The primary difference between RAS and traditional fish farming lies in their environmental approach and location. Recirculating aquaculture systems (RAS) operate on land using closed-loop water systems that continuously filter and reuse water, whilst traditional fish farming typically occurs in open waters like seas or lakes. RAS technology reduces water discharge into natural water bodies through controlled conditions and closed-loop water reuse.
Why is Finnforel’s trout farming environmentally significant?
Finnforel’s land-based trout farming operations utilise advanced RAS technology to create a closed-loop system that reduces direct environmental interactions compared to open-water fish farming methods. The approach is designed to limit specific categories of environmental pressure associated with conventional aquaculture.
By operating entirely on land, the system is engineered to prevent fish from entering wild populations, limit pathogen transfer to native fish species, and avoid the accumulation of waste materials on ocean floors. This controlled environment allows water quality to be continuously monitored whilst reducing contact with surrounding ecosystems.
Production location also affects transportation distance. By producing fresh trout close to consumers and delivering to shops on the same day, Finnforel reduces the transport distance compared to imported fish products. This local production model is one operational factor that affects associated transport emissions.

How does the RAS recirculating water system work in Finnforel’s production?
Finnforel’s RAS technology operates through a closed-loop water system that continuously purifies and recycles water throughout the production facility. The system maintains water quality through multiple filtration stages, including mechanical filtration to remove solid waste, biological filtration to process dissolved nutrients, and additional water treatment to maintain conditions suitable for fish growth.
Temperature control is a core component of RAS operations. The system maintains consistent water temperatures year-round, creating stable growing conditions regardless of external weather patterns. This controlled environment supports fish growth rates, feed conversion, and reduces stress on the fish population.
The Varkaus facility illustrates the operational scale of modern RAS technology. The facility produces three million kilograms of trout annually whilst using less water than flow-through farming methods. The recirculating system reuses over ninety-five percent of the water, requiring only minimal fresh water input to replace what is lost through evaporation and system maintenance.
What does responsibility mean in Finnforel’s fish farming?
Finnforel’s aquaculture operations are built around a defined set of operational practices aimed at reducing specific environmental pressures at each stage of production. The complete production chain, from healthy roe to fresh fillets, is structured to maintain quality control whilst limiting waste and resource use at each stage of the process.
The operational principles focus on several key areas:
- Reduced transportation distance through local production facilities
- Reduced food waste through efficient processing and same-day delivery
- Measured feed conversion rates reducing resource consumption
- Zero discharge of waste materials into natural water systems
- Energy use managed through closed-loop production methods
The integration of production facilities creates additional operational efficiencies. The Hollola breeding centre specialises in producing broodstock and juveniles specifically for RAS environments, whilst on-site processing capabilities reduce handling steps and support freshness. This vertical integration reduces transport between facilities and maintains product quality throughout the supply chain.
How does Finnforel reduce environmental burden compared to traditional fish farming?
Traditional fish farming methods often rely on open-water systems that interact with marine ecosystems through waste discharge, chemical treatments, and the possibility of fish escapes. Finnforel’s RAS approach contains all production activities within land-based facilities, removing several of these specific interaction points.
Water usage is one measurable operational difference between the two approaches. Traditional flow-through fish farming requires continuous water exchange with natural water bodies, which can affect local water quality. The recirculating system uses minimal fresh water input whilst maintaining stable growing conditions through continuous filtration and treatment.
Transport distance is a further operational difference. Conventional aquaculture products are often transported over long distances, sometimes internationally, before reaching consumers. Finnforel produces fresh trout near consumption areas, which reduces transport distance and the associated fuel use compared to imported alternatives.
What products does Finnforel offer as a result of its farming practices?
Finnforel’s farming practices result in trout products available through its established brands. The LOHI brand offers fresh trout fillets in both individual and family packaging sizes, along with alder-smoked fillets that reflect the taste profile achieved through the controlled growing environment.
Saimaan Tuore focuses specifically on domestic markets, providing locally-produced trout that supports regional food supply and reduces reliance on imported fish. This brand reflects the connection between defined production methods and food products that consumers can trace to a known origin.
The processing facility in Hollola is designed to minimise handling steps from harvest to packaging, supporting freshness and quality. Integration with feed production ensures that fish receive nutritionally specified diets formulated for RAS environments, which contributes to fish health and final product consistency.
Why choose Finnforel’s trout?
Choosing Finnforel’s trout means selecting a product from a defined, land-based, closed-loop production system that limits specific environmental interactions associated with open-water aquaculture. The RAS technology used demonstrates that modern fish farming can meet consumer demand whilst operating within a controlled, measurable production framework.
The operational approach delivers product freshness, consistent quality, and support for local food supply chains. The same-day delivery model ensures that consumers receive a fresh product from a domestic source with a shorter supply chain than imported alternatives.
For businesses and organisations interested in traceable sourcing, Finnforel’s products represent a domestically produced fish supply from a defined production system.
