Gyrodactylus salaris 2011

In 2011, Gyrodactylus salaris reappered in one salmon river. No Atlantic salmon or rainbow trout farms were found infected.

During the period of 1975 to 2010 pathogenic strains of Gyrodactylus salaris have been detected on Atlantic salmon (Salmo salar) fingerlings/parr in 48 rivers, 13 hatcheries/farms with Atlantic salmon parr/smolts and 26 hatcheries/farms with rainbow trout (Oncorhynchus mykiss). In addition, a non-pathogenic strain of G. salaris has been found on Artic charr (Salvelinus alpinus) in several lakes.
