Graylings
[Genus Thymallus]

These fish belong to the Salmon family along with Trout and Whitefish. They inhabit fresh waters in the far north and are easy to tell from trout by their large scales and a very large and showy dorsal fin. The longest and most commercialized (wild and farmed) is the Arctic Grayling (T. arcticus arcticus) which may grow to 30 inches and over 8 pounds. The grayling proper (T. thymallus,) is a European species that may grow to 24 inches and weigh as much as 15 pounds.   Drawing of Arctic Grayling by U.S. Fish an Wildlife Service = public domain.
