Description: The number of Arctic grayling Thymallus arcticus over 249 mm in FL was estimated at 4,975 fish (SE = 611) in a 17km section of the Niukluk River. Arctic grayling captured from the Niukluk River ranged in length from 172 mm to 501 mm FL and in age from 4 to 15 years. Arctic grayling aged 7 and 8 years comprised 55% of the estimated population, and fish from 400 to 450 mm FL comprised 62% of the estimated population. The estimated population in this section of the Niukluk River was approximately twice that estimated in 1990. In the Nome River, 670 young-of-the-year Arctic grayling were captured and moved to an experimental rearing pond as part of a restoration effort.
