Scuds don’t get nearly the credit they deserve. For an insect that makes up such a substantial portion of a fish’s diet over the course of a year, they are rarely talked about and more importantly, rarely fished.
The Pregnant Scud is surprisingly agile in the water but its unpredictable movements can make it challenging at times to fish correctly. Watch a few videos of scud behavior in the water and it will give you much better sense of the type of action you should give when drifting or retrieving a scud pattern.
