Detailed SR Function Description
Relationship between mean length of steelhead sac fry when hatched and dissolved oxygen concentration at which the embryos were incubated, for several water velocities during incubation and a temperature of 9.5 C. Newly hatched steelhead alevins were smaller and weaker when they had been incubated as embryos at low and intermediate DO concentrations than when they were incubated at higher concentrations. 100% of steelhead length is assumed to be 20mm.
Function Type
continuous
Stressor Scale
linear
