We will use this method to characterise juvenile Atlantic salmon in wild populations that experience different intrusion rates of farm escaped salmon. We will also compare populations of Atlantic salmon that are reared for conservation purposes in the Live Gene Bank for salmon with their wild population of origin. Our objective is to test if wild Atlantic salmon are affected morphologically by escapes. Morphological classification of individuals will be checked with a genetically-based assignment test using single nucleotide polymorphisms. We want to use these methods: 1.Morphological characters - a pronounced morphological variability has been shown to exist between wild and farmed populations. This variability may have energetic consequences for the salmon and these differences in morphology can yield a more optimal farmed salmon. We intend to determine morphological variation in a wide variety of different populations and strains. 2.Genetic variation -analyses of Single Nucleotide Polymorphism markers (SNPs) will be used to examine concordance between morphological classification of juvenile salmon and genetic assignment to wild or farm origin. Finally, the morphology and genetics data will be synthesized in an analysis to assess the degree of genetic interaction between farmed and wild salmon in rivers having different levels of i ntrusions of farmed salmon
Goal:
To determine variability in morphology and genetics among wild salmon and between wild and farmed populations of Atlantic salmon in order to determine the introgression of farmed salmon properties and genes in wild populations over the last 30 years. Variability in morphology and causes for its variation, will be determined and compared in farmed, gene-bank kept, and wild Atlantic salmon from Norway, Scotland and Canada.
Genetic variation will be determined for the same groups. The genetic effect of escaped farmed salmon, reproducing with wild salmon in nature, will be determined in analyzes of genetic and morphological change of selected populations over the last 30 years, where gene bank material represents the pre-escapement situation in Norway.
