The Fyggi is a Gammarus or Shrimp imitation. The most important seatrout food year around. The designer, Claus Eriksen likes to fish the Fyggi high in the water on a long 3x fluorocarbon leader. It is an especially good sea trout fly on quiet days where sea trout are sitting near the surface. A great sea trout pattern added by Claus Eriksen.
