Recovery Strategies

Recovery Strategy for the Copper Redhorse (Moxostoma hubbsi) in Canada

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.
