Jimk, I was concerned about my bluegill and bass also. I discovered I had bullheads in my pond and started catching the small fingerlings with a small mesh net. Twice I have caught bluegill and coppernose fingerlings hatched this year. I have also caught a good many freshwater shrimp to my surprise! While walking the banks to capture bullheads I have spotted several bass some have tripled in size. I would think that some of your bgill fry may have been meals to other species, but some if not many will survive.
