Shrimp/Scud

Year-round Gammarus staple
Trout · GraylingSubsurface

Curved weighted scud imitation of the Gammarus shrimp — a year-round subsurface staple in weedy alkaline water.

Fish this when

Any month on weedy alkaline rivers and stillwaters, worked slow and low through beds of ranunculus or elodea where naturals live in numbers.

Why it works

The curved shank and translucent dubbing reproduce the scud's hunched swimming posture, a shape trout key on because it's present and vulnerable in the weed all year, hatch or no hatch.
