Alpine bullhead (Cottus poecilopus Heckel, 1837): a potential refuge for Gyrodactlus salaris Malmberg, 1957 (Monogenea)
The notifiable freshwater pathogen Gyrodactylus salaris Malmberg, 1957 tends to be a generalist in contrast to other monogeneans. Whilst it causes most damage to its primary host, the Atlantic salmon (Salmo salar Linnaeus), transport and reservoir hosts likely play a key role in maintaining the para...
