Functional Genomics of Key Biological Traits in Atlantic Salmon

This lecture explores how functional genomics and live experimental models can be used to understand key biological traits in Atlantic salmon, with a particular focus on smoltification, disease resistance, and reproduction. By combining genomic approaches with controlled studies in live fish, we can investigate how specific genes and molecular pathways influence complex phenotypes and important life-history processes. These approaches provide valuable insights into the biological mechanisms underlying variation in performance, health, and reproductive traits. Ultimately, a better understanding of gene function and genotype–phenotype relationships can contribute to more sustainable aquaculture, improved fish health and welfare, and the development of more precise and informed breeding strategies.
