Aquaponics: The process
Aquaponics is a process that combines the rearing of fish in an aquaculture system and the cultivation of crops using a hydroponic system. There are different approaches to bringing the nutrients to the plants.
Here you will find an overview of the different types of planting.

Such a system is always a closed circuit for fish production and a hydroponic system for plant cultivation. The system works by using the excreta from the fish farming as nutrients for plants. This is done automatically in our systems via dosing systems. By means of an appropriate control for nutrient supply - which is optimised for the respective selected plant species and the development phase. The closed cycle means that far more than 90% of the necessary nutrients, i.e. investment, can actually be found in the two end products (vegetables & fish).
In contrast to soil-bound planting, there are the following advantages:
- High yield: 500m2 yield up to 8 tons of fish and 16 tons of tomatoes per year.
- Minimal space requirement: profitability from 500 m2
- Weather independence: year-round operation and yield
- Independence from precipitation: closed cycle
- Very low water consumption
- No pesticide use
- No herbicide use
- No use of medicines
- No damage to groundwater: closed cycle
