Species Profile

Chinook Salmon Lower Fraser, Ocean, Fall population

Scientific Name: Oncorhynchus tshawytscha
Other/Previous Names: Chinook Salmon (Lower Fraser, Ocean, Fall)
Taxonomy Group: Fishes
COSEWIC Range: British Columbia, Pacific Ocean
COSEWIC Assessment Date and Status Change: November 2018
COSEWIC Status: Threatened
COSEWIC Status Criteria: Meets Endangered, A2acd, but designated Threatened, A2acd, because the longer time series shows lesser decline.
COSEWIC Reason for Designation: While the calculation of decline rates is complicated by hatchery releases from 1981 to 2004, this fall run of chinook spawning in the lower Fraser River has steadily declined in abundance. The abundance data over all available years was thought to best represent natural spawner abundance. Declines in marine and freshwater habitat quality, harvest and ecosystem modification in the lower Fraser estuary, are threats facing this population.
COSEWIC History of Status Designation: Designated Threatened in November 2018.
SARA Status: No schedule, No Status
Date of Listing (yyyy-mm-dd):

No schedule - No Status

COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Chinook Salmon (Oncorhynchus tshawytscha) in Canada (2019-10-09)

    COSEWIC assessed the status of 16 of 28 Designatable Units of Southern British Columbia Chinook Salmon in November 2018. Those DUs were considered to have received only relatively small levels of artificial supplementation over the past three generations, or were previously considered by the Department of Fisheries and Oceans Canada to be Data Deficient. The results of the assessment are provided in this report. Note: This COSEWIC assessment was received by the Minister on October 15th, 2018.

Response Statements

  • Response Statement - Chinook Salmon, Lower Fraser, Ocean, Fall population (2020) (2020-01-07)

    COVID-19 and the consultations on the listing of species at risk As a result of the COVID 19 situation, it may not be possible to have in-person meetings. We will work to ensure that all the known, potentially affected parties have the opportunity to contribute to the consultations and that the consultation process is flexible and sensitive to the current context. While the calculation of decline rates is complicated by hatchery releases from 1981 to 2004, this fall run of chinook spawning in the lower Fraser River has steadily declined in abundance. The abundance data over all available years was thought to best represent natural spawner abundance. Declines in marine and freshwater habitat quality, harvest and ecosystem modification in the lower Fraser estuary, are threats facing this population.

COSEWIC Annual Reports

  • COSEWIC Annual Report 2018 to 2019 (2019-10-09)

    Over the past year COSEWIC assessed a total of 56 wildlife species, 2 of which were assigned a status of not at risk. Of these 56, COSEWIC re-examined the status of 25 wildlife species; of these, the majority (80%) were reassessed at the same or lower level of risk. To date and with the submission of this report, COSEWIC’s assessments now include 799 wildlife species in various risk categories including 356 endangered, 189 threatened, 232 special concern, and 22 extirpated (that is, no longer found in the wild in Canada). In addition, 18 wildlife species have been assessed as extinct, 59 wildlife species have been designated as data deficient, and 199 have been assessed as not at risk.
