Abstract

Arctic grayling (Thymallus arcticus ) are presently absent from areas they formerly inhabited in Yellowstone National Park. A project has been begun to re-establish this species in areas of the Park within its former range. The purpose of this portion of the study was to examine the meristic characteristics of populations of Arctic grayling from Y.N.P. and Montana. The results of this work and those from the electrophoretic examination will provide information for the collection of stocks to be used for the restoration of Arctic grayling in areas of Y.N.P.
