Thymallus thymallus

Current British record: 4lb 4oz (2009) Paul Mildred, Wessex River


This fairly flat sided fish is a relative to the salmon family, it has a smaller head in comparison to its body but is known for its beautiful large dorsal fin. The grayling is also known as ‘The lady of the stream’ maybe because of their flowing appearance beneath the water. Grayling are favoured by trout anglers as they make a good challenge and can be caught using similar tactics.
