I live in Pensacola Florida and plan to retire soon. Starting a small commercial aquaponic system seems to be something I’d like doing during my retirement years. How much land and investment capital do I need to clear $100,000 Annually?
Also, Tilapia isn’t allowed in the panhandle section of Florida for some reason unless you can get a special permit from the state and I’m sure that won’t be easy. Therefore what fish type should I use for my area. Thank you for your time and looking forward to seeing what you folks can offer.

Robert,
Second item first, check with Florida Fish and Wildlife. You do not need a permit for blue tilapia in Florida, the hybrid you will need a permit.
The Commercial Aquaponics GOLD ebook covers all of the information on sizing, marketing and being successful in aquaponics. Rough figures, excluding land cost, for an income of US$100,000 will be in the range of US$250,000 to US$320,000. The ROI, Return on Investment is approximately 3 to 5 years, this assumes you are hiring all of your labor. If you and your family are the labor then the ROI is closer to 2 years.
We trust this information is helpful.

Dear Ms Davis
I just bought your book…. AQUAPONICS GOLD© and I can’t quit reading it. Any ideas how I get away from the computer? 🙂 I mean it.
As I begun my journey to build my first Aquaponics system several months ago….at the end of the day I always come back to your site. The book is great. The 17 secrets might look not much when you read it at first but I think those are some of the essential parts of understanding the aquaponic system.
Thank you so much for your “legwork” and dedication for the past 40 plus years.

Gregor,
Thank you for the kind words! May I suggest you print out Aquaponics Gold and place it in a binder. Most of our Aquaponics University students do exactly that with the Aquaponics University Course so they can refer to the information easily.
Congratulations to you on building your own aquaponics system. We call it getting your hands wet and it is THE best way to learn about the amazing technology first hand.
We also have two more books coming out, Commercial Aquaponics Gold and Backyard Aquaponics Gold. We’ll post the announcements on the website soon.
The best of luck to you.

Dear Mam/Sir,
I’m filipino, a technician working at Saudi Arabia. I’ve a 2 lots in the Philippines, one , sizes 1300 sq/meters, and the other one is 2400 sq./meters. I want to maximize my land with aquaponics to support my family (5 persons) and gainsome money . I just want to know much capital I need to corresponse to my lot area so that I can save. And where to I start ? Do your courses are online?
I hope you could help me regarding this matter thank you.

The area required to feed 5 people is only 12m2. This means that your plots can be utilized for commercial installations which usually start at approximately 1,000m2. A commercial installation of 1,000m2 including the land preparation, building, materials and the Portable Farms® Aquaponics Systems technology but NOT the land cost (you already have the land) will be approximately US$280,000 to US$300,000 and will feed 240 people. The ROI (Return on Investment) in most markets is 3 to 5 years. This means a payback of the original investment in 3 to 5 years. The income from a well run commercial PFAS installation is between US$80,000 and US$100,000 the first year and increases approximately 15 to 20% each year as the Operators and the installation become more efficient and the markets increase.
We trust this information is of help and we look forward to having you as a student. The AU Course is an email correspondences course and we have students all over the world.

Hi, I need help! I’m trying to build an Aquaponic Garden & here’s what I have & some things I’m looking for to
which I hope you can help me out::: I already have 2/ 275 gal. food grade totes. Will start with 1 for fish. I also
have 6/ 55 gal food grade barrels & 4 of them are CUT in 1/2-Longways. What I need from you, if you offer it
is the proper “Pumps” to cycle water thru my system. I’ll also need some fittings & valves. I need an air pump
to oxygenate the fish water(just to make sure they are kept well! And I may need some type of heater for the
winter here in north Texas! I just hope you have some pumps & parts to get me set up. I saw some other
worm items & I think some filter ideas that will be good for a “Clean system”!
I do hope you can help me. Sincerely,

If you want to use a cobbled together system you need to follow some other system besides Portable Farms® Aquaponics Systems. There are literally millions of references on the Internet that will show you how to put together a homemade system. The Portable Farms® Aquaponics Systems for small and backyard installations is only available by taking the Aquaponics University Portable Farms Aquaponics Systems Course© where we teach you how to build a system in a climatically adapted structure and operate it successfully.
Good luck in all of your endeavors.

Vinit,
There is a process we have designed to help you arrive at the amount of investment for your particular project:
To better assess your project and offer answers that are timely and relevant to YOUR unique situation, please answer the following general questions related to your project and we’ll get back to you ASAP. Some of the questions may be redundant, answer them anyway.
1. What size project is your group planning to build? ¼ acre? 1 acre? Etc.
2. What state, country or territory is your project targeted for installation?
3. What is your projected time frame to begin your project? 90 days? One year? Etc.
4. What project of this size, in any arena, has your group accomplished in the recent past? In other words, can your group actually build this installation?
5. Is your funding in place? That means your group could pay cash for the entire installation TODAY. If not, do you have a target date for that available funding for the project?
6. Have you explored the marketing study for selling the food Portable Farms is capable of growing? This means, you have actually talked the chefs, food managers and buyers and have solid commitments from them to buy the production from your installation.
After completing the above responses, please return them to me and I’ll send you the 5 Phases information.

J-N,
The Portable Farms® Aquaponics Systems can be installed anywhere a climatically adapted structure is available. There are a growing number of PFAS installations in Canada. The fish we recommend is tilapia and most people feed them a commercial tilapia/catfish chow. They are herbivorous and can be trained to eat duckweed, lettuce, zucchini and other plant material, even coffee grounds.
There are many ways to heat and cool the interior of the structure. One of the reason the Aquaponics University Portable Farms Aquaponics Systems Course© was developed was to insure success in virtually any climate by outlining the requirements of the plants and fish. Yes, it is possible and the PFAS owners in Canada are very happy with their installations.

Hi,
My name is Savannah and I am an 8th grader at Clinton Middle School. We have our own aquaponics system but it doesn’t seem to be working that great. Last year we bought 50 goldfish and 49 of them died in 14 days. We think it is the PH levels.Here are some notes that might help. After evaporation of chlorine from tap water, pH rises from about 7.5 to 9.0. pH optimum: 7-8
Adjusted pH with vinegar to 7.2. Within 4 hours pH increases to 8.0 and then within 24 hours 9.0.
Britta Filter lowered pH to 6.0. Within 4 hours at 7.5 and 24 hours 8.8.
Reverse osmosis, ph 7 → 8.8 (24 hrs) Water that has been forced through a special membrane under pressure. It is a slow process that produces virtually pure water. This water requires remineralizing with essential elements before use in aquarium, but will be free of phosphates, nitrates and other nasty chemicals.
Kenosha water pH 7.5 . Sealed stayed
Room 4 – 8.8 after about 1 week
Aquaponics Lab – 8.8 -9 in 24 hrs.
Testing with and without gravel had no effect.
We were wondering if you could maybe help us. Please let me know asap if you have any information on how to help us. Thank you!
Sincerely,
Savannah
Author
Savannah,
You teacher asked the same question. Use a product called pH Down to reduce the pH in your system. You way have to check it every day for a while. Do not use RO water. Use tap water, let it sit for a full day or put in Vitamin C 5mg per gallon to take out the chlorine. Without fish the pH will go up to the level in the water use and the above as evaporation pushes it up. That’s the best I can do for you because I have no idea how much water is in your system, what the turn over rate is and what plants you are using.

I also live in Central New York. I have two questions: 1) I’m assuming that the water for the fish has to be heated in the winter. How much does that mass of warm 70 degree (+ or-) water contribute to the warming of the air in the greenhouse? 2) What is the rationale behind using a gravel type growing medium rather than the channels that are so common with commercially available systems?
Thanks.
Author
Richard:
The fish tanks are insulated and so the water is only exposed to the gravel, not the air, in the space. The warm gravel does contribute to the temperature, but not as much as one would expect. The plants love the warm, nutrient laden water on their roots.
We have had fantastic results with the gravel medium filled Grow Trays and our system is used to treat the water, the channels are not performing that function.
I trust this helps in some way.

We have an 1860s farmhouse in Central New York State… Building a climate controlled greenhouse for NY is a little cost prohibitive for us, but we have a completely unused basement that only houses our furnace and hot water heater. (approx 750sf) However, being an old farmhouse, the basement tends to be damp, has a dirt floor, and may prove challenging to keep “bug free”. Also, from time to time (once or twice a year), heavy enduring rains can result in a few inches of water in it as well. Is it conceivable that an aquaponics system could survive in such a space? It would be nice to finally find a use for the basement.
Respectfully,
Neil
Author
Neil:
Having been raised in Central New York, I understand exactly what you are facing. Two suggestions to implement, IF you want to use the space for a Portable Farms® Aquaponics Systems. 1) Put in a sump pump with a float valve in a sump hole. 2) Pour a concrete slab across the entire space to keep it cleaner.
The PFAS Modules are 36″ off the ground so they will not be bother by the moisture, but the space will have to have venting to the outside or upstairs to keep the moisture in the basement at a reasonable level. In the winter, open the basement door and have a fan
blowing up the stairs
. In the summer have a window fan SUCKING the air out of the basement.
Good luck. You need to take the AU Course first.

Good Afternoon,
I am currently a year 12 student at Brighton Secondary School and planning to base my Research Project within Brighton Primary School’s Produce Garden.
I have been given the opportunity to manage an aquaculture system for Brighton Primary School’s Produce Garden. The project will involve researching, designing and organising a commercial grade aquaculture/aquaponic system. This project is for students to be educated in the science and business of cultivating marine or freshwater food, which may include varieties of fish or shellfish. This is not only an important part of my schooling, but also a valuable project within BPS.
What type of aquaponic system design would you think would best suit an indoor area that young students could observe or be involved with, and why??
Author
Clare,
There are literally millions of pages of information on the Internet about aquaculture and aquaponics. You will have to choose the system best suited for your specific needs and outcomes. A commercial Portable Farms Aquaponics System is not a teaching tool, it is a high intensity food production facility. Start small with fish tanks, grow lights and grow beds and see how the systems work in your indoor facility.
I trust this information is of help to you in some way.

Are all the material used in your system chemical free? Most sites say to use plastic pipe and plastic totes for the aquaponics, but most plastics give off harmful chemicals that I don’t want to get into my plants or fish. I would also like to know what the price would be for two of your units, one to feed three people and one that would feed twenty people? I live in Alaska so the thought of having healthy food year round is very appealing to me! Thanks for your time and your inspiration! Sue Ann Richards

Sue Ann,
Nothing is chemical free. This system is probably not for you. It uses PVC pipes, plastic fish tanks and plastic liner so you could not eat the output anyway. The figures on output are on the website and to buy two will require you taking the Aquaponics University Portable Farms Aquaponics Systems Course©.

Dear Colle,
I have a green house measuring 500 sq.meters and would like to try aquaponics in about 250 sq. meters. After having tried it out and if successful, I would like to expand it in the entire 500 sq. meter polyhouse.
I would appreciate your giving me an idea of what I can begin with and how much investment I would have to make in the first phase (250 sq. meters) if I bought the entire system from you.
I look forward to hear from you soon. With regards,

Hello, I suppose salmon is out of the question for me, but I was wondering if you could grow another type of fish other than salmon, tilapia and catfish, if so what kinds of fish would you suggest?
Thank You,
Coby
Author
Coby,
The fish that are the easiest and least expensive to raise are freshwater, warm water herbivores. Carnivores require animal protein to grow well. Some fish food formulations are now available for them, but we are not familiar with their cost or effectiveness. Perch is a growing favorite, but require animal protein which is mostly in the form of ocean fish ground up and powered, contributing to over harvesting of the oceans. Tilapia are very easy to raise, are readily available, taste great and have a standing market.
This may not be what you wanted to hear if your favorite fish was not mentioned, but that is the state of the industry today.

Hi, been reading alot about your systems, what kind of cooling do you use for growing salmon? I’ve been searching the internet for pictures of your systems and talking to people but as far as i can tell there is nothing…? alot of people are intrested in this kind of system and growing salmon but they all say it’s impossible to grow salmon and make profit, the adult fish need salt water and this would be no good for aquaponics… I’m thinking of building my own system with hot and cold tank and some kind of heat exchange to minimise the running cost
http://aquaponicscommunity.com/forum/topics/refrigeration-to-heat-and-cool-fish-tanks?commentId=4778851%3AComment%3A292387&xg_source=msg_com_forum

Author
Dave,
Thank you for your inquiry into the feasibility of salmon aquaponics. For backyard or small installation, as another person in the forum pointed out, if there is no profit it, then it is only a hobby. In the case of salmon aquaponics it is not financially viable and will simply be a fun and frustrating hobby.
For commercial operations the key is to figure out an economic way to COOL the water. In northern latitudes in is MUCH EASIER to cool water than is hot climates. When we receive inquiries from locations such as Dubai or Nigeria or Haiti we carefully point out that heating the water and the space is almost never a issue, it is the cooling that requires the big bucks. We express a similar sentiment for people in Northern Canada, Finland and Alaska that they need to have a relatively inexpensive source of energy to insure enough heat if they are using tilapia or catfish. In the cool climates retaining the heat in the water is easier because they can use insulated tanks.
When we are approached by a company serious about a commercial salmon aquaponics installation in a cool climate we show them exactly what is involved and how much it will cost. These installations start in the US$250,000 and up range. There is not enough money in the backyard or hobby arena of salmon aquaponics for anyone to make a profit and Portable Farms LTD is in business to make money.
I trust this addresses what you were asking of us.
