Metazoan parasites of arctic char (Salvelinus alpinus L.) in a high arctic, landlocked lake in Canada

Abstract

Seven species of parasitic metazoans were found in 71 arctic char (Salvelinus alpinus L.) taken in Char Lake, Cornwallis Island, N.W.T., Canada (74°42′ N, 94°50′ W): Tetraonchus alaskensis (Monogenea); Diphyllobothrium sp. (plerocercoids), Eubothrium salvelini, Eubothrium sp., and Proteocephalus longicollis (Cestoidea); Cystidicola cristivomeri (Nematoda) and Salmincola edwardsii (Crustacea: Copepoda). Except for S. edwardsii these reports, from a population of S. alpinus which is confined to fresh water, constitute new northerly distribution records for North America. Reports of P. longicollis and C. cristivomeri from S. alpinus in Canada have not been published previously.
