, and on reefs located near river mouths. Habitat: Large populations of this benthic invertebrate are found in the large estuarine bays and sounds of the Gulf (with most concentrations found within 10-meter depths). Sedentary in character, this invertebrate attaches in clusters to shell reefs, firm mud/shell bottoms and other hard substrates. Feeding and Behavior: The American oyster...

In general, ChesMMAP is fishery-independent monitoring survey that uses a large-mesh bottom trawl to sample late juvenile-to-adult fishes in the mainstem of Chesapeake Bay. This program currently provides data on relative abundance, length, weight, sex ratio, maturity, age, and trophic interactions for several important fish species that inhabit the bay seasonally.

The U.S. Geological Survey (USGS) collected hydroacoustic data of the St. Croix River adjacent to the Osceola (WI) boat ramp for hydrographic and benthic mapping prior to the reconstruction project implemented by the National Park Service (NPS). This dataset contains predicted geologic substrate information that was interpreted from combined sonar datasets. The shapefile contains a general description of interpreted surficial bottom type with its associated class code in the attribute table. Benthic substrate maps provide important physical characteristics that can be used in habitat modeling to guide management planning of restoration and conservation efforts.

This data set includes information pertaining to 300 bivalve mollusk tissue samples collected from mollusk specimens from waters in eastern Maryland on the Delmarva Peninsula. Data includes source location, species, morphometric data, and IAV matrix gene detection status for the bivalve samples collected and analyzed in the associated study.

The U.S. Geological Survey (USGS) collected hydroacoustic data of the St. Croix River adjacent to the Osceola (WI) boat ramp for hydrographic and benthic mapping prior to the reconstruction project implemented by the National Park Service (NPS). This dataset contains reference locations that were obtained while collecting ground-truth information for geologic substrate. For statistical analysis, the locations were selected using random point sampling. The shapefile contains sample location coordinates, a general description of interpreted surficial sediment type, and an indication of mussel presence/absence in the attribute table. These geospatial locations directly correspond to the "still-images" dataset.

The Gulf Coast Vulnerability Assessment utilized expert opinion that was gathered through the Standardized Index of Vulnerability and Value (SIVVA) tool, which is an Excel-based vulnerability and prioritization tool that enables assessors to provide input in a relatively short time and allows for relatively seamless compilation of results.The vulnerability of each ecosystem and associated species was conducted by subregion, excluding those subregions where the species did not occur in significant numbers. Assessors were asked to evaluate species based on the habitats they use in a particular subregion. Because vulnerability can vary with life-stage for many species, assessors were asked to consider the most vulnerable...

Oyster reefs are one of the most important environmental and economic resources within the coastal regions of the United States. Although oyster reefs in deeper water have been mapped, the extent and condition of intertidal reefs has not been sufficiently inventoried in most states. Understanding the geographic extent and condition of intertidal oyster reef and shell bottoms is important for assessing parental stock and to determine potential recruitment bottlenecks for oysters within an estuary. These intertidal areas have traditionally served as a sanctuary from commercial harvest pressure due to closures, safety, and operational barriers preventing the harvesting of oysters in shallow water. The location...
