Moonshaddows, that is pretty darn awesome! We have 60 acres and would LOVE to do something similar! I like the idea of a back yard pond. Fish should be pretty self sufficient in a pond I think. Growing up one of my neighbors had a pond, and fish just showed up. They did not put fish in it. I'm not sure what kind of fish they were, but we had fun catching them and throwing them back in the water Do you have any other details about your brothers pond? How deep, how wide, and how did he dig it? Did he hire out, or maybe use a backhoe? Our climate is similar to upstate NY, maybe a little cooler, but not much. NY has cold winters and warm summers like I do.
Trsturself, while my family and I enjoy the flavor of tilapia, our climate simply could not sustain them. I believe 50 degrees or lower is fatal for them. My current outdoor temp now is -4. Which would require lots and lots of wood to keep those fish warm... I appreciate your input though! We have read about aquaponics, and thing its a self sufficient dream! We are working bit by bit at self sufficiency. We have quite a way to go though.
Thanks much for the replies!
Usually an aquaponics system is in a greenhouse type structure so it stays warm and humid in there. People do it here in CO and it gets down in the negatives too (it was -16 just a few days ago).
