In year 2000 we first visited the Noumea Aquarium, and were delighted by the natural lighting, the selection of native marine species, and that the water in the aquarium is provided by a flow through of clean seawater from the nearby Baie des Citrons. In year 2005 the aquarium was closed for two years for the construction of a completely new facility. All of the wonders of the original aquarium have been retained, and all areas have been expanded and modernized. The original founders, Dr Rene’ Catala and his wife Ida were prominent marine biologists for their discoveries in coral reef ecology, especially the fluorescence of certain corals. More recently, the aquarium has developed techniques for captive breeding of the Chambered nautilus. Two juvenile Chambered nautilus were on display for us to see. Educational displays accompany many of the exhibits, providing scientific information and education.
