Great insight and input...I appreciate your knowledge, opinion and forsight on the subject.

It still all comes back to the fact that large hydroponic systems or huge ones like the one in Az that raises gazillions of pounds of tomatoes a year are operational and showing enough profit to warrant staying in business, it seems to me that since you don't have to buy chemicals to grow the plants, what's holding someone with enough acreage and money back from venturing into the fray?

Yes, I know you still have to buy the fish food, but you also offset the cost of the fish food with the money from the fish...so basically still no cost there.

I don't have the bucks or land...all I have is 46+ years of knowledge and experience in the field of Aquaponics and Aquaculture and I am waiting for the other half of the equation to wake up and say let's make this dog hunt.
