I'm confused as to why so many people think that GSF will find their way into your pond by themselves. They don't get there unless they can swim from point A to point B (your pond) or a human puts them there. They can't walk! I guess it is possible that hybrid bluegill could revert back in subsequent generations to pure GSF so that is a third option.
But I agree with all the other points about them being fun to catch and good to eat. But they also were not in your original plan. If you must remove them all you would have to drain and start over. I'm not sure you can ever be confident that by catching and trapping that they are all gone.
I disagree. Alot of ponds end up with fish that nobody stocked and had no other way of getting in.
