Introduction to Acquaponics.

What is it?

Put simply, Aquaponics is the combination of aquaculture (raising fish) and hydroponics (the soil-less growing of plants) that grows fish and plants together in one integrated system. 

The fish waste provides an organic food source for the plants, and the plants naturally filter the water for the fish.

Start off with a fish tank, and buy your fingerlings ( baby fish) either Silver Perch or Barraminudi are a couple of excellent suggestions.

Attach plumbing to growing beds which contain a soilless medium such as Scoria, expanded clay balls ( Hydroton) even Perlite.

Each one has pros and cons for using it, for example, although Perlite is very light, it tends to wash away easily.

Water is reticulated ( circulated ) around the system so that the beds fill up with water constantly, then the water level drops as it's fed back into the fish tank.


The fish provide fish waste that feeds the plants.

The plants use this fish waste and filter out the water which is recycled back into the fish tank.

Robyn, says in here system of 5-6 growing beds, she never needs to flush out or replace the water other than to top it up due to evaporation.

There's more to it than that of course.
