This member of the charr family was once classified as a separate species, with the scientific name Salvelinus oquassa. A landlocked, or nonanadromous, charr, it was reclassified as a subspecies of the arctic charr (S. alpinus oquassa), along with its close relatives the Sunapee trout and the Quebec red trout. The blueback trout of Rangeley Lakes, Maine, were once extremely abundant but are now extinct; however, bluebacks are abundant in a few other waters of this state, and there is open-water fishing for them.
