Wouldn't try
If it was a viable bait, you could be sure someone (Berkley, etc) would be selling them for it. It sure would be nice, to open a bag of shad baits instead of castnetting for them !
I've caught alot while trolling on crankbaits too. I bet if you were to use a natural bait, and fish it like an artificial, it would work. Worm/shad on a jig, worm harness, etc. You'd stand a good chance of moving it in front of a catfish that way, rather than waiting for the fish to find it.

I know the eye guys catch a few by accident that way.
Anyway, that's just my guess, seems like it would work. I've got them on spoons and jigs below dams on the Ohio and the GMR also.
