Pond Boss Forums STOCKING A NEW POND Raising Forage and Bait Feeder Pond

I have a small 1/4 acre pond directly upstream from the main pond. The pond is about 3 foot deep and feeds directly into the lower pond from an 8 inch culvert. I am thinking that tilapia would be a good choice but I have know idea how you would transfer the fish to the lower pond. I am assumeing that heavy rains would not transfer many fish. Would converting the 8 inch drain into a siphon and running without a screen relocate any fish?
