J:son Scud 3 Olive Brown #14

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:

1. Cast your fly and let it sink to the desired depth.

2. Make a short, quick pull on the line to imitate the scud’s forward jump.

3. Let the fly fall slowly and naturally through the water column.

4. 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 Slim Profile Specialist – The J:son Scud 3 in Olive Brown is a highly effective imitation of a freshwater shrimp, measuring 12 mm in length. Tied on a size #14 hook, this pattern offers a slightly slimmer and more elongated profile compared to larger models, making it ideal for matching specific scud species found in both rivers and lakes. The olive-brown coloration is a fantastic all-rounder, mimicking scuds that live among darker gravel, mud, or submerged vegetation.

Despite its refined #14 hook size, we have engineered this fly with a generous hook eye that is easy to thread, ensuring you spend more time fishing and less time struggling with your leader. Featuring J:son’s signature anatomical segmentation and a realistic, semi-translucent body, this 12 mm scud is designed to come alive in the water. When fished with the "jump-and-fall" technique, it provides the exact visual cues and movement that trigger aggressive takes from hungry trout, grayling, and whitefish.
