Among the thirty-four natural and experimental secondary hosts found in scientific literature are the coastal cutthroat trout, rainbow trout, coho salmon, chum salmon, and kokanee salmon.
Wild fluctuations in sea-lice infestations on wild pinks and chum salmon between 2001 and 2005 gave way to a decade of low sea-lice levels, until last year.
Fish species inhabiting the river and its related lakes and streams include sheefish, burbot, whitefish, sucker, king and chum salmon, northern pike and arctic grayling.
