PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. Most of the reports not yet available are status reports for species assessed by COSEWIC prior to May 2002. Other COSEWIC reports not yet available may include those species assessed as Extinct, Data Deficient or Not at Risk. In the meantime, they are available on request from the COSEWIC Secretariat.

COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Quillback Rockfish Sebastes maliger in Canada (2010)

    The Quillback Rockfish (Sebastes maliger) is one of 102 species of rockfish belonging to the genus Sebastes of which 96 are found in the North Pacific. The scientific names are from the Greek sebastos (magnificent) and the Latin malus and gero meaning “mast” and “to bear”, translating into “I bear a mast” referring to the high dorsal fin. Quillback Rockfish are classified as “inshore” rockfish together with yelloweye rockfish, copper rockfish, China rockfish, black rockfish and tiger rockfish and exist primarily over rocky habitats at depths less than 200 m.

  • COSEWIC Assessment Summary and Status Report: Quillback Rockfish Sebastes maliger (2010)

    Assessment Summary – November 2009 Common name Quillback Rockfish Scientific name Sebastes maliger Status Threatened Reason for designationThis species is part of an inshore rockfish complex, with 95% of commercial catch records occurring between 14 and 143m depth. Maximum recorded age is 95 years, age at 50% maturity is 11 years and generation time is over 30 years. No overall estimate of decline is possible, however all survey indices have declined, some by 50–75% since the mid–1980s. Commercial catch per unit effort indices show inconsistent trends and are probably affected by changes in fishing practices. Commercial and recreational fisheries are the principal threats, however, commercial fishing pressure has been reduced as a result of strengthened management regimes established in the mid–1990s, including introduction of closed areas and decrease in commercial harvest quotas. Management measures for recreational fisheries (bag limits) do not restrict catches and the impact of such catches on the species is less understood.

COSEWIC Annual Reports

  • COSEWIC Annual Report - 2010 (2010)

    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”. During the past year, COSEWIC held two Wildlife Species Assessment Meetings and reviewed the status of 79 wildlife species (species, subspecies, populations). During the meeting of November 2009, COSEWIC assessed or reviewed the classification of the status of 28 wildlife species. COSEWIC assessed or reviewed the classification of an additional 51 wildlife species (species, subspecies and populations) during their April 2010 meeting. For species already found on Schedule 1 of SARA, the classification of 32 species was reviewed by COSEWIC and the status of the wildlife species was confirmed to be in the same category (extirpated - no longer found in the wild in Canada but occurring elsewhere, endangered, threatened or of special concern). The wildlife species assessment results for the 2009-2010 reporting period include the following: Extirpated: 6 Endangered: 39 Threatened: 16 Special Concern: 17 Data Deficient: 1 This report transmits to the Minister the status of 46 species newly classified as extirpated, endangered, threatened or of special concern, fulfilling COSEWIC’s obligations under SARA Section 24 and 25. A full detailed summary of the assessment for each species and the reason for the designation can be found in Appendix I of the attached report. Since its inception, COSEWIC has assessed 602 wildlife species in various risk categories, including 262 Endangered, 151 Threatened, 166 Special Concern and 23 Extirpated. In addition, 13 wildlife species have been assessed as Extinct. Also, to date, 46 wildlife species have been identified by COSEWIC as Data Deficient and 166 wildlife species were assessed as Not at Risk. This year has been a particularly productive year for COSEWIC’s Aboriginal Traditional Knowledge (ATK) Subcommittee. In April 2010 COSEWIC approved the Aboriginal Traditional Knowledge Process and Protocol Guidelines, providing clear and agreed principles for the gathering of Aboriginal Traditional Knowledge to carry out COSEWIC functions as required under Section 15(2) of SARA (See Appendix III of the attached report). We are grateful for the rich and enthusiastic contribution made by community elders and experts in helping the ATK Subcommittee prepare the ATK protocols.
