Oh, Rob's great. Very down to earth, great guy to talk to if you're thinking of doing aquaponics. Australia was home to a lot of the successful, early internet aquaponic groups, and it still shows in searches and forum listings. I don't think Rob himself has been doing this any longer than I have, but he's in a year-round growing environment and has certainly put more money into than I have (he's also a lot more personable and charismatic!). I always enjoy discussing aquaponics and permaculture with him.
There's a lot going on these days stateside, with strong communities in Colorado, Hawaii, and elsewhere, and a number of semi-professional groups that you can join. This guy (also named Rob) has done some good stuff on youtube: https://www.youtube.com/channe...
Here on garden.org we've had a few threads on the subject:
The thread "Aquaponics...Anyone tried it?"
in Texas Gardening forum
The thread "Aquaponics"
in Permaculture forum
And Dave did a podcast:
I could point you at other resources if those don't have what you're looking for. This is the second thread on the subject I've seen here in the Ponds and Water Gardening forum, though we didn't get very far in the last one. With aquaponics' overlap with pisciculture and water management, I think discussion here is as good a place as any.
Here's a chop and flip we did for the local Makerspace last year. Not sure why I never took any picture once everything was planted and filled in. They added a top off tank, monitoring sensors, an autofeeder, and a suncover. We'll probably set it up again when the weather warms. If anyone's interested, I can post about my own systems as I rebuild them this year.
