Copper Redhorse critical habitat in Quebec

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.

This layer represents the Copper Redhorse critical habitat defined by the analysis of available knowledge and a scientific advice.

Purpose

The Copper Redhorse population is in decline due to several threats like habitat degradation, construction of dams, contaminants, exotic or introduced species, recreational activities, commercial fishery, and low water levels. Furthermore, certain biological characteristics of the Copper Redhorse contribute to its vulnerability. The Copper Redhorse population was officialy listed as endangered in Schedule I of the Species at Risk Act in December 2007.

Additional Information

Critical habitat for the Copper Redhorse has been identified to the extent possible, based on the best available information. Two workshops held in 2009 and 2010 by Fisheries and Oceans Canada and the Ministère des Ressources Naturelles et de la Faune du Québec, allowed to review the information and take note of the new data to identify habitat use by the Copper Redhorse in the St. Lawrence and Richelieu rivers and later in the Rivière des Prairies and Rivière des Milles Îles.

Adult feeding habitat in the St. Lawrence River between Lake Saint-Louis and Lake Saint-Pierre, was identified using modeling based on the telemetric monitoring of habitat use and on twelve habitat variables (for example: depth, current velocity, vegetation density). Also, recent telemetry and historic data confirmed the use of the lower stretches of the Rivière des Prairies and Rivière des Mille Îles. Critical adult feeding habitat is consequently identified as habitat in the fluvial reach between Montreal and Sorel presenting favorable characteristics for the copper redhorse, used in the model.
