Aquaponic gardening is a more sustainable way to grow fish and plants for food. There are many advantages to feeding yourself with aquaponics.
Why It Matters
- Aquaponics combines aquaculture, or raising fish, with hydroponics, or growing plants without soil.
- Bacteria and worms are important parts of this system too.
- Only 10% as much water is used as in an outdoor garden.
- Aquaponic gardens are four to six times as productive per square foot.
- The fish and plant crops are organic.
- The system needs only a small amount of energy for a pump and aeration for fish.

- Hydroponics is a relationship between plants and fish that is beneficial to both. What does each provide to the other?
- What would kill the fish if they were left in a tank without any way of cleaning the tank?
- What happens to the nitrogen in fish waste as it cycles through the system? What is used as fertilizer for the plants?
- Why does an aquaponic system use only 10% as much water as an outdoor garden?
- Why doesn’t aquaponics need pesticides, herbicides or other chemicals?
