The Mountain Whitefish (Prosopium williamsoni) is a native freshwater fish found in cold rivers and lakes of western North America. It plays an important ecological role as both a bottom-feeder and a food source for larger predators. While generally stable, some populations face threats from habitat degradation, pollution, and changes in water flow. Conservation efforts focus on maintaining clean, cold-water habitats and promoting awareness of the species' ecological value to ensure its continued survival.
