dbw you might add the size of your pond and the numbers and types you stocked, if available.
My similar experience has been that the predator will eat any fish it can catch large or small, whatever is available. Mines' catchability has been the same, difficult. Which leaves me with the same forage base you describe, only parents or babies.
I have raised a small number of fish to use as live bait and will try to use them to determine the size of my predators. If stunted I will remove them.
