An aquaculture habitat is described for the rearing of post larval crustacia in which a cellular honeycomb structure, preferably of opposed cones, provides compartments for the animals and serves as the domicile core. Individual animals are inserted into the core compartments and the core is sealed with a screen or a mesh on either side of the core. The screen or mesh is of a size such that water and food may pass through but which restrains the animals. Cores with screens in place are vertically oriented and horizontally stacked on a false bottom within a tank of water. The tank is provided with food distribution means adjacent the false bottom, and air lift circulation means beneath the food distribution means which, due to the upward rise of the expanding air bubbles, moves the food and freshly filtered and aerated water to the vicinity of the habitats. Animal feeding is accomplished by food penetration through the screen or by the animal plucking the food from the adjacent water by reaching through the screen. Moreover, habitat cleaning is accomplished by the animal in pushing out unwanted debris from the compartment through the screen.

A method of providing food, air, and water to animal rearing compartments comprising the steps of: providing in a tank of water compartments having openings and mesh means covering said openings; positioning food distribution means beneath said compartments in said tank; and providing air lift circulation means beneath said food distribution means, such that bubbles formed by said air lift circulation means carry food from the food distribution means into the vicinity of said mesh means.
