Transcript of Aquaponics Presentation
Plants use the fish waste as nutrients
Waste free water is pumped back to the fish tank
As a form of waste, fish excrete ammonia through their gills.
A build up of ammonia in the water is toxic to the fish and basically useless to plants.
In the rocks of the grow bed, two nitrifying bacteria:
which convert the ammonia into nitrates.
Nitrates are extremely beneficial nutrients necessary in plant growth, and are harmless to fish.
More than 70% of the earth is covered in water, yet only 2.5% of that is fresh water. Most of the water used in farms seeps through the soil and is wasted (University of Michigan, 2006).
Aquaponics uses less than 10% of the water needed in normal plant growth.
Normal agriculture requires large amounts of land to be able to produce a profitable portion of food. The average amount of sorghum produced is 2,788.8 lb per acre.
In the city Milwaukee, Wisconsin a non-profit aquaponic farmer produces 40 tons of food each year on 3 acres alone.
2,000lbs = 1ton
Feeding the Poor
A small aquaponics system can feed a family of 4 for life.
A nonprofit organization in Milwaukee feeds 10,000 people who cannot afford to buy fresh produce.
Aquaponics Solving Global Issues
Making the System More Efficient
Siphon: When the water reaches a certain point, the siphon automatically sucks out all of the water.
There are endless ways to work the water piping, and we need to find the most efficient method.
These greenhouses are extremely efficient in maintaining the correct temperature for plants and fish because there are no corners to loose heat.
They are sturdier.
Have more area for light to enter through
How Aquaponics Works
Aquaponics will engage students in a hands-on environment to learn about plant life cycles, ecological issues, biology, advanced plant science, chemistry, physics, biotechnology, and many other topics.
Jesuit will be a leader in promoting sustainable farming, and the organic produce grown can be donated or sold.
A Normal System
The small system the two of us built only took us 10-14 hours of working over three weekends. It was relatively cheap and required very little man-power.
After talking about several different frame designs, we decided to go with a small "cage" that fit over the top to not waste space. The frame cost around $70 and took us around 4-5 hours to build.
We went online to Growerssupply.org and found a cheap covering for about $30. We then used a staple gun to fasten it to the wooden frame.
We put a small bin on top of a shelving system which rests over a larger tub. The top bin was used for plants and the bottom was used for fish.
We used Minos to produce the ammonia for the plants. We were able to get 13 total for an extremely low price. They eat very little and work great.
We got a tomato plant, a banana pepper, and two strawberry plants to start our system. Since we started than 3 weeks ago, we have seen massive change. Our strawberries cannot stop fruiting, the banana pepper has grown bigger and wider but our tomato is unbelievable.

There are many different locations around campus that have the neccessary requirements for an aquaponic system.
Promise of Peace
This is a non profit organization which strives to teach healthy living by building gardens in communities around Dallas.
I would love to incorporate this organization into our project by either donating produce or to teach kids about aquaponics and it's many functions.
