"The copper redhorse is the only fish living exclusively in Quebec. Weighing more than 5 kg and with a length generally greater than 50 cm, it is the largest of Quebec’s redhorses. It also lives the longest, reaching thirty years of age. This copper tinted fish with large scales has robust teeth, particularly well adapted to crush the shells of its preys. Copper redhorse population size estimates remain uncertain, numbering them at the most a few hundred individuals."
