A common garden design reveals population‐specific variability in potential impacts of hybridization between populations of farmed and wild Atlantic salmon, Salmo salar L.
Released individuals can have negative impacts on native populations through various mechanisms, including competition, disease transfer and introduction of maladapted gene complexes. Previous studies indicate that the level of farmed Atlantic salmon introgression in native populations is population...
