Description

The present invention relates to an aquatic organism production infrastructure system and an aquatic organism production method that enable sustainable maintenance of a marine ecosystem by creating a high-quality marine environment that provides optimum seedlings and breeding environments for a wide variety of aquatic organisms.

The basis of human food environment is the agriculture, forestry and fisheries industry that works on the natural world to directly acquire wealth. In agriculture, soil improvement, variety improvement, and technological innovation of vegetable factories and food factories are progressing, and the efficiency of production process is improved. On the other hand, although the fishery industry (fishery) is developing some complete farming technology, economic fluctuations due to abundant and non-fish are still inevitable, and it is represented by warming gas. Adverse effects on the global environment lead to marine acidification due to an increase in harmful and toxic plankton and an increase in atmospheric CO ₂ concentration, and the resulting impact on organisms such as shellfish is in danger of resource depletion. Is.

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

For this reason, it is practiced to catch juveniles and immature fish of the target organisms and grow aquatic organisms using various dedicated equipment made for this breeding. Specifically, a method of aquaculture on the sea surface using a cage surrounded by a fish net with a floating body (Japanese Patent Laid-Open No. 6-007056, etc.), a method of aquaculture using a breeding water tank installed on land (Japanese Patent Laid-Open No. 2008-283896, etc.), seedlings Aquaculture (Japanese Patent Laid-Open No. 2007-082466) is carried out in which fry and shellfish raised from fishery are released to the coast of the sea area targeted for fishing and supplemented with natural fishery resources that are on the decline. For example, in marine fish farming using the subdivision method, there is a strong movement to improve management by cultivating bluefin tuna, butterflies, ques, kawahagi and other high-priced fish species that have not been cultivated so far. The proportion of high-grade marine products cultivated tends to increase.

However, these aquaculture methods have the negative effects of overfeeding and overcrowding on coastal waters, large amounts of antibiotics and formalin, and the production of medicated marine products with a wide variety of therapeutic agents, resulting in cultivated fisheries. The result is that the catch is overwhelmingly small compared to the total number released and the yield is poor. It also imposes laws and regulations to prevent environmental pollution and reduces the amount of drugs used to promote the safety of farmed fish, but none of these measures are perfect. Furthermore, in order to migrate and cultivate giant fish such as tuna, aquaculture cages with a diameter of at least 100 m are required, but in reality it is difficult to obtain such an installation location due to the relationship with existing fishing grounds, and fishing rights. It is difficult to participate in a general business entity because of the above.

Under such circumstances, Patent Document 1 discloses an aquatic organism breeding device. This breeding device reduces cannibalism between aquatic organisms, struggles between individuals, infection of diseases, etc. by subdividing aquatic organisms or enabling well-managed breeding of aquatic organisms. It is said to increase the rate. In addition, the breeding environment can be cleaned by injecting water and draining water from each breeding container, and various breeding conditions can be set by injecting water from each breeding container, and many types of aquatic organisms can be bred. It is said that.

Japanese Unexamined Patent Publication No. 2009-44979 (paragraphs [0021], [0039], [0049])

However, the breeding device of Patent Document 1 is only a transient breeding system because it is far from the marine environment created by the natural world in which aquatic organisms are subdivided and managed individually from other types of aquatic organisms. .. Aquatic organisms are only bred in one breeding container and are bred individually. In addition, because it is subdivided, it may cause stress on aquatic organisms.

In addition, while the world's fishing vessel production has peaked at around 90 million tons, the aquaculture industry is supporting the increase in fishery consumption, so appropriate management and utilization of fishery resources. At the same time, aiming for the sustainable development of the aquaculture industry is an important issue in securing the supply of marine products.

It is also an important issue to reduce the burden on the environment while further developing the world's aquaculture industry and reducing the burden on natural fishery resources.

Therefore, the present invention is an aquatic organism production infrastructure system and aquatic life that can reproduce the marine ecosystem in a marine environment formed in isolation from the natural sea and build an unprecedented industrial base for fisheries and fisheries. Provide a biological production method. Specifically, it realizes the functions provided by the vast ocean and reproduces the natural natural food chain that is the aquatic production process of primary production (primary production), secondary production, tertiary production and quaternary production.

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 in isolation from the natural sea 49. If a filtered seawater intake well 3 can be excavated underground from the seabed, passed through a water pipe 5 via a pump 4, and underground seawater (filtered seawater) can be taken into this system, it can be located at any position on land. It can be installed, and it can be applied not only in coastal areas but also in areas far from the coast by installing a water pipe 5 that is a pipeline necessary for transporting seawater and increasing the transport pressure of the pump 4. be. In addition, this system is equipped with a power generation facility 1 capable of generating electricity as a power source by using thermal power, geothermal heat, sunlight, or the like. The thick black line (square or arc) in the figure indicates a gate that can be opened and closed to partition adjacent areas.

The control center 2 of this system is a management system that controls comprehensive control, command, and processing of this system, gate control, lighting management system, seawater quality control system (oxygen concentration, seawater temperature, nutrient concentration, etc.), It is equipped with various devices such as a water flow adjustment system and software functions.

Since the ocean area on the earth is about 361.06 million km ² and the total amount of seawater is about 1,349.93 million km ³ , the amount of seawater in the entire system is insignificant compared to the global scale. This system is feasible.

[Seawater pumping, storage, and supply process]
The filtered seawater intake facility takes in the filtered seawater that passes through the water supply pipe 5 from the filtered seawater intake well 3 via the pump 4 into this system, and the seawater used is underground seawater, deep sea water, and coastal water. Any general seawater may be used, but there are various merits when using underground seawater.
Underground seawater can be produced in a planned manner because the water temperature, salt content, and pH are stable throughout the year, and because the dissolved oxygen concentration is low, there are no Escherichia coli or general bacteria, and naturally pathogenic bacteria and viruses. Since most of them are aerobic, the possibility of contamination in each cell is extremely low. Also, most anaerobic bacteria cease activity or die due to the inclusion of oxygen when used in this system. Of course, when using general seawater other than underground seawater, bacteria and contaminants in the seawater are removed by appropriate seawater adjustment means, and the seawater is filtered (adjusted) so that the concentration of nutrients is appropriate. However, when deep sea water is used, it is clean, but at a low temperature, the temperature is raised to around 20 degrees by geothermal heat or the like. In this system, groundwater (freshwater) well pumping devices 24A, 24B are provided, and the pumped groundwater (freshwater) is bred through the groundwater separation basins 25a, 25b, 25c, 25d, and the breeding canals 29A, 29B, 29C, 29D, 29E. Can be supplied to.

The filtered seawater is stored in a plurality of intake cells 6A, 6B, 6C in the system. The plurality of intake cells 6A, 6B, 6C are connected to the water pipe 5 via a gate, and in FIG. 1, the plurality of intake cells 6A-6B-6C are connected in series by the filtered seawater distribution channels 6a and 6b. However, a plurality of intake cells 6A, 6B, 6C may be connected in parallel by a 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 amount, and is adjusted to be in the state of filtered seawater that is appropriate for aquatic organisms, and is oxygen-rich as necessary. The filtered seawater can be supplied into this system. To make oxygen rich, nanobubbles using a fine bubble generator and a technique for increasing the amount of dissolved oxygen using an oxygen dissolving tower can be applied.

[Recycling and water discharge of seawater]
The seawater to be used can be recycled in a closed manner by removing the pollutant substances generated during the operation of this system, but the pollutant source substances are removed to make the seawater clean and then discharged to the natural world. It is also possible. The seawater treatment facility 46 performs water discharge treatment for passing the used filtered seawater through the drainage channel 47 and discharging it to the sea surface 50, and each sewage seawater / sediment treatment facility 35A, 35B, 35C, 35D. , 35E and drainage channels (not shown) are connected in series or in parallel, and the wastewater treated by each sewage seawater / sediment treatment facility 35A to 35E is discharged to the sea surface 50 via the seawater treatment facility 46. To.

[Production (growth) of swimming aquatic organisms]
The breeding of aquatic organisms is carried out in the breeding canals 29A, 29B, 29C, 29D, 29E, which 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 tank for general aquaculture equipment (10 m ^{3 to} 100 ^{m 3} ) and a cage for ^{marine aquaculture (1,000 m 3} to 1,000 m 3). It is 150 to 1,000 times larger than ^{20,000 m 3).} Compared to the water depths of 10 to 30 m and widths of 100 m to 300 m in the breeding canals 29A to 29E, tuna with a body length of 2.5 m are only minute, and this system does not grow in a crowded state like a poultry farm. It provides a marine environment in which aquaculture organisms that grow in clean coastal waters and offshore waters can be cultivated, such as free-range chickens in an appropriate environment.

Seaweed forests 33a, 33b, 33c, and 33d are provided in the breeding canals 29B to 29E, respectively, and seaweeds such as kelp and wakame seaweed can be grown, but organic matter in seawater is decomposed as needed. It grows seaweed and seaweed that can be used to purify seawater by absorbing nutrients and carbon dioxide and supplying oxygen. In addition, by breeding tall seaweed and seagrass and installing artificial collision cushioning materials near the walls of the breeding canals 29A to 29E, collision of tuna swimming fish at high speed is prevented. ..

The target of aquatic organisms produced in this system is not limited to fish, and any organisms that can coexist in the environment of breeding canals 29A to 29E, such as shrimp, crabs, and shellfish, are bred together. Non-swimming organisms store an appropriate amount in an underwater net container 54 in the canal and grow in an environment where seawater circulation is smooth. At this time, it is possible to prevent the outbreak of shellfish poisoning by controlling the planktons grown in this system. In addition, according to the scale of this system, the influence of water pollution caused by excrement of aquatic organisms can be reduced, and the purification power of organisms (microorganisms, plankton, shellfish, etc.) inhabiting the breeding canals 29A to 29E provides sufficient cleanliness. Can be maintained.

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

By providing a cell dedicated to feeding, contamination in the adjacent breeding canal is suppressed due to the influence of leftover food, etc., and it is easy to maintain the cleanliness in the breeding canal. As a result, the habitat of other aquatic organisms cultivated in the breeding canal can be maintained stably and easily, and an appropriate production environment can be established. In addition, there is no need to select food that does not cause contamination.

[Aquatic organism food procurement and feeding process]
Fish food is said to account for about half of the breeding costs. This system can store and use artificial feed with various effects and features as fish feed in the artificial feed storage 52, but basically it uses raw live feed that is originally eaten in the natural world. It has live feed farms 18A, 18B, 18C, 18D so that it can be fed. The movement of live feed from the live feed breeding farms 18A to 18D to the feed field cells 26A, 26B and the feed field area cells 27a, 27b is carried out via the live feed distribution tanks 18a, 18b, 18c, 18d, and the live fish movement waterways 22a, 22b. , 22c, 22d, 22e, 22f, 22g, 22h, 22i, 22j. Small fish, shrimp and other small organisms, phytoplankton and zooplankton as live bait may be stored in the natural fish storage tank 19 for bait from the captured natural fish sea surface cage 20 through the natural live fish supply channel 20a. , The seedlings seeded in the environmental cell 11 and supplied to each live feed breeding ground 18A to 18D may be used.

[Capture and capture process of aquatic organisms]
Among the aquatic organisms that are ready to be shipped, those that swim are moved from the breeding canals 29C, 29D, 29E, 29F to the capture area cells 27A, 27B and the capture cell 28, captured, and refrigerated or frozen in the refrigerator freezer 53. It is ready to be shipped as a product. That is, by inducing the aquatic organisms to be shipped to the breeding canals 29C, 29D, 29E, 29F in advance and capturing them in the capture area cells 27A, 27B and the capture cells 28, overfishing of unnecessary types and sizes of aquatic organisms is avoided. In addition to being able to increase the yield as a product, it is possible to reduce the pollution of seawater associated with capture by using a cell dedicated to capture. At the same time, by providing a space dedicated to capture, it is possible to take a capture method that is easier or less damaging to the product, which in turn leads to an increase in profit margin without degrading the commercial value of the product. Furthermore, it contributes to the maintenance of an environment suitable for growth in the breeding canal.

[Hatching center, seedling process]
This system has a plurality of environmental cells 11 for seeding and seedling of aquatic organisms, and can create a marine environment capable of spawning and hatching and obtain fry thereof. Phytoplankton and zooplankton, which are necessary for the growth of fry, will be secured outside the breeding canal and will be provided together with seawater as needed. The environmental cell 11 is composed of a tidal flat tank 17, a seaweed bed tank 15, 16 and a seaweed forest cell 12, and a hatching center 13 and 14, which reproduces the environment of the coastal sea area and enables spawning and fry growth of various aquatic organisms. And.

[Countermeasures for emergencies]
If water quality abnormalities occur in this system, it may damage the aquatic organisms that are being bred. In order to prevent or minimize the damage, sensors installed in various parts of the system constantly monitor changes in water quality (water temperature, nutrient concentration, light intensity, dissolved oxygen amount, etc.), and the values are set. If the dangerous value is exceeded, the aquatic organisms swimming in the problem area will be moved to the adjacent feeding ground cell or breeding canal. At this time, the feeding ground cell, the breeding canal, and the like always have two or more openable gates so that a dead end does not occur and there is no escape, and the connection and isolation are performed by opening and closing these gates. In addition, when evacuating, a fish collecting light device or the like may be used as an aid for smooth movement. Specifically, if the sensor detects that the environment inside the breeding canal is unsuitable for the living environment of aquatic organisms, it will automatically or manually move to an adjacent feeding cell or another breeding canal. Do and prevent the spread of the damage. The gate can be opened and closed automatically or manually, and by effectively advancing the movement by lighting and blinking with a fish collecting light device or the like, it is possible to move without any contact with swimming aquatic organisms.

2 to 4 are model diagrams of breeding canals 29A to 29E, FIG. 2 is a basic model, FIG. 3 is a sandy bottom model, and FIG. 4 is a model in which seaweed and seagrass are grown on sandy ground. Underwater net containers 54 in the canal are arranged on both sides of the breeding canal, and lighting that illuminates the water and also functions as a fish collecting light device is installed.

[Flowing process of breeding canal 1]
5A and 5B are views showing the shapes of the breeding canals 29B and 29C, FIG. 5A is a plan view, and FIGS. 5B to 5D are cross-sectional views seen from the side surface. The side surfaces of the breeding canals 29B and 29C show unevenness in which the width increases or decreases, and in connection with this, the depth to the bottom surface also increases or decreases. Therefore, the flow velocity is slow in the region where the bottom surface and width are larger than the standard, and the flow velocity is faster in the region where the bottom surface and width are smaller than the standard. The environment can be realized. In addition, the seawater of the breeding canals 29A, 29B, 29C is the canal adjustment gates 43A, 43B, 43C, 43D, 43E, 43F, 43G that open and close the feeding area cells 26A, 26B, the capture area cell 27A, and the feeding area cell 27a. , The flow can be changed by the change of the water level due to the open / closed state of 43H. Each canal adjustment gate has closed gates 43A ₁ , 43B ₁ , 43C ₁ , 43D ₁ , 43E ₁ , 43F ₁ , 43G ₁ , 43H ₁ , which can completely block the inflow and outflow of seawater. It is composed of possible open gates 43A ₂ , 43B ₂ , 43C ₂ , 43D ₂ , 43E ₂ , 43F ₂ , 43G ₂ , 43H _2.

[Breeding canal flow process 2]
In FIG. 5B, since all the closed gates 43A _{1 to} 43H ₁ are open, the water levels of the breeding canals 29A, 29B, and 29C are in a uniform state.

In this situation, if the closed gate 43B ₁ is opened, the seawater naturally moves to the low water level side downstream, so that a flow of seawater can be created in the breeding canal, and the flow velocity changes due to the change in the cross-sectional area of the flow path. Changes also occur. _{In FIG. 5D, the closed gate 43B 1 located in the breeding canal 29B and the closed gate 43D 1} located in the breeding canal 29C are closed at the stage of supplying seawater to the breeding canal 29B and the feeding canal cell 26B. level between the closed gate _{43B 1} -43D 1 is increased. In this situation, if the closed gate 43D ₁ is opened, the seawater naturally moves to the low water level side downstream, so that a flow of seawater can be created in the breeding canal, and the flow velocity changes due to the change in the cross-sectional area of the flow path. Changes also occur. In this way, by closing the closed gate and raising the water level of the closed cell, and then opening the closed gate located in the adjacent cells with different water levels, seawater can flow from the high water level side to the low water level side. It utilizes the phenomenon of moving naturally.

[Capture and capture process of aquatic organisms]
The capture of aquatic organisms in this system is carried out in the capture area cells 27A and 27B or the capture cell 28. Here, an example of capturing by the capture area cell 27B will be described with reference to FIG. 7.

First, the swimming aquatic organisms to be captured are urged to move to the capture area 27B by feeding, collecting light, or the like. When it can be confirmed visually or by a sensor or the like that aquatic organisms have entered the capture area 27B, 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 closed.

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

When it is confirmed that aquatic organisms below the product level 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 aquatic organisms to be captured can be in a state of swimming 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 becomes an amount suitable for capture, asphyxia is caused by an electric shock. It is captured by a capture method suitable for aquatic organisms, such as putting it in a state, scooping it up with a net, or fishing it.

[Aquatic organism feeding, 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 opening, FIG. 11 is predation, and FIG. 12 is. The fish are moved to the canal, and FIG. 13 shows each state of feeding area cell washing. In the following, 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, 43K are used as closed gates, and the 43i, 43j, 43l, 43k attached to them are used as a mesh-like net gate.

In FIG. 8, before the food supply, the filtered seawater supply gate 40n and the canal adjustment gates 43I, 43J, 43L, 43K, 44e, 44f, 44g, 44h are completely closed, and the recovery gates 34d _{1-1 to 34d 1- Reference numeral 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 mesh-like net gates 43i, 43j, 43l, 43k attached to the adjustment gates 43I, 43J, 43L, 43K for each canal 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 step, live feed from the live feed breeding farm 18D and feed from the artificial feed storage 52 are charged into the feed field area cell 27b. At this time as well, since the state of each gate is basically the same as that before the food supply, 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 and the net gates 43i and 43j are opened to guide aquatic organisms swimming in the breeding canal 29D into the feeding area cell 27b. The aquatic organisms in the feeding area cell 27b are obstructed 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 the inflow of food and the like into the breeding canals 29D and 29E. At this time, stop feeding live feed and feed.

In FIG. 12, in the step of moving the fish to the breeding canal, the adjustment gate 43J for the canal is opened, the fish collecting light device 32D is turned on, and the fish is guided 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). Furthermore, by gradually closing the canal adjustment gates 43J and 43I in accordance with the movement of fish, the inflow of contaminants into the breeding canal 29D is suppressed as much as possible. The contaminants that have flowed into the breeding canal 29D are mitigated within the distance of the guide channel wall 30d. When the total amount of water in the feeding area cell 27b and the catching area cell 27B reaches the predetermined reference value, the canal adjustment gates 43J and 43I are completely closed.

In FIG. 13, in the feeding area cell cleaning step, all the seawater in the feeding area cell 27b and the capture area cell 27B is collected in the sewage seawater / sediment collection tank 34D through the _{sediment collection pipes 34d 1 to 34d 8.} The filtered seawater supply gate 40n is opened and fresh filtered seawater is injected to wash the feeding area cell 27b and the capture area cell 27B. After the cleaning is completed, the canal adjustment gates 43I, 43J, 43L, 43K are opened to return to the state shown in FIG.

As described above, according to this system, it is possible to grow in an environment closer to nature for living organisms, unlike the system of aquaculture in an abnormally overcrowded environment such as closed land aquaculture that has become widespread in recent years. Since the breeding environment (water quality, water temperature, water flow, etc.) can be artificially controlled, there are no restrictions on the target fish species depending on the installation area as in sea surface cultivation, and it is effective without being affected by the water temperature, etc. due to the four seasons. It is possible to grow aquatic organisms in a favorable environment. In addition, this system, which has a huge volume, makes it possible to grow multiple aquatic organisms at the same time, and one company can grow aquatic organisms from multiple angles, or multiple fishermen form a consortium and differ. It will be possible to produce aquatic organisms.

In addition, for fishermen, it does not require a large number of fishing boats, it is possible to realize stable management that is not affected by the weather and climate, it does not require harsh labor under bad weather, and the aging population is coming. It will be a business with high social contribution that expands the possibilities of employment in society. In particular, creating a marine environment on land is industrially useful as an industrial infrastructure suitable for an aging society for Japan in the future, in terms of providing a safe working environment for the elderly who are physically weak.
