Species Profile

Northern Brook Lamprey Saskatchewan - Nelson River populations

Scientific Name: Ichthyomyzon fossor
Other/Previous Names: Northern Brook Lamprey (Saskatchewan - Nelson population)
Taxonomy Group: Fishes
COSEWIC Range: Manitoba
COSEWIC Assessment Date and Status Change: November 2020
COSEWIC Status: Endangered
COSEWIC Status Criteria: B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v)
COSEWIC Reason for Designation: This small, nonparasitic lamprey has a very limited distribution in the Winnipeg River watershed in southeastern Manitoba. The number of mature individuals is declining based on observed reductions in extent of occurrence, area of occupancy, and number of locations, and an inferred decline in quantity and quality of aquatic habitat. These populations are exposed to threats, such as decreases in stream flows under current and future climates, and are very susceptible to anticipated increases in water temperature. Substantial recent targeted sampling, using both conventional methods and environmental DNA (sampling water to confirm presence of DNA from the species), now provides sufficient data to conclude that this species is at risk of extinction.
COSEWIC History of Status Designation: The species was considered a single unit and designated Special Concern in April 1991. When the species was split into separate units in April 2007, the "Saskatchewan-Nelson population" unit was designated Data Deficient. Status re-examined and designated Endangered in November 2020.
SARA Status: Schedule 3, No Status - (SARA Schedule 1 provisions do not apply)
Date of Listing (yyyy-mm-dd):

Protection

Federal Protection

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 Northern Brook Lamprey, Saskatchewan - Nelson River populations, 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.

Provincial and Territorial Protection

To know if this species is protected by provincial or territorial laws, consult the provinces' and territories' websites.

Documents

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 Report 2020 to 2021 (2021-10-12)

    Over the past year COSEWIC assessed a total of 66 wildlife species, of which 4 were assigned a status of Not at Risk. Of these 66, COSEWIC re-examined the status of 41 wildlife species; of these, 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 826 wildlife species in various risk categories including 369 Endangered, 196 Threatened, 239 Special Concern, and 22 Extirpated (i.e. no longer found in the wild in Canada). In addition, 19 wildlife species have been assessed as Extinct, 62 wildlife species have been designated as Data Deficient, and 202 have been assessed as Not at Risk.
