About the grayling

Grayling are a graceful, sail-finned relative of the trout that thrive in cold, clean, fast water. They keep feeding well into the cold months when trout have shut down, which makes them a favourite target for autumn and winter fly anglers. That huge dorsal fin makes a good one unmistakable.

Catching grayling

Grayling hold in shoals in steady runs of moderate depth, so once you find one, work the water around it carefully. They feed hard on the bottom, so a well-presented nymph is deadly, but they will rise to a small dry too. Their soft mouths mean a gentle hand on the strike.

Before you fish: closed seasons, minimum sizes and catch limits differ by country and by water, and they change. Always check the current local rules and buy any licence you need before you go.
