I don't icefish, but know plenty of guys that do.
Fish the creek channels, dropoffs or any available green weeds you can find.
If there is snow cover on the ice I don't think it matters weather it's night or day. It's still dark under the ice.
Use tip ups with small minnows at different depths. Once you find the depth of the fish set the rest the same.
If you prefer to jig do so slowly.
Hint: The regulars on our local lakes mainly fish the creek channels.
