A. Branchaud et Ad. Gendron, ARTIFICIAL SPAWNING AND REARING OF THE COPPER REDHORSE, MOXOSTOMA-HUBBSI (TELEOSTEI, CATOSTOMIDAE), Canadian field-naturalist, 107(3), 1993, pp. 279-282
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.
