Description

AQUACULTURE SYSTEM
Area of the Invention
The present invention is directed to the field of aquaculture and in particular to a system for accommodating a wide range of live aquatic organisms such as molluscs and fin fish in controlled conditions for breeding, nursery, growing, transporting and storing such organisms. While the invention is described here in terms of its application to acquaculture it is applicable to many areas relating to fisheries and it is to be understood that any reference to aquaculture herein includes fisheries.
Background to the Invention
The aquaculture and fishery industry has a requirement for accommodating live aquatic organisms including for example molluscs, crustaceans, sea urchins, sea cucumbers and finfish in controlled conditions for breeding, nursery, growing, storing and transporting purposes.
Production and storage of these creatures usually involves locating them in tanks of treated water and transferring them to other tanks as they grow, and to clean the water, while further handling and different containers are required for growing the creatures and ultimately transporting them to a destination for sale or the like.
This is clearly an expensive process which requires a lot of equipment and handling. Outline of the Invention
It is an object of the invention to provide improvements over the prior art by providing an accommodation system for aquatic organisms in the aquaculture and fishery industries which requires minimal human input when compared with earlier systems for the maintenance of these organisms.
The invention is an aquaculture apparatus for the accommodation of aquaticorganisms which apparatus includes at least one container unit having an open upper surface and a base and sides and a pipe device located over an aperture in the base such that water which is introduced through the open surface into the container unit will pass through the pipe device when it reaches the height of the pipe device above the base.
It is preferred that the pipe device be located adjacent one side of the base of the container unit.
It is also preferred that the aquaculture apparatus include a plurality of container units.
It is further preferred that these units be stacked one above the other and that they be oriented such that inflow of water from a container unit above any unit occurs at an opposing side of the container unit from its pipe device.
It is preferred that the aquaculture apparatus be able to have any number of and arrangement of container units. For example container units could form a single row or a plurality of rows and they can be stacked to any preferred height.
It is however preferred that a completed stack be provided with a water supply at each uppermost unit of a stack which passes sequentially through the stack to a collector sump to receive water from a lowermost unit.
In order that the invention may be more readily understood we will describe by way of non limiting example specific embodiments of the invention with reference to the accompanying drawings.

Description of an embodiment of the invention
The aquaculture apparatus 10 of the invention provides for the accommodation of aquatic organisms. Accommodation is provided in container units 20 each having an open upper surface 21 and a base 22 and sides 23 and a pipe device 25 located over an aperture in the base 22 such that water which is introduced through the open surface into the container unit will pass through the pipe device when it reaches the height of the pipe device above the base.
The size of the container unit, and the height of the pipe device, can be dimensioned to accommodate a particular aquatic organism. Water at the required flow-through rate is introduced into the top of the unit and the height of the pipe device determines the height of the water in the unit.
One such unit 20 is stacked onto an identical unit 20 that has been rotated horizontally through 180 degrees. This process is repeated as many times as required to create a stack of units, each discharging its water output by gravity flow through the pipe device into the one below.
The container unit 20 is preferably made of non-corrosive, food-grade material such as a plastic suited for its manufacture through appropriate techniques.
The aquaculture apparatus may consist of single units, or may be produced as a container with a number of container units in a single row, or as a tray 40 with units forming a number of rows. Five such rows being shown in Figure 5. The completed stack is provided with a water supply to each uppermost unit through water distribution points 32 , and a collector sump 50 to receive water from each lowermost unit.
This simple novel idea results in the overflow from each unit's standpipe filling the unit below it, and so forth down the stack.
The units can be built into a stack as high as is needed and is practical, and placed in rows as long as required. All that has to be provided to get the system working is a water supply to each uppermost unit, and a collector sump to receive water from each lowermost unit.
The units can be manufactured to suit the particular application, in terms of length, width, and height of each container unit , and the height of the standpipe above the unit floor (to set the depth of water within the unit).
From the basic unit, several additional features are available, depending upon requirements.
Figure 2 shows a lid 30 arrangement with a simple water distribution device 35 for the uppermost unit and water distribution points 32 to each upper unit are shown. Also shown in Figure 4 is a collector sump 50 to receive water from the lowermost unit during operation and from the stack at draining times. Figure 4 also shows tray supports 55.
While the simplest form of this invention comprises stackable container units, thereby obviating the necessity for any other supporting structure, the same system can be operated if the accommodation units are held on shelves or by some other means so that they are aligned one under the other, each being horizontally rotated through 180 degrees with reference to the one below it as shown in Figure 3 which shows schematically how a five-level stack fitted with feeding tubes is assembled.
Figure 5 shows an assembled stack five trays high where three trays have been removed and functionality is retained by placing lids to deliver water to the lower levels.
In the embodiment of the invention shown the water flow system may be direct flow- through to waste. Alternatively it may be preferred to utilise recirculated water collected from the lowest unit and pumped to the top again.
In the simplest embodiment of the invention previously mentioned the pipe devices 26 are of a truncated cone type shape in order that they may nest when not in use and otherwise stack when oriented for use. An example of this arrangement is shown in Figure 6.
Feeding of animals in all the units within a stack can be easily accomplished by either of two mechanisms.
Firstly, the units can be manufactured with vertical delivery tubes to provide direct conduit from the top of the stack to each of the units below. Each level of the stack is separately identified and manufactured complete with the required number of delivery tubes.
Secondly, access to each unit can be provided through port-holes 60 set above the water level of each unit. A drain plug 27 can be provided at or near the base of each container unit.
While the simplest form of this invention comprises stackable containers, thereby obviating the necessity for any other supporting structure, the same system can be operated in any combination of supports and arrangements for example the container units can be held on shelves or by some other means so that they are aligned one under the other, each being horizontally rotated through 180 degrees with reference to the one below it.
In any of its described embodiments the invention described here provides a unique means for carrying out an aquaculture system using a simple layered and effectively self-watering means and while we have described here specific embodiments of the invention it is to be understood that variations and modifications in these can be made without departing from the spirit and scope of the invention.
