The spaces in the Marinarium

A dive into the Breton waters during which the visitor will discover the local marine fauna and flora.

Immersion in the marine world

This space is organised around a globe in continuous rotation on an axis. Five terminals with metal hoods are distributed around this globe bearing information such as the importance of water, ocean life output, etc.

Besides diving into the oceans, the visitor is also immersed in the scientific context of the station, with the prelude "Know, Understand, Manage" whose objective is to present the missions of the marine station.

Plankton

This space introduces the notions of primary production, the food chain and allows the observation of phytoplankton and zooplankton through binoculars, a microscope and the presentation of a film. Backlit photographs illustrating the diversity of microorganisms are also displayed. Thanks to a glazed opening, the phytoplankton production room is visible to the public.

Coastal ecology

In this part, three aquariums introduce the notion of coastal staging in the tour circuit with the aquarium:

  • The rocky shores puddle
  • Pouldohan herbarium
  • Sandy coasts

These aquariums face a wall that displays a long frieze showing the distribution of organisms on the coast depending on the bathymetry and the substrate. The Littoral documentary, in which the adaptation of organisms according to the tide is discussed, can be viewed at the end of this space.

Manage the sea

This space is arranged in several sections. The first section presents the basking shark as a stuffed animal. The biological cycles of cod, monkfish and tuna are explained next on a set of panels. A film about resource exploitation completes this section. An aquarium open on two sides allows viewing of organisms of commercial interest such as the dogfish, sole, lobster, sea urchins...

Glénan, an atoll in the Atlantic

Five aquariums and a tactile basin compose this space.
Five aquariums and a tactile basin compose this space. The aquariums are populated with organisms according to the different branches. The visitor can observe cnidarians and sponges in a first aquarium and then crustaceans in the second aquarium. Echinoderms, molluscs, tunicates and annelids are grouped in a third aquarium. The wall of the fourth aquarium houses small fish belonging in particular to the wrasses family. The Great Basin, which represents a rocky bottom of the Glénan Archipelago, allows the visitor to contemplate not only bony fishes of open water, but also species that populate the rocky substrates and those that live in sandy substrates.
