Recovery Strategy for the Shortnose Cisco (Coregonus reighardi) in Canada

1. COSEWIC species assessment information

Date of assessment: May 2005

Common name: Shortnose Cisco

Scientific name: Coregonus reighardi

Committee on the Status of Endangered Wildlife in Canada (COSEWIC) status: Endangered

Reason for designation: Endemic to three of the Great Lakes, this species was last recorded in Lake Michigan in 1982, in Lake Huron in 1985, and in Lake Ontario in 1964. Although it has probably disappeared throughout its range, searches for this species have not been extensive enough to declare the species extinct. The species’ apparent demise is suspected to be the result of commercial overfishing and possibly competition or predation from introduced species.

Canadian occurrence: Ontario

COSEWIC status history: Designated Threatened in April 1987. Status re-examined and designated Endangered in May 2005. Last assessment based on an updated status report.
