White Sturgeon Lower Fraser River population
Scientific Name: Acipenser transmontanus
Taxonomy Group: Fishes
COSEWIC Range: British Columbia
COSEWIC Assessment Date and Status Change: November 2012
COSEWIC Status: Threatened
COSEWIC Status Criteria: B1ab(iii)+2ab(iii)
COSEWIC Reason for Designation: This large-bodied fish occurs in a small area and number of locations in the lower Fraser River Valley. It has declined greatly in abundance over the last 100 years and, although adult abundances now appear to be stable or increasing slightly, habitat degradation continues and fish are subject to mortality from by-catch in commercial salmon fisheries as well as mortality associated with a growing catch-and-release recreational fishery.
COSEWIC History of Status Designation: The species was considered a single unit and designated Special Concern in April 1990. Status re-examined and designated Endangered in November 2003. Split into four populations in November 2012. The Lower Fraser River population was designated Threatened in November 2012.
SARA Status: Schedule 3, No Status - (SARA Schedule 1 provisions do not apply)

Species that have been designated at risk by COSEWIC since the Species at Risk Act (SARA) was written must be added to Schedule 1 through a regulatory amendment. Information on this procedure is available in the Assessment section. If White Sturgeon, Lower Fraser River population, is added to Schedule 1, it will benefit from the protections afforded by SARA. More information about SARA, including how it protects individual species, is available in the Species at Risk Act: A Guide.

PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. Most of the reports not yet available are status reports for species assessed by COSEWIC prior to May 2002. Other COSEWIC reports not yet available may include those species assessed as Extinct, Data Deficient or Not at Risk. In the meantime, they are available on request from the COSEWIC Secretariat.

COSEWIC Annual Reports
COSEWIC Annual Report – 2012-2013 (2013-09-24)Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to “assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species”. COSEWIC held two Wildlife Species Assessment Meetings in this reporting year (October, 2012 to September 2013) from November 25 to November 30, 2012 and from April 28 to May 3, 2013. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 73 wildlife species. The wildlife species assessment results for the 2012-2013 reporting period include the following: Extinct: 0 Extirpated: 2 Endangered: 28 Threatened: 19 Special Concern: 19 Data Deficient: 4 Not at Risk: 1 Total: 73 Of the 73 wildlife species examined, COSEWIC reviewed the classification of 50 species that had been previously assessed. The review of classification for 26 of those species resulted in a confirmation of the same status as the previous assessment.
