D and I were looking at our pond and trying to decide how best to cull the herd. Not babies but some of the smaller sized babies that grew into 3-6" non-descript fish. Our pond is not very big and with the one koi becoming Moby Dick and the others that have been in the pond for several years we need to be careful. Wintering over is a very touchy process and too many fish could tilt the number of survivors drastically. We made one foray at it and that was very unsuccessful. We hope that as fall progresses, well starts, they will slow down a bit. Unfortunately as we start shutting down the pond and removing the plants they all dive for the cave at the bottom and we don't see them til spring - at least the survivors. It appears that all 25 survived last winter. But I see one baby from either early spring this year or unnoticed (it is black) from last year. Maybe 2" long. And one or two babies from this year. I think the fish have done a good job lunching on the eggs to keep the newer population down. Since we got the algae under control they really depend on my feeding them also
