COSEWIC Status Reports

  • COSEWIC assessment and status report on the White Hake Urophycis tenuis in Canada (2014)

    White Hake, Urophycis tenuis (Mitchill, 1815), is a member of the Family Phycidae, and is one of many cod-like (gadiform) fishes found on the east coast of Canada. Common names include White Hake, Ling, and merluche blanche (Fr). The combination of a single small barbel at the tip of the lower jaw, two dorsal fins, and elongated pelvic fins identifies fish from the western Atlantic in waters off Canada to the genus Urophycis. White Hake and Red Hake (Urophysis chuss) are distinguished by the number of lateral line scales and the number of gill rakers on the upper arm of the first gill arch.

Response Statements

  • Response Statement – White Hake, Atlantic and Northern Gulf St. Lawrence population (2015)

    Adults in this population are estimated to have declined by approximately 70% over the past three generations. Most of this decline occurred before the mid-1990s. The population has remained fairly stable since then, and there has been little overall trend in area of occupancy. Restrictions on fisheries since the mid to late 1990s over most of their range may be responsible for stabilizing their numbers.

COSEWIC Annual Reports

  • COSEWIC Annual Report - 2013-2014 (2014)

    Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to "assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species". COSEWIC held two Wildlife Species Assessment Meetings in this reporting year (October, 2013 to September, 2014) from November 24 to November 29, 2013 and from April 27 to May 2, 2014. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 56 wildlife species. The wildlife species assessment results for the 2012-2013 reporting period include the following: Extinct: 0 Extirpated: 0 Endangered: 23 Threatened: 12 Special Concern: 20 Data Deficient: 0 Not at Risk: 1 Total: 56 Of the 56 wildlife species examined, COSEWIC reviewed the classification of 40 that had been previously assessed. The review of classification for 25 of those wildlife species resulted in a confirmation of the same status as the previous assessment.
