I believe the bullheads entered the pond while it was still under construction before the sides were built up. A heavy rain connected the nearby ditches to the pond and I believe thats how the BH and GSF were introduced. I dont see that ever happening again. So far the greenies havent been a problem. And I am able to remove young ones by trapping. But no such luck with the bullheads. But the pond is doing well, The BG and LMB are doing well. But I can only image how much better the pond would be without the unwanted fish. But because my BG are doing so well I am not willing to start over
If you have a LMB population they will eat BH. I have used dog food in traps to catch BH and have very good luck with that. But as everyone is saying you will have to do a complete start over to get rid of them. I don't think you have to, they add to the food chain for LMB and they will control them.
