COSEWIC Status Reports

COSEWIC Assessments

  • COSEWIC Assessment - Roundnose Grenadier (2009)

    Coryphaenoides rupestris, commonly known as the Roundnose Grenadier (occasionally, rock grenadier) in English or Grenadier de roche in French, belongs to the family Macrouridae or rattails. It is distinguished from other grenadiers in the North Atlantic by its soft, rounded snout and relatively short, compressed head.

Response Statements

  • Response Statement - Roundnose Grenadier (2009)

    Survey data indices of adult numbers show declines of 98% from 1978 to 1994 with a further decline from 1995 to 2003.  Although much of the population lives at depths greater than those surveyed, adding uncertainty to the assessment, this constitutes the best available information to assess species status. The species is long-lived (60 yr) and matures late (around 10 yr) which makes it susceptible to human-caused mortality. Commercial catches were high in the 1960s and 1970s but have since declined, although harvest still occurs.

Consultation Documents

  • Roundnose Grenadier Consultations on listing under the Species at Risk Act (2015)

    Canada’s Species at Risk Act (SARA) provides legal protection for wildlife species at risk to conserve biological diversity.  It also acknowledges that all Canadians have a role to play in the conservation of wildlife species. Before deciding whether Roundnose Grenadier (Coryphaenoides rupestris) will be added to the List of Wildlife Species at Risk, we would like to hear your opinion, comments, and suggestions regarding the possible ecological, cultural, and economic impacts of listing or not listing this species under SARA.
