Selection against individuals from genetic introgression of escaped farmed salmon in a natural population of Atlantic salmon ...
The viability of wild Atlantic salmon populations is threatened by genetic introgression from escaped farmed salmon. Farmed Atlantic salmon are genetically improved for important commercial traits and a life in captivity but are poorly adapted to the natural environment. The rate of geneflow from es...

The viability of wild Atlantic salmon populations is threatened by genetic introgression from escaped farmed salmon. Farmed Atlantic salmon are genetically improved for important commercial traits and a life in captivity but are poorly adapted to the natural environment. The rate of geneflow from escaped farmed to wild salmon depends on their spawning success and on offspring survival at various life-stages. We here investigate relative survival of introgressed juvenile Atlantic salmon (parr) in a river in northern Norway.
