Infection of Salmincola edwardsii (Copepoda: Lernaeopodidae) in an age‐structured population of Arctic charr—a long‐term study
The parasite‐host relationships between Salmincola edwardsii (Copepoda: Lernaeopodidae) and Arctic charr Salvelinus alpinus were studied in lake Takvatn, northern Norway, over an 8‐year period. The infection levels were modest, with an overall prevalence of 16·1% and an abundance of 0·5 parasites fi...
