Selenium and Westslope Cutthroat Trout

View all records in the stressor response library
Species Common Name
Westslope Cutthroat Trout
Latin Name (Genus species)
Oncorhynchus clarkii lewisi
Stressor Name
Selenium
Specific Stressor Metric
Whole body selenium concentration
Stressor Units
µg/g
Vital Rate (Process)
System capacity

Life Stage

Season
All seasons
Activity
All activities
Geography
Alberta foothills watersheds, excluding National Parks
Function Derivation
Based on data from Yellowstone Cutthroat Trout; Empirical data; Correlative model; Published (peer-reviewed)
Transferability of Function
This function was developed for and applied to Westslope Cutthroat Trout but was based on a population model for Yellowstone Cutthroat Trout (life history parameters measured in the Snake River). It should only be used on other subspecies of Cutthroat Trout with caution.
Source of stressor Data
Athabasca Rainbow Trout and Westslope Cutthroat Trout values at this time are set to 0 but it is our expectation that monitoring from industry will have taken place and whole-body tissue concentrations would be available.
Function Type
continuous
Stressor Scale
linear
