Detailed SR Function Description
Velocity suitability is maximal between 30 and 55 cm/s, which is greater than for 0+ Rainbow and similar to the WUP Delphi curve. There is good agreement in substrate utilization between the Fraser River data and all comparable data in the literature, with increasing use of larger substrates.
Velocity units converted from cm/s to m/s.
Velocity units converted from cm/s to m/s.
