Analyte concentrations and stable isotopes in fish tissue collected across the upper Colorado River Basin in 2016 and 2017
These data were compiled to examine analyte concentrations, including mercury and selenium, and stable isotopes in native and non-native fish across rivers in the Upper Colorado River Basin. Data were collected in 2016 and 2017. Tissue samples were collected as whole-body or muscle plugs (biopsies). Tissue samples were analyzed for stable isotopes in 772 samples, for selenium and 54 other analytes in 646 samples, for total mercury in 379 samples, and for methylmercury in 337 samples. The data tables contain raw concentration data, as well as standardized conversions for differences based on tissue type (whole-body or muscle) and dry or wet weight.
