Fragment data from 11 nuclear microsatellite loci and sequence data from the mitochondrial cytochrome b gene were gathered from Arctic cod (Boreogadus saida) in the Beaufort and Chukchi seas. Mitogenomic analyses of Arctic cod and three other co-distributed gadoids (Polar cod [Arctogadus glacialis], Saffron cod [Eleginus gracilis], Walleye Pollock [Gadus chalcogrammus]) were also completed. Transcriptomic analyses of Arctic cod were used to identify genes associated with environmental perturbations. Genome-wide scans using RAD-Seq of Arctic cod and the co-distributed Polar Cod were collected.

Inland fishes provide important ecosystem services to communities worldwide and are especially vulnerable to the impacts of climate change. Fish respond to climate change in diverse and nuanced ways, which creates challenges for practitioners of fish conservation, climate change adaptation, and management. Although climate change is known to affect fish globally, a comprehensive online, public database of how climate change has impacted inland fishes worldwide and adaptation or management practices that may address these impacts does not exist. We conducted an extensive, systematic primary literature review to identify peer-reviewed journal publications describing projected and documented examples of climate change...

Problem - The Ithaca Subdistrict Office of the U.S. Geological Survey (USGS) is providing technical assistance to the USGS, Biological Resources Division (BRD), at the Tunison Laboratory of Aquatic Science (TLAS) in an investigation of the availability of fresh ground water. An expansion in the water supply at the laboratory is needed for a proposed spawning facility for salmon strains that are viable for natural fisheries in the Great Lakes region. The hydrogeology of the area is a complex of moraine and outwash deposits west of Cortland, N.Y. Data from existing wells at the laboratory indicate that well screens may readily clog from precipitated minerals. A review of the hydrogeology of the area, including...

These are genetic data collected from over 700 individual coho salmon (Oncorhynchus kisutch) from 17 streams and rivers within Glacier Bay Alaska and 2 rivers outside the bay. Data collected from all samples include one nuclear gene intron, Growth Hormone-1, and eight microsatellite loci.

While siltation in the areas between reservoir and riverine ecosystems can damage habitat, there is emerging evidence to suggest certain water management strategies could promote high fish diversity in these areas—but this needs to be further studied. For example, new information on young fish species in Lake Texoma, a reservoir in the Red River watershed along the Texas/Oklahoma border, will help refine the priorities of the Gulf Coast Prairie Landscape Conservation Cooperative relating to certain LCC focal species, including alligator gar and white bass.

The Kentucky Department of Fish and Wildlife Resources and Tennessee Wildlife Resource Agency conducted observations onboard commercial fishing vessels. During these observations total lengths were collected from a subset of that capture which we have used to develop a length-based stock assessment of invasive carp. The first dataset represent harvest from the invasive carp harvest program in Kentucky and Tennessee from 2009-2021 only in Lake Barkley and Kentucky Lake where the majority of harvest occurs. The second data are length data from a subset of those fish harvested in 2018-2021. The last dataset are the results from a survey delivered to fishers participating in the invasive carp harvest program in Kentucky...

Lake Texoma is home to several isolated coves walled off by sedimentation as a result of reservoir aging. The habitat fragments are relatively new features on the landscape, isolated from the reservoir and taking diverse forms. These fragments have been formed on the arms of two physicochemically distinct rivers entering Lake Texoma (Red and Washita). Fragmented coves are located within the river-reservoir interface, a highly productive and ecologically important transitional zone. We examined the structure of young-of-the-year (YOY) fish assemblages utilizing these habitats and investigated the influence of environmental factors on taxonomic and guild composition. Sampling was carried out from March through August...

Inland fisheries have tremendous cultural, economic, and subsistence value. However, climate change brings new stresses to land-locked fisheries that raise novel challenges for resource managers. One fundamental challenge in inland fisheries is how to best assess and manage data-limited fisheries when resources are finite and uncertainty is pervasive. To address this challenge, we will use quantitative models to examine whether indicators of fish population status commonly-measured by managers can serve as a “short-cut” to more data- and capacity-intensive approaches. Further, we will work and communicate directly with state and Tribal fisheries managers to better understand the challenges they face when making...

Background The New York State Department of Environmental Conservation (NYSDEC) and Adirondack Lakes Survey Corporation (ALSC) repeatedly surveyed fish assemblages and characterized water chemistry from 44 to 52 lakes during the periods 1984-1987 and 1994-2005, and 2008-2012 to document the regional effects of acidic deposition and potential recovery associated with the 1990 Clean Air Act Amendment (CAAA) under the Adirondack Long-Term Monitoring (ATLM) Project. An initial analysis of changes in fish assemblages between the periods 1984-1987 and 1994-2005 noted modest and mixed recoveries, identified five fish-community response/recovery classes, and helped to devise a fish-community index based on species acid...
American Eel (Anguilla Rostrata) Background The U.S. Geological Survey (USGS) has worked in cooperation with The Nature Conservancy (TNC) over the past 11 years to study the effects of channel geomorphology and impoundments on the distribution of common and rare mussels in the Neversink River and to characterize fish assemblages in tributaries to the Upper Delaware River in New York, Pennsylvania, and New Jersey. The focus of this research and monitoring program has recently shifted toward studies of the rapidly declining American eel (Anguilla rostrata) populations in rivers of the tri-state region. There are many factors that could potentially cause the observed declines in local and continental populations of...
Fish catch and effort data for three species caught in gill nets and trap nets between 1988 and 2019 as part of Minnesota Department of Natural Resources (MNDNR) fisheries surveys conducted during the summer and early fall are included from over 1,300 Minnesota lakes. The three fish species included are: bluegill (Lepomis marochirus) a warm-water adapted species, yellow perch (Perca flavescens) a cool-water adapted species, and cisco (Coregonus artedi) a cold-water adapted species. Additional data concerning lake characteristics and surrounding land cover were also included. Mean July lake surface temperature was calculated using simulated daily water temperatures. Watershed land use including agricultural, barren,...

The cascade of uncertainty that underscores climate impact assessments of regional hydrology undermines their value for long-term water resources planning and management. This study presents a statistical framework that quantifies and propagates the uncertainties of hydrologic model response through projections of future streamflow under climate change. Different sources of hydrologic model uncertainty are accounted for using Bayesian modeling. The distribution of model residuals is formally characterized to quantify predictive skill, and Markov chain Monte Carlo sampling is used to infer the posterior distributions of both hydrologic and error model parameters. Parameter and residual error uncertainties are integrated...

Submersed aquatic vegetation, a critical component of highly productive coastal ecosystems, is greatly affected by sea level rise. The Gulf Coast Prairie Landscape Conservation Cooperative needs consistent information on these natural resources along the Gulf of Mexico Coast to develop computer modeling tools. These tools will contribute to efforts to forecast the effects of climate change on the distribution, abundance, and diversity of submersed aquatic vegetation and the fish and wildlife that depend on them. This project was co-funded by the Gulf Coast Prairie and the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperatives and the South Central Climate Adaptation Science Center. An alternate reference...
