This is a collated dataset of various potential covariates that could influence salmon body size investigated for Oke et al. "Recent declines in salmon body size impact ecosystems and fisheries". The authors of this dataset were not the original collectors of these data, but instead collated them from publicly available datasets and published papers and reports. They are archived here for repeatability. We are very grateful to the people who originally collected these data.
