So you're interested in learning more about aquaponics? Well you've come to the right place! In this post we will be going into detail on how aquaponics works, why it is useful, and we will be providing several online resources for those who are interested in learning more about this amazing process!
Let's start with the basics. What does the word aquaponics mean? Well, "aqua" refers to aquaculture, which is the raising and breeding of fish in a controlled environment. "Ponics" comes from Latin, which means "to work." This type of growing utilizes only water, no soil. So aquaponics roughly translates to "working fish." This translation is on point, because in aquaponics, the fish do all of the work! They eat food provided by humans, which is excreted from their bodies in the form of ammonia. Ammonia is toxic to fish, so the ammonia either needs to be removed from the water via a water change (which is usually what is done in traditional aquaculture methods), or converted into nitrates via biofiltration by nitrifying bacteria. The nitrification process takes place on a molecular level, with these specialized bacteria processing the fish waste into nitrates, which are very good food for plants. The plants remove the nitrates from the water and at the same time clean the water for the fish. This closed loop system is what is known as aquaponics!
