Description
Few aquatic insects are as important to a fish's diet as scuds. These small crustaceans make up a huge portion of the biomass in still waters and slow-moving parts of rivers and streams all over the world, providing a constant, high-calorie meal for fish throughout the year. When fish seem to ignore all other flies, chances are they are keyed in on scuds.
To get the most out of your scud imitation, it is vital to mimic its unique, jerky swimming motion. A real scud propels itself forward by bending its body—almost into a circle—and then quickly straightening out. This creates a "jumping" movement through the water that is irresistible to trout and grayling.
How to fish the J:son Scud:
-
Cast your fly and let it sink to the desired depth.
-
Make a short, quick pull on the line to imitate the scud’s forward jump.
-
Let the fly fall slowly and naturally through the water column.
-
Repeat with brief pauses between each pull.
By imitating this specific behavior, you offer the fish a familiar and easy meal that often triggers a take when nothing else works.
The Delicate Protein-Bomb – The J:son Scud 2 in Light Olive is a meticulously detailed imitation of a medium-sized freshwater shrimp, measuring approximately 14 mm in length. Tied on a size #12 hook, it strikes the perfect balance between visibility and a delicate profile, making it a "must-have" for technical fishing in clear water or when fish are focused on smaller crustaceans.
Despite its compact size, we have designed this fly with a user-friendly hook eye that is easy to thread, even with standard tippet materials. Using J:son’s signature anatomical design, this scud features a perfectly curved, segmented body and a realistic translucency that mimics the natural shell of a live crustacean. Its light olive hue is especially effective in waters with abundant vegetation, providing the extreme realism needed to fool large, cautious trout and grayling year-round.
