Genetic resistance to SAV2 virus

Offentlig prosjektsammendrag

Pancreas disease is a major disease causing significant morbidity and mortality in Norway. There are a number of viral variants causing this disease the most common in Norway being the SAV3 variant. MarineHarvest Norway has already been selecting for resistance against this variant with some success for a number of years. Another variant called SAV2 is becoming an increasing problem and underlying cause of PD outbreaks in MH south and mid in particular. This project will investigate the genetic variation in response to an infection of the SAV2 virus among family identified fish and will compare the genetic response to that from the SAV3 virus to investigate whether the same genes are involved.
