Kuskokwim Bay chum salmon (Oncorhynchus keta) energy density, distribution, and stomach data, 2004 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.).

In one table, we provide the presence of fish species and the total species count for each lake or pond sampled. This table also includes metrics of surface water connectivity to the stream network. In a second table, stomach content information is provided for fish collected during summer sampling periods (late June to mid-August) over three years (2011–2013). The third table includes stable carbon isotope and stable nitrogen isotope signature data for fish species and snails (the baseline organism) from 16 water bodies at one study location...

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. Categories: Data Arctic cisco stable isotope data, Prudhoe Bay, August 2009 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. Categories: Data
