Aquaponics is the combination of aquaculture (raising fish) and hydroponics (growing plants without soil) that grows fish and plants together in one integrated system….More at The Ruttan Aquaponic Experience: What is aquaponics?
Just like in the picture to the right, the fish will produce waste and the microbes & worms will convert the waste to fertilizer for the plants. Which then the plants filter the water that returns to the fish.
A hydroponic system is a method for cultivating plants without soil, using only water and chemical nutrients.
So when you combine the root meaning of the words starting with hydroponics which means “water working” and aquaculture “Raising Fish) you have “Fish working” and that is exactly what goes on when you grow your fruits and vegstiable in an aquaponics system!
