How to Rig for Grayling

Thymallus thymallus

Grayling live in clean, fast-flowing rivers with gravel beds, and are recognised by their huge sail-like dorsal fin. They shoal up in winter and feed well in cold, clear water, which makes trotting maggots under a float a classic winter method once trout season closes. Handle them gently and quickly, since they are more delicate than trout.

Float Rig

intermediateriver

A float suspends bait at a fixed depth instead of dragging it on the bottom, letting current or light wave action carry it naturally past holding fish. This is the standard technique for salmon and steelhead in rivers, fished with roe or beads under a pencil float, and for light-tackle pier species like jacksmelt, where a small float and a multi-hook leader with tiny bait covers a school as it drifts through. Use it whenever fish are holding off bottom rather than on it, or when you want a natural drift through a current seam without snagging.
