Expect the panfish to prey heavily on the newly hatched crayfish. Abundant shallow cover is imperative for YOY crayfish survival. If you don't see evidence of crayfish spawn in mid summer you obviously did not stock enough or habitat for them was inadequate. If you want a crayfish spawn this year you will have to get them Mar-April. In my experience most papershells are done carrying eggs in NW Ohio by sometime in early to mid-May. Locations further south will have an earlier spawn cycle. I would buy more crayfish than you need. The current bass and larger YP will 'target' your stocker crayfish.
