Detailed SR Function Description
A wide range of depths were suitable for 0+ stream/ocean-type Chinook Salmon captured in spring (Figure 21). The wide depth suitability may be reflective of both shallow water use by stream-type fry and a broader distribution of migrating ocean-type fish. Depth suitability for Fraser gravel reach fish is similar to the WUP curve for Chinook fry, except that suitability declines past 80 cm for Fraser fish (Figure 21).
Function Type
continuous
Stressor Scale
linear
