Shortjaw cisco COSEWIC assessment and status report: chapter 6
Protection
Shortjaw ciscoes were listed as Threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 1987 (Houston 1988). In general, no specific protection has been provided for the shortjaw cisco in Canada, except for general protection afforded through the Fisheries Act. However, all species of deepwater ciscoes (chubs) in Lake Superior are managed by quota as a group. And, while exploitation in Lake Superior is not currently a threat with the absence of a commercial chub fishery, the quotas could protect the species if the fishery resumes. The lake whitefish fishery of Lake Nipigon takes some shortjaw ciscoes as by-catch, but this by-catch is not regulated by quota. Other populations in Canada are not specifically protected, and are not subject to fishery exploitation, either.
