CA 2374254

A fish cage having one or more air-tight buoyancy rings (1) being entirely or partially hollow, with water valves (20) for inlet and outlet of water, and air valves (3) for injection and outlet of air, and preferably with closing shot plates (2) in the buoyancy ring (1). The novel feature according to the invention is that at least one or more of the air valves (3), and preferably also the air valves (20) are arranged inside of the buoyancy ring (1) so that the air valves (3) and water valves (20) are protected from external mechanical influence.

La présente invention concerne un parc piscicole comportant un ou plusieurs boudins de flottaison étanches (1) qui sont complètement ou partiellement creux, des vannes (20) d'admission et d'évacuation de l'eau, et des vannes (3) d'injection et d'évacuation de l'air, et de préférence des plaques de fermeture (2) prévues dans le boudin de flottaison (1). La nouveauté de l'invention réside dans le fait qu'au moins une des vannes d'air (3), et de préférence également les vannes d'eau (20) sont placées à l'intérieur du boudin de flottaison (1) afin que les vannes d'air (3) et les vannes d'eau (20) soient protégées de toute influence mécanique extérieure.
