Coregonids

Coregonids are a diverse group of freshwater and anadromous fish belonging to the subfamily Coregoninae within the family Salmonidae. This subfamily includes whitefishes and ciscoes. They are characterized by their silvery bodies, often with adipose fins, and typically have large scales. Coregonids are found primarily in the temperate and Arctic waters of the Northern Hemisphere, with major centers of diversity in North America and Eurasia. They inhabit lakes, rivers, and coastal waters. Many species are commercially important, providing valuable food resources. Their diets vary but often include plankton, insects, and smaller invertebrates. Reproduction usually involves spawning in rivers or lakes, and some species undertake significant migrations. The taxonomy of coregonids is complex, with numerous species and subspecies, and ongoing research continues to refine our understanding of their evolutionary relationships. Factors such as glaciation have played a significant role in their distribution and speciation.
