Production of sterile salmon is an efficient measure to reduce genetic interactions between wild and farmed salmon. At present, triploidization is the only commercially available method to produce sterile salmon, and farming of triploid salmon is currently tested at so-called green concessions in the North of Norway.
The object for this project is to investigate whether there are differences in susceptibility between diploid and triploid salmon in regards to susceptibility to infectious disease of importance for the Norwegian aquaculture industry. We have chosen to focus on the bacterial skin diseases caused by Moritella Viscosa and Tenacibaculum sp, as these diseases especially cause problems in the cold waters of Northern Norway. In addition, we have included two widespread viral diseases, IPN and PD. Challenge trials with genetically identical diploid and triploid salmon will be performed within the projects with focus on pathogenesis and mortality. In addition, gene expression following infection will be compared, with specific focus on immune genes.
