Transcript of Aquaponics

What is Aquaponics?
Aquaponics is a sustainable food production system that combines aquaculture (snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in one environment.
How does it work?
Fish produce waste that turns into nitrates and ammonia. These aren't good for the fish if they build up too much, but there waste are great fertilizer for plants. As the plants suck up these nutrients, they purify the water.

Aquaponics History
Many cultures have made use of this cycle to grow better crops and nurture the fish as an additional food source.
Aztec Indians raised plants on rafts on the surface of a lake in approximately 1,000 AD.
The Aztecs made large rafts out of reeds and tree bark
They planted their vegetable crops on these floating rafts that they called "Chinampas"
When the plants matured, their roots grew through the soil and dangled in the water absorbing the waste from the fishes
Aquaponics Today
Aquaponics emerged from the aquaculture industry as fish farmers were exploring methods of raising fish while trying to decrease the use of land, water and resources.
Today many use recirculating aquaculture (plastic tanks)
These tanks allow you to grow and carry a lot more fish
Many farmers use the Aquaponic system to grow healthier crops
The Aquaponics system uses less electricity and requires less labor
Mari's Gardens
One of the many farms that have an Aquaponic farm
Plant Nursery
In Mililani Town
They produce Tilapia and Chinese catfish and utilizing water from that product to produce lettuce, beets, tomatoes, herbs, spinach, taro and cucumbers.
There method of farming is sustainable, organically certified and food safety certified.
Why is Aquaponics important?
With an Increasing world population
There are more houses and less land for farms
Don't have to use acres of land
Aquaponics eliminate the need for the costly synthetic nutrients that are often used in hydroponic systems
Synthetic nutrients are made up of fossil fuels, which isn't good for the environment
You don’t have to use pesticides when farming with Aquaponics
Conserves Water
Easier and faster way to grow fresh food
Aquaponics Video
Aquaponics good for the environment?
Instead of feces-filled water being dumped into our water system and causing problems downstream, it is used to grow plants, which is cleaned, and then used through the fish tanks.
Save electricity
Don't have to use fossil fuels
Doesn't take up much land
