The tomato fish is not a genetically modified organism, but an aquaponics project of the Leibniz Institute for Water Ecology and Inland Fisheries (ITUC). Professor Werner Kloas and his team breed fish and tomatoes in a greenhouse at the Müggelsee in Berlin, saving water and keeping it all almost emission-free.
The tomatoes are irrigated in two coupled systems with the nutrient-rich fish water. According to Kloas, the project has the potential to contribute to securing the global diet. The prototype system “tomato fish”, developed by the IGB, can also be applied as a small urban farming project, but is also suitable for the large-area cultivation of foodstuffs.
