Some time ago, Steve E. sent this article to me; my apologies for taking so long to share it with our readers. Backyard Fish Farm by Carla Wintersgill, from Canada’s Globe and Mail is about aquaponics, a combination of aquaculture (raising fish) and hydroponics (raising produce). From the article:
“In the symbiotic system, fish provide fertilizer for the plants, and the plants clean the water for the fish, eliminating water waste and making it the ultimate sustainable food source.”
If this interests you, check out BackYardAquaponics.com to learn more about this method.
I must note, however, that farmed fish have been proven to be nutritionally inferior to wild fish, primarily because the fish are not grazing for native food in their native habitat, much like the difference between feedlot beef and pastured beef or between eggs from factory hens and pastured hens.
