Abstract: An apparatus (1) for storing aquatic animals comprises a tank (3) for receipt of the aquatic animals, and an arrangement (9) to create a foam environment (13) in the interior of the tank (3) such that at least a majority of the aquatic animals when stored in the tank (3) are submerged in foam. The arrangement to create a foam environment may be configured to deliver a synthetic foam to the interior of the tank (3), or may be configured to generate the foam, preferably from the natural proteins of the aquatic animals. A fluid recirculation arrangement may recirculate fluid to generate the foam.
