Abstract

L'invention concerne un procédé de conservation d'animaux aquatiques tels que des poissons, crustacés, coquillages â l'état vivant sans immersion. Ce procédé de conservation est réalisé en plusieurs étapes: a) abaissement de la pression absolue autour de l'animal jusqu'à une valeur comprise entre 4,5 et 8 millibars b) retour à la pression atmosphérique autour de l'animal; c) disposition des animaux dais .un emballage comportant une ouverture et, d) recouvrement de cette ouverture au moyen d'une membrane d'élastomère silicone l'ensemble étant maintenu ultérieurement à 0°C. Les animaux aquatiques sont conservés à l'état vivant pendant au moins quinze jours, et peuvent reprendre ensuite une activité normale. The invention relates to a method of conservation of aquatic animals such as fish, crustaceans, shellfish in a living state without immersion. This preservation process is carried out in several stages: a) lowering the pressure absolute around the animal up to a value between 4.5 and 8 millibars b) return to atmospheric pressure around the animal; vs) arrangement of the canopy animals. a package comprising an opening and, d) covering of this opening using a silicone elastomer membrane the whole being subsequently maintained at 0 ° C. The aquatic animals are kept alive for at least fifteen days, and can resume then normal activity.
