Available in PDF, EPUB and Kindle. Book excerpt: Arctic grayling (Thymallus arcticus) stocks were assessed at Ugashik Narrows and Outlet in Southwest Alaska during the open-water periods of 1987, 1988, and 1989. Abundance, size, and age data were collected, which were then compared with historical data for 1968-1984. The Narrows is the stream between Upper Ugashik Lake and Lower Ugashik Lake, and the Outlet is the source of the Ugashik River from Lower Ugashik Lake.

This book was released on 2019 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gulkana River, located along the Richardson Highway near Glennallen, Alaska, supports the largest Arctic grayling (Thymallus arcticus) fishery in the Upper Copper Upper Susitna Management Area. Most of the fishing effort and harvest occurs in a 75 km section of the mainstem river between Paxson Lake and Sourdough Creek. From 1989 until present, the Arctic grayling daily bag limit downstream of Paxon Lake has been 5 fish, only one of which can be over 14 inches. To evaluate the effectiveness of this regulation, a stock assessment was performed for the Arctic grayling population inhabiting the 75 km section in July and August 2017. Mark-recapture techniques were used to estimate abundance and length composition of the population. Using hook and line gear, a total of 3,002 Arctic grayling ≥240 mm fork length (FL) were captured; however, too few fish were recaptured (m2 = 6) to estimate abundance without bias. Data collected during this study was compared to previous stock assessments, and it was concluded that the mainstem Gulkana River does not support substantial numbers of large Arctic grayling during the summer. Given the composition of the population (numerous Arctic grayling

Available in PDF, EPUB and Kindle. Book excerpt: This project plan outlines a two-event mark recapture experiment on Arctic grayling Thymallus arcticus in Beaver and Nome Creeks. Sampling will be conducted in 36 river kilometers (rkm) of the mostly road-accessible portion of Nome Creek and in the 44 rkm floatable portion of Nome Creek to the confluence of Beaver and Wickersham Creeks during July 2023. This follows a 2-year radiotelemetry study on Arctic grayling in the Beaver Creek drainage, where information acquired on life history such as migration timing, seasonal habitat preferences, and distribution has informed the timing, index area, and future data analyses for this mark-recapture experiment. The marking event will occur in early July, where three 2-person crews will sample a total of 6 rkm each day (i.e., 2 rkm per crew) and deploy approximately 1,000 Floy tags in Arctic grayling ≥250 mm FL. The recapture event will occur in late July, where Arctic grayling will be captured throughout the index area using the same methodologies employed during the first event and fish will be examined for tags. The population estimates acquired in 2023 will be compared to the last assessment conducted in 2000.
