Brief Description of the Drawings
Embodiments of the present invention will now be described below with reference to the following drawings in which:
Figure 1 is a schematic representation of a first embodiment of a live aquatic animal transport system; and,
Figure 2 is a schematic representation of a second embodiment of a live aquatic animal transport system.
Detailed Description of the Preferred Embodiments
In broad terms, an embodiment of a live aquatic animal transport system in accordance the present invention comprises container that is capable of holding a volume of water and one or more live aquatic animals and into which oxygen is delivered at a rate required to maintain a dissolved oxygen concentration in the water within a selectable range. The system may therefore comprise a supply of oxygen such as an oxygen tank, or an oxygen selective membrane, each of which is capable of delivering oxygen to water in the container, and a control system which controls the oxygen supply to deliver oxygen at the required rate. One or more dissolved oxygen sensors provide signals representative of dissolved oxygen concentration in the water which is then used to control the supply of oxygen. A carbon dioxide stripper is also incorporated in the system to strip carbon dioxide from water held within the container. A further sensor is incorporated to provide a signal indicative of the level of carbon dioxide in the water. The sensor may for example be a pH probe. In this regard, where there is a known relationship between water pH and dissolved carbon dioxide a measure of pH may be used to provide an indication of the level of dissolved carbon dioxide.
Water from the container together with a stream of a gas such as air is passed through the CO2 stripper. CO2 which is removed by the CO2 stripper from the water flow is subsequently swept from the stripper by the steam of gas.
Referring specifically to Figure 1, a first embodiment of a live aquatic animal transport system 10 comprises a container 12 with a first compartment 14 capable of holding a volume of water and one or more live aquatic animals (e.g. fish) 16. An oxygen supply system 17 in this embodiment comprises: an oxygen vessel or cylinder 18; a hose 20; and, an oxygen diffuser 22 connected by the hose 20 to the cylinder 18. The oxygen vessel or cylinder 18 contains a volume of a gas comprising or consisting of oxygen. Thus in one example cylinder 18 may contain compressed oxygen gas. The oxygen supply system 17 is capable of delivering oxygen to water held within compartment 14. A control system 24 controls the oxygen supply system 17 and in particular the supply of oxygen from oxygen cylinder 18 into the water held within the first compartment 14 to maintain a dissolved oxygen concentration in the water within a selectable range. The oxygen flow rate required to achieve a particular dissolved oxygen concentration range may vary depending on the type of aquatic animals 16, the volume of water within container 12, density of aquatic animals within the water, and water temperature. System 10 also comprises a carbon dioxide stripper 26 which is capable of stripping carbon dioxide from water held in compartment 14. Water pump 28 pumps water held within compartment 14 through the carbon dioxide stripper 26. This water is then returned to compartment 14. An air pump 30 is also provided to provide air which passes through the carbon dioxide stripper 26 and sweeps carbon dioxide stripped from the water from the stripper 26 to a location outside of container 12.
In the present embodiment, container 12 is configured and arranged to enable transport of live aquatic animals 16 via aircraft. However, as will be explained in greater detail below, in alternate embodiments, different forms of container 12 may be used for road transport of other types of transport.
Looking at system 10 in greater detail, container 12 comprises the first compartment 14 and a second compartment 32. Compartments 14 and 32 are separated by a removable and sealable partition or inner lid 34. Container 12 is configured so that when inner lid 34 is properly seated in container 12, a liquid tight seal is formed preventing escape of any water from the first compartment 14. Various sealed openings are formed within inner lid 34 to enable passage of conduits and hoses such as hose 20 as well as air inlet hose 36 and carbon dioxide venting hose 38.
Second compartment 32 is formed between inner lid 34 and an outer detachable lid 40. Outer lid 40 is provided with one or more ventilation openings 42. In this particular embodiment oxygen cylinder 18 is housed within second compartment 32 between inner and outer lids 34 and 40. One or more brackets or clamps (not shown) may be used to fix cylinder 18 to or between walls of container 12.
Control system 24 includes a microcontroller or processor, and a number of sensors including, but not limited to, a dissolved oxygen concentration sensor 44 a dissolved carbon dioxide level sensor 46, air pressure sensor 48 for providing signals indicative of air pressure within stripper 26, and water pressure sensor 50 for providing signals indicative of water pressure within stripper 26. A water temperature sensor 52 may also be provided. Each of the sensors 44, 46, 48, 50 and 52 provides signals to the processor of the control system 24.
Carbon dioxide sensor 46 may be a sensor which directly measures or provides a signal indicative of the level of dissolved carbon dioxide within the water, or alternately may be in the form of a pH sensor. In this regard, testing has indicated a relationship between pH and dissolved carbon dioxide concentration. Accordingly by knowing the relationship, a measure of pH can provide a corresponding measure of carbon dioxide concentration.
Control system 24 is capable of controlling water quality and characteristics within compartment 14 by appropriate control of the rate of delivery of the gas from cylinder 18 to water within compartment 14. In addition, as explained further below, control system 24 may also operate to control the level of dissolved carbon dioxide by exerting appropriate control over water pump 28 and air pump 30 pursuant to air pressure and water pressure signals from sensors 48 and 50. A valve such as an oxygen solenoid valve 54 controls release of oxygen from cylinder 18 through conduit 20 to the diffuser 22. Valve 54 is coupled with and controlled by control system 24. Depending on the preset desired range of dissolved oxygen concentration in the water, and readings from dissolved oxygen concentration sensor 44, control system 24 will operate valve 54 to regulate delivery of oxygen from cylinder 18 to the water within compartment 14. In the event that system 10 is used for the airtransport of aquatic animals, for safety reasons the solenoid valve 54 and control system 24 should be isolated from the oxygen cylinder 18 by being disposed underwater in the compartment 14.
Carbon dioxide stripper 26 in this embodiment comprises a membrane which is impermeable to water but highly selective for carbon dioxide. The membrane is disposed within a housing 56 of the stripper 26. Housing 56 also includes a water inlet 58, water outlet 60, air inlet 62, and air outlet 64. Water pump 28 is coupled to water inlet 58 via a pre-filter 66 and conduit 68. Air pump 30 is coupled to air inlet 62 via conduit 69, while air outlet 64 is vented to atmosphere, i.e. a location outside container 12, via the venting hose 38. Fresh air is drawn in from the ambient atmosphere by air pump 30 via air hose 36 and subsequently pumped to the stripper 26 via conduit 69.
Water pump 28 circulates water from compartment 14 through the stripper 26 so that the water returns via outlet 60 to the first compartment 14. As water flows through the stripper 26, carbon dioxide is released through the membrane. The released carbon dioxide is swept from the stripper 26 by the flow of air produced by operation of the pump 30.
The processor in the control system 24 receives signals indicative of concentration or level of dissolved carbon dioxide from sensor 46. This information may be used by the processor to also control water pump 28 and air pump 30 to regulate water and air pressure within C02 stripper 26 to maintain concentration of dissolved carbon dioxide below a threshold level. In particular, the processor may operate to control water pump 28 and air pump 30 to ensure that air pressure within carbon dioxide stripper 26 does not exceed water pressure within the carbon dioxide stripper.
It is further envisaged that the control system 24 and in particular the processor will monitor and log the sensed conditions/characteristics to enable subsequent download and analysis of data. Any type of conventional connection port such as a USB, or Ethernet port may be provided to allow connection of the processor of control system 24 with a PC to facilitate a transfer of data and control inputs. For example, prior to use of system 10 to transport live aquatic animals 16, a PC may be connected with the processor of control system 24 to download the required dissolved oxygen concentration for the animals 16 to be transported. Data may also be downloaded to the processor of control system 24 in relation to threshold levels of carbon dioxide. Conversely, after the transport of animal 16, data logged by the processor such as dissolved oxygen and carbon dioxide concentrations, air pressure, water pressure, and temperature may be transferred to the PC. Indeed, by provision of either a connection jack that is accessible on an exterior surface of container 12 or via the use of a wireless connection, such data may be transferred between a PC/laptop and the processor of control system 24 during transport of animals 16.
Operational power for the control system 24, water pump 28, air pump 30, and valve 54 is provided by a power pack 70. The power pack may comprise one or more sealed battery packs. When say two battery packs are provided, one may act as a backup in the event that the other is exhausted.
Use of the system 10 enables the transport of live aquatic animals 16 in a manner which is believed will achieve at least one of: reducing mortality rates; increase density of animals 16 that can be transported per liter of water; reduce weight of the system 10 by reducing the size of oxygen cylinder 18 required; as well reduce the volume of oxygen required due to regulated oxygen delivery. System 10 also enables optimization of water quality on the basis of species of animal being transported.
In one operational scenario, system 10 and in particular control system 24, may operate to maintain dissolved oxygen concentration in the range of it between 100% and 200% of saturation. Depending on the type and efficiency of oxygen diffuser 22, this dissolved oxygen concentration may require an oxygen flow rate of between 1-3 liters per minute from cylinder 18. Further, control system 24 may be programmed to maintain dissolved carbon dioxide concentration below a threshold level by operating water pump 28 to change the flow rate of water through the stripper 26. A safe threshold level of carbon dioxide concentration is dependant on the species of animal 16.
Figure 2 illustrates a second embodiment of the aquatic animal transport system 10a. In Figure 2 features which are the same or similar in function or operation as the first embodiment of system 10 of Figure 1 are denoted with the same reference number. The substantive difference between the systems 10 and 10a resides in their oxygen supply systems, and associated aspect of the control systems.
In the system 10a an oxygen supply system 17a comprises an oxygen selective membrane capable of transferring oxygen from a gas comprising or consisting of oxygen, such as air into water held in the first compartment. The oxygen selective membrane is disposed in a housing 76 located in the first compartment 14. Housing 76 has a water inlet 78 and a water outlet 80 enabling water within the first compartment to flow through the housing 76 and return to the first compartment 14. In addition the housing 76 has an air inlet 82 through which air from outside the first compartment can flow into housing and an air outlet 84 allowing air to be vented form the housing 76.
In this embodiment water is pumped through housing 76 via the pump 28. A conduit 86 branches from conduit 68 to the inlet 78. Valves V1 and V2 are placed in conduits 68 and 86 respectively. These valves are separately controllable by control system 24. Control of valve V1 provides a degree of control of the quantity of carbon dioxide removed from the water. Control of valve V2 provides a degree of control of dissolved oxygen concentration in the water.
Air is supplied to housing 76 via the air pump 30. A conduit 88 branches from conduit 69 to air inlet 82. Valves V3 and V4 are placed in conduits 69 and 88 respectively. These valves are separately controlled by control system 24. Control of valve V3 provides a second degree of control of carbon dioxide removal from the water. Control of valve V4 provides a second degree of control of dissolved oxygen concentration in the water.
In the system 10 a of Figure 2, the control system 24 includes an air pressure sensor 90 for providing signals indicative of air pressure within housing 76, and water pressure sensor 92 for providing signals indicative of water pressure within housing 76. The signals form these sensors are used by the control system 24 to control valves V2 and V4 enabling control the dissolved oxygen concentration levels in the water.
It will be appreciated that in this embodiment providing the oxygen supply system 17b as an oxygen selective membrane avoids the need for an oxygen vessel or cylinder and the diffuser of the first embodiment. Oxygen is provided by action of the membrane which allows oxygen to pass there through into water flowing though the housing 76. In all other respects the system 10 operates in the same manner as the system 10.
Now that an embodiment of the invention has been described in detail it will be apparent to those skilled in the relevant art that numerous modifications and variations may be made without departing from the basic inventive concepts.
For example, in alternate embodiments, one or more of the control system 24, carbon dioxide stripper 26, water pump 28, air pump 30, and power pack 70 may be located outside of compartment 14. In such instances, these pieces of equipment may be located in the second compartment 32 with appropriate conduits and/or cables simply passing through in a lid 34. However, when the system 10 is used for air transport, it is often a safety requirement that battery pack 70 and oxygen cylinder 18 be separated and moreover the power pack 70 disposed within the water contained in the first compartment 14. In a further variation with reference to the second embodiment of the system 10a shown in Figure2, each of the oxygen supply system 17a (which incorporates the oxygen selective membrane); and, the carbon dioxide stripper 26 may be provided with respective independent water pumps and air pumps; eliminating the need for the valves V1, V2, V3 and V4. In this variation the controller 24 independently controls each water pump and air pump to separately regulate the air and water flow to each of oxygen supply system 17a and the carbon dioxide stripper 26.
In yet another variation a cylinder of compressed air or other gas may be incorporated to provide a source of the gas passing through the carbon dioxide stripper 26 to sweep carbon dioxide from the stripper 26. In such variation the cylinder of compressed air/gas can be used in place of air pump 30 for at least the purposes of the stripper 26 with a value controlled by the controller 24 used to regulate gas flow through the stripper. Indeed if compressed air is used as the oxygen source as well then the air pump 30 could be dispensed with altogether and the cylinder of compressed air used for both the oxygen supply system incorporating the oxygen selective membrane and the carbon dioxide stripper. Indeed exhaust gas from the oxygen selective membrane can be used as the gas for sweeping carbon dioxide from the stripper 26.
All such modifications and variations together with others that would be obvious to persons skilled in the art are deemed to be within the scope of the present invention the nature of which is to be determined by the above description and the appended claims.
