June 30, 2026: Arctic Grayling in Interior Alaska, with Lisa Stuby Arctic grayling are one of the most beautiful freshwater fish in Alaska, with a large, sail-like dorsal fin and colorful markings. Discover how these remarkable fish survive the cold winters, brief summers, as well as the all-important spawning strategies that occur in early spring. During 2021-2023, a radiotelemetry study was conducted in Beaver Creek in the White Mountains National Recreation Area near Fairbanks to learn more about grayling seasonal movements and find spring spawning, summer feeding, and overwintering areas. The information gathered from this study can be applied to Arctic grayling in other systems, including the streams of Denali National Park and Preserve.
