I think larger YP hit the small ones pretty hard. I have a lot of YP feeding on pellets right now but I haven't seen any small enough to be from last year's spawn. I still have a lot of small FHM and will stock more this spring. Visibility im my pond is always low, 8" or less, and I rarely see large FHM even after they are stocked. I catch a few large FHM in the minnow trap but I only remember ever catching 2 or 3 YP in the trap.
