I've only seen whole frozen smelts for sale in Alberta, where live bait is illegal. You may find someone who has them in their own freezer but it might not be an easy task.
Maybe with a well matched jig head and a trailer quick strike hook, the gutted smelt would work???
This spring, net some smelts and keep them in your freezer., smelt fishing is SOOOO much fun ..I've got some beauty chub I'm keeping for lakers and pike this winter.
