White shark (Carcharodon carcharias) COSEWIC assessment and status report: chapter 12
Technical Summary - Pacific Population
White shark – Pacific population: Grand requin blanc
Extent and Area Information
Threats (actual or imminent threats to populations or habitats)
Commercial fishery bycatch worldwide (no confirmed records from Canada); market for jaws, teeth, and fins; sport angling; coastal habitat modification, pollution.
Rescue Effect (immigration from an outside source)
- COSEWIC: Data Deficient (April 2006);
- CITES Appendix II (October 2004);
- IUCN - Vulnerable
Status and Reasons for Designation
Status: Data deficient
Alpha-numeric code: Not available
Reasons for Designation: The species is globally distributed in sub-tropical and temperate waters, but absent from cold polar waters; hence Atlantic and Pacific populations in Canada are isolated from each other and are considered separate designatable units. This very large apex predator is rare in most parts of its range, but particularly so in Canadian waters, which represent the northern fringe of its distribution. There are only 14 records over 43 years for the Pacific coast of Canada. No abundance trend information is available for Pacific Canadian waters, or for adjacent waters in the United States that would permit a status designation.
