Detailed SR Function Description
For Rainbow Trout fry, there is good agreement between the Fraser HSC and WUP curves for both depth and velocity. The Rainbow Trout sample size of Rempel (2004) was relatively low (n=111); hence, we have adopted the WUP curves as the final HSC for 0+ Rainbow Trout in the Fraser River gravel reach. Fry show highest use of shallow and low velocity habitats over gravel-sized substrate.
Function Type
continuous
Stressor Scale
linear
