Description: Abundance and age and length compositions of Arctic grayling Thymallus arcticus were estimated for a portion of the Chatanika River, sampled during June of 1995, using a modified Petersen estimator. The Chatanika River study area extended from 3.2 km above the Elliott Highway bridge downstream to 8.2 km below Any Creek, totaling 37.8 km. Estimated abundance of Arctic grayling > 150 mm fork length for the Chatanika River study area was 8,930 fish (SE = 779). Estimated density of Arctic grayling > 150 mm fork length within the Chatanika River study area was 236 fish per kilometer (SE = 21). The density of age-3 fish was 19 fish per kilometer (SE = 3) and the proportion of age-3 fish was 0.08 (SE = 0.01). The density of Arctic grayling > 270 mm fork length was 87 fish per kilometer (SE = 9) and the proportion of Arctic grayling > 270 mm fork length was 0.37 (SE = 0.02).
