Description

  The present invention relates to an aquatic organism production infrastructure system and an aquatic organism production method capable of creating a high-quality marine environment that provides optimal seedlings and breeding environments for a wide variety of aquatic organisms and enabling the sustainable maintenance of marine ecosystems.

The core of the human food environment is the agriculture, forestry and fisheries industry that works directly with nature to acquire wealth. Agriculture has improved soil and varieties, as well as technological innovations in vegetable factories and food factories. On the other hand, in the fishery industry (fishing), although full aquaculture technology is being developed, economic fluctuations due to fish and fish are still unavoidable and are represented by greenhouse gases. The adverse effects on the global environment have led to ocean acidification due to an increase in harmful and toxic plankton and an increase in atmospheric CO ₂ concentration, and the situation is in danger of resource depletion due to the impact on crustaceans and other living organisms. It is.

  Under these circumstances, the world population in 2050 is said to reach about 9.7 billion (1.3 times the current level), and many developing countries with population problems are increasing their food dependency on the ocean. In Japan, the annual consumption of seafood per capita is extremely large, five times the world average, and coupled with the global spread of Japanese food that uses a lot of seafood, the demand is increasing on a global scale.

  For this reason, aquatic organisms are raised using various special facilities created for breeding, catching young and immature fish of the target organism. Specifically, a sea surface aquaculture method using a cage surrounded by a fishnet with a floating body (JP-A-6-007056, etc.), a culture method using a breeding aquarium installed on land (JP-A-2008-283896, etc.), seedlings and seedlings Cultivation fisheries (Japanese Patent Application Laid-Open No. 2007-082466) and the like are carried out to release juveniles and larvae raised from the sea to the coast of the fishery target sea area and supplement natural fishery resources that are decreasing. For example, in marine fish farming using the split type, there are strong moves to improve management by cultivating high-price fish species that have not been cultivated, such as bluefin tuna, sturgeon, cucumbers, and riverfish. The aquaculture ratio of high-end seafood tends to increase.

  However, these aquaculture methods induce the adverse effects of overfeeding and overcrowding of coastal waters, the production of medicinal marine products that use large amounts of antibiotics and formalin, and many types of therapeutics. The result is that the yield is poor compared to the total number released. In addition, laws and regulations have been imposed to prevent environmental pollution, and the amount of drugs used to appeal the safety of farmed fish has been reduced, but none of them is a perfect measure. Furthermore, in order to cultivate giant fish such as tuna, it is necessary to have an aquaculture cage with a diameter of at least 100m. However, in reality, it is difficult to obtain such an installation location due to the relationship with existing fishing grounds, Therefore, it is difficult for general corporate bodies to participate in business.

  Under such circumstances, Patent Document 1 discloses an aquatic animal breeding apparatus. In this breeding device, aquatic organisms can be subdivided or managed individually, thereby reducing cannibalism and inter-individual struggle between aquatic organisms and disease infections. It is said to increase the rate. In addition, the breeding environment can be cleaned by water injection and drainage for each breeding container, and various types of breeding conditions can be set by water injection for each breeding container, and various types of aquatic organisms can be bred. It is said that.

JP 2009-44979 A (paragraphs [0021], [0039], [0049])

  However, the breeding device of Patent Document 1 is only a temporary breeding system because it is far from the marine environment formed by the natural world in which aquatic organisms are subdivided and managed separately from other types of aquatic organisms. . Aquatic organisms are only raised in one breeding container and are raised individually. Moreover, since it is subdivided, it may give stress to aquatic organisms.

  In addition, the production volume of fishing boats around the world has reached a peak of around 90 million tons, and the aquaculture industry supports the increase in the consumption of fishery products. At the same time, aiming for the sustainable development of the aquaculture industry is an important issue in securing the supply of fishery products.

  It is also an important issue to further reduce the burden on the environment while further developing the aquaculture industry in the world and thereby reducing the burden on natural marine resources. In particular, the environment of the vast ocean is not all uniform, and even at the same latitude and longitude, the upper and lower layers are stacked, so it is not necessarily good for growth. Because it is not an environment, it is important to establish an efficient production infrastructure system that is not affected by the effects of the marine environment, topography, and weather.

  Therefore, the present invention provides an aquatic organism production infrastructure system and an aquatic organism that can reproduce a marine ecosystem in a marine environment formed isolated from the natural sea and can build an unprecedented aquatic fishery industry base. Provide a biological production method. Specifically, it realizes the functions provided by the vast ocean and reproduces the natural food chain linked to primary production (basic production), secondary production, tertiary production and quaternary production, which are aquatic organism production processes. Provide an infrastructure (system structure that provides an industrial base for aquatic production) that enables production of aquatic organisms to be used.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram of an aquatic organism production infrastructure system according to an embodiment of the present invention. This system creates a marine environment formed isolated from the natural sea 49. Any location on land where the filtered seawater intake well 3 is excavated from the bottom of the sea to the ground, passed through the water pipe 5 via the pump 4 and the groundwater (filtered seawater) can be taken into the system. It can be installed, and can be applied not only in coastal areas, but also in areas far from the coast by providing water pipes 5 that serve as pipelines necessary for transporting seawater and increasing the transport pressure of pumps 4 is there. In addition, the present system includes a power generation facility 1 that can generate electricity using thermal power, geothermal heat, sunlight, or the like as the power source. In addition, the thick black line (square shape or arc shape) in the drawing indicates an openable / closable gate that partitions adjacent regions.

  The control center 2 of this system is a management system that controls the overall control, command and processing of this system, gate control, lighting management system, seawater quality control system (oxygen concentration, seawater temperature, nutrient concentration, etc.), Various equipment and software functions such as a water flow adjustment system are installed. Specifically, each treatment management (seawater to various treatments) system, each inflow gate control, analysis management system of the cause of death occurring in each facility, analysis management system of survival rate and number of each hatching plant, each facility Night lighting system, mainstream / gate / waterway adjustment system, sound wave species and intensity management system at the time of feed inflow, each fish type capture system, each type of fish breeding number management system, hatching rate analysis management system for each hatchery plant, Plankton floor area ratio analysis management system, fish health condition analysis management system for each facility, mainstream sluice water volume adjustment system, average temperature analysis management system for each facility, fish predation status analysis management system, water quality (seawater and Fresh water) analysis management system, inflow adjustment (breeding fish) analysis management system, bad bacteria count analysis management system at each point, pollution degree analysis management at each point System, feeding management system for main breeding, quality management system for each fish type, refrigerated / frozen inventory management system, inflow adjustment (bait) management system, analysis status management system, fresh water concentration management system, transparency number management system, oxygen concentration management system Software functions such as a water temperature adjustment management system, a salinity concentration management system, a movement management system between facilities, a nanobubble concentration management system, and a capture status management system are installed.

The total amount of seawater possessed by this system as a whole is 1,131,350 million m ^3, which is 560 million times larger than a general tuna sea surface aquaculture cage (20,000 m ³ ). As such, it provides an industrial base that can produce all marine marine products. In addition, since the ocean area on the earth is about 361.06 million km ² and the total amount of sea water is about 1,349.93 million km ³ , the sea water volume of the entire system is slightly smaller than the global scale. The system is only possible, and this system is feasible.

[Seawater pumping, storage and supply process]
The filtered seawater intake facility incorporates filtered seawater that passes through the water pipe 5 from the filtered seawater intake well 3 through the pump 4 into this system. The seawater to be used is underground seawater, deep seawater, coastal water General seawater may be used, but there are various merits when using groundwater.
Groundwater has stable water temperature, salinity, and pH throughout the year, so that planned production can be realized, and since the dissolved oxygen concentration is low, there are no coliforms or general bacteria, and naturally pathogenic bacteria and viruses Since most of them are aerobic, the possibility of mixing into each cell is extremely low. Also, anaerobic bacteria mostly stop their activity or die because they contain oxygen when used in the system. Of course, when general seawater other than underground seawater is used, seawater bacteria and contaminants are removed by appropriate seawater adjustment means, and seawater is filtered (adjusted) to obtain an appropriate nutrient concentration. However, when using deep ocean water, it is clean but at low temperature, it is heated to around 20 degrees by geothermal heat or the like. In this system, groundwater (freshwater) well pumping devices 24A and 24B are provided, and the pumped groundwater (freshwater) is reared in the breeding canals 29A, 29B, 29C, 29D, and 29E through the groundwater separation tanks 25a, 25b, 25c, and 25d. Can be supplied.

  The filtered seawater is stored in a plurality of water intake cells 6A, 6B, 6C in the present system. The plurality of intake cells 6A, 6B, 6C are connected to the water pipe 5 via the gate. In FIG. 1, the plurality of intake cells 6A-6B-6C are connected in series by the filtered seawater distribution water channels 6a and 6b. However, a plurality of intake cells 6A, 6B, 6C may be connected in parallel by the filtered seawater distribution channel. The filtered seawater in the intake cells 6A, 6B, and 6C is monitored for water quality such as water temperature and dissolved oxygen content, and is adjusted to be in the state of filtered seawater that is suitable for aquatic organisms. The filtered seawater can be supplied into the system. In order to make oxygen rich, it is possible to apply a technique for increasing the amount of dissolved oxygen using a nanobubble generated by a fine bubble generator and an oxygen dissolution tower.

[Seawater circulation and discharge]
The seawater to be used can be closed and recycled by removing the pollutant material generated during the operation of this system, but it is released into the natural world after removing the pollutant material to form a clean seawater state. It is also possible. The seawater treatment facility 46 performs a water discharge treatment for allowing the used filtered seawater to pass through the drainage channel 47 and discharge it to the sea surface 50, and each sewage seawater / precipitate treatment facility 35A, 35B, 35C, 35D. 35E and a drainage channel (not shown) connected in series or in parallel, the wastewater treated by each of the sewage seawater / precipitate treatment facilities 35A to 35E is discharged to the sea surface 50 via the seawater treatment facility 46. The

[Production (growth) of swimming aquatic organisms]
Aquatic organisms are raised in breeding canals 29A, 29B, 29C, 29D, and 29E that provide a breeding environment. One of the breeding canals 29A to 29E is 3 million m ^{3 to} 22.5 million m ³ , and is a general aquaculture equipment aquarium (10 m ^{3 to} 100 m ³ ) or a sea surface aquaculture cage (1,000 m ³ to It is a scale of 150 to 1,000 times or more compared with 20,000 m ³ ). The tuna with a body length of 2.5m is only a small one compared with the water depth of 10-30m and the width of 100m-300m in the breeding canals 29A to 29E, and this system is not an overcrowded breeding culture like a chicken farm. It provides a marine environment that can nurture aquatic organisms that grow in clean coastal and offshore waters, such as free-ranged chickens that are kept free in an appropriate environment.

  The breeding canals 29B to 29E are provided with seaweed forests 33a, 33b, 33c, and 33d, respectively, which can grow seaweeds such as kelp and seaweed, but if necessary, decompose organic matter in seawater. It grows seaweed and seaweed that can absorb nutrient salts and carbon dioxide and supply oxygen to help purify seawater. Also, near the walls of the breeding canals 29A to 29E, tall seaweeds and seaweeds are bred and artificial collision buffering materials are installed to prevent collisions of fish that swim at high speeds of tuna. .

  The target of the aquatic organisms produced in this system is not limited to fish, and any shrimp, crab, shellfish and other organisms that can live together in the environment of the breeding canals 29A to 29E are reared together. A living organism that does not swim is stored in an underwater net container 54 in the canal, and is grown in an environment where the circulation of seawater is performed smoothly. At this time, it is possible to prevent the occurrence of shellfish poison etc. by controlling the plankton grown in this system. In addition, according to the scale of this system, it is possible to reduce the influence of water pollution due to excrement of aquatic organisms, and the cleansing power by organisms (microorganisms, plankton, shellfish, etc.) that live in the breeding canals 29A to 29E is sufficiently clean Can be maintained.

[Feeding and feeding the swimming aquatic organisms]
This system feeds aquatic organisms that are likely to contaminate the seawater in the system in a dedicated cell, and has feeding ground cells 26A and 26B and feeding ground area cells 27a and 27b. The feeding cell 26A is connected to the breeding canals 29A, 29B, and 29F through gates, and feeds aquatic organisms that grow on the breeding canals 29A and 29F. The feeding cell 26B is connected to the breeding canals 29B and 29C through gates, and feeds aquatic organisms growing on the breeding canals 29B. The feeding area cell 27a is connected to the breeding canals 29C and 29D through a gate, and feeds aquatic organisms growing on the breeding canals 29C. The feeding ground area cell 27b is connected to the breeding canals 29DF, 29D, and 29E through gates, and feeds aquatic organisms that grow on the breeding canals 29D and 29F.

  By providing a cell dedicated to feeding, the contamination of the adjacent breeding canal is suppressed by the influence of uneaten food, etc., and it is easy to maintain cleanliness within the breeding canal. Thereby, it is easy to stably maintain the growth environment of other aquatic organisms bred in the breeding canal, and an appropriate production environment is prepared. In addition, there is no need to select food that does not cause contamination.

[Procurement of aquatic food, feeding process]
Fish food is said to account for about half of the breeding costs. In this system, artificial feed having various effects and features can be stored and used in the artificial feed storage 52 as a fish feed. Basically, live feed that is naturally eaten in the natural world is used. Live feed farms 18A, 18B, 18C, 18D are provided so that they can be eaten. The movement of the live food from the live food breeding grounds 18A to 18D to the feed ground cells 26A, 26B and the food ground area cells 27a, 27b is performed via the live food distribution tanks 18a, 18b, 18c, 18d. , 22c, 22d, 22e, 22f, 22g, 22h, 22i, and 22j. Small fish, shrimp and other small organisms as live bait, phytoplankton and zooplankton may be those stored in the feed natural fish storage tank 19 from the captured natural fish sea surface cage 20 through the natural live fish supply channel 20a. Alternatively, seeds seeded in the environmental cell 11 and supplied to the live food breeding farms 18A to 18D may be used.

[Capturing and capturing aquatic organisms]
Among the aquatic organisms that can be shipped, those that swim are moved from the breeding canals 29C, 29D, 29E, and 29F to the capture area cells 27A, 27B and the capture cell 28 and captured, and refrigerated or frozen in the refrigerated freezer 53. Be ready for shipment as a product. That is, aquatic organisms to be shipped are guided to the breeding canals 29C, 29D, 29E, and 29F in advance and captured by the capture area cells 27A, 27B and the capture cell 28, thereby avoiding overfishing of aquatic species of unnecessary types and sizes. It is possible to increase the yield as a product, and to reduce the contamination of seawater accompanying capture by using a cell dedicated to capture. At the same time, by providing a capture-dedicated space, it is possible to take a capture method that is easier or less damaging to the product, leading to an increase in the profit rate without degrading the product value of the product. Furthermore, it contributes to the maintenance of an environment suitable for the growth within the breeding canal.

[Hatching Center, Seedling Process]
This system has a plurality of environmental cells 11 for seedling aquatic organisms, and can create a marine environment capable of spawning and hatching and obtain the fry. Phytoplankton, zooplankton, etc. necessary for the growth of fry will be secured outside the breeding canal and provided with seawater as needed. The environmental cell 11 is composed of a tidal flat tank 17, a seaweed bath 15, 16, a seaweed forest cell 12, and a hatching center 13, 14, and can reproduce the environment of the coastal sea area and lay eggs and fry of various aquatic organisms. And

[Emergency measures]
If water quality abnormalities occur in this system, it may cause damage to the aquatic organisms being bred. Sensors installed in various parts of the system constantly monitor water quality changes (water temperature, nutrient salt concentration, light intensity, dissolved oxygen amount, etc.) and set the numerical values in order to minimize or reduce the damage. If the risk value is exceeded, the aquatic organisms swimming in the problem area are moved to the adjacent feeding cell or breeding canal. At this time, the feeding cell and the breeding canal always have two or more gates that can be opened and closed so as to avoid dead ends and escapes, and the gates are connected and disconnected by opening and closing the gates. Further, when evacuating, a fish collection device or the like may be used as an aid for smoothly moving the evacuation. Specifically, if the sensor detects that the environment inside the breeding canal is inappropriate for the living environment of aquatic organisms, it can automatically or manually move to an adjacent feeding canal cell or another breeding canal. And prevent the damage from spreading. The gate can be opened and closed automatically or manually, and the movement can be performed without any contact with the aquatic organisms swimming by effectively moving the light by turning on and blinking with a fish collecting light device or the like.

  2 to 4 are model views of the breeding canals 29A to 29E. FIG. 2 is a basic model, FIG. 3 is a sandy model on the bottom surface, and FIG. 4 is a model in which seaweed and seaweed are grown on the sandy land. On both sides of the breeding canal, an underwater net container 54 in the canal is arranged, and illumination that irradiates the inside of the canal and also functions as a fish collecting light device is installed.

The side surfaces of the breeding canals 29B and 29C have irregularities with increased and decreased widths, and associated irregularities with increased and decreased depths to the bottom. Therefore, in areas where the bottom and width are increasing from the standard, the flow velocity is slow, and in areas where the bottom and width are decreasing from the standard, the flow velocity is high. An environment can be realized. In addition, the seawater of the breeding canals 29A, 29B, and 29C is a canal adjustment gate 43A, 43B, 43C, 43D, 43E, 43F, and 43G that opens and closes the feed station cells 26A and 26B, the capture area cell 27A, and the feed station area cell 27a. , 43H, the flow can be changed by changing the water level according to the open / close state. Each of the adjustment gates for canals has sealed gates 43A ₁ , 43B ₁ , 43C ₁ , 43D ₁ , 43E ₁ , 43F ₁ , 43G ₁ , 43H ₁ that can completely block the inflow / outflow of seawater, The open gates 43A ₂ , 43B ₂ , 43C ₂ , 43D ₂ , 43E ₂ , 43F ₂ , 43G ₂ , 43H ₂ are possible.

[Capturing and capturing aquatic organisms]
The aquatic organisms in this system are captured by the capture area cells 27A and 27B or the capture cell 28. Here, an example of capturing in the capture area cell 27B will be described with reference to FIG.

  First, swimming aquatic organisms to be captured are directed to move to the capture area 27B by feeding, fish collection light, or the like. When the aquatic organism has entered the capture area 27B by visual inspection or a sensor or the like, the canal adjustment gate 43I is closed in order to isolate it from the adjacent breeding canal 29D. At this time, all the gates other than the canal adjustment gates 43J and 43L are in a closed state.

  Of the aquatic organisms that have entered the capture area 27B, those that have not yet grown and are not suitable for capture are drawn into the feeding area cell 27b on the inner side by feeding, collecting light, or the like. At this time, a net-like net gate is installed in the canal adjustment gates 43J and 43L, and the net cannot pass through aquatic organisms of the product size. As a result, the capture target of the product size cannot enter the feeding area cell 27b and continues to swim in the capture area cell 27B.

  When it has been confirmed that aquatic organisms of the product level or lower that are not the target of capture have entered the feeding area cell 27b, the canal adjustment gates 43J and 43L are closed. By this. Since only the aquatic organisms to be captured can swim in the capture area cell 27B, an appropriate amount of seawater in the capture area cell 27B is extracted, and after the amount of seawater is suitable for capture, it is temporarily killed by an electric shock. Capture by the capture method suitable for aquatic organisms, such as state, scooping on the net, fishing.

[Aquatic feeding and feeding process]
8 to 13 are diagrams for explaining the state of the system in the feeding process. FIG. 8 is before feeding, FIG. 9 is feeding, FIG. 10 is gate open, FIG. 11 is predation, and FIG. Moving fish to the canal, FIG. 13 shows each state of feeding area cell washing. In the following description, the feeding area cell 27b will be described as an example, but the same applies to the feeding area cell 27a, and the basic steps are the same for the feeding area cells 26A and 26B. Further, the canal adjustment gates 43I, 43J, 43L, and 43K are used as sealed gates, and the 43i, 43j, 43l, and 43k attached to them are used as net-like net gates.

8, before food supply, filtered seawater supply gate 40n and canals for adjusting gate 43I, 43J, 43L, 43K, 44e, 44f, 44g, 44h is completely closed, the recovery gate _34d 1-1 _{~34d 1- 8} is completely open, and the filtered seawater from the filtered seawater intake cell 6B is supplied to the breeding canals 29D and 29E. Further, the net-like net gates 43i, 43j, 43l, 43k attached to the canal adjustment gates 43I, 43J, 43L, 43K are closed. Therefore, aquatic organisms swim only in the breeding canal 29D and cannot pass through the net gate 43i.

  In FIG. 9, in the feed supply process, live feed from the live feed breeding station 18 </ b> D and feed from the artificial feed reserve 52 are put into the feed area cell 27 b. At this time, basically, the state of each gate is the same as that before feeding, so that aquatic organisms swimming in the breeding canal 29D cannot pass through the net gate 43i. At this time, the filtered seawater supply gate 40n may be open or closed.

  In FIG. 10, in the gate opening step, the filtered seawater supply gate 40n is closed, the net gates 43i and 43j are opened, and aquatic organisms swimming in the breeding canal 29D are guided into the feeding area cell 27b. In addition, the aquatic organism in the feeding area cell 27b is blocked by the net gates 43l and 43k and cannot enter the breeding canal 29E.

  In FIG. 11, in the predation process, the canal adjustment gates 43J, 43L, and 43K are completely closed to prevent inflow of food and the like into the breeding canals 29D and 29E. At this time, input of live food and feed is stopped.

In FIG. 12, in the step of moving the fish to the breeding canal, the canal adjustment gate 43J is opened, the fish collection light device 32D is turned on, and the fish is led to the breeding canal 29D. Further, by opening the recovery gate _34d 1-1 _{~34d 1-8} recovering contaminants such as food and feces in precipitate recovery pipe _34d 1 _{~34d 8} with seawater (recovery process). Further, the inflow of contaminants into the breeding canal 29D is suppressed as much as possible by gradually closing the canal adjustment gates 43J and 43I in accordance with the movement of the fish. In addition, the contaminant which flowed into breeding canal 29D is relieved within the distance of the guiding channel wall 30d. When the total amount of water in the feeding area cell 27b and the capture area cell 27B reaches a predetermined reference value, the canal adjustment gates 43J and 43I are completely closed.

13, in the feeding grounds area cell washing process is collected in a sewage sea water, precipitate recovery tank 34D seawater feeding ground area cell 27b and capture area cell 27B is through all precipitate recovery pipe _34d 1 _{~34d 8.} The filtered seawater supply gate 40n is opened and fresh filtered seawater is injected to clean the feeding area cell 27b and the capture area cell 27B. After the cleaning is completed, the canal adjustment gates 43I, 43J, 43L, and 43K are opened to return to the state shown in FIG.

  As described above, according to the present system, it is possible to grow in an environment closer to nature for a living organism, unlike a system that is cultivated in an abnormal overcrowded environment such as closed land culture that has recently been spread. Since the breeding environment (water quality, water temperature, water flow, etc.) can be controlled artificially, there is no restriction on the target fish species depending on the installation area, as in sea surface aquaculture, and it is effective without being affected by water temperature etc. depending on the season It is possible to grow aquatic organisms in a rough environment. Moreover, according to this system with a huge volume, it is possible to grow multiple aquatic organisms at the same time. One company can grow aquatic organisms from multiple perspectives, and multiple fishery personnel can form different consortia. Aquatic organisms can be produced.

  In addition, fishermen can achieve stable management that is not affected by the weather and climate without requiring a large number of fishing boats. It will be a highly socially contributing business that expands the possibilities of employment in society. In particular, the creation of a marine environment on land is industrially useful as an industrial infrastructure suitable for an aging society for the future of Japan in terms of providing a safe working environment for elderly people who have lost their physical strength.
