I just built a 1/2 acre pond in southern MN. It is about 6' at its deepest point. Average is about 4' right now. I have notice some swimming bugs that dive down very quickly and seem to float back to the surface. They are average .25" long with paddeling legs from the sides. Lots of them. I don't have any fish stocked yet. I'm looking to add some Hyb sunfish this week. They should be 3-5" long when I get them. Will these little bugs be a good enough food source or do I need to supplement food until the pond habbitat takes off?
