DOWNLOAD EBOOKIn April 1987, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) designated Shortjaw Cisco (Coregonus zenithicus) as Threatened. The status was re-examined and confirmed in May 2003. These species must be re-assessed under the new criteria of the Act before they can be added to Schedule 1, and thus receive legal protection, or be removed from the list. Typically, products of a pre-COSEWIC assessment are Canadian Science Advisory Secretariat (CSAS) Research Documents and Proceedings summarizing key points of discussion at the meeting. In the case of Shortjaw Cisco, however, a second objective of the meeting (in addition to the peer review) was to provide Science Advice on the taxonomic validity of Shortjaw Cisco outside of the Laurentian Great Lakes and, if deemed to be valid, the designatable units (DUs) that should be recognized within Canada. These intertwined issues have been the subject of ongoing debate in the scientific literature. The resolution of these issues will aid in the accuracy of the COSEWIC assessment.--Document.

DOWNLOAD EBOOKShortjaw Cisco (Coregonus zenithicus) were originally described in Lake Nipigon in the 1920s, and have been consistently identified in the limited number of subsequent cisco surveys of the lake. With the exception of ecomorphological and genetic research conducted on the cisco community of Lake Nipigon in the late 1990s, little attention has been focused on any cisco species from this lake. Fisheries and Oceans Canada (DFO) Science was charged with conducting a pre-COSEWIC assessment for Shortjaw Cisco, and this manuscript assesses the current: 1) life history characteristics; 2) the characteristics or elements of the species habitat; 3) threats to the species; and 4) population trends with a limited time series for Shortjaw Cisco from Lake Nipigon.--Document.
