There is a genuine need for healthy and sustainable food systems. As our population grows, researchers and food scientists are searching for ways to grow enough healthful food to feed the growing population. Experimenting with the food systems our ancestors used such as aquaponics combined with modern day technology, innovators have the ability to design highly-efficient ways to produce enough healthy food to feed our growing populations.
What is aquaponics?

The term aquaponics comes from fusing aquaculture (fish farming) and hydroponics. Hydroponics grows plants in a nutrient solution and water rather than soil. Withaquaponics, the nutrients are derived from fish waste byproducts rather than the soluble nutrients used in traditional hydroponics. These soilless growing methods are both resourceful closed-loop systems.
Aquaponics was used by the ancient Aztecs in the construction of vegetatedchinampas floating islands. It is an ecologically applied agriculture production technique that is emerging for biofiltration used in combination with commercial recirculating aquaculture systems.

Fish used in aquaponics
There are a variety of aquaponic fish that can be used with aquaponic systems. The type of aquaponic fish chosen depends on water temperature, pH, and a personal preference between edible fish or non-edible fish. More common aquaponic fishoptions are:
1. Arctic Char
2. Barramundi 
3. Bass
4. Goldfish
5. Koi
6. Murray Cod
7. Tilapia
8. Trout
