Abstract:1989 to 2002; 2005; 2010-2011 long-term tagging file for Arctic Grayling (Thymallus arcticus) on the Oksrukuyik. All grayling adults and juveniles captured during the field season are measured, weighed, tagged and released. Grayling were tagged with a colored tag with a number. . In 1993, researchers started pit tagging the grayling. These pit tags can be read with an antenna to track the migration of the grayling throughout the Kuparuk River system

Methods:Adult and juvenile grayling were tagged with floy tags during the summer seasons 1989-2002, 2005 and 2010-2011. Red floy tags were used for all fish caught in Oksrukuyik Creek. Total length, weight, and location caught were recorderd with each tagged fish. . In 1993, researchers started pit tagging the grayling. These pit tags can be read with an antenna to track the migration of the grayling throughout the Kuparuk River system.
