How to Rig for Roach

Rutilus rutilus

Roach are one of the most widespread coarse fish in the UK and Ireland, found in rivers, canals, and lakes and often the first fish a young angler catches. Small hooks, fine line, and steady loose feed are the key, since they shoal up and compete for food once a swim is primed. Winter roach fishing on rivers can be excellent when the water carries a tinge of colour.

Float Rig

intermediateriver · lake

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.

  • Leader length18-24in from the float to the hook, shorten in clear water, lengthen in off-color water
  • Hooks#20 - #14 fine wire hook
  • WeightSmall shot bulked and spread to cock a stick float or waggler
  • Line to sinkerShot placed 8-12in above the hook, or spaced 2in apart in a cluster halfway down the leader for salmon

Feeder Rig
A small open-ended or cage feeder on a running link carries a load of groundbait or maggots out to the swim and empties on the bottom, while a longer, lighter hook length lets the bait fall naturally in that feed.
