This fish is characterized by its slender body, silvery scales, and a forked tail, typically growing up to 18 inches in length. Lake whitefish are an important part of the ecosystem and are often sought after for recreational fishing. They feed on small invertebrates and plankton, playing a crucial role in the food web. Their populations are monitored to ensure sustainable fishing practices and environmental health in their habitats.
