Gyrodactylus salarisinfecting allopatric Arctic charr Salvelinus alpinusfry: an experimental study of host survival
Artificially reared Arctic charr Salvelinus alpinus fry (post yolk‐sac stage) from Skibotnelva in northern Norway were exposed to infection with the monogenean ectoparasite Gyrodactylus salaris to determine if the parasite caused mortality in fry. About 95% of the fry became infected within the firs...
