shellcracker beds

Found some beds yesterday although it was just a small area maybe 15 total beds. Does anybody know for sure if shellcrackers will move in on the empty beds that were occupied by fish caught (now in my freezer) on this same moon phase? I have caught fish on the same beds on consecutive days but these were big areas with no way of knowing how many beds were really there.

I caught some off of beds in about 18 inches of water yesterday, and I actually saw a bed taken over within about 10 minutes of me pulling the original "homeowner".
