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 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.

Region(s) of distribution of Sockeye Salmon (Oncorhynchus nerka) (Walbaum, 1792) in the Arctic as digitized for U.S. Geological Survey Scientific Investigations Report 2016-5038. For details on the project and purpose, see the report at https://doi.org/10.3133/sir20165038. Complete metadata for the collection of species datasets is in the metadata document "Dataset_for_Alaska_Marine_Fish_Ecology_Catalog.xml" at https://doi.org/10.5066/F7M61HD7. Source(s) for this digitized data layer are listed in the metadata Process Steps section. Note that the original source may show an extended area; some datasets were limited to the published map boundary. Distributions of marine fishes are shown in adjacent Arctic seas where reliable data are available. The data were clipped to show only the marine distribution areas although some species also may have an inland presence.

A time series of scale samples (1956 2002) collected from adult sockeye salmon returning to Naknek River were retrieved from the Alaska Department of Fish and Game. These scales were digitized, revealing growth information for the freshwater and marine life history stages of sockeye salmon. The growth information will be related to time series of sockeye salmon production to Bristol Bay and oceanographic conditions within the Bering Sea and North Pacific Ocean.

A 2007 pilot study was initiated by the University of Alaska – Southeast in which baseline levels of contaminants, including persistent organic pollutants (POPs) and total mercury, were determined in whole bodies of juvenile coho salmon collected in streams in and near national park units in the Southeast Alaska Inventory and Monitoring Network. Although the concentrations of POPs determined in the juvenile coho were relatively low (< 10 ng/g, wet weight), the preliminary findings of this study indicate that, in the Glacier National Park region, salmon from streams with higher density of spawners had increased levels of certain banned chlorinated pesticides (i.e., alpha-chlordane, o,p’-DDT, p,p’-DDD) compared to salmon collected in other streams with lower salmon spawning density. A follow up study will be initiated in spring/summer 2015 to determine concentrations of POPs in resident salmonids, as well as benthic macroinvertebrates collected from five streams that have fish barriers near or adjacent to Glacier National Park. Comparisons in contaminant concentrations and patterns will be made for fish collected below and above the barrier in each stream to help determine if certain classes of POPs are being transported by the spawners. As part of this study, the NWFSC will analyze whole bodies/muscle of salmonids and benthic macroinvertebrate samples POPs using gas chromatography / mass spectrometry (GC/MS). Percent lipid content of samples (with adequate sample mass) will also be determined. These data will be included in a report to the NIH-sponsored IDeA Network of Biomedical Research Excellence. Determining levels of persistent organic pollutants in salmonids and macroinvertebrates.

This dataset contains environmental DNA (eDNA) concentrations and spawning adult abundances for sockeye salmon (Oncorhynchus nerka) in Hansen Creek, a small tributary in the Wood River watershed, southeast Alaska, USA. We took temporally- and spatially-replicated eDNA samples during the spawning period (mid-July through August), along with fish counts (live, naturally dead, and killed), dissolved oxygen (DO), discharge, and temperature data at each time of sampling. Samples were collected at each site before adults entered the stream, and then continued to be collected daily or every other day for the next three weeks.

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.
