to have enough fish to be self reliant, a pond would probably be better, as it can be bigger and "can" survive with less human maintance. Just my thought. With Auquaponics, at the very least you will need to pump water back up to your veggies, and also feed the fish.
In a pond, you dont need any electricity if you are lucky, and the fish culture can be curved to be self suporting.
Just a thought!
More water = mare capable area of raising fish.
Your barn idea sounds pretty cool too. How "small" is it? and how big would you make your tank or tanks?
