Description

[Technical field]

[0001] The present invention relates to a cultivation system for aquatic organisms and plants that combines aquaculture and hydroponics. [Background technology]

[0002] Conventionally, an aquaponics system that combines aquaculture and hydroponics has been known (see Patent Document 1). A stacked aquaponics system (10a) described in Patent Document 1 is a water circulation system that simultaneously cultivates fish (22) and plants (34), and includes a breeding aquarium (20), plant containers (30) arranged in multiple stages above the breeding aquarium (20), and a siphon mechanism (40) and a water supply pipe (48) that circulate water between the breeding aquarium (20) and the plant containers (30).

[0003] This layered aquaponics system (10a) is structured so that waste and leftover food from the fish (22) in the breeding tank (20) is transferred to a plant container (30) by circulating water, and the waste and food are converted by the decomposition action of microorganisms into a source of nutrition for the plants (34), while at the same time purifying the water.

[0004] The breeding tank (20) and the plant container (30) need to maintain an environment in which the fish (22) and the plants (34) can grow. For example, the temperature, water quality, hydrogen ion exponent (pH), oxygen concentration, etc. of the water circulating through the breeding tank (20) and the plant container (30) need to be maintained. Although not mentioned in Patent Document 1, management work by an operator and management devices are required to actually maintain and manage an aquaponics system.

[0005] [Patent Document 1] JP 2017-29014 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the management tasks are diverse and very cumbersome for the workers. Even when multiple management devices are used, the burden on the workers is large when they have to operate each device.

[0007] Therefore, the present invention provides a cultivation system for aquatic organisms and plants that significantly reduces the burden on workers in terms of maintenance and management work. [Means for solving the problem]

[0008] The aquatic organism and plant cultivation system of the present invention is characterized by comprising an aquaculture section for housing and cultivating aquatic organisms together with water, a hydroponic cultivation section for housing and cultivating plants together with the water, a circulation path for circulating the water between the aquaculture section and the hydroponic cultivation section, a management means for managing the aquatic organisms, the plants, and the water, and a management control section for automatically controlling the management means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Not all of the configurations described below are essential requirements for the present invention.

[0012] Fig. 1 shows the overall configuration of a cultivation system 1 for aquatic organisms and plants (hereinafter simply referred to as "cultivation system 1") according to one embodiment of the present invention. In the cultivation system 1 of this embodiment, seawater W (including artificial seawater) is circulated to cultivate marine organisms 2, which are aquatic organisms, and marine plants 3, which are plants.

[0013] The cultivation system 1 has a breeding tank 4, which is an aquaculture section that houses and breeds marine organisms 2, and a cultivation tank 5, which is a hydroponic cultivation section that houses and cultivates marine plants 3. The breeding tank 4 and the cultivation tank 5 are connected by a circulation path 6A and a circulation path 6B. Seawater W is contained in the breeding tank 4, the cultivation tank 5, and the circulation paths 6A and 6B, and the seawater W is circulated by a circulation pump 7, which is a water supply device, in the following order: breeding tank 4 → circulation path 6A → cultivation tank 5 → circulation path 6B → breeding tank 4 → circulation path 6A → cultivation tank 5 →... Note that the circulation of the seawater W may be in the reverse direction, such as breeding tank 4 → circulation path 6B → cultivation tank 5 → circulation path 6A → breeding tank 4 → circulation path 6B → cultivation tank 5 →..., or the circulation direction may be changed as appropriate. A net member 8 is provided at the connection between the breeding tank 4 and the circulation paths 6A, 6B, and is structured to prevent the marine organisms 2 from entering the circulation paths 6A, 6B. The mesh of the net member 8 is formed smaller than the size of the marine organisms 2, and seawater W and excrement, which will be described later, can pass through the mesh, but the marine organisms 2 cannot.

[0014] The marine organisms 2 in this embodiment are edible aquatic organisms that can survive in seawater W, such as shellfish like abalone or saltwater fish. On the other hand, the marine plants 3 are halophytes like Salicornia, seaweed, seaweed, etc. Naturally, it is preferable that the marine plants 3 are also edible. The marine organisms 2 housed in the breeding tank 4 and the marine plants 3 housed in the cultivation tank 5 may each be one type, or multiple types may be present if they can coexist. In this embodiment, sunlight L is irradiated onto the marine plants 3 to enable photosynthesis, but an artificial light source (not shown) such as an LED may also be used.

[0015] The cultivation system 1 is equipped with a pH measuring device 9 that measures the hydrogen ion exponent (pH) of the circulating seawater W, and a salinity measuring device 10 that measures the salinity. The cultivation system 1 also has a camera device 11 that takes images of the breeding aquarium 4 and the cultivation aquarium 5, and is capable of detecting the color of the seawater W and the presence or absence of foreign matter in the seawater W. The camera device 11 is capable of taking images of at least the breeding aquarium 4 and the cultivation aquarium 5, and multiple camera devices may be provided. The cultivation system 1 also has a temperature sensor 12 that measures the temperature of the circulating seawater W.

[0016] The cultivation system 1 includes a storage tank 13 for storing fresh water F, and a container 14 for storing a composition M for artificial seawater, such as sodium chloride and minerals. The container 14 also contains a hydrogen ion concentration regulator P.

[0017] The excrement, carcasses, food, etc. of the marine organisms 2 are decomposed by microorganisms in the seawater W and absorbed as a nutrient source by the marine plants 3, but if the amount exceeds the decomposition capacity of the microorganisms or the absorption capacity of the marine plants 3, the excrement, carcasses, food, etc. are not decomposed or absorbed and flow together with the seawater W. Furthermore, substances generated during decomposition by the microorganisms may cause fouling of the seawater W. Since these fouling substances are undesirable for the marine organisms 2, the seawater W flowing through the circulation path 6B upstream of the breeding tank 4 and downstream of the cultivation tank 5 is filtered by a filtration device 15, and clean seawater W is allowed to flow into the breeding tank 4.

[0018] The cultivation system 1 is equipped with a temperature adjustment device 16 that adjusts the temperature of the seawater W. The temperature sensor 12 detects the temperature of the seawater W, and the temperature adjustment device 16 adjusts the temperature of the seawater W to a temperature suitable for the marine organisms 2 and the marine plants 3. The temperature adjustment device 16 in this embodiment is a heater that heats the seawater W, but may also be equipped with a cooling device that cools the seawater W.

[0019] The cultivation system 1 is equipped with an oxygen concentration meter 17 that measures the concentration of dissolved oxygen in the seawater W, and an oxygen pump 18 that supplies oxygen into the circulating seawater W. Oxygen may be supplied into the seawater W from the stems of the marine plants 3, etc., but the amount is very small, and it is necessary to supply oxygen into the seawater W in order to cultivate the marine organisms 2. Therefore, oxygen is supplied by the oxygen pump 18 based on the oxygen concentration of the seawater W measured by the oxygen concentration meter 17, thereby maintaining the oxygen concentration required for the marine organisms 2.

[0020] The cultivation system 1 is equipped with a water level gauge 19A that measures the water level of the seawater W in the breeding tank 4 and a water level gauge 19B that measures the water level of the seawater W in the cultivation tank 5, and automatically adjusts the water levels of the seawater W in the breeding tank 4 and the cultivation tank 5 to within an appropriate range based on the water levels measured by the water level gauges 19A and 19B.

[0021] In this embodiment, the management means includes the circulation pump 7, the artificial light source, the pH measuring device 9, the salinity measuring device 10, the camera device 11, the temperature sensor 12, the storage tank 13, the storage container 14, the filtration device 15, the temperature adjustment device 16, the oxygen concentration meter 17, the oxygen pump 18, and the water level measuring devices 19A and 19B.

[0022] The cultivation system 1 also includes a server 21 that centrally manages various information and is capable of two-way wireless communication via the Internet with various devices such as a circulation pump 7, a pH meter 9, a salinity meter 10, a camera device 11, a temperature sensor 12, a storage tank 13, a storage container 14, a filtration device 15, a temperature regulator 16, an oxygen concentration meter 17, an oxygen pump 18, and water level gauges 19A and 19B.

[0023] The server 21 is capable of two-way wireless communication via the Internet with a mobile terminal 27 carried by an operator and a communication terminal 28 carried by an administrator. The server 21 is capable of communication with a plurality of mobile terminals 27 and communication terminals 28. The mobile terminal 27 is preferably one that an operator can carry with him or her when working in the breeding aquarium 4 or the cultivation aquarium 5, and is, for example, a mobile phone, a smartphone, or a tablet terminal. Meanwhile, the communication terminal 28 is mainly used by the operator or the administrator to compile and view various information of the cultivation system 1, and is, for example, a personal computer (PC). Note that a notebook PC may be used as the mobile terminal 27, and a mobile phone, a smartphone, or a tablet terminal may be used as the communication terminal 28.

[0024] As shown in Figure 2, server 21 has a control unit 22 which is a management control unit, and control unit 22 has a memory unit 23 which stores and saves various information, a judgment unit 24 which makes judgments to control various devices based on data received from various devices, a drive control unit 25 which controls the drive of various devices, and a notification information generation unit 26 which generates abnormality occurrence information to be transmitted to a mobile terminal 27 or a communication terminal 28 when an abnormality occurs in the operation of development system 1.

[0025] The memory unit 23 automatically stores and saves the hydrogen ion exponent of the seawater W received from the pH measuring instrument 9, the salinity of the seawater W received from the salinity measuring instrument 10, images of the breeding tank 4, the cultivation tank 5, etc. received from the camera device 11, the temperature of the seawater W received from the temperature sensor 12, the oxygen concentration of the seawater W received from the oxygen concentration meter 17, and the water level of the seawater W received from the water level measuring instruments 19A and 19B, together with the measurement time.

[0026] The memory unit 23 sequentially stores and saves feeding information related to the amount and time of feeding the marine organisms 2. Furthermore, the number and weight of the harvested marine organisms 2 and marine plants 3, and the number and weight of the marine organisms 2 and marine plants 3 added to the breeding tank 4 and the marine plants 3 added to the cultivation tank 5 may be stored and saved. In this embodiment, since the feeding, harvesting and addition of the marine organisms 2 and marine plants 3 are performed by an operator, after completing these operations, the operator transmits the feeding information, harvesting information and additional information to the server 21 via the mobile terminal 27 or the communication terminal 28, and stores and saves them in the memory unit 23. Note that a feeding device, a harvesting device and an adding device may be provided and controlled by the control unit 22 to automate the feeding, harvesting and adding operations, and automatically store and save the feeding information, harvesting information and additional information in the memory unit 23.

[0027] The determination unit 24 determines whether the hydrogen ion exponent (pH) value of the seawater W received from the pH measuring device 9 is within a preset range of specified values. If the determination unit 24 determines that the pH value is outside the range of specified values, a drive signal is sent from the drive control unit 25 to the storage container 14, and the hydrogen ion concentration regulator P is added from the storage container 14 to the seawater W, thereby adjusting the hydrogen ion exponent (pH) of the seawater W.

[0028] Furthermore, the determination unit 24 determines whether or not the value of the salinity of the seawater W received from the salinity measurement device 10 is within a preset range of specified values. If the determination unit 24 determines that the value is outside the range of specified values, a drive signal is sent from the drive control unit 25 to the storage tank 13 and the storage container 14, and fresh water F is introduced from the storage tank 13 and the composition M for artificial seawater is introduced from the storage container 14 into the seawater W, thereby adjusting the salinity of the seawater W. At this time, either or both of the fresh water F and the composition M for artificial seawater are introduced depending on the salinity of the seawater W.

[0029] Furthermore, the determination unit 24 determines whether the seawater W is dirty or has foreign matter mixed in, based on the images of the breeding aquarium 4 and the cultivation aquarium 5 received from the camera device 11. When the determination unit 24 determines that the seawater W is dirty or has foreign matter mixed in, the notification information generation unit 26 generates notification information notifying the presence of dirt or foreign matter in the seawater W, and transmits the notification information to the mobile terminal 27 or the communication terminal 28. When the notification information is received by the mobile terminal 27 or the communication terminal 28, the mobile terminal 27 or the communication terminal 28 notifies the notification information by image or sound. After checking the notification information, an operator investigates the cause of the dirt in the seawater W and performs work to remove the foreign matter.

[0030] Furthermore, the determination unit 24 determines whether or not the value of the temperature of the seawater W received from the temperature sensor 12 is within a preset range of specified values. If the determination unit 24 determines that the value is outside the range of specified values, a drive signal is sent from the drive control unit 25 to the temperature adjustment device 16, and the temperature of the seawater W is adjusted to be within the range of specified values.

[0031] Furthermore, the determination unit 24 determines whether or not the value of the oxygen concentration of the seawater W received from the oxygen concentration meter 17 is within a preset range of specified values. If the determination unit 24 determines that the value is outside the range of specified values, a drive signal is sent from the drive control unit 25 to the oxygen pump 18, and the oxygen concentration of the seawater W is adjusted to be within the range of specified values. Since it is mainly the marine organisms 2 that consume the oxygen in the seawater W, it is preferable that the oxygen pump 18 injects oxygen into the breeding aquarium 4. Note that, in this embodiment, the oxygen pump 18 is driven based on the value of the oxygen concentration of the seawater W received from the oxygen concentration meter 17, but the oxygen pump 18 may be driven all the time to continuously inject a predetermined amount of oxygen into the seawater W.

[0032] In addition, the determination unit 24 determines whether or not the value of the water level of the seawater W received from the water level measuring devices 19A and 19B is within a range of a preset specified value. If the determination unit 24 determines that the water level is lower than the specified value, the drive control unit 25 sends a drive signal to the storage tank 13 and the storage container 14, and fresh water F is poured from the storage tank 13 and the composition M for artificial seawater is poured from the storage container 14 into the seawater W, thereby raising the water level of the seawater W. On the other hand, if the determination unit 24 determines that the water level is higher than the specified value, the seawater W is discharged from a drainage outlet (not shown) provided in the breeding aquarium 4 or the cultivation aquarium 5, thereby lowering the water level of the seawater W. Note that if the water level can be identified, the water level may be detected by an image from the camera device 11, and the determination unit 24 may determine whether or not the water level is within the range of the specified value based on the water level.

[0033] Since the seawater W needs to be constantly circulated, the circulation pump 18 is always operating, but starts operating when it receives a drive signal from the drive control unit 25, and stops operating when it receives a stop signal. In addition, by receiving a control signal from the drive control unit 25, the drive output can be changed, and the amount and flow rate of the seawater W to be circulated can be changed.

[0034] The filtering device 15 is always in operation, but starts operating when it receives a drive signal from the drive control unit 25, and stops operating when it receives a stop signal.

[0035] The notification information generating unit 26 generates notification information notifying an abnormality when abnormal values ​​are received from the pH measuring device 9, the salinity measuring device 10, the temperature sensor 12, the oxygen concentration meter 17, and the water level measuring devices 19A and 19B, or when an abnormal color of the seawater W or the presence of a foreign object in the seawater W is determined from the video received from the camera device 11. The notification information generating unit 26 also generates abnormality occurrence information when the circulation pump 7, the pH measuring device 9, the salinity measuring device 10, the camera device 11, the temperature sensor 12, the storage tank 13, the storage container 14, the filtration device 15, the temperature adjustment device 16, the oxygen concentration meter 17, the oxygen pump 18, and the water level measuring devices 19A and 19B are not operating normally. The generated abnormality occurrence information is transmitted to a mobile terminal 27 or a communication terminal 28 that has been set in advance. The mobile terminal 27 or the communication terminal 28 that has received the abnormality occurrence information notifies the abnormality occurrence information by image or sound from its display unit (not shown) or speaker (not shown).

[0036] The marine organisms 2 are fed periodically, and feeding information such as feeding time, type and amount of food is transmitted to the server 21 by the mobile terminal 27, and the feeding information is stored in the storage unit 23. If the server 21 does not receive the feeding information for a certain period of time or more, notification information is generated by the notification information generation unit 26 and transmitted to the mobile terminal 27.

[0037] The electricity used in the cultivation system 1 is generated by a power generation method (such as photovoltaic power generation, wind power generation, hydroelectric power generation, geothermal power generation, solar heat power generation, and biomass power generation) that utilizes so-called renewable energy (sunlight, wind power generation, hydroelectric power generation, geothermal power generation, solar heat power generation, and biomass power generation) and stored in a storage battery 29. In FIG. 1, a labor-saving wind power generator is used. The power generation method may be selected according to the region or location where the cultivation system 1 is installed, and a combination of multiple power generation methods may be used. Note that it is preferable to cover the power consumption only with the power generated by the above power generation methods, but this may be supplemented with power generated by a power generation method that uses fossil fuels.

[0038] Here, the operation method of the cultivation system 1 will be described. First, a predetermined amount of seawater W is supplied to the breeding tank 4, the cultivation tank 5, and the circulation paths 6A and 6B. Next, the marine organisms 2 are housed in the breeding tank 4, and the marine plants 3 are housed in the cultivation tank 5. In this state, the circulation pump 7 is driven to circulate the seawater W. The excrement and carcasses of the marine organisms 2, uneaten food, and carbon dioxide discharged by the marine organisms 2 pass through the meshes of the net member 8 and flow from the breeding tank 4 through the circulation path 6A together with the seawater W and into the cultivation tank 5. The excrement, carcasses, and uneaten food are partially decomposed by microorganisms in the seawater W and absorbed by the marine plants 3. Therefore, the seawater W in the breeding tank 4 is purified to a certain extent by the microorganisms and the marine plants 3. In addition, carbon dioxide is absorbed by the marine plants 3, and oxygen is generated by the photosynthesis of the marine plants 3, and some of it dissolves from the marine plants 3 into the seawater W in the cultivation tank 5. The remaining excrement, carcasses, and food flow into the circulation path 6B together with seawater W. The seawater W flowing through the circulation path 6B is filtered by the filtration device 15, and the purified seawater W flows into the breeding aquarium 4.

[0039] Edible marine organisms 2 and marine plants 3 are harvested when they reach a predetermined level in the breeding tanks 4 and cultivation tanks 5. In addition, if the population of marine organisms 2 and marine plants 3 can be maintained above a certain level through natural reproduction, the population is adjusted by harvesting. If the population cannot be maintained above a certain level through natural reproduction, additional marine organisms 2 and marine plants 3 are housed and continued to be cultivated.

[0040] In Figures 3 and 4, two breeding tanks 4A, 4B and two cultivation tanks 5A, 5B are provided, and are connected by circulation paths 6A, 6B, 6C, 6D. Note that in Figures 3 and 4, the illustration of each device is omitted.

[0041] 3, the breeding aquarium 4A and the cultivation aquarium 5A are connected by a circulation path 6A, the cultivation aquarium 5A and the cultivation aquarium 5B are connected by a circulation path 6D, the cultivation aquarium 5B and the breeding aquarium 4B are connected by a circulation path 6B, and the breeding aquarium 4B and the breeding aquarium 4A are connected by a circulation path 6C. The seawater W circulates in the following order: breeding aquarium 4A → circulation path 6A → cultivation aquarium 5A → circulation path 6D → cultivation aquarium 5B → circulation path 6B → breeding aquarium 4B → circulation path 6C → breeding aquarium 4A → circulation path 6A → cultivation aquarium 5A → . . .

[0042] 4, the breeding aquarium 4A and the cultivation aquarium 5A are connected by a circulation path 6A, the breeding aquarium 5A and the breeding aquarium 4B are connected by a circulation path 6D, the breeding aquarium 4B and the cultivation aquarium 5B are connected by a circulation path 6B, and the cultivation aquarium 5B and the breeding aquarium 4A are connected by a circulation path 6C. The seawater W circulates in the following order: breeding aquarium 4A → circulation path 6A → cultivation aquarium 5A → circulation path 6D → breeding aquarium 4B → circulation path 6B → cultivation aquarium 5B → circulation path 6C → breeding aquarium 4A → circulation path 6A → cultivation aquarium 5A → ...

[0043] As described above, the cultivation system 1 of the present embodiment includes the breeding tanks 4, 4A, 4B in which the marine organisms 2 are housed together with the seawater W and cultivated, the cultivation tanks 5, 5A, 5B in which the marine plants 3 are housed together with the seawater W and cultivated, the circulation paths 6A, 6B, 6C, 6D in which the seawater W is circulated between the breeding tanks 4, 4A, 4B and the cultivation tanks 5, 5A, 5B, the management means for managing the marine organisms 2, the marine plants 3, and the seawater W, and the server 21 for automatically controlling the management means. This makes it possible to automate most of the work of cultivating the marine organisms 2 and the marine plants 3, thereby reducing the burden on the workers. Furthermore, since fewer personnel are required for operation, it is possible to reduce labor costs. Furthermore, since the seawater W is circulated, the water-saving effect is higher than that of run-off type aquaculture or open-field hydroponic agriculture, and pollution due to wastewater can be greatly reduced. Furthermore, since the feces of the marine organisms 2 and the like are used as nutrients for the marine plants 3, very little fertilizer is required for the marine plants 3.

[0044] Furthermore, in the cultivation system 1 of this embodiment, since the circulating water is seawater W, it is possible to cultivate and harvest the marine organisms 2 and marine plants 3 as food (seafood) even on land far from the sea.

[0045] In addition, the cultivation system 1 of this embodiment allows a more stable harvest of food compared to the natural world because the marine organisms 2 and marine plants 3 are edible. Therefore, it is possible to suppress a decrease in the population of the marine organisms 2 and marine plants 3 in the natural world.

[0046] Furthermore, in the cultivation system 1 of this embodiment, the control unit 22 is capable of two-way wireless communication with other mobile terminals 27 and communication terminals 28, and when an abnormality occurs, abnormality occurrence information is transmitted to the mobile terminals 27 and communication terminals 28, allowing operators and managers to quickly learn that an abnormality has occurred in the breeding tanks 4, 4A, 4B or the cultivation tanks 5, 5A, 5B. This allows for a rapid response to the abnormality, making it easier to avoid situations such as the death of the marine organisms 2 and marine plants 3.

[0047] Furthermore, the cultivation system 1 of this embodiment can be operated without emitting greenhouse gases because the electricity for driving the management means is generated using renewable energy.

[0048] In addition, by providing a storage battery for storing electricity, the cultivation system 1 of this embodiment can store electricity generated when the amount of electricity generated is high in the storage battery, even when electricity is generated using renewable energy sources, the amount of electricity generated varies depending on the time of day and the state of the natural environment, so that the cultivation system 1 can be operated stably even during times when the amount of electricity generated is low.

[0049] The present invention is not limited to the above embodiment, and various modifications are possible within the scope of the present invention. In the above embodiment, seawater W is used, but freshwater may be used to raise organisms and plants that live in freshwater. In this case, the salinity measuring device 10 and the container 14 for holding the composition M for artificial seawater are not necessary. In addition, the various devices may be installed in other positions, not limited to the positions shown in FIG. 1, as long as the devices can perform their functions. In addition, the number and arrangement of the breeding tanks, cultivation tanks, and circulation paths can be determined arbitrarily, taking into consideration the size and installation location of the cultivation system 1.
