Smelt are great eating. Just cut the heads off, open them and clean 'em out - then bread them up and throw 'em in the deep fryer and eat like french fries. Bones aren't an issue are they are so small. My 2 year old son even loved eating them. I was out a couple of nights ago and was able to see about a dozen swimming past the hole (just under the surface of the ice). Not able to hook any of them, so will give it a try again tonight. Most would just nudge the bait and keep on swimming, so I guess I will have to get creative and try a few different setups to try and hook 'em.
