Recirculation aquaculture system - RAS2020

Krüger and Veolia offer a unique grow-out solution. RAS2020 is a flexible, module-based recirculating aquaculture system with optimised process logistic, low operating costs and reduced footprint.
RAS2020 is designed for a daily feed load of maximum 4,000 kg feed per day and an annual production capacity of 1,200 ton fish.
The RAS2020 is well suited for species such as salmon, trout, kingfish, sea bass, pike perch among others.
The fish are farmed in a controlled environment based on the state-of-the-art recirculation including water treatment technology ensuring stability to optimise growth, reduce feed conversion ratio (FCR) and improve survival. RAS2020 has brought in optimal flexibility in RAS systems resulting in minimum handling and moving of the fish.
The differences between RAS2020 and conventional RAS solutions
- Uniform adjustable flow velocity in the entire water column – similar water parameters in the entire tank volume
- Daily harvest without stress - easy transfer to purge tank
- No underground piping – less associated risks
- Less foot print - less civil works and cost of land
- Vacuum CO2 stripper - enhanced N2 and CO2 stripping
- Overview of production – central location with short distances
- Flexible production – adjustable tank sizes to secure optimal density
- High turnover – up to two tank volume though RAS per hour
- Prepared for additional ozone and oxygen injection
