Sockeye Salmon Widgeon (River-Type) population
Scientific Name: Oncorhynchus nerka
Taxonomy Group: Fishes
COSEWIC Range: British Columbia, Pacific Ocean
COSEWIC Assessment Date and Status Change: November 2017
COSEWIC Status: Threatened
COSEWIC Status Criteria: D1
COSEWIC Reason for Designation: This is a naturally small population which faces a number of threats in both freshwater and marine areas which are causing habitat quality to decline. The number of mature individuals was relatively stable from 1950 to 1990, and then declined considerably to a minimum in 2000. Over the past 3 generations the number of fish has returned to pre-1990 abundances. However, the small population size makes them vulnerable to stochastic events and increasing threats.
COSEWIC History of Status Designation: Designated Threatened in November 2017.
SARA Status: No schedule, No Status
