Analysis of farmed fish movements between catchments identifies a simple compartmentalised management strategy for bacterial kidney disease in Scottish aquaculture

► Live fish movements have been identified as a risk in the spread of BKD. ► We analyse movements of live fish between the salmon and trout industries. ► Low cross compartment movements support a compartmentalised management strategy. ► Principles developed have provided advice to policy makers. ► A new disease control strategy for BKD has been implemented.
