Lake Superior’s “Coaster”—or “Coastal”—trout is a variant of the more common brook trout that has adapted to conditions in the lake. While not a listed species, it is distinct from the brook trout in size and color. Coasters are beautiful, colorful fish that live at least some of their life in the Great Lakes. Named because their favorite habitat is Lake Superior’s rocky shore line, coasters were favorites among 19th Century anglers. Populations declined because of over-fishing, habitat loss, human activities such as logging and mining, and the introduction of non-native fish that compete with the trout for food, shelter, and habitat.
Challenges to Coaster restoration include habitat loss, poor watershed conditions, extirpated populations of the trout due to over-fishing, and an altered landscape.
