Development and evaluation of SNP panels for the detection of hybridization between wild and escaped Atlantic salmon (Salmo salar) in the West Atlantic
Hybridization between wild and escaped cultured Atlantic salmon (Salmo salar) can threaten the stability and persistence of locally adapted wild populations. Here we describe the development and validation of a genomic-based approach to quantify recent hybridization between escapee and wild salmon i...

Hybridization between wild and escaped cultured Atlantic salmon (Salmo salar) can threaten the stability and persistence of locally adapted wild populations.
