Aquarium du Québec (English: Aquarium of Quebec) is a public aquarium located in the former city of Sainte-Foy in Quebec City, Quebec, Canada. The facility is home to more than 10,000 animals representing more than 300 species. It is operated by Société des établissements de plein air du Québec (Sépaq), and is a member of the Canadian Association of Zoos and Aquariums (CAZA).
The origin of the Aquarium du Québec dates back to 1953, when ichthyologist Dr. Vadim D. Vladykov convinced Dr. Arthur Labrie, Deputy Minister of Ministry of Fisheries, to obtain a site near the Quebec Bridge that belonged to the Canadian National Railway. The provincial government acquired the land in 1954, and work to construct the buildings began in 1955.
In 1956, the Biological Centre of Quebec opened, and included laboratories occupied by research teams in marine biology and fisheries, a rotunda, and two series of aquariums. Soon, a research wing was added to house laboratories for research on species with commercial potential, such as salmon, eel, and lobster, and to gather all documents in the library of the Ministry of Fisheries. 230,000 gallons of freshwater were supplied by tanker from Lake Saint-Charles and drawn directly from the St. Lawrence River. The 320,000 gallons of saltwater were brought in from as far away as Rimouski (Pointe-au-Père).
In 1959, after the completion of reception areas and a restaurant, the aquarium opened to the public as the Organic Centre. The Organic Centre's educational mission was provided in collaboration with the Linnean Society of Quebec that establishes a program for children, a first for a museum in Quebec. The 150,000 visitors that were welcomed in the first year caused additional investment for the site that included outdoor pools for seals additional aquariums.
In 1971, researchers at the Biological Centre eventually moved to the new Science Complex of Quebec. To reflect the fact that the aquarium had evolved into a public education facility (although research work in collaboration with universities continues), it changed its name to the Aquarium du Québec.
