Positive Bacteria and their use in Aquaponics Systems

Positive Bacteria and their use in Aquaponics Systems

Bacteria, the Third Element

Many people look at aquaponic systems and all they see is fish and plants. Much is written about this and many people define aquaponics as the “combination of fish and plants”. The fact is that there is a third, and equally important, group whose management is often completely ignored: bacteria!

Bacteria in Aquaponics

While most people acknowledge bacteria, usually the nitrifying genera, as being necessary to aquaponics systems there is often little acknowledgement of the true importance of many other species of bacteria and almost no methods are deployed for their management. Aquaponicists will often talk about nitrifying bacteria and while there are several genera of bacteria that will oxidise Ammonia to Nitrite and Nitrite to Nitrate the most common genus mentioned is Nitrosomonas and Nitrobacter respectively.

Positive Bacteria have four main benefits for areas like fish intestine lining and plant root tissue. They can be tip the balance of a system by:

  1. Preventing bad bacteria from taking hold. If the site is already occupied by a good bacteria then the bad bacteria cannot take hold.
  2. Promoting surface health. They can aid in breakdown of organic material that may get on the surface as well as actively assisting tissue health.
  3. Being antagonistic to bad bacteria. Many positive bacteria do not only prevent bad bacteria taking hold but actively antagonize bad bacteria so they are removed from the environment.
  4. Improving nutrient uptake and health. Many positive bacteria are major contributors to break down of nutrients that can be readily absorbed by they tissue.

Key facts:

1.Positive Bacteria
2.On both the fish intestine and plant roots there are normally good and bad bacteria
3.With the introduction of positive bacteria the balance is tipped toward the good bacteria
4.The good bacteria promote the health of the intestines or roots and are actively antagonistic toward the
bad bacteria
5. Good bacteria help promote the health of the fish gut or plant root and actively prevent bad bacteria getting a hold again

Adding Positive Bacteria

Good and Bad Bacteria  – On both the fish intestine and plant roots there are normally good and bad bacteria

Introduce Positive Bacteria – With the introduction of positive bacteria the balance is tipped toward the good bacteria

Bad Bacteria have to go – The good bacteria promote the health of the intestines or roots and are actively antagonistic toward the bad bacteria

Good Bacteria repel the Bad – Good bacteria help promote the health of the fish gut or plant root and actively prevent bad bacteria getting a hold again.
