Perfection all round – RAS systems with closed-loop circuits
Can you breed fresh fish without polluting our seas, lakes and rivers and without using growth-enhancing substances? The clear answer is: Yes, you can! Innovative RAS facilities (Recirculating Aquaculture Systems) make sustainable breeding possible. This will ensure that the next generation can continue to enjoy fresh fish by making the best use of energy and natural resources and minimising environmental impact.

“Circular economy is the future. It uses resources more efficiently, creates value in local areas, provides opportunities for new business models and strengthens economic resilience.”
Clean, safe, scalable - the key benefits of aquaculture systems
1. Closed aquaculture systems
RAS technology (Recirculating Aquaculture Systems) is based on closed water circuits and therefore enables land-based breeding methods. Water tanks are connected to complex filter systems that ensure a mechanical-biological water treatment. The facilities can be adjusted to the reflect the unique needs of each fish species raised.
2. Clean water
By using state-of-the-art filtration and oxygen enrichment systems, targeted oxidation processes and UV disinfection, 98 per cent of the water in FTN AquaArt AG RAS facilities is reused. As we can also ensure that the water is free of pathogens at all times, antibiotics and pesticides are not required.
3. Maximum resource efficiency
We’re committed to ensuring maximum energy efficiency and the use of renewable energy sources (e.g., photovoltaics, heat pumps, waste heat from industrial operations). By using innovative technology, we can guarantee an optimal cost-benefit ratio for every fish raised. Our use of by-products is another way we break new ground. Slaughter remains can be converted into animal feed and biogas, while wastewater and fertiliser surpluses can be used in agriculture. The CO2 produced can also be used in greenhouses, aquaponics and vertical farming.
4. Intelligent measurement systems
Our proprietary measurement technology makes it easy to operate FTN facilities. Our systems control the entire fish and energy technology, oversee the management of stock fish and keep you updated about the most relevant parameters through messages on the digital device of your choice. This means maximum production security, low operating costs and minimum energy and water usage.
5. Scalable solutions
Our RAS systems can be set up anywhere, irrespective of climate and geography. Your facility can be adjusted to reflect local demand and extended as required. Each model is designed as an independent production unit with all biologically relevant functions – allowing you to extend your fish farm flexibly over time.
Benefit from our expertise and experience - facility design and construction
FTN is a pioneer for indoor aquaculture. 30 years' experience at the Müritz fish farm as well as numerous international projects have allowed us to acquire in-depth knowledge on fishery biology and engineering.
We’re only too happy to share this expertise with our clients and ensure that you’re supported every step of the way – from planning and facility construction right through to its successful operation. This doesn’t only mean setting up an aquaculture system that is perfectly tailored to your location and desired fish species. Thanks to the most innovative automation technology, resource-saving energy management and proven Swiss engineering skills, our systems are also easy and efficient to operate.

For the highest possible operational safety - our control system
Our unique control system makes our facilities very simple to operate. It measures, monitors and controls all relevant fish parameters and the building technology itself. Stock management is also integrated directly into the system. Any variations from the target value will trigger an alert on the digital device of your choice (smartphone, tablet, desktop). The internally developed system ensures maximum production reliability, lower operating costs and minimum energy and water usage. Clients can also operate the system remotely, ensuring the best possible operational safety and optimal monitoring of your fish farm.

New opportunities in agriculture –circular economy
Regenerative agriculture, vertical farming and aquaponics all have one thing in common – they’re based on regenerative cycles and open up new opportunities for sustainable food production. FTN systems incorporate all three essential aspects of the closed-loop economy. The technical requirements governing filter systems and control technology. Efficient resource management with closed energy and material cycles. And the biological cycles in fish farming, water management and hydroponics. Our vision for the future is the development of holistic, sustainable ecosystems:
Aquaponics – fish farming and cultivation of crops through hydroponics
Vertical farming - the production of plant and animal products in multi-storey buildings
Urban Farming - food production in urban areas for local and regional consumption.
