First glimpse into parasites of Arctic anadromous lake trout
Partial anadromy, where some individuals remain in freshwater while others migrate to sea, is common at northern latitudes. These life history differences can have ecological consequences impacting the parasite infracommunity, as parasite exposure varies

Bull Trout (Salvelinus confluentus) occur in many major watersheds in northwestern North America and are identified as “Threatened” or a “Species of Special Concern” in both Canada and the United States. Non-native fishes, including Brook Trout (Salvelinus fontinalis), are one assumed major contributor to declines of Bull Trout populations.
