I know this thread is a bit old :oops: but I was searching for info on this aquaponics thing.
Does anyone know what fish are being used by that commercial place? Do they need a permit?
I know everyone said you can't keep trout, I wondered if perch would be ok?
Seems a shame to go to all the effort if you can't eat the fish in the end, and I understand perch are the best eating of the 'course' fish.
