The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
Arctic grayling have adapted to the rigors of the climatic and physical environment of the arctic. For almost nine months of the year, grayling are confined to relatively small reaches of stream and river channels for overwintering. The available overwintering habitat is critical to their survival and is considered to be the major limiting factor for populations of arctic fishes. After break-up, which begins in late May or early June, Arctic grayling expand their distribution to include streams and rivers that were previously frozen. Glacial rivers are used as migration corridors to tundra streams where grayling spawn and rear. The fish appear to return and spawn in the same stream in which they were born. Young of the year fish emerge from the gravel in late June and early July. In August and September, Arctic grayling return to overwintering areas in river channels associated with year round springs and deep pools. Grayling mature between the age of six and nine years.
