Description

  The present invention relates to a carbon dioxide emission trading system, and more particularly, to promote carbon dioxide emission trading using a shellfish culture and carbon dioxide emission trading utilizing this immobilization method. The present invention relates to a carbon dioxide emission trading system that is activated and aims to secure profits by selling cultured shellfish and to preserve the marine environment by shellfish cultivation.

  Currently, carbon dioxide is the biggest cause of global warming. For this reason, reduction of carbon dioxide emissions was discussed internationally and an agreement was reached in the form of the Kyoto Protocol. The Kyoto Protocol was adopted by COP3 (3rd Conference of the Parties to the Framework Convention on Climate Change, in Kyoto) to achieve the objective of the Framework Convention on Climate Change to stabilize the concentration of greenhouse gases in the atmosphere. Therefore, it obligates developed countries to reduce greenhouse gas emissions by a certain value (Japan 6%, US 7%, EU 8%) from 2008 to 2012 compared to 1990 levels.

  Three mechanisms of “Clean Development Mechanism (CDM)”, “Joint Implementation (JI)”, and “Emissions Trading (ET)” as flexible measures when the target cannot be achieved by domestic measures in the Kyoto Protocol It is possible to carry out carbon dioxide reduction projects in other countries and take them home.

  Emission trading system is a system that trades carbon dioxide emissions as securities, and countries, companies, etc. that have achieved the reduction target try to emit carbon dioxide beyond the target with the amount of reduction exceeding the reduction target as emission credit. It is a system for achieving the global target for CO2 reduction in each country by selling the product to countries or companies.

  In other words, since the total amount of carbon dioxide emission is determined, if the carbon dioxide is discharged in excess of the allocated amount, it is necessary to obtain a carbon dioxide emission right commensurate with the excess amount. Obligation to obtain carbon dioxide emission right according to the amount of carbon dioxide to be done.

  On the other hand, if the amount of carbon dioxide emission credits acquired is reduced by developing carbon dioxide fixation technology, surplus carbon dioxide emission rights can be sold, and consumers and suppliers can Because it exists, trading of carbon dioxide emission rights is established here.

  Conventionally, regarding trading of carbon dioxide emission rights, as disclosed in Patent Documents 1 and 2, a trading form targeting power generation has been proposed. Patent Document 1 buys and sells carbon dioxide emission rights based on solar cell power generation. Patent Document 2 shows that carbon dioxide emission rights created by alternative power generation means that replace fossil fuel-based power generation can be fixed by a third party that can objectively evaluate carbon dioxide emissions. Is evaluated as a contribution, and a certificate is issued and distributed in the market.

  Patent Document 3 discloses a carbon dioxide emission trading system based on carbon dioxide fixation technology using the ocean. Specifically, securing a certain sea area for carbon dioxide absorption and fixation, by nurturing and protecting coral reefs, by securing and developing sea areas for growing various shellfish, by securing and developing seaweed growing sea areas Technology type of carbon dioxide fixation technology to be developed using the ocean, such as by securing and developing beaches for cultivating mangroves, evaluation points, database storage area consisting of available area and area, carbon dioxide The input receiving unit for the emission amount, the input carbon dioxide emission amount and the data stored in the database storage unit obtain the product of the area and the evaluation point, and the operation comparison means for comparing the input amount and the product. A management device for a carbon dioxide emission trading system comprising display means for selecting and displaying a technology larger than the input amount is shown.

  However, the carbon dioxide fixation technology disclosed in Patent Document 3 includes technology that can be evaluated from the viewpoint of environmental conservation, but it is difficult to calculate and evaluate a specific amount of carbon dioxide fixation, and carbon dioxide emission is also possible. Although the rights were created, there were some places where the investment effect was low, and it was virtually impossible to enter other than public institutions such as national and local governments.

  By the way, Japan is a country blessed with abundant fishery resources with long coastlines, many rivers and lakes, and fishery has occupied a large position as an industry since ancient times. Especially for sandy beaches and tidal flats developed near the river mouth, bivalve resources were a source of income as a special product. However, environmental pollution in rivers, lakes, and tidal flats, the disappearance of fishing grounds due to land reclamation, and overfishing As a result, the amount of resources has decreased significantly.

  For this reason, in place of the natural resource harvesting type fishery, the production of shellfish by aquaculture has been studied in recent years and some have been carried out.

  For example, as a method for culturing so-called superficial bivalves such as oysters, scallops, and pearl oysters that inhabit seawater and grow on the substrate, they can be placed in a net cage in addition to the ground culture method. Or a seedling seedling adhering to a shell is cultivated in water without being covered with a net or the like.

  In addition, for buried bivalves, it is considered that a sand bed that shellfish should infiltrate is generally necessary because it is buried in sand mud, and no aquaculture method that hangs in water has been applied. As a method for aquaculture, land-based aquaculture is being studied.

  However, due to the recent inflow of domestic wastewater, agricultural wastewater, industrial wastewater, etc., the eutrophication of the aquaculture area has progressed, and an anoxic water mass is generated near the bottom, threatening the habitat of shellfish. The fishery harvest by such aquaculture has not improved, and it has fallen into a situation that impairs the willingness of workers to work.

  Recently, in connection with the global warming problem due to the increase in carbon dioxide emissions mentioned above, the carbon dioxide balance by shellfish has been studied, while shellfish emit carbon dioxide by breathing, excretion, decomposition, egg laying, etc. It is reported that carbon dioxide is immobilized by shell formation and feeding, and the carbon balance is slightly larger on the immobilization side.

For this reason, an efficient and stable shellfish culture method has been developed, and the carbon dioxide fixation amount of such shellfish can be clearly calculated and evaluated, and carbon dioxide emission trading based on the fixation amount is possible. If the system can be established, fishermen will be able to obtain both the profits from the sale of harvested shellfish and the profits from carbon dioxide emissions trading, and improve the fishermen's income and willingness to work, It will also contribute to solving the problem of global warming.

Further, since the aquaculture method has a very high aquaculture efficiency of shellfish, the farmer can enjoy an increase in profits by selling cultured shellfish and selling carbon dioxide emission rights.

  Hereinafter, the present invention will be specifically described based on specific embodiments. The present invention provides a shellfish farmer who cultivates shellfish and sells carbon dioxide emission rights according to the harvest amount, and an emission credit purchaser who desires to purchase the carbon dioxide emission rights sold by the shellfish farmer. It is a carbon dioxide emission trading system that trades in between.

  As described above, shellfish discharge carbon dioxide by breathing, excretion, decomposition, egg laying, etc., while carbon dioxide is fixed by shell formation and feeding, and its carbon balance is slightly larger on the fixed side It is known as a thing, but this is a story in the life cycle of shellfish in nature. If you survive by harvesting and consuming shellfish, etc., you can obtain stable immobilized carbon as a shell, and considering that the carbon balance during growth is larger on the immobilized side, It has been found that culturing shellfish and harvesting it is extremely effective as a carbon dioxide immobilization technique, and the immobilization amount can be calculated relatively easily from the harvest amount. Based on such knowledge, the present inventors have constructed a system that can smoothly trade carbon dioxide emission rights by shellfish culture.

  FIG. 1 shows an example of a carbon dioxide emission trading system of the present invention. In this system, terminal devices 10 of a plurality of shellfish farmers that oxidize into a trading system, and a terminal device 20 of a plurality of environmentally conscious industry companies, emission purchasers of nations, etc. are connected via a network 30 to carbon oxide. It is connected to a transaction server 40 provided in an emission credit exchange.

  The network 30 may be the Internet or a dedicated line network system, but is preferably a dedicated line from the viewpoint of security.

  Each of the terminal devices 10 and 20 includes, for example, a general-purpose device such as a personal computer or a dedicated terminal device. The communication device connects to the network 30, an input device such as a keyboard and a mouse, and a display device such as a display. At least.

  Furthermore, the terminal device preferably includes an output unit such as a printer and a read / write unit for an identifier given to a shellfish farmer or a purchaser of emission rights. Specific examples of identifiers given to shellfish farmers or emission right purchasers include, for example, magnetic cards, IC cards, flash memory cards, IC tags, and the like. It is a writer.

  Access from each terminal device 10 and 20 to the trading server of the carbon dioxide emission trading system can be freely granted without any restrictions to shellfish farmers and emission credit buyers who wish to participate. In order to improve the safety and reliability of transactions, registration, registration and application of information such as name, location, telephone number, nickname or abbreviation used for transactions, payment or receipt methods, etc. are approved in advance. It is desirable to adopt a participant registration system in which an identification number, a password, etc. are given to a person who can access by entering these identification number, password, etc. Furthermore, if identification information such as the registrant's identification number is stored in the identifier as described above, and access to the identifier (and input of a password) is required, access by an unauthorized third party The possibility of access can be eliminated, and the safety of transactions can be increased. The password is not limited to one, but the second, third,. It is also possible to improve security by using a plurality of passwords such as.

  FIG. 2 is a block diagram showing the configuration of the transaction server 40 in one embodiment of the present invention. The transaction server 40 in this embodiment includes an input receiving unit 41, a database storage unit 42, a calculation unit 43, a sale data storage unit 44, a purchase data storage unit 45, and a data processing unit 46.

  The database storage unit 42 stores data on the amount of carbon dioxide immobilized by cultured shellfish. The data on the amount of carbon dioxide immobilized is based on at least the type of cultured shellfish and the method of cultivation. The data to be entered in this database is important to determine whether the harvest of the cultured shellfish is in a state where carbon dioxide fixation technology is applicable, and to determine the basic unit when it is determined that it is possible. In making a decision, it is important to improve the credibility of the technology by evaluating it with a fair third party. In addition, it is a carbon dioxide fixation technology using a living body called shellfish, and even if it is the same species and the same aquaculture technology, the basic unit may vary depending on the situation of the aquaculture area, harvest season, etc. It is preferable that the calculation of the fixed amount of carbon dioxide is made precise by finely setting for each of these variable factors.

  The method for calculating the basic unit of carbon dioxide fixation by cultured shellfish will be determined by a fair third-party organization or public organization, and is not particularly mentioned in this specification. Examining and calculating shell weight, amount of ingredients, etc. with respect to harvested cultured shellfish, based on the obtained values, the length of the culture period, the respiration during the culture (survival) period for each culture method, Carbon dioxide emissions due to excretion, etc., carbon balance of carbon dioxide fixation due to feeding, shellfish survival rate during the cultivation period, the weight of the shell due to differences in the conditions of the aquaculture area, harvest season, etc. It is thought that the function equation for determining the amount of carbon dioxide fixation is determined after studying and investigating the influence on the amount of components, etc., and parameterizing it.

  In addition, as mentioned above, when the shellfish traders and emission credit purchasers participating in the trading system are pre-registered, the registration information data of these shellfish traders and emission credit purchasers shall be an identification number, password, etc. It is necessary to store a database constructed in association with each other, and the database storage unit 42 that stores data on the amount of carbon dioxide immobilized by cultured shellfish can be used as the accommodation destination. Of course, a database storage unit for registering registration information databases of shellfish farmers and emission right purchasers may be provided separately.

  This registered information database of shellfish farmers and emission rights purchasers tries to access the transaction server 40 by inputting identification numbers or identifiers and passwords from the terminal devices 10 and 20 by the shellfish farmers and emission rights purchasers. The data processing unit 45 grants access to the shellfish associated with these identification number or identifier and password when there is data whose identification number or identifier and password match. The trader and the emission credit purchaser are authorized as accessors, and the information of the shellfish trader and the emission credit purchaser is associated with the input data input to the input receiving unit 41. On the other hand, if there is no data that matches both the identification number or the identifier and the password, the access is denied, and the fact that there is no matching data is displayed on each terminal device 10 and 20.

  The input receiving unit 41 receives input data from the terminal device 10 of the shellfish farmer connected to the transaction server 40 via the network 30 and input data from the terminal device 20 of the emission right purchaser.

  The input data that the input receiving unit 41 receives from the terminal device 10 of the shellfish farmer and the terminal device 20 of the emission right purchaser depends on the trading method adopted by the data processing unit 46 described later.

  For example, in the first embodiment in which the unit price per unit quantity of carbon dioxide emission rights is fixed and traded, at least the amount of cultured shellfish harvested from the terminal device 10 of the shellfish farmer, the terminal of the emission right purchaser It suffices if it is set so that the desired purchase amount of carbon dioxide emission rights from the apparatus 20 can be input. For example, an operator who accesses from each terminal device via a network is provided with a frame for inputting these numerical values, and the numerical values are input with a keyboard or the like.

  Regarding the factors that determine the basic unit of carbon dioxide fixation, such as the type of shellfish cultivated by shellfish farmers and the cultivation method, the shellfish farmers participating in the transaction system shall be pre-registered as described above. In this case, it is possible to store these factors in the database as registered information in advance, but the input receiving unit 41 has a frame for inputting these factor information and is input for each transaction. It is also possible to adopt a form in which

  Further, in another embodiment in which the unit price per unit quantity of carbon dioxide emission rights is not fixed and traded as a floating market price, for example, from the terminal device 10 of the shellfish farmer, the emission rights together with the harvested amount of the cultured shellfish. It is possible to set the desired unit price for sale and the emission credit purchase desired unit price together with the desired purchase amount from the terminal device 20 of the emission credit purchaser.

  Further, in the embodiment in which the unit price per unit quantity of carbon dioxide emission rights is traded in the form of a floating market (auction), for example, from the terminal device 10 of the shellfish farmer, the yield and discharge of cultured shellfish It is possible to set the input of the desired right sale minimum unit price, the maximum desired sale unit price, the desired sale period, and the desired purchase price from the terminal device 20 of the emission right purchaser. In this case, it is indispensable to input the harvest amount of the cultured shellfish from the terminal device 10 of the shellfish farmer, but other inputs such as the minimum unit price for selling emission credits, the maximum unit price for selling, the desired unit selling period, etc. It can be any as well as in known discount systems.

  The input data that the input receiving unit 41 receives from the terminal device 10 of the shellfish farmer and the terminal device 20 of the emission right purchaser is not limited to that in the above-exemplified embodiment, and is a data processing unit. In the buying and selling method adopted by 46, any method may be used as long as it satisfies the conditions required or added for executing the buying and selling.

  In addition, regarding the harvested amount of the cultured shellfish entered by the shellfish farmer, the harvested amount is certified by a public institution or the like in order to prevent arbitrary input or erroneous input by the shellfish farmer and to enhance its credibility. It is desirable to have a shape.

  For example, in a preferred embodiment, as shown in FIG. 1, the transaction system further includes a yield authentication terminal device 50 disposed in a carbon dioxide emission trading organization or a trader certified by the trading organization. The harvest amount authentication terminal device 50 is provided when the shellfish farmer delivers the harvested shellfish to the carbon dioxide emission trading agency or a dealer certified by the trading agency. It is assumed that a yield code whose amount is proved by a predetermined encoding is issued. The harvest amount authentication terminal device 50 sends the issued harvest amount code data to the transaction server 40 via the network 30, and the transaction server 40 transmits the received harvest amount code data to, for example, the database storage unit 42. In addition to the issued yield code database stored in an appropriate storage unit such as It is not always necessary to input the data of the issued harvest code to the transaction server, and the harvest authentication terminal device 50 that has issued the harvest code for preventing information leakage or the like. The information is sent from the carbon dioxide emission credit trading institution or the business operator certified by the trading institution to the institution or department in which the business server 40 is installed by mail or the like, and the information is directly sent to the business server 40. It is also possible to input.

  The input receiving unit 41 inputs the harvested amount of the cultured shellfish from the terminal device 10 of the shellfish farmer by using the harvested amount code (an aspect in which both the harvested amount code and the numerical value of the harvested amount are input). ) Accept and check against the issued harvest code database existing on the transaction server 40 to determine whether or not the data is authentic, and input the data if it is authentic Accept.

  In addition, as a method of making the harvest amount of the cultured shellfish input by the shellfish farmer into a form certified by a public institution or the like, it is limited to the method using the harvest amount authentication terminal device 50 as described above. Instead, for example, a system may be adopted in which the harvest amount of the cultured shellfish input by the shellfish farmer is temporarily accepted, and this numerical value is collated with a related organization such as a public organization and then authenticated.

  The calculation unit 43 receives the data of the cultured shellfish harvest amount input from the terminal device 10 of the shellfish farmer to the input receiving unit 41 and the carbon dioxide fixation amount by the cultured shellfish stored in the database storage unit 42 (original From the unit, the amount of carbon dioxide immobilized according to the input harvest is obtained by calculating, for example, the product of both. In addition, in order to retrieve and extract data used for the calculation from the database of the amount of carbon dioxide immobilized by the cultured shellfish stored in the database storage section 42, as described above, input from the terminal device 10 of the shellfish farmer When the factor information input together with the harvested amount of the cultured shellfish in the reception unit 41, or when the shellfish farmer is pre-registered as described above, the factor information existing in the farmer registered information data is referred to. The

  The sale data storage unit 44 stores the data result of the carbon dioxide immobilization amount calculated by the calculation unit 43 as described above in association with the shellfish farmer who performed the input. Note that, as described above, the input receiving unit 41 may include input data other than the harvested amount of cultured shellfish depending on the trading method adopted by the data processing unit 46 to be described later. Stores the input data other than the harvest amount in association with the shellfish farmer who made the input.

  For example, in the embodiment in which trading is performed as a floating market as described above, the data on the desired unit price for selling emission credits input together with the amount of cultured shellfish harvested is also traded in the form of a bargain sale (auction) as a floating market. In the embodiment, the data of the emission right sale desired minimum unit price, the sale desired maximum unit price, and the desired sale period, which are input together with the yield of the cultured shellfish, are stored together with the carbon dioxide fixation amount data.

  In this way, for each shellfish farmer as a selling method, data necessary for the sales transaction including the carbon dioxide fixation amount is stored in the sale data storage unit 44.

  On the other hand, the purchase data storage unit 45 stores the input data that the input receiving unit 41 receives from the terminal device 20 of the emission credit purchaser in association with the emission credit purchaser who made the input.

  The input receiving unit 41 may include input data received from the purchaser of emission credits other than the desired purchase amount depending on the trading method adopted by the data processing unit 46 described later. The input data other than the desired purchase amount is also stored in association with the purchase requester who made the input.

  For example, in the embodiment in which buying and selling is performed as a floating market as described above, data on the emission unit purchase desired unit price input together with the desired purchase amount is stored.

  In this way, the purchase data storage unit 45 stores the data necessary for the sales transaction including the desired purchase amount with respect to the purchaser of the emission credit as the purchaser.

  In the embodiment in which buying and selling is performed as a floating market price as described above, the input data received by the input receiving unit 41 from the terminal device 20 of the purchase applicant may be only the desired purchase amount. The purchase data storage unit 45 as described above is not particularly provided, and at least one data item that can identify the purchase desired amount and the purchase applicant who has input the purchase amount, such as a nickname, a name, and an identification number of the purchase applicant. It is also possible to adopt a method in which these are directly recorded in each sale data stored in the sale data storage unit 44.

  The data processing unit 46 establishes a transaction with the sale data existing in the sale data storage unit 44 and the purchase data existing in the purchase data storage unit 45.

  Various modes can be used as a transaction method adopted by the data processing unit 46. For example, in an embodiment in which the unit price per unit quantity of carbon dioxide emission rights is fixed and sold, each sale data in the sale database in the sale data storage unit 44 and each purchase data in the purchase data storage unit 45 When purchase data is simply contrasted and there is data having the same amount between both databases, a mode in which the sale data and purchase data are linked to automatically establish a sale can be adopted. In this comparison, it is desirable that the comparison be performed in accordance with the registration order of the data so that the transaction is established from the old side of registration.

  In addition, it is assumed that shellfish farmers will be selling as part of this transaction system, while companies such as eco-friendly industries, nations, etc. are assumed as buying methods, and the amount on the sales data side will be the amount on the purchase data side. In general, when it is considered that matching of the one-to-one data as described above is relatively difficult, one purchase data existing in the purchase data storage unit 45 is small. A mode in which a plurality of pieces of sales data existing in the sale data storage unit 44 are accumulated with respect to (in some cases, the total amount of a plurality of purchase data), and a transaction is automatically established by matching the amounts. It is also possible to adopt. Even in this case, it is desirable that the accumulation is performed in the order of registration of data in principle, and a new data is promoted and combined only when there is no coincidence with the purchase data.

  Of course, on the contrary, each amount on the sales data side is generally larger than each amount on the purchase data side, and it is considered that it is relatively difficult to match one-to-one data. In the case where the purchase data is stored, a plurality of pieces of purchase data existing in the purchase data storage unit 45 are integrated with respect to one sale data existing in the sale data storage unit 44 (in some cases, a total amount of a plurality of sales data). Thus, it is possible to adopt a mode in which the amount is matched to automatically establish a transaction.

  In another embodiment in which the unit price per unit quantity of carbon dioxide emission rights is not fixed and sold as a floating market price, each sale data in the sale database in the sale data storage unit 44 and the purchase data storage unit 45 are also sold. Each purchase data in the purchase database is compared, and if there is data with the same amount and desired unit price between the two databases, the sale data and purchase data are linked to automatically establish a sale. be able to. In this case as well, if it is difficult to match one-to-one quantitative data, a plurality of data on the selling side and / or the buying side with the same desired unit price is accumulated and the amount is matched. Can be adopted.

  Further, the transaction may be established even when the desired unit price presented by the selling method is smaller than the desired unit price presented by the buying method indicated in the purchase data already existing in the purchase database. In this case, generally, the desired unit price presented by the seller is the transaction unit price.

  Next, in an embodiment in which the transaction method employed by the data processing unit 46 is a floating sale (auction) format, the data processing unit 46 takes a slightly different form from that described above. That is, each data read from the sale database in the sale data storage unit 44 is displayed on each terminal device (at least the terminal device 20 on the purchaser side) connected via the network 30 during the designated desired sale period. For each display data, the desired purchase amount data received by the input receiving unit 41 from the terminal device 20 of the emission credit purchaser during the sale period is the minimum that can identify the purchaser who has input it. Along with one data item, it is recorded directly on each sale data stored in the sale data storage unit 44, the data is updated, and the purchaser who entered the maximum amount at the end of the desired sale period The sale is concluded with. In addition, in the middle of the desired sale period, if purchase desired amount data exceeding the maximum desired unit price for sale is entered in the sale data, the sale is concluded with the purchaser who made the entry, and after that point Stop accepting input of the desired purchase amount from the terminal device 20 of the emission credit purchaser to the input accepting unit 41.

  When the data processing unit 46 establishes the sale as described above, the data processing unit 46 notifies the seller and the buyer related to the transaction that the transaction has been established. For example, the display data and the like are sent to the terminal device 10 of the seller-side aquaculture company and the buyer-side purchaser's terminal device 20 related to the transaction. This notification can be made by sending e-mails to sellers and buyers' e-mail addresses registered in advance. Alternatively, a notice in a predetermined format can be created and output to relevant parties. May be directed to the operator of the transaction server.

  Then, the data processing unit 46 deletes the data on the seller side and the data on the buyer side where the transaction has been established from the sale database in the sale data storage unit 44 and the purchase database in the purchase data storage unit 45, or performs processing. Each database is updated by making a record of completion or setting a flag to prepare for a new transaction after the fact.

  In addition, when the transaction is established as described above, the transaction server charges the emission credit purchaser based on the sale result established in the data processing unit, while the shellfish that has sold the carbon dioxide emission rights Instruct the farmer to remit at least a portion of the charges collected from the emission purchaser. Such billing processing can be executed by the data processing unit 46, but a data processing unit for billing processing may be provided separately. In addition, settlement can be automatically performed by general electronic settlement.

  As mentioned above, the configuration of the carbon dioxide emission trading system according to the present invention and the flow of transactions in the system have been described taking some embodiments as examples, but the present invention is not limited to these illustrated embodiments. is not.

  In addition, in the carbon dioxide emission trading system according to the present invention, the shellfish traders participating in the system as a seller are not particularly limited to the types of shellfish handled, the culture method, etc. Or, of course, you can join the system as a company, for example, if there are unions or groups that collectively manage the harvest of the same kind of shellfish, the cultivation of multiple individuals or companies in the cultivation method, etc. In its name, it is possible to join the system of the present invention as a shellfish farmer.

  As described above, the shellfish farmers participating in the system are not particularly limited to the type of shellfish handled, the culture method, etc., for example, so-called superficial types such as oysters, scallops, pearl oysters, etc. Bivalve land culture method, culture method that puts seedlings in shellfish, or hangs seedlings attached to shellfish directly in the water without covering with net, etc., or seawater embedment such as clams, clams, crabs Participation methods such as bivalves and swordfish that carry out freshwater or brackish buried bivalve land culture methods can also participate, but in the local culture method, the larvae released in the aquaculture area and harvested aquaculture It is difficult to clarify the ratio with shellfish, the cultivation period, the survival rate of shellfish during cultivation, etc., and as a result, the dioxide produced by cultured shellfish, which is necessary on the system of the present invention, is required. Because of the calculation of the basic unit containing fixed amounts can become a problem in terms of authenticity for it and the resulting value is difficult to be assumed, it is believed that involve certain difficulties in their participation.

  In contrast, the method for culturing buried bivalves separately invented by the present inventors makes it easy and clear to grasp the ratio of juveniles to harvested cultured shellfish, the cultivation period, the survival rate of shellfish during cultivation, etc. Thus, the calculation of the basic unit of the amount of carbon dioxide immobilized by the cultured shells required on the system of the present invention is easy and highly reliable. In addition, since the aquaculture can be performed efficiently in a short aquaculture period and with a high survival rate, the efficiency and amount of carbon dioxide fixation are also excellent. Therefore, the method for cultivating this buried bivalve has an aspect that it is very excellent as a method for fixing carbon dioxide, and the cultivator performing the method cultivates the carbon dioxide emission rights of the present invention. Particularly preferred as a participant in a trading system.

  Hereinafter, a method for cultivating the buried bivalve or a method for fixing carbon dioxide will be described. The method for cultivating buried bivalves or carbon dioxide fixation is characterized in that juvenile bivalve molluscs are housed in a water-permeable container and cultured while being suspended in the water of the breeding ground. To do.

  The target shellfish is not particularly limited as long as it is a buried bivalve and can be applied to various shellfish, but a buried bivalve that inhabits brackish water and freshwater is particularly preferred. Become.

  Specific examples of the buried bivalve inhabiting brackish water and fresh water include, for example, Yamajijijimi, Setashijimi, Masajimi and the like. These rainbow trouts have good carbon dioxide immobilization even in the balance of carbon dioxide, and are excellent as an aquaculture target for carbon dioxide immobilization.

  In addition to these edible bivalves that are edible, the number of individuals increases from the standpoint of protecting the natural environment, for example, they become spawning shellfish for fish such as sea lions, and the number of inhabitants has decreased due to environmental destruction. Other shells that are required, for example, mussel, mussel, taiga and other shellfish, crow shellfish, mencarus shellfish, mussel shell, pine shellfish shell, scallop shellfish, scallop shellfish, Yokohama clam shellfish, catfish shellfish, shellfish shellfish, basin Shellfish, Sasanoha and Tongarisa Sanoha can also be used.

  Of course, it is not limited to those exemplified above. For example, in addition to the shells exemplified above in Japan, the target is buried bivalve shellfish inhabiting brackish water and freshwater in other countries. You can also.

  In addition, as seawater bivalves, for example, clams such as clams, ginseng clams, oyster clams, clams such as clams, peacock clams, clams, funnels such as scallops, sugar mussels, clams, mussels, mussels, lobster mussels, etc. It is also possible to use mussels, oysters, snails, milk mussels, shrimp mussels, etc. as targets.

  In the present invention, such buried bivalve larvae are prepared by sampling or separately cultured. Although it differs depending on the type of shellfish, for example, as for swordfish, juvenile shellfish of about 3 to 7 months of age or about 2 to 5 mm in diameter can be used. In addition, it is also possible to cultivate shellfish grown more than that for further growth.

  Moreover, as a farm where the farming method of the present invention is carried out, a natural place such as a lake, a swamp, a river, or a sea area where the shellfish originally live can be used. In addition, it is also possible to use an artificially made outdoor pond or pool, or a smaller outdoor or indoor water tank. In general, it is preferable to use natural lakes, swamps, rivers, or sea areas from an economic point of view, but if you manage feeding, water temperature, water quality, water flow, etc., use artificial farms. It is also desirable from the viewpoint of effective use of land.

Next, the water-permeable container for accommodating such buried bivalve larvae is not particularly limited as long as it has sufficient water permeability and can stably hold shellfish in water at the farm. Although not intended, for example, various nets and moss can be used. Although it does not specifically limit even if it is the magnitude | size, For example, the thing whose internal volume becomes about 1-2 m < ³ > can be illustrated as a preferable thing from the workability | operativity at the time of culture being easy.

  As a method for arranging the buried bivalve in a water-permeable container, it is possible to place it flat in a container where the shell does not overlap too much, or to arrange it in a lump with considerable overlap, In any case, it is desirable to hold the shellfish in a state where it can move freely to some extent.

  In addition, when using a natural place such as a lake, pond, swamp, river, or sea area as a farm, the water-permeable container may be damaged by obstacles such as driftwood and garbage floating in the water area. For example, a fence having a relatively strong strength, for example, an enclosure having at least a rigid material such as metal, plastic, or wood as a frame is used as a protective exterior body. It is desirable to have a double or multiple structure, such as arranging a plurality of nets, shells and other breathable inner containers.

  In addition, when an exterior body is provided in this way, this exterior body can be used as a support body for the vibration equipment when a vibration equipment as described later is provided. Further, a stress substance such as a photocatalyst or a low-level radioactive substance can be put in a container or the like, and the container or the like can be attached to the exterior body.

  A method for holding such a water-permeable container in the water of the farm is not particularly limited. For example, as schematically shown in FIG. 3, several floats 111 are floated on the water surface 110 of the farm. The floating element 111 is fixed to the bottom wall 113 of the aquaculture farm by being anchored or locked from the quay wall 114, and the breathable container 116 is submerged into the water from the support line 115 stretched between the floating elements. This can be done by drooping.

  In the embodiment shown in this figure, the breathable container 116 has a double structure having the breathable inner container 116A for shellfish housing and the protective outer package 116B surrounding the outside as described above. ing.

  Moreover, when culturing in an artificial pool, a water tank, or the like that does not have a mud sand floor at the bottom, it is possible to simply take a form in which a breathable container is submerged in water.

  The underwater position for holding the water-permeable container is not particularly limited as long as plankton or organic suspension is sufficiently deep to serve as food for shellfish contained in the water-permeable container. For example, the position of the shell contained in the water-permeable container can be held in a water area having a depth of about 10 cm to 250 cm, although it depends to some extent on the topography, its type, and the type of shellfish.

  As described above, the aquaculture method can be carried out by storing the buried bivalve larvae in a water-permeable container and holding them in water for a predetermined period, for example, about 1 to 2 years. From the viewpoint of further increasing the degree, it is preferable to apply stress treatment to the shellfish.

  Examples of the stress treatment include at least one treatment selected from an ultraviolet irradiation treatment, a surface tension fluctuation treatment, a water pressure fluctuation treatment, a trace radiation irradiation treatment, and a vibration treatment. In the culture method of the present invention, the degree of growth of the buried bivalve can be rapidly accelerated by applying one or more stress treatments to the shellfish. In addition, when giving several stress processing, the combination is free. The plurality of stress treatments may be performed simultaneously or alternately.

  The ultraviolet irradiation treatment can be performed by holding the position of the buried bivalve accommodated in the water-permeable container in a water area having a depth of about 10 cm to 250 cm that is not so deep from the water surface. By holding in this position, the shellfish can be exposed to more ultraviolet rays.

  Surface tension fluctuation treatment is a treatment that changes the surface tension of water around the shell. Specifically, a photocatalyst or low-level radioactive compound is provided around the shell, and the action of the photocatalyst or low-level radioactive compound. The surface tension of the water around the shell can be changed by the hydroxy radical (OH radical) generated by.

  As the photocatalyst, a known photocatalyst represented by, for example, titanium oxide or a composite compound thereof, for example, Japanese Patent Application Laid-Open No. 10-34143 or Japanese Patent Application Laid-Open No. 2003-335523 can be applied. Moreover, as a low level radioactive compound, the processing material etc. which generate | occur | produce the radiation of the grade which does not have a bad influence on a living organism, for example, natural uranium (for example, extract | collected with a Japanese puppet bowl), etc. can be used. This processed material acts as a radon-generating ceramic. Specifically, it changes from uranium (U) to radium (Ra), and from this radium, it comes out as radon (Rn) gas. Also, various low-level radioactive compounds other than radon can be preferably applied.

  The low-level radioactive compound acts to change the surface tension of water by generating hydroxy radicals as described above. However, even if the effect of changing the surface tension is small, only the generated hydroxy radicals can cause shells. Can give stress. Therefore, the stress treatment using the low level radioactive compound can also be referred to as a trace radiation irradiation treatment.

  These photocatalysts and low-level radioactive compounds are put in a container or the like, and the shell can be subjected to surface tension variation treatment or trace radiation irradiation treatment by attaching the container to a water-based container or attaching to the exterior body. .

  The water pressure fluctuation treatment is performed by stressing the shellfish by, for example, periodically changing the position of the shell in the water-permeable container up and down to change the water pressure or artificially changing the water pressure in an artificial water tank. Can be given.

  Examples of the vibration treatment include a method of applying vibration to the shell by performing aeration from the vicinity of the water-permeable container to the inside of the container. For example, in the embodiment shown in FIG. 3, a bubbling device 117 is installed near the bottom surface of the protective exterior body 116 </ b> B. The bubbling device 117 includes an air supply pump installed on the quay wall 114. An air supply line 119 extended from 118 is connected, and aeration can be performed on the air-permeable inner container 116A by the pressure-fed air.

  The device mechanism for aeration, which is an example of vibration processing, is not limited to that illustrated in FIG. 3 and can take various forms, but can generate fine microbubbles. It is desirable that Of course, aeration can be performed continuously, but intermittently, for example, repeats operation and pause every 30 minutes to 1 hour, or operates only during a certain time of day or night, and rests for the remaining time. It is also possible to take a form such as.

  As a bubbling device 117 for performing aeration, for example, a device in which a porous body such as a sponge, an air stone, or a porous ceramic is attached to the tip of an air supply line, an ultrasonic vibrator, a venturi tube, or the like is used. An example of a configuration in which a gas-liquid two-phase flow is sheared hydrodynamically can be exemplified, but a method using an ultrasonic vibrator is desirable from the viewpoint of generating finer bubbles.

  When performing aeration, for example, an ozone generator using an ultraviolet lamp or the like may be attached in the middle of an air supply line sent to a bubbling device, and ozone may be included in the gas to be aerated. By containing ozone having a bactericidal action, the shellfish can be stressed, and as a result, the growth of the shellfish can be remarkably enhanced.

  By applying stress to the shells as described above, the shells grow significantly faster to resist the stress, the shells become thicker and larger in size.

  The aquaculture period by the aquaculture method is not particularly limited, and may be performed until the shellfish to be cultivated grow to a sufficient size. For example, a conventional aquaculture method for burying and growing in sand mud In the case of Yamatoshijimi, which took about 3 to 4 years to grow to a size that can be shipped as a product, even in the cultivation period of about 2 years, which is sufficiently shorter than this, It is possible to grow it to be sufficiently larger than 3-4 years. In addition, in the conventional method, the growth rate was moderate when the shell length was grown to a certain value or more. However, in this method, the growth rate was not substantially reduced after this size was reached. By continuing the culture, larger shellfish can be obtained.

  The results obtained by the present inventors actually implementing this aquaculture method for Yamatoshijimi are as follows.

(Culture example 1)
2kg Koda, 2576 Koda, Inashiki-shi, Ibaraki Prefecture, 1 kg of Yamatojimi larvae with a diameter of about 5 mm collected in a culture pond owned by Oko Pearl Co., Ltd. is placed in a container made of wire mesh with a mesh of 1 mm. In an aquaculture farm of about 2.5 m, it was kept under water at a depth of 0.1 to 1 m below the surface of the water, cultured, and regularly observed for shell growth. The farm was the Shintone River, 2576 Koda, Inashiki City, Ibaraki Prefecture, and the start of the aquaculture was April 2006. As a result, the average diameter of the shellfish was about 15 mm in 10 months from the start of the cultivation, and the total weight was about 5 kg. In addition, no particular illnesses or deaths were observed during the cultivation period.

(Comparative farming example 1)
2576 Koda, Inadaki-shi, Ibaraki Prefecture, 1 kg of Yamatojimi larvae with a diameter of about 5 mm collected in a culture pond owned by Oko Pearl Co., Ltd. is cultured in an artificial pool of 40 cm depth owned by Oko Pearl Co., Ltd. went. The start of aquaculture was April 2006. In this artificial pool, sand and mud were laid 15 cm thick, and larvae were buried in the sand and mud for cultivation. As a result, the average diameter of the shellfish was about 7 mm within 10 months from the start of the cultivation, and the total weight was about 1.5 kg.
