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.

A laboratory study was conducted at the Northern Appalachian Research Laboratory (Wellsboro, PA) on the ability to manipulate photoperiod and water temperatures to determine its effects on Eastern elliptio freshwater mussel glochidia production. Brooding mussels were collected from Pine Creek, Tioga County, PA in late December and were housed in the laboratory in groups subjected to one of four environmental treatments: natural temperature and photoperiod, 6 week delay in natural conditions, 12 week delay in natural conditions, and natural temperature and photoperiod with a winter low of 10°C. In this study, "natural" conditions refer to light and temperature conditions that mimic what mussels would have been exposed...

To identify potential biomarkers of salt stress in the freshwater mussel Elliptio complanata, we examined transcriptional responses of the common mussel Elliptio complanata to controlled NaCl exposures. The data set is a table of counts, with the rows being the transcripts detected in the samples in the experiment and the columns identifying the samples. Four mussles were exposed to normal freshwater and four mussels were exposed to high salinity (two ppt), for a period of seven days.

Data are included for two types of field surveys conducted for freshwater mussels throughout the Susquehanna River Basin (and one site in the Potomac River Basin) in the Mid-Atlantic region of the United States from 2008-2010. Timed search (qualitative) surveys were conducted in consecutive ~200 meter sections of river (at least 8 in each stream). The number of mussels of each species and associated search time were recorded for each survey section to determine a catch per unit effort (CPUE; number of individuals found per person hour). Within qualitatively surveyed areas, one ~200 meter section of stream was selected in which to conduct quantitative surveys to estimate mussel abundance, assess presence of juvenile...

Data were collected on American glass eels (Anguilla rostrata) to determine optimal thermal conditions for laboratory rearing and aquaculture. American glass eels (Anguilla rostrata) were housed in buckets for 3 weeks at 14, 18, 22, or 26°C (n=5 buckets/treatment) to determine optimal juvenile rearing temperature in the laboratory. Initial weight (g) was recorded for each bucket. During the 3 week experimental period, data was collected on water temperature (°C), mortality, and the presence of gas bubbles. Water samples were taken to measure ammonia (mg/L) following the completion of the experiment. Final eel length (mm) and wet weight (g) were recorded for all eels in the study.
