Standardizing RAS
The solution lies in our standardized RAS concept
Salmon is an important source of protein. Today's salmon production faces significant challenges related to environmental impact, fish welfare and biosecurity, which have limited further growth in the industry.
Land-based salmon production based on RAS technology addresses many of these challenges. However, many projects have been characterized by high capital commitment, technical complexity and lack of operational predictability.
EcoFishCircle has therefore developed EFC mRAS - a modular and standardized RAS concept designed for commercial production. Our system combines proven water treatment with a robust and scalable system architecture, designed to reduce CAPEX, biological risk and operational complexity.
The core of the solution is our in-house developed management system, EFC Control, which provides a comprehensive overview and precise control over key processes and operating parameters. Together, EFC mRAS and EFC Control to facilitate stable operations, high operational performance and further scaling of land-based salmon production.

EFC mRAS
EFC mRAS is EcoFishCircle's modular recirculating aquaculture system, designed for stable and predictable commercial-scale salmon production. The system is built on a standardized architecture where each module functions as an independent production unit, while the solutions can be easily scaled and combined into larger facilities.
The EFC mRAS has a compact design with a centrally located biofilter, where all water recirculation is isolated to each individual tank. This provides a high degree of biological control, contributes to stable water quality and reduces the risk of cross-contamination between modules and the rest of the plant.
The technology has been developed based on practical operational experience and thorough engineering. The focus has been to reduce technical complexity, biological risk and investment costs, without compromising performance or flexibility. This results in a system that is robust in daily operation and well suited for further roll-out in new projects.
EFC mRAS integrates biofiltration, CO₂-removal, particle removal and oxygenation in parallel processes. This architecture facilitates targeted optimization of water quality and energy efficiency throughout the entire life cycle of the fish, while providing even load on the system components.
The system architecture is designed for efficient installation, operation and maintenance, with clear interfaces between processes and components. This facilitates standardization, repeatability and cost-effective implementation in commercial facilities.
EFC mRAS is tightly integrated with EcoFishCircle's management platform, EFC Control, which provides real-time overview and precise control over key processes and operating parameters. The interaction between system design and control is a key prerequisite for stable production and further optimization.
EFC Control
EFC Control is EcoFishCircle's management and monitoring platform, developed to provide full visibility and precise operational control in land-based salmon production. The system is designed to collect, structure and make operational data available in a way that supports stable production, efficient resource use and rapid decision-making.
The platform is tightly integrated with EFC mRAS and provides real-time insight into key processes and operating parameters, including water quality, hydraulics, load and system status. This enables continuous monitoring, early deviation detection and targeted action before small deviations develop into operational or biological challenges.
EFC Control is developed with a focus on operator friendliness and practical application. The user interface is clear and adapted to daily operations, while the system provides access to detailed data for analysis, optimization and further development of production strategies. This contributes to reduced operational risk and increased predictability in production.
The control system facilitates standardized operating routines and consistent practices across modules and facilities. This is a key prerequisite for scaling, where experiences and optimizations can be transferred directly between projects without the need for extensive adaptations.
EFC Control is developed as a flexible platform that can be further developed in line with production and customer needs. The interaction between management, system architecture and operational experience makes EFC Control to a key tool for ensuring stable production, high operational performance and continuous improvement in land-based RAS facilities.
A comprehensive framework for future land-based salmon production.
Holistic systems thinking
The EFC Concept represents EcoFishCircle's long-term and holistic approach to land-based salmon production, where technology, resource utilization and documentation are seen in context. The concept is based on EFC mRAS and EFC Control as the operational foundation, but goes beyond the production system itself and its management.
Circular resource utilization and energy
Through strategic partnerships and internal company connections, EcoFishCircle is working to further develop production as part of an expanded and more circular value chain. This includes close collaboration with HydrogenPro in electrolysis-based solutions for gas and energy production, as well as Gas2Feed, a sister company of EcoFishCircle, which develops solutions for utilizing CO₂ from production through bacterial fermentation.
In parallel, EcoFishCircle is working on processes for concentrating and recovering nutrients in wastewater, especially nitrogen (N) and phosphorus (P). These processes contribute both to further purification of emissions and to enabling the reuse of nutrients, including as a basis for algae cultivation and other bio-based value chains. Overall, this results in increased resource utilization, reduced environmental footprint and new opportunities for value creation related to the production system.
Traceability, documentation and trust
In terms of traceability and documentation, EcoFishCircle has exclusive use of biomarkers developed in collaboration with Queen's University Belfast. These natural and harmless biomarkers enable precise traceability and verifiable documentation of the fish's origin, production conditions and quality throughout the value chain.
The EFC Concept facilitates a high degree of transparency, documented fish welfare and automated reporting, and provides a robust foundation for regulatory compliance, quality control and trust in the market. Through standardization, integration and long-term systems thinking, the concept forms a framework for how land-based salmon production can be further developed – not just as a single facility, but as a scalable and resource-efficient part of the food production of the future.
