I am an American, currently living in Beijing. My name is Carey Ma. I am an Ecolonomists with over twenty years experience in off-grid/ automated living. The word ecolonomics was coined by a personal hero of mine; Denis Weaver. Ecolonomics is the promotion of sustainable alternatives that are economically profitable. Simply put, ecolonomics means maintaining natural resources in ways that are economically sound. I consult in all phases of Green living and explore the principles of environmental, economic, and social sustainability, to provide practical examples of how to apply them. I consult for: Architects, designers, city and community planners, land owners, factory owners, and greenhouse/ orchard/ farm owners.

I have a plan to establish a facility which will reduce the impact of agriculture on ecosystem functions and services by providing nature inspired, zero emissions, sustainable Agri-technology using integrated bio systems (IBS) in an urban/ peri-urban environment for the production of food & lifestyle enhancement amenities. My ultimate dream is to build a Hi-Rise Farm, each Farm feeding 10-30,000 of their neighbors while producing energy and clean water.

My nursery/ garden /farm is less than two acres yet both economically and ecologically sustainable and manages to feed a family of four with surplus to sell. I have been experimenting with Aquaponics, on and off since the late seventies and finally have a balanced schedule of nutrient flow.

Aquaponics is the first step in an integrated bio system. An integrated biosystem contains at least two biological activities or subsystems where nutrients in the form of by-products (waste from one sub-system) serve as resources or the input for another.

I make my own feed using algae, vitamin rich veggie leaves, earthworm & dry grub protein.

Hey folks, I am starved for information. Please Donate books, DVDs etc.

Hi guys, 

I know its a lot to ask but not being back to the States for seven years has depleted all my original resources. I really hate to sound like a beggar but...the reason I haven't been back is because I can't afford to.

Do you have any books, magazines or DVDs that you have finished with or just laying around?

Subjects I'm interested in are: Sustainability of any sort, popular mechanics/ science, ecology of any sort, any must read books, philosophy...anything meaningful to you, I'm sure I'd be interested too.

Are there any tools; hole saws, screwdriver bits you name it, (esp metric) that you don't use or have spares? I'd gladly take anything usable. Anything decent that is made in this country goes to export. Local tools are accidents waiting to happen.

I thank you my friends for reading this and hope you can help.


Hi guys, I'll be in Seattle next week (Oct 10 -20th) so anyone with books etc can send them to my friends house so I can carry them back to China instead of sending them here.

Please send to: Rand Will, Care of Carey Ma:12819 SE38th #401,Bellevue, WA98006


Thanks & Cheers.

Carey's News Letter / Report on 1013

Posted on November 19, 2013 at 4:35am 3 Comments

Hello to all my AP friends,

I sure have missed y’all! This has been an interesting and exciting year for me. Unfortunately we haven't been able to do any Aquaponics other than stock our new ponds. I just wanted to stop by and update anyone who might be interested, in what I have been doing.The following is a brief of what we did this year. *Pictures will follow later. Please look for them in Album named "TongZhao 2013".


As some of you may know, I am a self-proclaimed…


Carey's multi trophic aquaponics system

Beijing Greenlink Institute LLC

Multi-Integrated Agriculture & Aquaculture Systems (BIMIAAS) 


The experimental farm of Mr. Carey Ma is part of an interdisciplinary team of volunteers, working on the development of integrated multi-trophic agriculture & aquaculture (IMTAA) systems AKA (multi trophic aquaponics).


The goal of IMTAA or MTAp approach is to create a balanced…


One more step – Part two ~ Sorry, lots of words and no pics (at this time)

Good news! Merry X-mass all! On Christmas Eve, I received a call that lasted about four hours and in conclusion I got a wonderful X-Mass present in the form of a committed Angel Investor. Phase one will begin as soon as I finish negotiating and sign an agreement with the landlord, (hopefully within the next month).

Phase One will be concentrating on the forest pasture to increase my egg and chicken production from my current two hundred hens to a possible five…


One More Step!

Maybe dreams really do come true. I’m only in initial negotiations at this time (as of yesterday), and there will be a thousand and one hurdles to jump before I can actually claim the existence of my concept institute, “Ma’s Greensmart Institute”, but it finally has a glimmer of hope.


It seems that both ladies, Fate and Destiny have kissed my cheeks. My new farm will be located in the same village, no more than a quarter mile from my experimental garden. It is a fifty-acre…

Hi Carey. Are you still doing aquaponics in Beijing? I have a couple of friends who are interested in investing aquaponics project in China. I will go to China for a business trip this summer and would like to visit your farm if possible. I look forward to hearing from you. Thanks!

Carey, I am a master's student in Global Sustainability at USF Tampa. I am trying to implement closed-loop aquaponic systems in schools as a way to teach kids how to build the systems and plant, harvest, and troubleshoot them. As part of the grants that my team is looking at we must be able to quantify the amount of food produced in pounds and the amount of people that can be fed per square foot of space used for growing. I am coming to Shanghai and Beijing this summer 5/10-6/21/13. We are studying Chinese architecture and I am trying to develop an aquaponic greenhouse that harvest its own water. I finish my degree after the Fall semester 2013 and I am hoping to develop these systems through our grant team and make my career in aquaponics. I do not have a system myself but I grow at my apartment in pots. I do work on a system with my team at one of our team member's backyard and I am helping a local farmer in New Port Richey area to change from organic soil growing to aquaponics systems. Ok well I think thats enough for now but feel free to ask me any questions that you have. Thanks again for all your help!

hi carey!  good to know some people doing aquaponics in China.  Would like to learn more on a DIY basis. interested to know how you got started in China. WHere do you find materials? (there isn't much Home Depot or similar in SHanghai)

Hi Carey. Yeah, I can relate to that. Most of the busy-ness here amounts to me robbing Petar, to pay Paul, but I can think of worse things to be doing with my time. (Sorry this reply is about a month late, I don't much check my page). Hope all is well. Cheers.

Thanks, your pioneering efforts in China are an inspiration

Would be great to exchange information and experience while I develop a multi-story AP complex here in Boston.

Likewise, Carey. Good to hear from you. I think we are in twin circumstances on the opposite sides o the world. Too much work, not enough money, and too optimistic to let it all slow us down. I'll fill you in on my events later, busy right now. Cheers

Slow but moving. Will have plants in by weeks end.

Hey Carey,

Thanks for checking up on me. I miss you guys and the site very much. I glance through every once in a while. See you are staying active, I'm happy for that. Very busy here and don't get the time really. Still trying to get some land to practice/teach AP. Im making some progress and could be sooner than later. Hope youre doing well with the AP over there. Bye for now.

Slow but moving. Just started the cycle on my tank, added conditoners to speed up the proccess and picking up fish on the 8th.   Hoping to visit with a few locals who also have systems.   Been a real chalange gathering data but still at it. 

Thanks for asking. Hope all is well with you.

ola Carey Ma..posted a couple of drawings of our project on my wall since you were unable to open the blog.. Thanks for the 'feed' thread- you answered several questions I had re tilapia eating greens..etc. Our ponds are growing lots of green stuff these days..Wondering how much of it the fish eat..Seems to mostly grow in the shallows- maybe warmer water? Tested with PH strips the other day-about 6.5-if the ponds have heavy ammonia would they test out at 6.5?

Question ? Between the work you do on your farm(s) etc, the mail you do re this site etc,when do you sleep? Went thru your photos- like wow it appears you have many 'irons in the fire'- 

am amazed that your digesters have enough internal pressure to force out the sludge..Have you tried the sludge mixed with other plant waste in a cold (worm) compost?

Take your point re the billions eating veggies grown from sewage sludge..Lotta prejudice to overcome unfortunately. When we get hungry enough we'll get beyond that sorta thinking..
