Last night I caught eight crappies on jigs and mousies, while a tip-up with a minnow was set up not four feet away. The minnow produced not fish. I grabbed the tip-up and traded holes. Then pulled two crappie from the hole that the minnow was sitting in. Again the minnow produced no fish. The moral of the story is; its not your bait its your location. I'm not saying minnows don't work. The reason I had them is because I was crappie fishing and often they will out produce spikes and mousies. The info above is good. Crappies use "confined open water". Look for 'U' shapes in bottom contour, inside turns, points, road beds, channels, weed edges and the like. Good rule of thumb is "bait out crappies in". find a decent sized bay with relatively deep water (see 5-10 feet if the max depth in the lake is 20-30). If there is a decent sized flat with structure on the main lake side of the mouth of the bay the slabs will be there picking off the bait fish as theexit the bay. Another thing not metioned above is in a lake or pond void of structure mid winter crappies will be suspended over the deepest water, usually half way down. Always drop your bait slowly and in a manner where you can feel not only a tug, but weightlessness. They will hit up!! If you use a bobber use one you can balance so it will tip over if the bait is lifted, same with a spring bobber if it goes straight set the hook. Good luck.
