Dave Parrish is correct.

Idaho regulations on pg. 50 state:


Artificial Lure: Any device made entirely of rubber, wood, metal, glass, feather, fiber, or plastic with hook or hooks attached. Bait of any kind may not be used with artificial lures when fishing artificial flies and lures-only waters.

Bait: Organic substances, other than rubber, wood feather, fiber, or plastic, attached to a hook to attract fish. Bait includes insects, insect larvae, worms, dead fish, fish parts, any other animal or vegetable matter, or scented synthetic materials.

My home state of Wisconsin fishing regulations state that:

"Artificial lure means a spoon, spinner, plug or other fish bait made of hair, feathers, cork, wood, rubber, metal, plastic or other synthetic materials, or combinations of these materials. An 'artificial lure' may not include natural or organic food stuffs such as corn, marshmallows, dough, cheese, meat, living or dead organisms or parts thereof, except hair, feathers, cork, wood and rubber."

Eel skin would be illegal under the Wisconsin regulations also.
