Wild Salmon Policy Primer
- 1. Wild Salmon Policy CANADA’S POLICY FOR CONSERVATION OF WILD PACIFIC SALMON The goal of the Wild Salmon Policy is to restore and maintain healthy and diverse salmon populations and their habitats for the benefit and enjoyment of the people of Canada in perpetuity.
- 4. Implementation of the Wild Salmon Policy The map shows the watersheds (coloured areas on map) associated with the 13 Ocean Zones in BC. Note that the Puget Sound zone, which is comprised of the headwaters of the Skagit River in Canada, does not support migratory (anadromous) Pacific salmon.
- 5. Implementation of the Wild Salmon Policy The map shows the 26 Freshwater Zones within BC with anadromous salmon.
- 6. Implementation of the Wild Salmon Policy This map shows the 33 Joint Adaptive Zones within BC that have anadromous salmon. Each zone is a unique pairing of the Freshwater and Ocean Zones.

- To meet the conditions for benchmarks described above, we suggest four classes of indicators, the first of which, abundances (production), is clearly described in the WSP as one approach for assessing status (p. 17). To minimize COSEWIC listings (the second condition), we suggest two additional classes of indicators: time trends in spawner abundances and distribution (the later is also being suggested in the WSP as an indicator of status). Although COSEWIC criteria do not explicitly include fishing pressure relative to sustainable levels (i.e., relative to intrinsic productivity of the stock), we include that as a fourth class of indicator to assess likelihood of continued trends in abundances (declines or increases) given current fishing effort That fourth class differs from the first three in that it reflects an external stressor instead of an intrinsic property of the population.
- This figure illustrates the hierarchical framework that relates indicators, quantifiable metrics within classes of indicators and benchmarks on each metric. We identified candidate metrics and benchmarks drawn from the scientific and management literature
