I don't believe aquaponics (or hydroponics) may be certified organic, which is all about soil health and a living balanced ecology. Aquaponics mimics a balanced ecology. is that enough?davep wrote:I'm not much of an aquaponics fan. For me it's an extension of the "soil as an inert recipient for added nutrients" approach.
I much prefer having living soil and diversity, but I guess you need a lot more space for that.
As for space; you still have to feed the fish chow grown outside the system on some land. So that is additional space that must be accounted for. It's all a question of calories, protein, nutrients, NPK, and the appropriate (for my climate, land configuration, money) conversion from soil/water/sun to necessary human nutrition. The critical nutritional issue is GLA, omega-3, and vitamin B. What is required of the homestead to produce these?
I would prefer a mix of chickens, rabbits, and goats but I'm less squeasmish killing fish. I am very interested in aquaponics, and hope to try the system in my new hoop greenhouse. Tilapia in the summer and trout in the winter. Raising the young is the hard part I guess.
