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.

Pages : 44
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.
