These data describe the catch and biological data from 363 bottom-set gill-net lifts distributed throughout Lake Michigan (including main basin and Green Bay) between April and November in 1930–1932. Data collected from the R/V Fulmar were recorded in notebooks and are now archived at the U.S. Geological Survey’s Great Lakes Science Center. Each lift included 1–7 gangs of linen gill nets. Each gang comprised 3–5 panels each having a length of 155 m, a height of 1.5 m, and a (stretch-)mesh size of either 60, 64, 67, 70, or 76 mm. The digitization of the Fulmar data notebooks was started in the late 1990s and finished in this study.

These data were compiled for a manuscript in which 1) we develop a water temperature model for the major river segments and tributaries of the Colorado River basin, including the Colorado, Green, Yampa, White, and San Juan rivers; 2) we link modeled water temperature to fish population data to predict the probability native and nonnative species will be common in the future in a warming climate; and 3) assess the degree to which dams create thermal discontinuity in summer in river segments across the western US. Per goal #1, we developed a water temperature model using data spanning 1985-2015 that predicts water temperature every 1 mile (1.6-km) in rivers both now and in the future due to the potential influence...

This Benthic Invertebrate Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the benthic invertebrates sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), the invertebrate samples were taken from sediments remaining from the sediment analysis. Identification of the invertebrates was completed by the same invertebrate taxonomist for both the 1998-2000 evaluation and 1986-87 historical evaluation (Smith et al. 1994) for increased consistency. Oligochaetes were identified to species if possible, chironomids were identified to genus, as adult specimens are needed for specific identification, and other taxa...

Abstract (from http://www.tandfonline.com/doi/full/10.1080/00028487.2016.1150879): Long-term sampling of fisheries data is an important source of information for making inferences about the temporal dynamics of populations that support ecologically and economically important fisheries. For example, time series of catch-per-effort data are often examined for the presence of long-term trends. However, it is also of interest to know whether certain sampled locations are exhibiting temporal patterns that deviate from the overall pattern exhibited across all sampled locations. Patterns at these “unusual” sites may be the result of site-specific abiotic (e.g., habitat) or biotic (e.g., the presence of an invasive species)...

This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM high biodiversity sites (HBS) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with the areas of HBS. The HBS were derived from source data characterizing locations with concentrated at-risk biodiversity or existing source data of a prioritization exercise that identified areas of high conservation significance. It does not model actual response or condition of the HBS to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different...

Chinook salmon (Oncorhynchus tshawytscha) are an anadromous fish species that migrate through, feed in, and spawn in the Yukon River Lowlands - Kuskokwim Mountains - Lime Hills. This dataset provides the current (2013) spatial distribution of chinook salmon within the REA study area for the analysis of chinook salmon as an Aquatic Fine-Filter Conservation Element. This dataset was derived by clipping the chinook salmon distribution from the Anadromous Waters Catalog to the boundaries of the study area for this REA. The Anadromous Waters Catalog is developed and maintained by the Alaska Department of Fish and Game. It includes all waters known to include populations of anadromous fish but does not differentiate by...

Fish occurrence data have been collected within the North Slope study area, however most of these data are presently available only in non-digitized format (e.g., hardcopies, inventory reports, unpublished data, etc.). Due to the lack of spatial data available, Alaska Natural Heritage Program began collaboration with BLM fisheries biologists to assist with their efforts to enter these fish distribution datasets into the geodatabase RipFish that was developed and is maintained by BLM. Our contribution to this database serves as a final product for the Aquatic Fine-Filter CEs for the Rapid Ecoregional Assessment and will allow managers to readily have access to fish distribution data and conduct future spatial analyses....

This dataset shows the distribution of invasive aquatic species compiled from the USGS nonindigenous aquatic species database and national institute of invasive species science database. These species include asian clams, Quagga mussels, and zebra mussels.

Although future roads are included in the long-term LCM, we conducted separate spatial analyses intersecting the future layers with our fish distributions to identify the projects or watersheds with the potential to impact fish species of conservation concern. Four datasets were used to represent future road construction in the study area: preferred routes to Nome, Umiat, and Ambler; and proposed forestry roads. These roads were intersected with the distributions of Dolly Varden. The anadromous Dolly Varden habitat distribution and modeled resident Dolly Varden habitat distribution for the 2060s were combined into a single distribution for this analysis. Road intersections were highest for Dolly Varden because Dolly...

Alaska's abundant, remote, and predominantly pristine freshwater fish habitats are largely unexplored and undocumented. To begin filling these vast information gaps, the Alaska Freshwater Fish Inventory Database (AFFID) houses freshwater fish (anadromous and resident)-occurrence data sets compiled from a variety of sources. Most records in the AFFID come from Alaska Department of Fish and Game (ADFG) fish and aquatic habitat inventories. However, the AFFID also includes selected recent fish-occurrence data sets from ADFG Fish Resource Permit fish-collection reports submitted to ADFG by other organizations (agencies, consulting firms, non-governmental organizations, and individuals) who collect fish for scientific...

This dataset provides an estimate of aquatic intactness (i.e. condition or integrity) across the Bon Cuthrout Trout C's potential distribution. Current aquatic intactness estimates are based on the extent to which human impacts such as water demand, agriculture, urban development, natural resource extraction, dams, diversions, and alterations have disrupted the hydrology, water quality, and habitat quality of aquatic systems across the state of Utah and the Colorado Plateau. Aquatic intactness values will be high in areas where these impacts are low.This HUC6 (12-Digit NHD Hydrologic Unit Code) resolution dataset was created for the Colorado Plateau REA stepdown analysis using the open-source logic modeling framework...

This report presents updated information about subsistence uses of fish, wildlife, and plant resources in 5 communities of southcentral Alaska -- Iliamna, Newhalen, Nondalton, Pedro Bay, and Port Alsworth. The Division of Subsistence of the Alaska Department of Fish and Game conducted the study in collaboration with the National Park Service and Stephen R. Braund & Associates. The Pebble Project is a proposed open pit mine located 18 miles to the northwest of Iliamna and 18 miles southwest of Nondalton. The potential development of the mine requires updated baseline information about subsistence harvests and uses. Information was collected through systematic household surveys and mapping interviews. Scoping meetings...
