Out of the 1500 BG stocked I have caught around 50 hybrids that slipped in with the BG.
I have seen no ill effects and I enjoy catching them. I would not worry about it.
If they cross back with a few BG likely would have hybrids with lessening GSF characteristics.
That doesn't seem to be working out for me. I had a few, how many I don't know, got in with some bluegill. They grew great and were fun to catch but they crossed with bluegill like crazy. I've been running 2 minnow traps daily and if I catch 30 small fish, 20 of them have have strong GSF characteristics. I've been culling them and removing every one I catch while fishing also. The larger ones go to the table and those too small to eat get tossed. There's nothing wrong with the crosses but I just prefer straight bluegill. I know I'm fighting a losing battle but I guess it makes me feel better to try.
