Panfish would be my target right now. Focus on areas where you found panfish late ice fishing and then start targeting shallower water. I will often use small plastics tipped with waxworms or small minnows for bait. As the water warms and begins to approach the 60 degree mark, crappies will move into the shallow water to spawn. I would also check some of the backwaters on Lake Wausau for perch. Take a kid fishing

See you on the water
