RAS is widely used for rearing fingerlings, however, its ability to efficiently produce market-sized fish such as salmon remains a subject of debate.

In a typical recirculating aquaculture system (RAS), a series of treatment processes are used to maintain the required water quality levels and also to sustain the growth of cultured fish species, while maintaining very low water exchange rates. A critical aspect of the treatment process is biofiltration.
