COSEWIC assessment and status report on the Atlantic Salmon (Lake Ontario population) in Canada

Assessment Summary


Assessment Summary – April 2006

Common name: Atlantic Salmon - Lake Ontario Population

Scientific name: Salmo Salar

Status: Extirpated

Reason for designation: Once a prolific species throughout the Lake Ontario watershed, there has been no record of a wild Atlantic salmon since 1898. The Lake Ontario Atlantic salmon was extinguished through habitat destruction and through over-exploitation by a food and commercial fishery. Attempts to re-establish Atlantic salmon through stocking have failed, and the original strain is no longer available.

Occurrence: Ontario

Status history: Last reported in 1898. Designated Extirpated in April 2006. Assessment based on a new status report
