Potential disease interaction reinforced: double‐virus‐infected escaped farmed Atlantic salmon, Salmo salar L., recaptured in a nearby river
Abstract The role of escaped farmed salmon in spreading infectious agents from aquaculture to wild salmonid populations is largely unknown. This is a case study of potential disease interaction between escaped farmed and wild fish populations. In summer 2012, significant numbers of farmed Atlantic s...
