Fish hatcheries are widely used to enhance fisheries and supplement declining wild populations. However, substantial evidence suggests that hatchery fish subject differential selection pressures compared their counterparts. Domestication selection, or adaptation the environment, poses a risk populations if traits specific success in environment have genetic component there is subsequent introgression between fish. Few studies investigated domestication on genomic level, even fewer done so parallel across multiple hatchery-wild population pairs. In this study, we low-coverage whole-genome sequencing investigate signals of three separate Chinook salmon,
