This database contains aquatic benthic macroinvertebrate abundance data derived from samples collected from 33 75-meter stream site locations within the Delaware Water Gap National Recreation area in September of 2006. The database contains two separate table files (i.e., entities) in csv format: 1) Macroinvertebrate site abundance data and 2) site location data. For macroinvertebrate data, six samples were collected within 2-3 riffle areas within each site location with Portable Invertebrate Box Samplers (0.1-m2 sample area, 350 micron mesh collecting nets). Where possible, organisms were identified to the genus taxonomic level using a stereoscope except for organisms of the family Chironomidae and class Oliogochaeta,...
Rapid advances in video technology are enabling new strategies for species abundance estimation. Here we provide estimates of fish abundance derived from video data collected in a series of stream pools in Shenandoah National Park, Virginia (n=41). Two 360-degree cameras were simultaneously used at each pool site where 15-minutes of underwater footage was collected. Environmental data are provided describing pool morphology, canopy cover, and fish cover (boulders, large woody debris, and undercut banks).

Brook trout is a species of conservation concern in the eastern US. In 2016, we evaluated brook trout movement patterns in response to food and cover treatments in an experimental stream system using RFID monitoring techniques at the USGS Leetown Science Center in Kearneysville, WV. Brook trout were tagged with 12mm HDX Passive Integrated Transponder (PIT) tags and monitored with Multi-Antenna HDX Readers within each experimental stream riffle. We collected associated data on stream temperature using HOBO temperature loggers (Onset Pro V2) and water quality parameters such as dissolved oxygen, conductivity and pH (YSI Professional Plus multiparameter instrument).

Data are included for two types of field surveys conducted for freshwater mussels within the Neversink River in the Mid-Atlantic region of the United States. Timed search (qualitative) surveys were conducted in consecutive ~200 meter sections of river in 2006 and 2007; a subset of these sections were re-surveyed qualitatively in 2009. 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 the 2009 qualitatively surveyed areas, ten ~200 meter sections of stream were selected in which to conduct quantitative surveys to estimate mussel abundance. Quantitative survey methods...

This data represents environmental attributes collected at or around field sample locations (groundwater piezometers or water wells) that were used in a study of impacts from a historic railroad embankment on wetland vegetation. GPS surveys were used to map piezometer locations, elevations, and the elevation of the ground surface in proximity to the piezometer. Water surface elevations and peat depths were measured in the field at the piezometers. Piezometer locations were also used to center a 20m x 20m vegetation survey field plot from which attributes on mean surface elevations and vegetation heights were summarized using lidar data.

This data was collected over the course of two years, from 2016 to 2017, within the flume facility laboratory. The research project that was conducted evaluated different fishway entrance designs and their effect on the passage of adult American shad. The data consists of 15 columns and 1925 rows. Each row entry pertains to the performance of a single fish during one of 64 trials over the two year period. Columns give information on the treatment condition (e.g. entrance gate designs, headwater/tailwater elevations), water quality (e.g., water temperature, turbidity), fish specific information (e.g. sex, fork length, handling), passage time, and the censor value used in the statistical analysis.

With their unique life histories, anadromous fishes require special consideration in understanding their biology and developing management strategies. During the Industrial Revolution, many populations of anadromous fishes were severely depleted or extirpated by damming, pollution or alteration of their migratory or spawning habitats. Some measures were taken in the late 1880s to provide access for anadromous fishes around dams by construction of rudimentary fishways, or by stocking fish into habitats that historically supported large runs. However, without a complete understanding of the ecology, life history and environmental needs of these species, many of these efforts failed to restore naturally reproducing...
Intersex in small- and largemouth bass has been observed in the upper Chesapeake Bay Watershed since 2003. This observation is indicative of exposure to estrogenic endocrine disrupting chemicals. In order to complement biological data sets and better identify the spatial and temporal nature of this end-point, discrete grab water samples were collected throughout the upper Chesapeake Bay Watershed for the evaluation of estrogenic activity. Data reported here are estrogenicity values derived from bioassay screening of OASIS-HLB extracts discrete grab water samples. Estrogenicity was determined using a bioluminescent yeast estrogen screen. Here we report estrogenicity data for selected sites in the Chesapeake Bay water...

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.
