Verdict
Can one setup do both?
Line ranges don't overlap
Rainbow Trout typically needs 4–8 lb line and atlantic salmon 15–25 lb. The gap is big enough that separate outfits are the sensible choice.
Shared methods
Techniques that work for both
Fly Fishing
Casting a weighted line that carries a nearly weightless artificial fly to the fish.
Spinning with Lures
Casting and retrieving spinners, spoons or small soft plastics on light spinning tackle.
