Arctic Grayling in Alberta: The Sail-Finned Fish of Northern Rivers
Arctic grayling carry a large, colourful, sail-like dorsal fin and are among the prettiest fish you can catch in Alberta. They are a cold-water species of northern rivers, and a species that deserves careful handling.
How to identify an Arctic grayling
The dorsal fin is the giveaway: very large, colourful and rounded at the top, much larger than that of any other cold-water fish in Alberta. The body has large scales with brown or black spots behind the head.
Average length is 30 to 40 cm (12 to 16 in), with a maximum of 55 cm (22 in), and average weight is 300 to 800 g.
Where to find Arctic grayling in Alberta
In Alberta, grayling are found mainly in the Athabasca, Hay and Peace river drainage systems, and a small population lives in the Belly River in the southwest of the province. A small number of mountain ponds have been stocked.
They live mostly in streams and rivers and migrate from lakes and larger rivers into smaller streams to spawn in May and June.
Behaviour and feeding
Grayling eat a wide range of aquatic and terrestrial invertebrates, and fish eggs and small fish can supplement the diet. They rise readily to small dry flies, which makes them a special target for dry-fly anglers.
Spawning males are territorial. No nest is built, and eggs hatch 13 to 18 days after being deposited.
