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.
