This data set documents the dry mass energy density, distribution, and stomach contents of age-0 chum salmon (Oncorhynchus keta) captured in the Kuskokwim Bay estuary in May and June 2004. The analysis of this data was published in Burrill et al. 2018 (DOI :10.1007/s00300-018-2297-2.).
This dataset contains two tables comprising catch per unit effort (CPUE) data and length measurements from fish surveys conducted in the nearshore Beaufort Sea, Alaska, between 1988 and 2019. Historical data collected by the U.S. Fish and Wildlife Service (USFWS) includes fish catch and fish length data (measured from a subset of the total catch) from two eras, 1988-1991 and 2003-2005, in the eastern Beaufort Sea (Arctic National Wildlife Refuge). Similar data was collected by the U.S. Geological Survey (USGS) from a subset of the historical eastern Beaufort Sea sites and some additional central Beaufort Sea (Simpson Lagoon and Stefansson Sound) sites more recently, 2017-2019. Here we have compiled and standardized...
The dataset is the daily count of Sockeye Salmon (Oncorhynchus nerka) passing through a fish counting weir on the Pilgrim River from 2003 to 2014. Also, included in the data set is the daily temperature and river height measured at the weir (65.103071°, -164.824046°).The fish weir was operated during the summer (late June to mid-September) by the Norton Sound Economic Development Corporation.
This dataset contains isotope results of stable isotope (δ13C and δ15N) and radicoarbon (F14C) analyses of muscle tissue from fish collected in the nearshore Beaufort Sea, Alaska in summers 2017-2019.
This dataset provides nine tables of data from an experimental study in which juvenile Coho Salmon (Oncorhynchus kisutch) were reared in floating net pens (limnocorrals) and exposed to Elodea spp. (a potential invasive species in high latititude lakes) and native aquatic vegetation. Data include: (1) coho salmon body, otolith, and stable isotope measurements, (2) abundance of macroinvertebrates, (3) zooplankton, (4) periphyton, (5) aquatic vegetation, (7) measurement of chlorphyll A, (8) dissolved oxygen, and (9) water temperature.
This data set documents the stomach contents of age-0 Arctic cisco (Coregonus autumnalis) captured in Prudhoe Bay, Alaska in August 2009. The analysis of this data was published in von Biela et al. 2013 (Polar Biology 36:137-146, doi:10.1007/s00300-012-1244-x). The data consists of counts of specific zooplankton taxa from individual fish stomachs.

This dataset provides annual summaries of information on age-0 sablefish in Rhinoceros Auklet (Cerorhinca monocerata) chick diets from Middleton Island, Alaska. This includes number of diet samples, number of sablefish sampled, proportion of total biomass, catch per unit effort, and frequency of occurrence for each year. We calculated an annual growth index for age-0 sablefish using the relationship between mean length by day and Julian day for each year (OLS[F = 24.44, df = 61, 184]: R^2 = 0.85, p < 0.001). From this model, growth (in mm per day) is the slope, and predicted length (in mm) is the length on the median Julian day = 205 (July 24). Annual anomalies of growth and length are calculated for each variable...
This data set is four tables with: 1) the body condition and egg counts of Sockeye Salmon captured at several sites along the Pilgrim River 2013-2016, 2) water temperature from 10 automated temperature dataloggers during the summers of 2013-2016, 3) results from an experiment to determine the effect of elevated water temperature on levels of Heat Shock Protein (HSP70) in captive juvenile Sockeye Salmon and 4) the geographic coordinates of temperature dataloggers and fish capture sites.
These data are a compilation of geographically widespread observations of premature mortality in Pacific salmon across their range in Alaska in 2019. Premature mortality observations primarily spanned an area of western and southcentral Alaska that is approximately one million km2 and included all five species of Pacific salmon. Observations were obtained and compiled in a single database from four sources including reports to a citizen science reporting network (LEONetwork.org), from Alaska Department of Fish and Game's Arctic-Yukon-Kuskokwim region by community members or staff, traditional media and social media, and directed emails by the lead author. Occasional observations of species other than Pacific salmon...
This data set documents the gene transcription levels for a panel of 12 selected genes and the heat shock protein 70 (HSP70) protein abundance measured in the muscle tissue of individual wild Chinook salmon captured from locations within the U.S. portion of the Yukon River watershed. Chinook salmon were primarily captured in 2016 and 2017 from existing field efforts (n = 477). A small number of additional samples (n = 22) were collected in 2018 following an experimental temperature experiment conducted in Pilot Station, AK, USA. During this experiment individual fish were held for ~6 hours at either river ambient control water temperatures or a heated treatment temperature of 18 °C or 21 °C. This small experiment...
This data set documents the temperature and dissolved oxygen of water during the implementation of a new experimental thermal challenge protocol for migrating adult Pacific salmon in remote settings. This experiment was conducted with migrating adult Chinook salmon near Pilot Station, Alaska, along the Yukon River in a location without access to utilities. The analysis of this data was published in Donnelly et al. 2020 (DOI:10.1093/conphys/coaa074).
This dataset consists of two tables with the results from two manipulative thermal experiments with juvenile coho salmon (May 2021) and juvenile Chinook salmon (May 2020) and include 1) gene transcription results and heat shock protein 70 abundance in coho salmon and Chinook salmon and 2) water temperatures to which fish were exposed during the experiment.
This data set documents the carbon and nitrogen stable isotope ratios of age-0 Arctic cisco (Coregonus autumnalis) captured in Prudhoe Bay, Alaska in August 2009. The analysis of this data was published in von Biela et al. 2013 (Polar Biology 36:137-146, doi:10.1007/s00300-012-1244-x). All stable isotope results were provided by the University of Alaska Anchorage Environmental and Natural Resources Institute (ENRI) Stable Isotope Laboratory. The Stable Isotope Facility was led by Dr. Jeffery Welker and managed by Brian Cohn at the time of the analysis.
