Species Profile

Chinook Salmon Southern Mainland Boundary Bay, Ocean, Fall population

Scientific Name: Oncorhynchus tshawytscha
Taxonomy Group: Fishes
COSEWIC Range: British Columbia, Pacific Ocean
COSEWIC Assessment Date and Status Change: November 2020
COSEWIC Status: Threatened
COSEWIC Status Criteria: D1
COSEWIC Reason for Designation: Mature fish in this population spawn in tributaries to Boundary Bay such as the Serpentine, Nicomekl and Little Campbell rivers, in southern British Columbia. This wildlife species occurs in highly altered freshwater and marine habitats. Ongoing low marine survival, bycatch, and fish culture effects are cumulative threats to the remaining wild fish. Hatchery releases are ongoing and have included fish from other populations, threatening the genetic integrity of the few remaining wild fish. While hatchery production has allowed the total population size to increase, a consensus of expert opinion estimates fewer than 1000 mature wild fish remain.
COSEWIC History of Status Designation: Designated Threatened in November 2020.
SARA Status: No schedule, No Status
Date of Listing (yyyy-mm-dd):

No schedule - No Status
