The Arctic Grayling comes in a wide array of colors. Coloration can vary from stream to stream. Their dorsal fins are typically fringed in red and dotted with large iridescent red, aqua, or purple spots and markings. These colorful markings are most dramatic on large grayling.

MONTANA – The U.S. Fish and Wildlife Service announced its finding on August 20, 2014, that the Upper Missouri River Distinct Population Segment (DPS) of the Arctic grayling does not warrant protection under the Endangered Species Act (ESA). The Service reached this conclusion after analyzing the significant conservation efforts carried out by private landowners as well as federal and state agency partners to improve conditions for Arctic grayling in the Upper Missouri River basin. These efforts have helped bring the species to the point that it is not in danger of extinction now or in the foreseeable future, i.e., does not meet the definition of an endangered or threatened species under the ESA.
Private landowners in the Big Hole and Centennial valleys worked through a voluntary Candidate Conservation Agreement with Assurances (CCAA) to achieve significant conservation of grayling within its range. Since 2006, over 250 conservation projects have been implemented under the CCAA to conserve Arctic grayling and its habitat, including: riparian fencing, irrigation flow reductions, improved irrigation infrastructure, fish ladders, improved stock water systems, and both passive and active stream restoration. Habitat quality has improved and grayling populations have more than doubled since the CCAA began in 2006.
