As many of you might already know, we are into the development of making commercial aquaponics systems (1) more sustainable, and (2) more productive. We believe that this is necessary for commercial success. We are currently not only involved in the already presented desertfoods project in Namibia, but also with a project in Kenya: the […]
About Simon Goddek
Simon is a PhD student in Aquaponics at the University of Iceland. Within the framework of his research he deals with system dynamics and mass balances, and examines the impact of remineralisation on the systems’ nutrient contents.

In a previous article, we have pointed out the challenges and opportunities of aquaponic food production systems in Namibia and other (semi-) arid regions around the world. We are proud to announce to be a partner of the desertfoods aquaponics project in Namibia that we will tackle together with desertfoods Namibia PTY, Göteborgs Universitet, Wageningen […]
Climate change and the increase in the phenomena of droughts require drastic measures in terms of innovative agriculture approaches to maintain food securities in countries with water stress. Wageningen University (i.e. the author of this post, and Prof. Karel Keesman) wrote this strategic report that addresses the necessity and potential of the implementation of multi-loop […]
As you guys might have noticed, we are currently running an experiment on the anaerobic remineralization potential of RAS-derived fish sludge. In order to clarify open questions regarding the impact of anaerobic effluents on plant growth, we have conducted a small experiment. In that experiment we compared the lettuce growth (as well as shoot:root ratios) […]
Today, Simon has started a lettuce growth experiment together with Tycho Vermeulen in Bleiswijk, the Netherlands. We are going to assess to what degree micro organisms in RAS water have an impact on lettuce growth by adding it to a hydroponic solution. The control group is a standard hydroponic nutrient solution for lettuce. We expect […]
There is lots of discussion going on on the internet and within academic worlds, whether decoupled aquaponics has a general advantage over conventional recirculating aquaponic systems. Figuring this out was our objective in the last years and led to the publication “Navigating towards Decoupled Aquaponic Systems: A System Dynamics Design Approach“. Following the KISS principle, […]
Yes – we are still alive, and no – we did not forget about posting on Developonics. We are currently just busy with publishing our research as well as already planing new aquaponics related projects. What else have we done? In March, Simon has been presenting the model on decoupled aquaponic systems that he developed […]
Simon, Boris, and Zala are currently preparing some aquaponics experiments at ZHAW in Wädenswil (Switzerland). Two of them comprise sludge digestion for nutrient and water recycling. We hope to see the performance of both digster types on the nutrient dynamics on the system. The results will be published in a open access peer-review journal. Below […]
Today, Zala and Simon have visited Urban Farmers in Basel. While cooking fresh tilapia and tomatoes from the aquaponics system, ideas have been exchanged with Andreas Graber and Ranka Junge.
We are currently running an experiment on specific nutrient uptake of lettuce grown in hydroponic, and both one and two loop aquaponic nutrient solutions. To guarantee that all relevant data is available after the experiment, proper data logging is an often underestimated factor. The excel logging file can be used and adapted by everyone for personal usage. You […]
