I suppose it is also possible that when momma bird regurgitates its catch for chicks, fish, eggs, seeds, whatever, and some is missed there is another chance for stocking.
Who knows. Until recently, I didn't realize that tree frogs can tell that a pond had game fish in it and go somewhere else. First two years, tons of tree frogs. After stocking, I have not seen any even near it. I suppose they could be getting eaten, but I don't have bass.
