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 Micro-Crustacean – The J:son Scud 3 in Light Olive is a precision imitation of a small freshwater shrimp, measuring approximately 12 mm in length. Tied on a size #14 hook, this is the ultimate choice for technical fishing when fish are feeding on smaller specimens or when the water is exceptionally clear. The light olive shade mimics the translucent, vibrant appearance of scuds living in weed beds and oxygen-rich environments.
Even in this compact size, we have maintained a user-friendly hook eye that makes it easy to thread your tippet during a hatch. Built with J:son’s hallmark anatomical realism, the fly features a segmented shell and a life-like silhouette that perfectly replicates the "jumping" motion of a real scud when retrieved with short, quick pulls. This 12 mm Light Olive Scud is a vital addition to your box for those days when the fish demand a smaller, more subtle presentation.
