Hi there. I don't really have any background in commercial or hobby aquaponics so I can't really help with your question. What I do have is a serious interest in both. I have a friend who is putting up a 24 x 50 greenhouse and we are about to start exploring aquaponics on a small commercial basis. He has a background in construction and farming and I have and MBA and a background in management. I have been doing research on the commercial feasibility of aquaculture and I have not had much luck. I am not sure yet whether it is such a new concept that no one has expanded it to a large commercial scale yet, or if it has been tried and wasn't commercially feasible. I am very interested in what you find and if you have any input or find any information

Good Luck
