Abstract
Abstract An aquaculture rearing system for improving space utilization and yield is disclosed in which clustered, vertical rearing tanks are provided with individual stacked habitats in the form of baskets attached to a strongback member which houses a removable feeding rod, in which the baskets are quickly detachable through the use of interlocking detents and in which nestable baskets are utilized for different sized animals. Progressive space increments to match growth are provided by two different size baskets and removable dividers. Overflow water is skimmed by a skimmer which surrounds the entire top of each tank to prevent bacteriologic contamination of the water within the tank. The staggered modular mounting produces a tripod-like stability even though each tank has a single leg, and provides visibility and density. An overhead materials handling system is used in which the animals are protected by a fog to prevent gill malfunction. Animal health and growth is monitored by an electronic scanning device which records the amount of food consumed by each animal involved over a period of time and compares performance with predetermined standards.

Claim 3
Dependent Claim
183 words
Apparatus for the rearing of aquatic animals comprising: a tank including a vertically oriented vessel, a tapered base member at one end of said vessel, said base member having an outlet at the tapered end, and a skimmer surrounding the top of said vessel, said vessel being pressed fit into said base member, said base member further including a first support member extending downwardly from the tapered end and a second support member extending downwardly from the non-tapered upper end, both support members terminating in the same horizontal plane beneath said tapered end, said base member also including a rib between first and second support members, and a mounting base including a flat plate and an upwardly extending U-shaped member, said U-shaped member having a configuration adapted to receive the bottom edge of said rib; and a single vertically stacked arrangement of animal rearing compartments per vessel, each compartment being in the form of a basket of a diameter less than the inside diameter of said vessel, said stack arrangement including a strongback member for removeably mounting said basket to said strongback member.
Claim 4
Dependent Claim
183 words
Apparatus for the rearing of aquatic animals comprising: a tank including a vertically oriented vessel, a tapered base member at one end of said vessel, said base member having an outlet at the tapered end, and a skimmer surrounding the top of said vessel, said vessel being pressed fit into said base member, said base member further including a first support member extending downwardly from the tapered end and a second support member extending downwardly from the non-tapered upper end, both support members terminating in the same horizontal plane beneath said tapered end, said base member also including a rib between first and second support members, and a mounting base including a flat plate and an upwardly extending U-shaped member, said U-shaped member having a configuration adapted to receive the bottom edge of said rib; and a single vertically stacked arrangement of animal rearing compartments per vessel, each compartment being in the form of a basket of a diameter less than the inside diameter of said vessel, said stack arrangement including a strongback member for removeably mounting said basket to said strongback member.
Claim 5
Dependent Claim
127 words
Apparatus for the rearing of aquatic animals comprising: a tank including a vertically oriented vessel, a tapered base member at one end of said vessel, said base member having an outlet at the tapered end, a skimmer surrounding the top of said vessel and an annular gasket between said base member and said vessel, said gasket having an inward flange at its base and having annular inwardly projecting ribs on the vertically rising portion of said gasket; and a single vertically stacked arrangement of animal rearing compartments per vessel, each compartment being in the form of a basket of a diameter less than the inside diameter of said vessel, said stacked arrangement including a strongback member and means for removably mounting said baskets to said strongback member.
