Recirculating aquaculture systems in freshwater salmon hatcheries
With improvements in water recirculation technology, the time has come to seriously consider RAS in a freshwater salmon hatchery.

Feed management for RAS, part 1
RAS inputs and outputs are easily quantified, but even an efficient system will appear to have higher operating costs than a traditional pond.

Drum filter efficiency as particle separator in a recirculated system
Drum filters have been shown to be efficient in tests, although the effect of using different mesh sizes has not been clearly determined.

Treatment of recirculating waters with floating bead bioclarifiers
Bead filters compete very well as bioclarifiers and are used in combination with fluidized beds to tackle solids capture and biofiltration needs.
