Yep it works....can be real good. Don't know where you get your gills from, but if it is near some weeds on a shallow flat or along a drop those weeds will start to grow and produce oxygen again if they are now getting sun light. The gills will move in there, but it is not right away. It will take some time. I would say if you have an area where you caught them in or near the weeds at first ice, there will be gills there again soon after ice out. Just remember to fish with small ice jigs, light line and also smaller bobbers if you are casting to them vs. vertical jigging.
