Aquarium de Lyon, Public aquarium in La Mulatière, France.

The Aquarium de Lyon in La Mulatière holds 39 tanks with over 1,000,000 litres of water, showing 3,000 aquatic animals of 300 species. Its largest tank, the Fosse aux Requins, contains a false shipwreck made of polyurethane resin and has glass 23 cm thick to resist water pressure. The tanks are arranged in four sectors: La Confluence, La Balade tropicale, Les récifs du monde and Les curiosités marines.

The Aquarium de Lyon was created by Maurice Chichportiche, who also owned the Aquarium d'Intra Muros in Saint-Malo, and opened in October 2002 after two years of construction. It now belongs to the Spanish group Aspro-Ocio, which also owns the Aqualand parks.

The aquarium is divided into four named sectors: La Confluence for temperate freshwater fish, La Balade tropicale for tropical freshwater fish, Les récifs du monde for reef species, and Les curiosités marines. The largest tank, the Fosse aux requins, holds a false shipwreck made of polyurethane resin, chosen because iron would rust and the rust is toxic to fish.

The aquarium stands in La Mulatière, at the confluence of the Rhône and Saône, south of central Lyon; allow time to reach it from the city centre. Inside, the route passes through four sectors: La Confluence, La Balade tropicale, Les récifs du monde and Les curiosités marines. The largest tank, the Fosse aux requins, is viewed through glass 23 cm thick.

The largest tank, the Fosse aux requins, holds a false shipwreck made of polyurethane resin rather than iron, which would rust and poison the fish. Its viewing glass is 23 cm thick at the base to withstand the water pressure.
