Sudden increases in stream flows during hatching and emergence of larval Arctic grayling may decrease survival and limit recruitment in the Big Hole River (Shepard and Oswald 1989). The author with a Park Lake Arctic grayling this spring. Retention of adaptive rheotactic behavior by F1 fluvial Arctic grayling. Brood populations are located at two Montana lakes and the Yellowstone River Trout Hatchery, in Big Timber, Montana.
Research has identified limiting factors, and management strategies have been developed to protect and enhance fluvial Arctic grayling and their habitat. Conversely, extreme low flows during severe drought decrease survival of older Arctic grayling due to high water temperatures, increased susceptibility to predation, and diminished habitat volume. Location: Arctic grayling are native to drainages of the Arctic Ocean, Hudson Bay and northern Pacific Ocean in North America and Asia. Currently, only Red Rock and Odell Creeks appear to support spawning by endemic adfluvial Arctic grayling (Boltz 2006).

In Montana, both life forms of Arctic grayling exist, lake dwelling (lacustrine or adfluvial) and river dwelling (fluvial). However, the abundance of brown trout in upstream sections of the Big Hole River (upstream from Mudd Creek Bridge) is increasing, potentially due to increased temperatures from drought conditions, habitat alteration, and climatic change. _____. Fast growth rates and a short life span result in domination of spawning by age 3 and 4 fish. Those who camp on popular Spencer’s Mountain behind the Triangle X Ranch are facing a two-mile hike to Toppings Lakes for fishing, but the fishing you’ll get is well worth the trip. Thus, poor spawning success in a given year may substantially affect recruitment to the population for years. “The commitment of landowners along the Big Hole River is commendable and absolutely essential for the survival of grayling. 1989).
