Quantifying the diets of a non-native and native predator during juvenile salmon out-migrations in the Columbia River

This is the clean and raw data files needed to replicate the analysis for our paper. The data contains carbon and nitrogen stable isotope data from several species of fish collected in the upper John Day Reservoir in Washington State in 2012. The data contains stable isotope signatures from predatory Walleye and Northern Pikeminnow, as well as potential prey species. A spreadsheet with descriptions of the column names is included.
