Coregonidae, commonly known as the whitefish family, includes various species of freshwater fish primarily found in the northern hemisphere. They are characterized by their elongated bodies, forked tails, and silvery scales. These fish inhabit cold lakes and rivers, often preferring deep, clear waters. Members of the Coregonidae family are important for both ecological balance and commercial fishing. They serve as a food source for larger predators and are sought after by anglers for their mild flavor. Notable species include the lake whitefish and Arctic cisco, which play significant roles in their respective ecosystems.
