In QuantEscape2 we shift emphasis from quantifying introgression to studying the ecological consequences of introgression. A novel method for estimating the expected proportion of farmed genome in individual fish provides us with unique opportunities to study the full variation of phenotypes in the wild, as a function of introgression. Cohort analyses of age-classified fish provide opportunities for estimating selection against farmed and hybrid genotypes. In a large set of controlled experiments using pedigreed material of farmed, hybrid, backcrossed and naturalised farmed salmon, we provide detailed study of the performance (growth, survival, smoltification and maturation) of individuals with known introgression level. Detailed genomic studies of the breeding lines in QuantEscape unraveled several loci that had been amplified in farmed strains, and we can now study the direct effects of these genetic changes in wild settings. Population-dynamic models will be used to predict future changes where experimentation falls short, and to analyse the interactions between introgression of farmed genes and other anthropogenic disturbances. QuantEscape2 will contribute to the sustainable management of farmed and wild Atlantic salmon, and benefit the aquaculture industry and wild salmon fisheries by providing guidelines for sustainable aquaculture.
