    Found in lakes, small streams, and big rivers. Peak fishing for arctic grayling is June through August. Most grayling average inches and about 1 lb, but fish up to 24 inches and 5 lbs have been recorded. During the brief summer, Arctic grayling are voracious feeders. In the present study, we conducted a mark-recapture survey to generate data on distribution and abundance of Arctic grayling within a km reach of the Wapiti River that should aid in formulating management guidelines for this species in Wapiti River system. A total of Arctic grayling were captured over the km stretch during our study.

    Arctic grayling grow to a maximum recorded length of 76 cm (30 in) and a maximum recorded weight of kg ( lb). Of typical thymalline appearance, the Arctic grayling is distinguished from the similar grayling (T. thymallus) by the absence of dorsal and anal spines and by the presence of a larger number of soft rays in these fins.

With its sail-like dorsal fin, iridescent marking and dotted with spectacular patterns, the Arctic Grayling is one of the most unusual and beautiful fish of Alaska.

Adult Arctic grayling spawn in mountain streams that have a strong current in shallow water with a rock and gravel bottom. DIET: Young grayling feed on zooplankton, with a gradual shift to immature insects as the grow.

You can find Arctic grayling of different sizes and ages throughout a whole river system. However, there is a discernable pattern of grayling sizes from a river’s headwaters to its mouth. The older, larger adults tend to lay claim to the cooler upper reaches of river.

The best grayling fishing is in the upper river, accessible from the Steese Highway. The Chatanika's tributaries, Tatalina Creek, Washington, Goldstream and Beaver creeks, are also good for grayling.

Arctic Grayling Thymallus arcticus were once the dominant salmonid in the Big Manistee River, Michigan, but were extirpated from the watershed around and from the state of Michigan bylikely due to overfishing, biotic interactions with introduced fish species, and habitat loss occurring largely around the turn of the 20th century.

Alaska Department of Fish and Game research on Arctic grayling focuses on collecting data for grayling population management. Management biologists rely on stock assessment data (how many and what size grayling there are in a lake or stretch of river).

They also need to know how many Arctic grayling are caught in a given season.The Denali Highway is located in the Alaska Fish & game regulations summary Susitna River Drainages area with exceptions. The Cantwell end of the Denali Highway and the Tangle Lakes areas are located within the Tanana River Drainages.
