Parasites of arctic charr Salvelinus alpinus (Linnaeus) and their use in separating sea‐run and non‐migrating charr
Metazoan parasites of arctic charr, Salvelinus alpinus , from the Nettilling Lake–Koukdjuak River system, Baffin Island, were studied. Non‐migrating charr hosted 9 species of parasites while sea‐run charr hosted 15 species of parasites. Diphyllobothrium spp., Eubothrium salvelini , and Proteocephalu...
