The Dolly Varden, Salvelinus malma, is a salmonid fish found in cold-water streams and coastal waters of the North Pacific, from Korea to the Bering Sea and North America. Known for its vibrant coloration and aggressive nature, this species is popular among anglers. It can be anadromous, migrating between freshwater and the sea, or landlocked in lakes.
