Thanks for the responses guys. I am a ways off from stocking predators as we are still completing the purchase of our property and then I plan to renovate the existing puddle (currently 1/10th acre or so). In the mean time, I was debating using it as a grow out pond to raise some larger F-1s and stocking them in my dads older pond only a few miles from here. I don't know that I will try it, but was curious if anyone else had. Thanks again for the replies.
