Genomics in Selective Breeding of Atlantic Salmon
Genomics is beginning to have an impact on Atlantic salmon breeding. For the past two decades, a large number of valuable tools have been delivered within the research community, including the recently completed genome sequence. A breakthrough for genomics in Atlantic salmon breeding came with the implementation of MAS for in increased resistance to Infectious Pancreatic Necrosis (IPN). In Norway, MAS for IPN-resistance has contributed strongly to a 75 % decline in the number of IPN-outbreaks since 2009. The putative functional mutations, underlying this QTL, has now been identified, and are being investigated using functional testing. With high-density SNP-chips now being available, breeding companies are also starting to implement genomic selection (GS), shown in simulation studies to have large potential in Atlantic salmon.
