Title All trout sampled
Downloaded 6 times
Description File including the length, weight, and river sampled from for each fish in the study, as well as the unique identifier of each individual. Individuals can be traced through all other files through this identifier.

Title Kicksampled invertebrates
Downloaded 5 times
Description Number of invertebrates from each taxonomic group found in kicksamples taken in each stream. The number of invertebrates was estimated by counting a large subsample, then multiplying up to reach the number of inverts in the whole sample.

Title Quantitative Fishings
Downloaded 4 times
Description Quantitative fishing effort for all streams used in the study to calculate average density of fish in both groundwater and surface water fed streams. The file shows raw data for counts in each run, number of runs fished, and length and average width of the stream in the sampled section. Densities are calculated using a removal sampling formula to calculate "true" number of fish in the section, then dividing by the area.

Title Stomach contents
Downloaded 4 times
Description Raw stomach content count data. For every fish, with its given unique identifier number, the number of prey items of each taxonomic group found in the stomach is given. These are total counts of all stomach contents, not estimates based on a subsample.

Title Raw Isotope Data

Description Raw isotopic values for each fish, along with length, weight and unique identifier for these fish. In addition, baseline values for each stream are also contained in the file.

Title Habitat Data
