I don't know your goals, but In my opinion stocking male and female BG together in an otherwise empty pond will certainly produce a bumper crop of yoy fish....enough that I can't imagine having to worry about the losses from predation caused by the larger BG.
I can see where boosting feed levels might satiate the larger BG, thereby slowing down consumption of yoy fish, but I also believe that a diet of high protein feed might ramp up the reproduction of your larger fish, resulting in even more yoy fish?
