This dataset 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, Alaska, 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 dataset was used to validate and refine the use of gene transcription and HSP70 protein levels as heat stress biomarkers for Yukon River Chinook salmon.

This data release contains one table with heat shock protein 70 (HSP70) abundance measurements of Pacific salmon (Oncorhynchus spp.) muscle samples, collected from fish occupying freshwater in various Alaskan watersheds. Water temperatures associated with a sampled fish are also included in the dataset, when available. Gene transcription results from fish included in this data release are published in a separate data release; https://doi.org/10.5066/P19M3AYH.

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.

A genetic analyses of samples from the Chinook salmon (Oncorhynchus tshawytscha) bycatch from the 2007-2013 Bering Sea-Aleutian Island and Gulf of Alaska trawl fisheries for walleye pollock (Gadus chalcogrammus) were undertaken to determine the overall stock composition of the bycatch. Samples were genotyped for 43 single nucleotide polymorphism (SNP) DNA markers and results were estimated using the Alaska Department of Fish and Game (ADF&G) SNP baseline.

Genetic data of salmon bycatch samples collected by fisheries observers are used for mixed-stock analyses to determine geographic region of origin. This work is done at the Auk Bay Lab in Juneau Alaska. The data are loaded to the the North Pacific Halibut and Groundfish database maintained by FMA Division at the Alaska Fisheries Science Center in Seattle Washington

Tabular dataset containing age, sex, and length data for Chum, Chinook, and Sockeye salmon. Sex was determined externally using visual clues such as snout shape and size. Length was measured from fork to mid-eye with a measuring board to the closest 5 mm. Strata refers to the potion of the run the fish was sampled during. Strata data is based on the size of the population rather than date since the salmon run does not start on one specific date year by year. Scales were also taken and placed on a gum card for age assessment. One scale was taken for all sampled Chum salmon and three scales were taken for all sampled Chinook salmon.

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.
