You can't use live bait anywhere in Idaho. You just have to figure out something else.

Are you serious.? I have Nevah heard of such a thing. Here in NH...we have “Trout Ponds” that are off limits to ice fishing...that season is from the 4th Saturday in April - and closes Oct 15. Then we have Fly Fishing only ponds... But there are plenty of waters to catch trout through the ice. We can use smelt ,shiners ,tip up suckers with a single hook only. Dang smelt are almost a buck a piece....10.00 gets you a dozen.

Cook up some pot barley, drain , stir in some Dr juice liquid trout oil, while it is still hot. . . I use it for lake trout but would likely work for rainbows. Keep dropping a few bits down regularly. The white will attract them , as they sink, , as well as the oil in the water column. I use a minnow on bottom mostly but anywhere in the water column will work. You could try some on a small hook. You can keep it in the freezer between fishing trips. Take a plastic spoon to dip it out , it is oily.. Good luck old243
