How to Rig for European Flounder

Platichthys flesus

Flounder are the only UK flatfish that regularly runs up estuaries into brackish and even fresh water, following the tide to feed on crabs and worms in muddy creeks and channels. Peeler crab is the standout bait, and slowly twitching the bait along the bottom draws them in. Autumn and early winter, before they head offshore to spawn, is peak time.
