I'm hardly an expert, and usually catch only one to six crappie an outing when icefishing. They are earlier posts on here pointing out that you can target crappie by lightly jigging fatheads just above the weedbeds. I usually icefish Hopatcong and had a great day years ago doing this in Henderson's Cove, but I'm sure it works over weed beds elsewhere. Generally you catch more sunfish on small jigs with mealworms/mousies in the weeds but occasionally you get into a crappie school. Some generalizations (most same as for open water): often bite well early and late, prefer slightly deeper water than sunnies and pickerel, and hang out at edges of weedbeds and other cover. Will often trip tipups, but I've had better luck catching on small shiners on tipups (better than fatheads for some reason; shinier?) Very often you'll catch several from the same hole (cover?) They are great eating, good luck!
