Two new studies have been published investigating hybridization between wild and escaped Atlantic salmon. First, Wringe et al. (2018a) demonstrates high accuracy and efficiency of a panel of 95 SNPs established to detect hybridization and introgression in the west Atlantic.

Following this development, Wringe et al. (2018b) applied the panel to Atlantic salmon populations in southern Newfoundland, showing extensive hybridization occurring throughout the region following a large escape event.
