Book Description
The management objective for the Nome River is to maintain an abundance of 2,000 Arctic grayling greater than 15 in TL (350 mm FL) in a 40 km index area. This project will estimate abundance and size composition of the Arctic grayling population present in this index area in 2021. Based on the results of this assessment, management of the fishery will be reevaluated as prescribed in the Nome River Arctic Grayling Management Plan.

Book Description
Sport fisheries season summaries and management recommendations for 2005 in the Northwest Management Area are presented. The Northwest Management Area consists of all waters north of the Yukon River drainage in Norton Sound, the Seward Peninsula, Kotzebue Sound, and the eastern Chukchi Sea to Point Hope. Sport and subsistence fisheries target chinook salmon, coho salmon, pink salmon, Dolly Varden, sheefish, and northern pike. Summaries of major sport, commercial and subsistence fisheries within the Northwest Management Area are detailed, including descriptions of recent performances, Alaska Board of Fisheries regulatory actions, social and biological issues, and descriptions of ongoing research and management activities.

Book Description
A stock assessment was performed for the Arctic grayling Thymallus arcticus population inhabiting a 25-km portion of the Niukluk River near Nome, Alaska. The study was conducted during June 2013 using a mark-recapture experiment to estimate abundance and length composition of the population. This population is periodically assessed to ensure that it is sustained at or above a management-prescribed level of 3,500 fish =350 mm FL, and this population was last assessed during 2005. Using hook-and-line gear, a total of 2,047 fish were captured. Estimated abundance of Arctic grayling =350 mm FL was 11,916 (SE = 2,139), of which 62% of the Arctic grayling population was 375-424 mm FL. No management actions were necessary because the abundance estimate exceeded the management objective and was sufficiently precise.

Book Description
A stock assessment was performed for the Arctic grayling (Thymallus arcticus) population inhabiting a 16.2 km portion of the Snake River near Nome, Alaska. The study was conducted during June 2016 and used mark–recapture techniques to estimate abundance and length composition of the population. This population is periodically assessed to ensure that it is sustained at or above a management-prescribed level of 600 fish ≥350 mm fork length (FL), and this population was last assessed during 2011. Using hook-and-line gear, a total of 255 fish were captured. Estimated abundance of Arctic grayling ≥350 mm FL was 764 (SE = 151), of which 85% of the population was 375–474 mm FL. No management actions were deemed necessary because the abundance estimate exceeded the management objective and was sufficiently precise.
