Risk map and spatial determinants of pancreas disease in the marine phase of Norwegian Atlantic salmon farming sites
Background: Outbreaks of pancreas disease (PD) greatly contribute to economic losses due to high mortality, control measures, interrupted production cycles, reduced feed conversion and flesh quality in the aquaculture industries in European salmon-producing countries. The overall objective of this s...
