Species Profile

Sockeye Salmon North Barriere-ES 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: C2a(ii)
COSEWIC Reason for Designation: After having been extirpated by dam construction in the 1920s, a new population was established through transplants. Although the population initially grew quickly, the fish now face a number of threats in both freshwater and marine areas which are causing habitat quality to decline. Since 1980, there has been a continuous decline to a low number today.
COSEWIC History of Status Designation: Designated Threatened in November 2017.
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 Sockeye Salmon Oncorhynchus nerka, 24 Designatable Units in the Fraser River Drainage Basin, in Canada (2018-10-22)

    Sockeye salmon is one of seven species of the genus Oncorhynchus native to North America. Adults have a slender, streamlined, silvery body with faint blue-green specking on the back and weigh an average of 3 kg (but in some cases over 6 kg). They undergo a distinctive transformation of external colour and body shape during their migration from the ocean to the freshwater ecosystem where they were born and grew as juveniles (usually a lake). The head becomes pale green in colour, the body can change to a brilliant scarlet, and the males develop large teeth and a sharply hooked jaw. The adults die soon after spawning and the developing embryos and then juveniles typically remain in freshwater for 1-2 years. Sockeye salmon exist as isolated populations and they evolve local adaptations to their freshwater environments. Note: This COSEWIC assessment was received by the Minister on October 15th, 2018.
