Technical Field

[0001] The present invention relates to a program and an information processing apparatus that display quantity information corresponding to the amount of environmental DNA of aquatic organisms together with a map image.

Background Art

[0002] Patent Document 1 states that in order to accurately conduct ecological surveys of freshwater environments such as rivers using environmental DNA (eDNA) / environmental RNA (eRNA) metabarcoding analysis, it is very important to estimate false positives and take measures to reduce their effects, and discloses a method for ecological surveys of fish in freshwater environments. The method for ecological surveys of fish uses the following method. This method is a method for estimating the contamination state of nucleic acids of fish derived from outside the freshwater environment in the freshwater environment, using the nucleic acid amounts of environmental DNA and environmental RNA contained in domestic sewage or influent water to a sewage treatment plant and the effluent water from the sewage treatment plant. The method for ecological surveys of fish includes the following first, second, and third procedures. The first procedure comprehensively quantifies the amount of nucleic acids derived from fish species in a sample collected from an investigation site in a freshwater environment. The second procedure calculates an estimated value M of the amount of nucleic acids derived from fish species that may be false positives in the sample based on "M = M0e -kt ". M is the estimated value of the amount of nucleic acids derived from fish species that may be false positives at the investigation site. M0 is the amount of nucleic acids derived from fish species that may be false positives at the contamination point in the freshwater environment. k is the degradation rate constant. t is the time it takes for nucleic acids derived from fish species that may be false positives to reach the investigation site from the contamination point. The third procedure reduces false positives in the quantification result based on the estimated value M. Further, Patent Document 1 discloses mapping of estimation results. For the mapping of estimation results, the geographical information analysis support system MANDARA10 (ktgis.net / mandara / ) is used to visualize the contamination status by foreign nucleic acids across the country. Foreign nucleic acids include foreign eDNA and foreign eRNA. When foreign eDNA or eRNA contaminates a freshwater environment, it causes false positives in the ecological survey of the freshwater environment.

Therefore, the inventor investigated a technology that can inform those engaged in the protection and utilization of fishery resources in the river about the habitat status of aquatic organisms living there, while also allowing them to understand the sampling location of the water sample.

[0005] The present invention aims to provide a technology that allows those engaged in the protection and utilization of fishery resources in rivers to understand the location where the water sample used for environmental DNA analysis was collected, while also informing them of the habitat status of aquatic organisms living there. [Means for solving the problem]

[0006] One aspect of the present invention is that a processor of an information processing device including a storage device and a display device stores map data representing a map image of a specific area including a river, and stores first location information indicating a first point in the river, and first amount of environmental DNA of a first aquatic organism contained in water collected at the first point during the first sampling period, The first sampling information indicating the first sampling period, Associate and remember The system stores, in association with, a second location information indicating a second location in the river different from the first location, a second amount of environmental DNA of the first aquatic organism contained in the water collected at the second location during the first collection period, and the first collection information; the system stores, in association with, the first location information, a third amount of environmental DNA of the first aquatic organism contained in the water collected at the first location during the second collection period, which is later than the first collection period, and second collection information indicating the second collection period; and the system stores, in association with, the second location information, a fourth amount of environmental DNA of the first aquatic organism contained in the water collected at the second location during the second collection period, and the second collection information. The process of displaying the map image from the map data stored in the storage device. The process includes: a process to display a sampling area that includes the first sampling period and the second sampling period as options; a process to acquire the first sampling information when the sampling area is displayed and the selection of the first sampling period is accepted by the operating device of the information processing device; and a process to acquire the second sampling information when the sampling area is displayed and the selection of the second sampling period is accepted by the operating device. The process of executing and displaying the aforementioned map image is: When the first sampled information is obtained, the third quantity information corresponding to the third quantity is not placed on the map image. The first quantity information corresponding to the first quantity mentioned above The map image identified from the first location information At the aforementioned first point The map image is not placed with the fourth quantity information corresponding to the fourth quantity, but rather with the second quantity information corresponding to the second quantity placed at the second point on the map image identified from the second location information.

The aforementioned map image of Display on the aforementioned display device, When the second collection information and the first aquatic organism information are acquired, the map image is displayed on the display device in which the first quantity information is not placed on the map image, the third quantity information is placed on the first point on the map image identified from the first location information, and the second quantity information is not placed on the map image, but the fourth quantity information is placed on the second point on the map image identified from the second location information, and the first collection information and If the aforementioned second aquatic organism information is obtained, Without placing the seventh quantity information corresponding to the seventh quantity on the map image The fifth quantity information corresponding to the five quantities mentioned above The map image identified from the first location information At the aforementioned first point The information corresponding to the eighth quantity is not placed on the map image, and the information corresponding to the sixth quantity is placed at the second point on the map image identified from the second location information. The aforementioned map image of Display on the aforementioned display device When the second collection information and the second aquatic organism information are acquired, the map image is displayed on the display device in which the fifth quantity information is not placed on the map image, the seventh quantity information is placed at the first point on the map image identified from the first location information, and the sixth quantity information is not placed on the map image, but the eighth quantity information is placed at the second point on the map image identified from the second location information. You may do so.

[0014] Embodiments for carrying out the present invention will be described with reference to the drawings. The present invention is not limited to the configurations described below, and various configurations can be adopted within the same technical concept. For example, some of the configurations shown below may be omitted or replaced with other configurations. The present invention may include other configurations.

[0015] <Information Processing Device 10> The information processing device 10 will be described with reference to Figures 1 to 7. The information processing device 10 is a computer. The information processing device 10 reads programs and performs arithmetic processing. Examples of the information processing device 10 include tablet terminals, smartphones, and personal computers. Personal computers may be either desktop or laptop type. Laptop type personal computers are also called notebook computers. In this embodiment, the information processing device 10 is a tablet terminal (see Figures 1 to 5).

[0016] The information processing device 10 displays a map image of a specific area including a river (see Figures 1-5). The map image includes the habitat status of aquatic organisms at each or one of several points along the river included in this specific area. Examples of habitat status include habitat location and habitat concentration. Habitat concentration corresponds to the amount of environmental DNA. Further explanation of the map image will be given later. Examples of aquatic organisms inhabiting rivers include aquatic animals, aquatic plants, algae, aquatic fungi, and aquatic bacteria. Aquatic animals include fish, amphibians, reptiles, birds, mammals, crustaceans, mollusks, aquatic insects, and annelids. Aquatic animals may be either vertebrates or invertebrates. That is, in this embodiment, aquatic organisms inhabiting rivers are broadly interpreted and include various organisms whose DNA can be detected in the river water. In this embodiment, fish are used as examples of aquatic organisms inhabiting rivers. Examples of fish that inhabit rivers include the pale chub, the river goby, the carp, the crucian carp, the Japanese dace, the sweetfish, the cherry salmon, the char, and the Japanese loach. In this embodiment, three types of fish inhabiting rivers are given as examples: the first aquatic organism, the second aquatic organism, and the third aquatic organism. The first aquatic organism is the cherry salmon, the second aquatic organism is the Japanese dace, and the third aquatic organism is the Japanese loach (see Figures 1-5).

[0017] The first aquatic organism, the cherry salmon (yamame), releases its own unique environmental DNA into the environment (water). If this unique environmental DNA is detected in a water sample, cherry salmon inhabit the area where the water was collected and its surroundings. The second aquatic organism, the char (iwana), releases its own unique environmental DNA into the environment (water). If this unique environmental DNA is detected in a water sample, char inhabit the area where the water was collected and its surroundings. The third aquatic organism, the loach (ajimedojo), releases its own unique environmental DNA into the environment (water). If this unique environmental DNA is detected in a water sample, ajimedojo inhabit the area where the water was collected and its surroundings.

[0018] In this embodiment, ten locations are given as examples of water sampling locations for environmental DNA analysis. These ten locations are referred to as "Location A," "Location B," "Location C," "Location D," "Location E," "Location F," "Location G," "Location H," "Location I," and "Location J" (see Figures 1-5).

Location Information A through J are identified by GPS (Global Positioning System) and include latitude and longitude information. When location information A through J are not distinguished or are referred to collectively, they are simply called "location information."

[0019] In this embodiment, the sampling periods for the water samples used in the analysis of environmental DNA are exemplified as the first sampling period, the second sampling period, and the third sampling period. The first sampling period is set to March 1, 2024, the second sampling period to May 1, 2024, and the third sampling period to July 1, 2024 (see Figures 1-5). Information indicating the first sampling period is referred to as "first sampling information," information indicating the second sampling period is referred to as "second sampling information," and information indicating the third sampling period is referred to as "third sampling information." In this embodiment, the first sampling information is set to March 1, 2024, the second sampling information is set to May 1, 2024, and the third sampling information is set to July 1, 2024. When the first, second, and third sampling periods are not distinguished or are referred to collectively, they are simply referred to as "sampling period." When the first, second, and third sampling information are not distinguished or are referred to collectively, they are simply referred to as "sampling information."

[0020] For the analysis of environmental DNA, known analytical methods can be employed. Specifically, environmental DNA corresponding to cherry salmon, char, and loach can be detected by known analytical methods. Examples of known analytical methods include the MiFish method and species-specific detection. In this embodiment, a description of the environmental DNA analysis method is omitted.

[0021] The information processing device 10 includes a processor 11, a storage device 12, and a display device 15, and further includes an operating device 16 (see Figure 6). The storage device 12 stores various programs and data. Examples of programs include the OS (Operating System) and various applications. The applications include programs for display processing (see Figure 10). Examples of data include map data, the first aquatic organism table, the second aquatic organism table, and the third aquatic organism table (see Figures 6-9). The map data, the first aquatic organism table, the second aquatic organism table, and the third aquatic organism table are registered in the display processing program (see Figure 6).

[0022] The storage device 12 includes main memory 13 and storage 14. In the information processing device 10, the processor 11, the main memory 13 and storage 14 as storage devices 12, the display device 15 and the operating device 16 are connected to the bus 18.

[0023] The processor 11 performs arithmetic processing and controls the information processing device 10. An example of the processor 11 is a CPU. In the storage device 12, the main memory 13 is a volatile storage device, and the storage device 14 is a non-volatile storage device. An example of the main memory 13 is RAM. An example of the storage device 14 is flash memory. However, the storage device 14 does not have to be flash memory. The storage device 14 may be ROM or a hard disk. The storage device 14 may be a combination of two or more storage media. In this embodiment, when the main memory 13 and the storage device 14 are not distinguished or are referred to collectively, they are called the storage device 12.

[0024] Main memory 13 is used when the processor 11 executes various programs. Main memory 13 stores predetermined data in predetermined areas during processing. For example, main memory 13 stores the first aquatic organism table, the second aquatic organism table, and the third aquatic organism table. An example of main memory 13 is RAM. The above-mentioned programs that the storage device 12 stores are installed in storage 14. With the installation of the display processing program, storage 14 stores map data, the first aquatic organism table, the second aquatic organism table, and the third aquatic organism table.

[0025] The map data represents a map image of a specific area (see Figures 1-5). The specific area includes the following river. This river includes points A-J as the sampling locations for the water sample. An example of map data is OpenStreetMap®. In this embodiment, river data is imported into this map data. An example of river data is the data downloadable from the National Land Numerical Information Download Site (https: / / nlftp.mlit.go.jp / ksj / gml / datalist / KsjTmplt-W05.html). The river data from OpenStreetMap® and the National Land Numerical Information Download Site are publicly known, and the import of river data into OpenStreetMap® can also be done using publicly known methods. That is, the map data can be obtained using publicly known techniques. Further explanation regarding the map data is omitted in this embodiment.

[0026] The first aquatic organism table registers the results of environmental DNA analysis for the first aquatic organism, the cherry salmon (see Figure 7). In the first aquatic organism table, the amount of environmental DNA of the cherry salmon is associated with collection information and location information as an analysis result. The second aquatic organism table registers the results of environmental DNA analysis for the second aquatic organism, the char (see Figure 8). In the second aquatic organism table, the amount of environmental DNA of the char is associated with collection information and location information as an analysis result. The third aquatic organism table registers the results of environmental DNA analysis for the third aquatic organism, the loach (see Figure 9). In the third aquatic organism table, the amount of environmental DNA of the loach is associated with collection information and location information as an analysis result.

[0027] The display processing program is pre-installed in storage 14. The display processing program uses a known tablet device as the information processing device 10. The display processing program may also include the functionality of a web browser. The web browser retrieves predetermined data from a predetermined site on the internet and displays an image corresponding to this data. However, the functionality of the web browser may be implemented by a web browser program pre-stored in storage 14. Many known information processing devices store a web browser program in storage 14 as standard. In this case, the display processing process starts this web browser program.

[0028] The display device 15 displays various types of information. While display processing is in progress, the display device 15 displays the operation screen 20 (see Figures 1-5). The information processing device 10 displays the map image when the display device 15 displays the operation screen 20. Examples of the display device 15 include liquid crystal displays and organic EL displays. However, the display device 15 may be of a different format than liquid crystal displays and organic EL displays. The format of the display device 15 is determined appropriately considering various conditions.

[0029] The operating device 16 receives instructions and information corresponding to the operation. Examples of information include start instructions, end instructions, first aquatic organism information, second aquatic organism information, third aquatic organism information, first collection information, second collection information, and third collection information. A start instruction commands the start of display processing. The first aquatic organism information, second aquatic organism information, third aquatic organism information, first collection information, second collection information, and third collection information will be described later. The processor 11 acquires the instructions received by the operating device 16 from the operating device 16. If the information processing device 10 is a tablet terminal, the operating device 16 includes a touchpad. In this case, the operating device 16 is provided as an integral part of the display device 15. The display device 15 and the operating device 16 form a touch panel 17. When the operator inputs instructions, they perform tap, pinch, flick, or swipe operations on the operating device 16. However, the operating device 16 may be of a different form from the touch panel 17 that is integrated with the display device 15.

[0030] In the information processing device 10, the processor 11 executes the OS and display processing programs. Accordingly, the information processing device 10 displays the operation screen 20 on the display device 15. The operation screen 20 includes an exit button 21, a map area 22, and a selection area 23 (see Figures 1-5). The exit button 21 is associated with the instruction to terminate the display processing. When the operator wants to terminate the display processing, they tap the exit button 21. Assume that the exit button 21 has been tapped and this tap has been received by the operation device 16. In this case, the processor 11 receives the termination instruction and terminates the display processing.

[0031] Map area 22 displays a map image (see Figures 1-5). The map image includes a map of a specific area represented by map data. In map area 22, multiple quantitative information items, identified for each point A-J, are associated with each of points A-J and displayed together with the map image. The quantitative information corresponds to the amount of environmental DNA. The quantitative information may be the amount of environmental DNA, an amount calculated from the amount of environmental DNA by a predetermined algorithm (calculated value), or an amount estimated from the amount of environmental DNA by a predetermined law or empirical rule (estimated value). In this embodiment, the quantitative information is a combination of the following numerical value and a circular figure having the following area (see Figures 1-5). This numerical value indicates the amount of environmental DNA. This area has a constant relationship with the amount of environmental DNA. An example of a constant relationship is direct proportionality. Furthermore, if the amount of environmental DNA is 0, this area is set to a predetermined constant value.

[0032] In this embodiment, the quantity information displayed at point A on the map image is referred to as "Quantity Information A," the quantity information displayed at point B on the map image is referred to as "Quantity Information B," the quantity information displayed at point C on the map image is referred to as "Quantity Information C," the quantity information displayed at point D on the map image is referred to as "Quantity Information D," the quantity information displayed at point E on the map image is referred to as "Quantity Information E," the quantity information displayed at point F on the map image is referred to as "Quantity Information F," the quantity information displayed at point G on the map image is referred to as "Quantity Information G," the quantity information displayed at point H on the map image is referred to as "Quantity Information H," the quantity information displayed at point I on the map image is referred to as "Quantity Information I," and the quantity information displayed at point J on the map image is referred to as "Quantity Information J" (see Figures 1-5). When Quantity Information A-J are not distinguished or are referred to collectively, they are simply called "Quantity Information."

[0033] Let's assume the target is the cherry salmon, the primary aquatic organism. In this case, the quantitative information corresponds to the amount of environmental DNA of the cherry salmon, the primary aquatic organism. On the operation screen 20, the quantitative information for the cherry salmon, the primary aquatic organism, is displayed at a location on the map image identified from the location information associated with the amount of environmental DNA corresponding to that quantitative information in the primary aquatic organism table. Let's take the amount of cherry salmon environmental DNA identified from water collected at location A as an example. In this case, quantity information A is displayed at point A on the map image identified from location information A (see, for example, the amount of environmental DNA "1567" associated with "Location Information A" and "First Sampling Information (2024 / 3 / 1)" in Figure 7 and quantity information A "1567" shown at "Point A" in Figure 1; the amount of environmental DNA "906" associated with "Location Information B" and "Second Sampling Information (2024 / 5 / 1)" in Figure 7 and quantity information B "906" shown at "Point B" in Figure 2; and the amount of environmental DNA "981" associated with "Location Information C" and "Third Sampling Information (2024 / 7 / 1)" in Figure 7 and quantity information C "981" shown at "Point C" in Figure 3).

[0034] Let's assume the target is the char, a secondary aquatic organism. In this case, the quantitative information corresponds to the amount of environmental DNA of the char, a secondary aquatic organism. On the operation screen 20, the quantitative information for the char, a secondary aquatic organism, is displayed at a location on the map image identified from the location information associated with the amount of environmental DNA corresponding to that quantitative information in the secondary aquatic organism table. Let's take the amount of environmental DNA of the char identified from water collected at location C as an example. In this case, the quantitative information C is displayed at location C on the map image identified from the location information C (see, for example, the amount of environmental DNA "82" associated with "Location Information C" and "First Sampling Information (2024 / 3 / 1)" in Figure 8 and the quantitative information C "82" shown at "Location C" in Figure 4).

[0035] Let's assume the target organism is the loach (Misgurnus fuscoguttatus), a third-class aquatic organism. In this case, the quantitative information corresponds to the amount of environmental DNA (EDNA) of the loach. On the operation screen 20, the quantitative information for the loach is displayed at a location on the map image identified from the location information associated with the amount of environmental DNA corresponding to that quantitative information in the third-class aquatic organism table. Let's take the amount of EDNA identified from water collected at location B as an example. In this case, this quantitative information is displayed at location B on the map image identified from location information B (for example, see the amount of environmental DNA "514" associated with "Location Information B" and "First Collection Information (2024 / 3 / 1)" in Figure 9 and the quantitative information B "514" shown at "Location B" in Figure 5).

[0036] Selection area 23 includes aquatic organism species area 30 and collection area 40. Aquatic organism species area 30 includes radio buttons 31 to 33 as options. Radio button 31 corresponds to the first aquatic organism, "Yamame," and is associated with the first aquatic organism information. Radio button 32 corresponds to the second aquatic organism, "Iwana," and is associated with the second aquatic organism information. Radio button 33 corresponds to the third aquatic organism, "Ajimedojo," and is associated with the third aquatic organism information. The operator selects one of radio buttons 31 to 33 in aquatic organism species area 30. The first aquatic organism information indicates the first aquatic organism, Yamame. The second aquatic organism information indicates the second aquatic organism, Iwana. The third aquatic organism information indicates the third aquatic organism, Ajimedojo. In the embodiments, when the first aquatic organism information, the second aquatic organism information, and the third aquatic organism information are not distinguished or are referred to collectively, they are simply called "aquatic organism information."

[0037] The sampling area 40 includes radio buttons 41 to 43 as options. Radio button 41 corresponds to the first sampling period, "March 1, 2024," and is associated with the first sampling information. Radio button 42 corresponds to the second sampling period, "May 1, 2024," and is associated with the second sampling information. Radio button 43 corresponds to the third sampling period, "July 1, 2024," and is associated with the third sampling information. The operator selects one of the radio buttons 41 to 43 in the sampling area 40.

[0038] If the operator selects "Yamame" by operating radio button 31 in the aquatic organism species area 30 (see Figures 1-3), the processor 11 acquires first aquatic organism information via the operating device 16. If the operator selects "Iwana" by operating radio button 32 in the aquatic organism species area 30 (see Figure 4), the processor 11 acquires second aquatic organism information via the operating device 16. If the operator selects "Ajimedojo" by operating radio button 33 in the aquatic organism species area 30 (see Figure 5), the processor 11 acquires third aquatic organism information via the operating device 16.

[0039] If the operator selects "March 1, 2024" by operating radio button 41 in the sampling area 40 (see Figures 1, 4, and 5), the processor 11 acquires the first sampling information via the operating device 16. If the operator selects "May 1, 2024" by operating radio button 42 in the sampling area 40 (see Figure 2), the processor 11 acquires the second sampling information via the operating device 16. If the operator selects "July 1, 2024" by operating radio button 43 in the sampling area 40 (see Figure 1, 4, and 5), the processor 11 acquires the first sampling information via the operating device 16. 3 (See reference), the processor 11 acquires third-party information via the operating device 16.

[0040] Suppose the operator selects "Yamame" by operating radio button 31 in the aquatic organism species area 30 and selects "March 1, 2024" by operating radio button 41 in the collection area 40 (see Figure 1). The processor 11 acquires the first aquatic organism information and the first collection information via the operating device 16. Suppose the operator selects "Yamame" by operating radio button 31 in the aquatic organism species area 30 and selects "May 1, 2024" by operating radio button 42 in the collection area 40 (see Figure 2). The processor 11 acquires the first aquatic organism information and the second collection information via the operating device 16. Suppose the operator selects "Yamame" by operating radio button 31 in the aquatic organism species area 30 and selects "July 1, 2024" by operating radio button 43 in the collection area 40 (see Figure 3). The processor 11 acquires the first aquatic organism information and the third collection information via the operating device 16.

[0041] Suppose the operator selects "Iwana" by operating radio button 32 in the aquatic organism species area 30 and selects "March 1, 2024" by operating radio button 41 in the collection area 40 (see Figure 4). The processor 11 acquires the second aquatic organism information and the first collection information via the operating device 16. Suppose the operator selects "Ajimedojo" by operating radio button 33 in the aquatic organism species area 30 and selects "March 1, 2024" by operating radio button 41 in the collection area 40 (see Figure 5). The processor 11 acquires the third aquatic organism information and the first collection information via the operating device 16.

[0042] The processor 11 performs the following processing during the display process. This processing corresponds to a selected aquatic species and collection period from among multiple aquatic species in the aquatic species region 30 and multiple collection periods in the collection region 40. This will be explained later.

[0043] While details are omitted, the aquatic organism species area 30 may include radio buttons 31-33 as well as radio buttons corresponding to the fourth and subsequent aquatic organisms, and the collection area 40 may include radio buttons 41-43 as well as radio buttons corresponding to the fourth and subsequent collection periods. For example, when the operator selects the fourth aquatic organism, they select it by operating the radio button corresponding to the fourth aquatic organism. The radio button corresponding to the fourth aquatic organism is associated with the fourth aquatic organism information. For example, when the operator selects the fourth collection period, they select it by operating the radio button corresponding to the fourth collection period. The radio button corresponding to the fourth collection period is associated with the fourth collection information.

[0044] The menu format for the aquatic organism species area 30 is determined appropriately considering various conditions. For example, the aquatic organism species area 30 may be in a pull-down format. This pull-down menu includes options for the first aquatic organism, the second aquatic organism, and the third aquatic organism. As mentioned above, the aquatic organism species area 30 may also include options for the fourth and subsequent aquatic organisms, regardless of the menu format. The menu format for the collection area 40 is determined appropriately considering various conditions. For example, the collection area 40 may be in a slider format. This slider menu includes options for the first collection period, the second collection period, and the third collection period. As mentioned above, the collection area 40 may also include options for the fourth and subsequent collection periods, regardless of the menu format.

[0045] <Display Processing> The display process will be explained with reference to Figure 10. The operator inputs a start command for the display process by operating the operating device 16. The information processing device 10 receives the start command from the operating device 16. The processor 11 obtains the start command via the operating device 16. In response to the acquisition of the start command, the processor 11 starts the display process program stored in the storage 14. In the information processing device 10, the processor 11 starts the display process.

[0046] Upon commencement of the display process, the processor 11 displays an initial screen (not shown) as the operation screen 20 on the display device 15. The appearance of the initial screen is determined appropriately considering various conditions. For example, the initial screen may include the following message. This message prompts the user to select aquatic organism information and collection period. The user performs a first selection operation on the aquatic organism species area 30 of the operation screen 20, and a second selection operation on the collection area 40 of the operation screen 20. The first selection operation selects which of the following aquatic organism species will have quantity information displayed: the first aquatic organism (yamame trout), the second aquatic organism (iwana trout), and the third aquatic organism (ajimedojo loach). The second selection operation selects which of the following collection periods will be used: the first collection period on March 1, 2024, the second collection period on May 1, 2024, and the third collection period on July 1, 2024. The first selection operation is performed on any of the radio buttons 31 to 33, and the second operation is performed on any of the radio buttons 41 to 43. The processor 11 acquires aquatic organism information, either the first aquatic organism information, the second aquatic organism information, or the third aquatic organism information, and collection information, either the first collection information, the second collection information, or the third collection information, via the operating device 16 (S11).

[0047] If the operator wants to know the habitat status of the first aquatic organism, the cherry salmon, in a specific area during the first sampling period on March 1, 2024, they select radio buttons 31 and 41 (see Figure 1). In this case, the processor 11 acquires the first aquatic organism information and the first sampling information via the operating device 16 (S11). If the operator wants to know the habitat status of the first aquatic organism, the cherry salmon, in a specific area during the second sampling period on May 1, 2024, they select radio buttons 31 and 42 (see Figure 2). In this case, the processor 11 acquires the first aquatic organism information and the second sampling information via the operating device 16 (S11). If the operator wants to know the habitat status of the first aquatic organism, the cherry salmon, in a specific area during the third sampling period on July 1, 2024, they select radio buttons 31 and 43 (see Figure 3). In this case, the processor 11 acquires the first aquatic organism information and the third sampling information via the operating device 16 (S11).

[0048] If the operator wants to know the habitat status of the second aquatic organism, the char, in a specific area during the first sampling period on March 1, 2024, they select radio buttons 32 and 41 (see Figure 4). In this case, the processor 11 acquires the second aquatic organism information and the first sampling information via the operating device 16 (S11). If the operator wants to know the habitat status of the second aquatic organism, the char, in a specific area during the second sampling period on May 1, 2024, they select radio buttons 32 and 42 (not shown). In this case, the processor 11 acquires the second aquatic organism information and the second sampling information via the operating device 16 (S11). If the operator wants to know the habitat status of the second aquatic organism, the char, in a specific area during the third sampling period on July 1, 2024, they select radio buttons 32 and 43 (not shown). In this case, the processor 11 acquires the second aquatic organism information and the third sampling information via the operating device 16 (S11).

[0049] If the operator wants to know the habitat status of the third aquatic organism, *Leptotrombidium goeringii*, in a specific area during the first sampling period on March 1, 2024, they select radio buttons 33 and 41 (see Figure 5). In this case, the processor 11 acquires the third aquatic organism information and the first sampling information via the operating device 16 (S11). If the operator wants to know the habitat status of the third aquatic organism, *Leptotrombidium goeringii*, in a specific area during the second sampling period on May 1, 2024, they select radio buttons 33 and 42 (not shown). In this case, the processor 11 acquires the third aquatic organism information and the second sampling information via the operating device 16 (S11). If the operator wants to know the habitat status of the third aquatic organism, *Leptotrombidium goeringii*, in a specific area during the third sampling period on July 1, 2024, they select radio buttons 33 and 43 (not shown). In this case, the processor 11 acquires the third aquatic organism information and the third sampling information via the operating device 16 (S11).

[0050] Processor 11 stores the aquatic organism information and collection information acquired in S11 in main memory 13. Next, processor 11 displays the map image on display device 15 (S13). Display device 15 displays the map image in the map area 22 of the operation screen 20. Assume that the aquatic organism information and collection information stored in main memory 13 are the first aquatic organism information and the first collection information. In this case, processor 11 accesses the first aquatic organism table according to the first aquatic organism information and reads the amount of environmental DNA for each location information A to J associated with the first collection information from the first aquatic organism table. Assume that the aquatic organism information and collection information stored in main memory 13 are the second aquatic organism information and the first collection information. In this case, processor 11 accesses the second aquatic organism table according to the second aquatic organism information and reads the amount of environmental DNA for each location information A to J associated with the first collection information from the second aquatic organism table. Assume that the aquatic organism information and collection information stored in main memory 13 are the third aquatic organism information and the first collection information. In this case, the processor 11 accesses the third aquatic organism table according to the third aquatic organism information and reads the amount of environmental DNA for each location information A to J associated with the first collection information from the third aquatic organism table. If the combination of aquatic organism information and collection information stored in the main memory 13 is different from those described above, the processor 11 performs processing as appropriate, similar to the case of the aforementioned combination. Explanations of other combinations are omitted. The processor 11 stores the amount of environmental DNA for each location information A to J in the main memory 13.

[0051] Next, the processor 11 generates quantity information for each of the location information A to J. Specifically, the processor 11 generates quantity information A from the amount of environmental DNA associated with location information A, quantity information B from the amount of environmental DNA associated with location information B, quantity information C from the amount of environmental DNA associated with location information C, quantity information D from the amount of environmental DNA associated with location information D, quantity information E from the amount of environmental DNA associated with location information E, quantity information F from the amount of environmental DNA associated with location information F, quantity information G from the amount of environmental DNA associated with location information G, quantity information H from the amount of environmental DNA associated with location information H, quantity information I from the amount of environmental DNA associated with location information I, and quantity information J from the amount of environmental DNA associated with location information J.

[0052] The processor 11 accesses the map data and stores it in the main memory 13. Then, the processor 11 incorporates quantitative information A to J into the map data in the following state and generates map data incorporating quantitative information A to J. In this state, quantitative information A is placed at point A on the map image identified by location information A, quantitative information B is placed at point B on the map image identified by location information B, quantitative information C is placed at point C on the map image identified by location information C, quantitative information D is placed at point D on the map image identified by location information D, quantitative information E is placed at point E on the map image identified by location information E, quantitative information F is placed at point F on the map image identified by location information F, quantitative information G is placed at point G on the map image identified by location information G, quantitative information H is placed at point H on the map image identified by location information H, quantitative information I is placed at point I on the map image identified by location information I, and quantitative information J is placed at point J on the map image identified by location information J. The processor 11 stores the map data, which incorporates the quantitative information A to J, in the main memory 13.

[0053] Next, the processor 11 outputs a display instruction to the display device 15 for the map data stored in the main memory 13. Accordingly, the display device 15 displays the map image represented by this map data in the map area 22 of the operation screen 20. The map image includes quantity information A at point A on the map image, quantity information B at point B on the map image, quantity information C at point C on the map image, quantity information D at point D on the map image, quantity information E at point E on the map image, quantity information F at point F on the map image, quantity information G at point G on the map image, quantity information H at point H on the map image, quantity information I at point I on the map image, and quantity information J at point J on the map image (see Figures 1-5).

[0054] After executing S13, the processor 11 determines whether new aquatic organism information has been acquired (S15). The operator can select an unselected radio button from radio buttons 31 to 33 if any of the radio buttons 31 to 33 is selected. Let's assume radio button 31 is selected (see Figures 1 to 3). In this case, the operator selects radio button 32 to check the habitat status of the second aquatic organism, the char (see Figure 4), or selects radio button 33 to check the habitat status of the third aquatic organism, the loach (see Figure 5).

[0055] Assume that radio button 32 is selected (see Figure 4). In this case, the operator selects radio button 31 to check the habitat status of the first aquatic organism, the cherry salmon (see Figures 1-3), or selects radio button 33 to check the habitat status of the third aquatic organism, the loach (see Figure 5).

[0056] Assume that radio button 33 is selected (see Figure 5). In this case, the operator selects radio button 31 to check the habitat status of the first aquatic organism, the cherry salmon (see Figures 1-3), or selects radio button 32 to check the habitat status of the second aquatic organism, the char (see Figure 4).

[0057] Assume that no operation is received by the operating device 16 for any of the unselected radio buttons 31-33. In this case, the processor 11 does not determine that new aquatic organism information has been acquired (S15: No). The processor 11 proceeds to S19. Assume that an operation is received by the operating device 16 for any of the unselected radio buttons 31-33. In this case, the processor 11 acquires new aquatic organism information via the operating device 16. The processor 11 determines that new aquatic organism information has been acquired (S15: Yes) and updates the aquatic organism information stored in the main memory 13 with the newly acquired aquatic organism information (S17). After that, the processor 11 returns to S13. In S13, the processor 11 displays the map image on the display device 15 according to the aquatic organism information and collection information stored in the main memory 13, as described above.

[0058] In S19, processor 11 determines whether new sampling information has been acquired. The operator can select an unselected radio button from radio buttons 41 to 43 if any of the radio buttons 41 to 43 is selected. S19 will be explained using the first aquatic organism, the cherry salmon, as an example. Assume that radio button 41 is selected (see Figure 1). In this case, the operator selects radio button 42 to check the habitat status of the first aquatic organism, the cherry salmon, on May 1, 2024, during the second sampling period (see Figure 2), or selects radio button 43 to check the habitat status of the first aquatic organism, the cherry salmon, on July 1, 2024, during the third sampling period (see Figure 3).

[0059] Assume that radio button 42 is selected (see Figure 2). In this case, the operator selects radio button 41 to check the habitat status of the first aquatic organism, the cherry salmon, on March 1, 2024, during the first sampling period (see Figure 1), or selects radio button 43 to check the habitat status of the first aquatic organism, the cherry salmon, on July 1, 2024, during the third sampling period (see Figure 3).

[0060] Assume that radio button 43 is selected (see Figure 3). In this case, the operator selects radio button 41 to check the habitat status of the first aquatic organism, the cherry salmon, on March 1, 2024, during the first sampling period (see Figure 1), or selects radio button 42 to check the habitat status of the first aquatic organism, the cherry salmon, on May 1, 2024, during the second sampling period (see Figure 2).

[0061] Assume that no operation is received by the operating device 16 for any of the unselected radio buttons 41-43. In this case, the processor 11 does not determine that new collection information has been acquired (S19: No). The processor 11 proceeds to S23. Assume that an operation is received by the operating device 16 for any of the unselected radio buttons 41-43. In this case, the processor 11 acquires new collection information via the operating device 16. The processor 11 determines that new collection information has been acquired (S19: Yes) and updates the collection information stored in the main memory 13 with the newly acquired collection information (S21). After that, the processor 11 returns to S13. In S13, the processor 11 displays the map image on the display device 15 according to the aquatic organism information and collection information stored in the main memory 13, as described above.

[0062] In S23, the processor 11 determines whether it has received a termination instruction. The operator operates the termination button 21 on the operation screen 20. If the operation of the termination button 21 is not received by the operation device 16, the processor 11 does not receive a termination instruction. In this case, the processor 11 does not determine that it has received a termination instruction (S23: No). The processor 11 returns to processing S15. After that, the processor 11 executes the processing from S15 onwards in the same manner as above. If the operation of the termination button 21 is received by the operation device 16, the processor 11 receives a termination instruction via the operation device 16. In this case, the processor 11 determines that it has received a termination instruction (S23: Yes) and terminates the display process.

[0063] <Effects of the Embodiment> According to this embodiment, the following effects can be obtained.

[0064] (1) The information processing device 10 includes a processor 11, a storage device 12, and a display device 15 (see Figure 6). The storage device 12 stores a program for display processing (see Figure 10), map data, a first aquatic organism table, a second aquatic organism table, and a third aquatic organism table. The first aquatic organism table registers the results of environmental DNA analysis targeting the first aquatic organism, the cherry salmon (see Figure 7). In the first aquatic organism table, the amount of environmental DNA of the cherry salmon is associated with collection information and location information as an analysis result. The second aquatic organism table registers the results of environmental DNA analysis targeting the second aquatic organism, the char (see Figure 8). In the second aquatic organism table, the amount of environmental DNA of the char is associated with collection information and location information as an analysis result. The third aquatic organism table registers the results of environmental DNA analysis targeting the third aquatic organism, the loach (see Figure 9). In the third aquatic organism table, the amount of environmental DNA of the loach is associated with collection information and location information as an analysis result. Processor 11 executes the display processing program.

[0065] The display processing program causes the processor 11 to generate a map image from map data and to execute the process of displaying the map image on the display device 15 (see S13 in Figure 10). The process executed in S13 in Figure 10 displays quantity information A to J together with the map image in the following manner (see Figures 1 to 5). In this manner, quantity information A is associated with point A, quantity information B is associated with point B, quantity information C is associated with point C, quantity information D is associated with point D, quantity information E is associated with point E, quantity information F is associated with point F, quantity information G is associated with point G, quantity information H is associated with point H, quantity information I is associated with point I, and quantity information J is associated with point J.

[0066] According to the display processing program and information processing device 10, for example, the habitat status of the first aquatic organism, the cherry salmon, can be identified by environmental DNA identified from water samples taken from the river, and the habitat status of the first aquatic organism, the cherry salmon, can be displayed in association with a map image (see Figure 1). A viewer looking at the map image in Figure 1 can check the habitat status of the first aquatic organism, the cherry salmon, at river locations A to J on March 1, 2024, the first sampling period, while confirming the map image. In other words, the display processing program and information processing device 10 can display the habitat status of the first aquatic organism, the cherry salmon, on a map image (see Figure 1), and a viewer can check the habitat status of the first aquatic organism, the cherry salmon, at river locations A to J on March 1, 2024, the first sampling period. The display processing program and information processing device 10 can inform those engaged in the protection and utilization of fishery resources in rivers about the habitat status of aquatic organisms living there, while also allowing them to understand the sampling locations of the water samples used for environmental DNA analysis. The display processing program and information processing device 10 can be used to help protect and utilize fishery resources in rivers.

[0067] (2) The display processing program causes the processor 11 to execute a process to acquire the first sampling information when the operating device 16 receives the first sampling period, March 1, 2024; to execute a process to acquire the second sampling information when the operating device 16 receives the second sampling period, May 1, 2024; and to execute a process to acquire the third sampling information when the operating device 16 receives the third sampling period, July 1, 2024 (see S11, S19: Yes in Figure 10).

[0068] The target organism is the cherry salmon, the first aquatic organism. The process performed in S13 of Figure 10 is as follows: When the first sampling information is obtained, the first aquatic organism table displays the first sampling information and the quantity information A to J corresponding to the amount of environmental DNA for each location A to J associated with location information A to J, along with a map image in the following manner (see Figure 1); when the second sampling information is obtained, the first aquatic organism table displays the second sampling information and the quantity information A to J corresponding to the amount of environmental DNA for each location A to J associated with location information A to J, along with a map image in the following manner (see Figure 2); and when the third sampling information is obtained, the first aquatic organism table displays the third sampling information and the quantity information A to J corresponding to the amount of environmental DNA for each location A to J associated with location information A to J, along with a map image in the following manner (see Figure 3). In this embodiment, quantity information A is associated with location A, quantity information B with location B, quantity information C with location C, quantity information D with location D, quantity information E with location E, quantity information F with location F, quantity information G with location G, quantity information H with location H, quantity information I with location I, and quantity information J with location J.

[0069] According to this configuration, if March 1, 2024, the first sampling period, is selected as the habitat status of the primary aquatic organism, the cherry salmon, at points A to J in the river, then March 1, 2024, the first sampling period, can be displayed (see Figure 1); if May 1, 2024, the second sampling period, is selected, then May 1, 2024, the second sampling period, can be displayed (see Figure 2); and if July 1, 2024, the third sampling period, is selected, then July 1, 2024, the third sampling period, can be displayed (see Figure 3). For example, it is presumed that the habitat of the primary aquatic organism, the cherry salmon, moved from point B in the river to other points (for example, see points A, C, and D) during the two-month period from March 1, 2024, the first sampling period, to May 1, 2024, the second sampling period (see Figures 1, 2, and 7). By switching the displayed data from the first harvesting period on March 1, 2024, to the second harvesting period on May 1, 2024, viewers can be made aware of the changes in the habitat of the first aquatic organism, the cherry salmon.

[0070] (3) The display processing program causes the processor 11 to execute a process to acquire information on the first aquatic organism when the operating device 16 receives the first aquatic organism, a cherry salmon; to execute a process to acquire information on the second aquatic organism when the operating device 16 receives the second aquatic organism, a char; and to execute a process to acquire information on the third aquatic organism when the operating device 16 receives the third aquatic organism, a loach (see S11, S15: Yes in Figure 10).

[0071] The target date is March 1, 2024, the first sampling period. The process performed in S13 of Figure 10 is as follows: If the first aquatic organism information is obtained, the first aquatic organism table displays the quantity information A to J corresponding to the amount of environmental DNA for each location A to J associated with the first sampling information and location information A to J, along with a map image in the following manner (see Figure 1); if the second aquatic organism information is obtained, the second aquatic organism table displays the quantity information A to J corresponding to the amount of environmental DNA for each location A to J associated with the first sampling information and location information A to J, along with a map image in the following manner (see Figure 4); and if the third aquatic organism information is obtained, the third aquatic organism table displays the quantity information A to J corresponding to the amount of environmental DNA for each location A to J associated with the first sampling information and location information A to J, along with a map image in the following manner (see Figure 5). In this embodiment, quantity information A is associated with location A, quantity information B with location B, quantity information C with location C, quantity information D with location D, quantity information E with location E, quantity information F with location F, quantity information G with location G, quantity information H with location H, quantity information I with location I, and quantity information J with location J.

[0072] With this configuration, if the first aquatic organism, the cherry salmon, is selected, the habitat status of the first aquatic organism, the cherry salmon, can be displayed; if the second aquatic organism, the char, is selected, the habitat status of the second aquatic organism, the char, can be displayed; and if the third aquatic organism, the loach, is selected, the habitat status of the third aquatic organism, the loach, can be displayed.

[0073] (4) The process executed in S13 of Figure 10 further displays the quantity information A to J in the following manner (see Figures 1 to 5). In this manner, quantity information A is displayed at point A on the map image identified from location information A, quantity information B is displayed at point B on the map image identified from location information B, quantity information C is displayed at point C on the map image identified from location information C, quantity information D is displayed at point D on the map image identified from location information D, quantity information E is displayed at point E on the map image identified from location information E, quantity information F is displayed at point F on the map image identified from location information F, quantity information G is displayed at point G on the map image identified from location information G, quantity information H is displayed at point H on the map image identified from location information H, quantity information I is displayed at point I on the map image identified from location information I, and quantity information J is displayed at point J on the map image identified from location information J.

[0074] This configuration allows the habitat status of any of the following aquatic organisms—the first aquatic organism (Yamame trout), the second aquatic organism (Iwana trout), and the third aquatic organism (Ajimedojo loach)—to be displayed on a map image for any of the following collection periods: the first collection period on March 1, 2024; the second collection period on May 1, 2024; and the third collection period on July 1, 2024 (see Figures 1-5). Viewers can then check the habitat status of the first aquatic organism (Yamame trout) at river locations A-J on the map image for March 1, 2024 (see Figure 1), May 1, 2024 (see Figure 2), and July 1, 2024 (see Figure 3). Viewers can check the habitat status of the second aquatic organism, the char, at river locations A to J on March 1, 2024 (see Figure 4), on May 1, 2024 (not shown), and on July 1, 2024 (not shown), on the map image. Viewers can also check the habitat status of the third aquatic organism, the loach, at river locations A to J on March 1, 2024 (see Figure 5), on May 1, 2024 (not shown), and on July 1, 2024 (not shown), on the map image.

[0075] <Variation> The embodiment can also be as follows. Some of the modifications shown below can be combined and adopted as appropriate. Below, we will explain the differences from the above, and explain the similarities as appropriate.

[0076] (1) The sampling period was specified by "year, month, and day". The sampling period may also be specified by year and month. The month may be a period that includes multiple months. Examples of periods that include multiple months include "January to March, April to June, July to September, October to December" and "January to June, July to December". The number of months that define one period and the start and end months of one period shall be set appropriately considering various conditions.
