Just wondering if anyone can tell me some good single hook artifiacial lures to use on trout in delayed harvest streams.Thanks ;D

Of course, spoons are classic trout lures. One that might not be at the forefront is grubs on jigheads, which do indeed catch fish.

(Most spoons come with a treble, but that can be swapped for a single hook.)

Try Rooster Tails or some other type of small spinners.
