Abstract
The Copper Redhorse, Moxostoma hubbsi, a threatened fish species endem ic to southwestern Quebec, has been reproduced artificially. Intramusc ular injection of Carp pituitary extract (CPE), dry fertilization, inc ubation at 20-degrees-C and rearing with a dry diet yielded good resul ts. Small Copper Redhorse ate any mollusks that were offered to them i ncluding the Zebra Mussel (Dreissena polymorpha). Consequently, fish r aised under artificial conditions could adapt rapidly if stocked in a natural environment.
