Shellcracker guys are much more secretive than crappie folks ever thought about being. Look in major coves that have sandy bottoms with creeks running into the main bay. Shellcrackers will be deeper than bluegills most of the time even though I have caught some good ones fishing buck bushes with crickets in very shallow water. Most of the time the shellcrackers will be where your boat would normally be when you are fishing a bluegill bed.

Hope that helps. That's all I'm telling. That's my story and I'm sticking to it!!
