Grayling are definitely unique fish and although not known to grow very large (17 inches is the largest on record in Colorado), they have an aura about them that entices many fishermen. They have a higher tolerance to lower oxygen levels which allows them to survive winters in harsh climates where other species cannot. If you're interested in catching one of these sail-finned fish, you're in luck because these fish are not known to be picky. Although they have small mouths which make them more difficult to catch with conventional tackle, they are often willing to attack dry flies on still water. <br />

Grayling have extremely small mouths and can usually only be caught on small flies or lures. Even though grayling are relatively small in stature (usually less then 12 inches), they can be a nice challenge to anglers, not to mention a great photo opportunity.
