aquaponics

There is a lively debate at Lawrence London's permaculture forum about Aquaponics. Toby is arguing that Aquaponics can be a legitimate part of Permaculture if it is appropriate to the context of the design. I would like to know if anyone here has utilized Aquaponics in their designs and if so, how close to self-sufficient you have become at providing feed for the fish from the property without off-property inputs. How did you achieve this? Or if you know of anyone who has approached achievement of this goal.

Great question! I'd love to know the answer as well.

I would probably redefine "the property" to mean your land and the neighbors you can easily walk/bike to visit.

I'd like to read this thread if you can point me to it.
