Atlantic Salmon Eastern Cape Breton population
Scientific Name: Salmo salar
Taxonomy Group: Fishes
COSEWIC Range: Nova Scotia, Atlantic Ocean
COSEWIC Assessment Date and Status Change: November 2010
COSEWIC Status: Endangered
COSEWIC Status Criteria: C1
COSEWIC Reason for Designation:
This species requires rivers or streams that are generally clear, cool and well-oxygenated for reproduction and the first few years of rearing, but undertakes lengthy feeding migrations in the North Atlantic Ocean as older juveniles and adults. This population breeds in Cape Breton Island rivers draining into the Atlantic Ocean and Bras d’Or Lakes. The numbers of adults returning to spawn has declined by about 29% over the last 3 generations; moreover, these declines represent continuations of previous declines. The total number of mature individuals in 5 rivers, thought to harbour the majority of the population, was only about 1150 in 2008. There is no likelihood of rescue, as neighbouring regions harbour genetically dissimilar populations, and the population to the south is severely depleted. A current threat is poor marine survival related to substantial but incompletely understood changes in marine ecosystems.
COSEWIC History of Status Designation: Designated Endangered in November 2010.
SARA Status: No schedule, No Status

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 - 2010 - 2011 (2011-09-09)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 during the past year assessing the status or reviewing the classification of a total of 92 wildlife species.
