Nymph
Scud
Also called Freshwater Shrimp
Short answer
The Scud is a nymph or wet fly that imitates freshwater scuds and shrimp. It is usually tied in sizes 12 to 18. Fish it year round on tailwaters and spring creeks. Especially good in winter, and immediately after a change in flow when scuds get dislodged.
Nymph Beginner #12-#18
Effective stillwater pattern. Fishes year-round, near bottom or around weed beds.

Scuds are small freshwater crustaceans that live in weed beds and gravel in cold, mineral-rich water. On tailwaters and spring creeks they exist in extraordinary densities, and trout in those systems eat them constantly and grow fat doing it. Where scuds are abundant, they are often the single largest component of a trout's diet.
The imitation is straightforward: a curved hook, a translucent dubbed body picked out for legs, and a shellback with a fine wire rib for segmentation. The curve matters — a scud at rest curls, and although a swimming scud actually straightens out, the curved silhouette has caught fish for decades and there is little reason to argue with it.
Color is worth paying attention to. Live scuds are usually olive, gray or tan; dead and dying ones turn distinctly orange or pink, and trout key on that. An orange scud after a sudden flow change or in the winter can be dramatically more effective than a natural color.
What does a Scud imitate?
Freshwater scuds and shrimp.
How do you fish a Scud?
Dead drift near the bottom, ideally along weed bed edges and drop-offs. Small twitches during the drift imitate the erratic swimming motion and often draw the take.
When should you fish a Scud?
Year round on tailwaters and spring creeks. Especially good in winter, and immediately after a change in flow when scuds get dislodged.
What are the quick tips for fishing it?
- Carry orange and pink as well as olive — dying scuds are a real trigger.
- Fish it tight to weed edges rather than in open water.
- Pick out the dubbing generously; the legs are what sells it.

Dressings vary by tier and region. Treat this as the common recipe, not the only one.
