Summary The project consists of three work packages that will provide knowledge about the effects of SAV infection and possible interactions between SAV and PRV.
Work package 1: Physiological effects of PD on digestion in salmon.
In this work package, we want to investigate how the loss of exocrine pancreatic tissue observed in PD affects the salmon's ability to absorb nutrients. No results have been published showing the direct effect of the disease on digestion during and after an outbreak, and it is unclear how large a proportion of the pancreas must regenerate before the salmon's digestion is normalized. The work package will provide a better understanding of disease development and effects on feed utilization, as well as form the knowledge base necessary to establish disease-reducing and cost-effective feeding regimes in connection with PD.
Work package 2: Pathophysiological effects of feeding regimen during outbreaks of PD in salmon.
It has been shown experimentally that a fatty acid composition with more omega-3 in the feed can modulate the immune response in fish and lead to less pathological changes, lower viral load and lower mortality from PRV infections in salmon. Whether this can be transferred to practical feeding regimes in commercial production is unclear.
It is necessary to establish experimental models that reflect normal operation in order to be able to document how different feeding strategies affect the fish's digestion after a PD course. This enables a cost-benefit analysis of the various feed and feeding strategies.
A.1.3 Work package 3: Co-infection with SAV and PRV.
A working hypothesis is that PRV infection can have secondary effects on the blood cells' immune response and affect the defense against other infections. To support or disprove this hypothesis, we will examine the interaction between SAV and PRV infection. In the first instance, we will investigate whether PRV infection can affect the outcome of a secondary infection with SAV2 or SAV3.
