On Lake Champlain we fish for them in winter through the ice by live bait (smelt , shiner or minnow) under a tipup, or jig them by rod and reel with a swedish pimple or maribou jig tipped with a minnow tail near bottom. In spring they are on top and we troll for them and use any minnow type lure like rebel or rapala. Summer we get them with the aid of a down rigger using flashers and spoons or minnow lures. I like nils master lures in blue or chartreuse.
