Let’s talk aquaponics

Rebecca Nelson and John Pade have an aquaponic greenhouse in Montello, Wisconsin. They feed tilapia fish in tanks, the fish waste goes through a bacteria tank and then to plants suspended in the water. The plants take the nutrients out of the water which then cycles back to the fish tanks. There are no pesticides or chemicals used in the operation, the produce, mostly lettuce is sold to schools, grocery stores and customers within a fifteen-mile radius and so are the fish.
