Georgia? Not that I know of. Last Thursday I made a presentation at Ft Valley State aquaponics workshop, they have an aquaculture program with a side interest in aquaponics. About 40 people came from all over the southeast, for the most part new to the concept, but otherwise serious about pursuing it on a homestead scale. No one made any mention of larger systems in GA. Nothing to approach Morningstar Fishermen or Travis Hughey.
The workshop could have been much better, but it showed the interest level, those who would drive a few hours on a weekday. You know the passion when you first heard of aquaponics? Made some good contacts.
