ABSTRACT:
A vertical housing and feeding structure for raising mariculture and other underwater animals. Tiers of feeding tubes, each of a successively longer length, form a backbone structure to which cages may be selectively connected. Each cage is connected along a vertical front face of the backbone structure so that one of the feeding tubes terminates at a point accessible from within the cage. A feed opening just above this termination point directs food material dropped through the feeding tube to either fall within the cage or be accessible from therewithin so that it may be consumed by the caged animal. All of the feeding tubes of each tier have a top open end that is positioned near the surface of the water to facilitate the controlled delivery of food to each individual cage. Two sets of backbone structure may be joined back-to-back so that cages may be connected to both sides of the structure, thereby doubling the cage capacity of the system. The capacity of the backbone structure may also be augmented by increasing the width of the tiers of feeding tubes or by adding additional tiers of feeding tubes to the back of each backbone structure, each additional tier being of a successively longer length. Either method thus increases the frontal area of the backbone structure and provides additional frontal space to which additional cages may be attached. Inspection of the cages is facilitated by hoisting the entire backbone structure, including the cages attached thereto, out of the water. The walls of the cages are screened with a sufficiently large mesh to allow oxygenated water to freely circulate therethrough and to further allow fecal material and uneaten food to fall out of the cage without accummulation.
