Summary Pancreas disease (PD) is one of the major causes for losses during the seawater phase in the Norwegian salmon farming industry. PD is a viral disease caused by the salmonid alpavirus (SAV), and the infection causes loss of pancreatic tissue and damages the heart and muscle. This results in problems with nutrient digestion and poor feed utilisation, and further to reduced slaughter quality, poor growth and increased mortality, and represents an important welfare challenge for the industry. The present project aims to investigate whether nutritional status at the time of infection plays a role for how the fish handles the infection and how long it takes before the fish recovers, regains appetite and growth. The first part of this work will be to develop good tools (clinical, molecular and nutritional markers) to evaluate the role of nutritional status for tissue damage during an infection and how long it takes before the tissues are repaired (regenerated). Model systems (cell cultures) will be used to investigate mechanisms involved in the immune response to viral diseases, and whether single nutrients can influence the response. The established markers will be used to investigate whether the use of plant oils in the feed affects disease progression in large Atlantic salmon. The composition of salmon feeds has changed to include more plant raw materials over the past decades, resulting in a changed content of saturated, unsaturated, omega-3 and omega-6 fatty acids, which may influence the immune response and inflammation processes. Triploid salmon is being considered for commercial farming, and the present project will investigate how triploid salmon handles PD. The results from the present project will increase the knowledge on how nutrients influence fish health and disease susceptibility, and will be useful to reduce production losses and increase welfare in commercial salmon farming.
