Sentinels in the bay: using farm fish to monitor for pathogens in the environment
Farmed Atlantic salmon were used in British Columbia as sentinels to determine whether fallowing farms and previously infected channels would effectively eliminate infectious haematopoietic necrosis (IHN) virus from a region. The sentinel approach involved re-introducing salmon to a few strategicall...

Farmed Atlantic salmon were used in British Columbia as sentinels to determine whether fallowing farms and previously infected channels would effectively eliminate infectious haematopoietic necrosis (IHN) virus from a region. The sentinel approach involved re-introducing salmon to a few strategically placed (sentinel) sites and subsequent monitoring for the presence of IHN virus over a specified period of time. Seven farmed Atlantic salmon sites with a history of infection were monitored for the presence of the virus for six months following a minimum fallow period of two months.
