Research has been done on Atlantic salmon using MAS. The trait of greatest priority and interest for the salmon was growth, for economic reasons.  Many genes that have been linked to growth have been found and recorded, with more studies being done on these genes as time goes on. The studies were based on five genes, known as “…growth hormone (GH), insulin-like growth factor-1 (IGF-1), myostatin (MSTN-1), prolactin (PRL), and somatolactin (SL) genes,” (Ramos).

Another area of interest for MAS was for salmon and Infectious Pancreatic Necrosis. IPN is a disease found in salmon during their early stages of life, and usually kills the salmon before it reaches adulthood. This is seen as a huge problem for both the welfare and economy of aquaculture sectors, so scientists have turned to MAS to detect and breed salmon without the disease. The families of salmon with high resistance to IPN were tracked and selected for MAS, with the results in progress. (Citation 43)
