South African Aquaponic equipment sources


South African Aquaponic equipment sources

With a growing number of South African members, I thought that it may be a good idea to start a page dedicated to finding equipment and consumables for aquaponic systems and to share the information with others in the group.

Hey guys thanks for the add!  I'm developing a proposal for a 1000L fish tank, 1 media grow bed, and 1 sump tank system to start our pilot program.  The plan is, after initially cycling and stabilizing the system, to add redundancies and efficiencies.  So our pilot will only have about 15 tiliapia to start for the one grow bed and our goal is to increase that number to 40 by adding adequate aeration, filtration, and solar power.  Not sure if anyone knows any viable water sources?  Can you treat water from the grid?  Hopefully there is a large fish feed supplier and you guys know where I can get some?  Last but not least, IBC Tote Containers do they exist in Africa?  Thanks in advance guys/gals

Hi Kobus,

Thanks for all the advice, it is quite difficult to find both info and products here in Gauteng.

I have 2 questions about fish:

My grow beds total a surface area of 4m2 and are 30cm deep. My tank is 3900 liters. According to the Rules of thumb I calculate that I should ultimately have 20kgs of fish. Given that I will most likely start with fingerlings I would like to know how many fish I should stock. I thought about 100?

Secondly, I have read that Talapia are known as Kurper in SA. Is this correct?



P.S. Any idea of fish suppliers in Gauteng, are Hartebeesport Fisheries still in business?

I found feed troughs from that I am going to use. They are 2m x 0.5 x 0.3 deep.

Kobus - Thanx, appreciate your input. I  am a wiser aquaponic.

Derick - the state of the roots is not a concern for photosynthesis at all.  The leaves are the primary site for the gas exchange you refer to and if anything, a moist surface will allow more CO2 diffusion out of a root than a dry surface.  But as stated, it is the leaves that are responsible for gas exchange.

Kobus. My concern is not of temperature but of what I was taught about the process of  photosynthesis in school. The plants are taking in carbon dioxide and giving off oxygen during the day and the reverse at night. At night the leaves give off carbon dioxide and I am assuming the roots as well. My concern being the fact that if the roots are too wet this will interfere with the plant metabolism. Are we saying that the 45 minute dry period is sufficient to avoid this situation?

Derick - all my systems run periodically or permanently through the night.  What is your concerns? Temperature drop during winter?  Most larger (commercial) systems are on all the time.  In terms of the functioning of the bacteria, they need to be kept aerobic, which means that if you starve them of circulation for more than a day, you could be in trouble.  You could circulate less at night, as the fish are not eating and ammonia build up would be lower than during the day, when they are feeding often, but for me there is no issue with pumping every 45 minutes through the night.

Is pumping the pond water into the grow beds at night a good or bad thing?


Comment by Kobus Jooste on July 25, 2011 at 10:11am

Derick - over here on the forum we have a lot of potential fish ideas.  I have used everything from guppies to tilapia.  If you want food fish, I think Cape Town will give you trout and tilapia.  Trout may need some careful placement for summer water temp.  Not sure how many hatcheries around you can still supply fingerlings.


Tilapia could be a bit harder to find but I will go onto the website of the Aquaculture Institute of South Africa ( and see if they have info on tilapia farmers nearby.  Your other food fish option is sharptooth catfish.  If you are interested, I'll suggest the same route as above.  You can also contact your local environmental management agency to determine if there are any regulations pertaining to the buying and transporting of fish that I am not aware of.


You have a resource at the University of Stellenbosch Aquaculture Institute to tap into as well.
