Effects of the eye fluke Diplostomum spathaceum on the energetics and feeding of Arctic charr Salvelinus alpinus
In the present study, effects of the trematode eye fluke Diplostomum spathaceum infection and parasite‐induced cataract on energetic costs and feeding of hatchery‐bred one‐summer‐old Lake Saimaa Arctic charr Salvelinus alpinus were examined. The energetic effects (measured as oxygen uptake) of acute...
