Preface

The competent minister for the Copper Redhorse under the Species at Risk Act (SARA) is the minister of Fisheries and Oceans Canada (DFO). Because this species makes use of the Vianney-Legendre fish ladder, the minister responsible for the Parks Canada Agency (Parks Canada) is the competent minister for individuals located in the ladder. Section 37 of SARA requires the competent minister to prepare recovery strategies for listed extirpated, endangered or threatened species. The Copper Redhorse was listed as endangered under SARA in December 2007. Fisheries and Oceans Canada – Quebec Region led the development of this recovery strategy in close collaboration with the Copper Redhorse Recovery Team. This strategy meets SARA requirements in terms of content and process (Sections 39-41).

The successful recovery of the Copper Redhorse will depend on the commitment and cooperation of the many concerned parties who will participate in the implementation of the recommendations put forward in this strategy. Success will not depend solely on Fisheries and Oceans Canada or any one jurisdiction. In the spirit of the Accord for the Protection of Species at Risk, the ministers of Fisheries and Oceans Canada and Parks Canada invite all Canadians to join with Fisheries and Oceans Canada and Parks Canada in supporting and implementing the strategy, for the good of the species and of Canadian society as a whole. Fisheries and Oceans Canada and Parks Canada are committed to providing support for the implementation of the strategy, subject to the availability of resources and the various priorities regarding the conservation of species at risk. Other jurisdictions and agencies will participate in implementing the strategy according to their respective policies, allocated resources, priorities, and budgetary constraints.

The recovery goal, objectives and approaches identified in this document were developed based on the best available information and are subject to modification as new data become available. The ministers will issue a progress assessment report within five years.

One or several action plans presenting detailed descriptions of specific recovery measures required to ensure the conservation of the species will be added to the present strategy. Insofar as possible, the ministers will implement mechanisms to see that all Canadians directly interested in or affected by these measures will be consulted.

In 1987, The Committee on the Status of Endangered Wildlife in Canada (COSEWIC), initially designated the Copper Redhorse (Moxostoma hubbsi) as threatened; in November 2004 COSEWIC changed the designation to endangered. In December 2007, this species was listed as endangered in Schedule I of the Species at Risk Act. In 1999, it was designated threatened under the Quebec Act Respecting Threatened or Vulnerable Species. The present recovery strategy was developed following three five-year intervention plans (1995, 1999, 2004) developed and implemented by the Ministère des ressources naturelles et de la faune (MRNF) and its partners.

The above-mentioned intervention plans resulted in the creation of an important partnership network bringing together various government departments and levels, non-governmental agencies, and Quebec, Canadian and American universities.

Acknowledgements

They are also grateful to all the members of the Recovery Team for their conscientious work in providing information, counsel and advice during the development of the recovery strategy. Thanks also go to Gilles Fortin of DFO and Lucie Veilleux of MRNF for their help with mapping.

And finally, DFO and Parks Canada Agency would like to acknowledge the critical contribution of all those who have offered comments on this document.

Executive Summary

The Copper Redhorse (Moxostoma hubbsi) is the only fish whose distribution is exclusively restricted to Quebec. This range is restricted even further to the St. Lawrence River and some of its tributaries. At the present time, the Richelieu River is the only body of water in which reproductive activity has been confirmed.

The Copper Redhorse population is in decline. Several threats to the recovery of the species have been identified: habitat degradation (sedimentation, degradation of riparian environment, eutrophication, organic pollution), construction of dams, contaminants, exotic or introduced species, recreational activities, commercial fishery, and low water levels. Certain biological characteristics of the Copper Redhorse such as the late age of sexual maturity, late spawning activities and specialized diet contribute to its vulnerability.

In November 2004, the Copper Redhorse population was designated endangered by the Committee on the Status of Endangered Wildlife in Canada. In December 2007, the population was listed as endangered in Schedule I of the Species at Risk Act. In 1999, it was designated threatened under the Quebec Act Respecting Threatened or Vulnerable Species.

The goal of this recovery strategy is to attain a population of 4,000 mature individuals over a period of 20 years. Five objectives have been identified to reach this goal:

The Copper Redhorse is the focus of increasing interest on the part of the general public and different organizations. This recovery strategy aims to coordinate the various actions that must be taken to complete the work already accomplished to prevent the disappearance of this species which is endemic to Canada. It also includes the identification of the critical habitat of the species: grass bed inhabited by adult Copper Redhorse in the St. Lawrence River, the littoral area along the Richelieu River used by juveniles and for migration, and the rapids of the Chambly and Saint-Ours dams, used for spawning.

Recovery Feasibility

Recovery of the Copper Redhorse is considered possible because it meets the four criteria of technical and biological recovery feasibility.
