Abstract

Silver salmon (Oncorhynchus kisutch) infected with the metacercariae of the "salmon poisoning" fluke (Nanophyetus salmincola) remain infected after they have migrated to sea. Metacercariae remain viable in such salmon for at least 33½ months. These metacercariae are capable of transmitting salmon disease (Neorickettsiae helminthoeca) to susceptible dogs throughout this period.
