[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 wastewater 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 = M 0 e -kt ". M is an estimated value of the amount of nucleic acids derived from fish species that may be false positives at the investigation site. M 0 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 a 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 the estimation results. For the mapping of the 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.

[0007] According to this program, the habitat status of the first aquatic organism can be specified by environmental DNA specified from water collected in a river, and the habitat status of the first aquatic organism can be associated and displayed on a map image. That is, the living situation of the first aquatic organism can be displayed on the map image. As the living situation of the first aquatic organism at the first point and the second point of the river, when the first sampling period is selected, the first sampling period can be the display target, and when the second sampling period is selected, the second sampling period can be the display target.

When the second collection information and the first aquatic organism information are obtained, the display device is caused to display the map image in which the third amount information is arranged at the first location on the map image specified by the first position information without arranging the first amount information thereon and the fourth amount information is arranged at the second location on the map image specified by the second position information without arranging the second amount information thereon. When the first collection information and the second aquatic organism information are obtained, the seventh amount A combination of a numerical value indicating and a figure of an area having a certain relationship with the seventh quantity, and a mode in which a part of the numerical value indicating the seventh quantity is arranged on the figure of the area having the certain relationship with the seventh quantityPlace the seventh quantity information at the first point on the map image specified from the first position information without placing the fifth quantity information on the map image. A combination of a numerical value indicating and a figure of an area having a certain relationship with the fifth quantity, and a mode in which a part of the numerical value indicating the fifth quantity is arranged on the figure of the area having the certain relationship with the fifth quantity Place the fifth quantity information at the first point on the map image specified from the first position information and the eighth quantity A combination of a numerical value indicating and a figure of an area having a certain relationship with the eighth quantity, and a mode in which a part of the numerical value indicating the eighth quantity is arranged on the figure of the area having a certain relationship with the eighth quantity Place the eighth quantity information at the second point on the map image specified from the second position information without placing the sixth quantity information on the map image.

The storage 14 may be a combination of two or more storage media. In the embodiment, when the main memory 13 and the storage 14 are not distinguished or when they are collectively referred to, they are called the storage device 12.

[0024] The main memory 13 is used when the processor 11 executes various programs. The main memory 13 stores predetermined data in a predetermined area during the execution of processing. For example, the main memory 13 stores a first aquatic organism table, a second aquatic organism table, and a third aquatic organism table. An example of the main memory 13 is a RAM. The above-described program stored in the storage device 12 is installed in the storage 14. By installing the display processing program, the storage 14 stores map data, a first aquatic organism table, a second aquatic organism table, and a third aquatic organism table.

[0025] The map data represents a map image of a specific area (see FIGS. 1 to 5). The specific area includes the following river. This river includes points A to J as sampling positions of the sampled water. An example of the map data is OpenStreetMap (registered trademark). In the embodiment, river data is imported into this map data. An example of the river data is data that can be downloaded from the National Numerical Information Download Site (https: / / nlftp.mlit.go.jp / ksj / gml / datalist / KsjTmplt-W05.html). The river data of OpenStreetMap (registered trademark) and the National Numerical Information Download Site is known, and the import of the river data into OpenStreetMap (registered trademark) can also be performed by a known method. That is, the map data can be obtained by a known technique. In the embodiment, other explanations regarding the map data are omitted.

[0026] The analysis results of environmental DNA targeting the masu salmon, the first aquatic organism, are registered in the first aquatic organism table (see Fig. 7). In the first aquatic organism table, the amount of environmental DNA of the masu salmon as the analysis result is associated with the sampling information and the location information. The analysis results of environmental DNA targeting the char, the second aquatic organism, are registered in the second aquatic organism table (see Fig. 8). In the second aquatic organism table, the amount of environmental DNA of the char as the analysis result is associated with the sampling information and the location information. The analysis results of environmental DNA targeting the Japanese bullhead shark, the third aquatic organism, are registered in the third aquatic organism table (see Fig. 9). In the third aquatic organism table, the amount of environmental DNA of the Japanese bullhead shark as the analysis result is associated with the sampling information and the location information.

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

[0028] The display device 15 displays various types of information. During the execution of the display processing, the display device 15 displays the operation screen 20 (see Figs. 1 to 5). The information processing device 10 displays a map image when the display device 15 displays the operation screen 20. Examples of the display device 15 include a liquid crystal display and an organic EL display. However, the display device 15 may have a form different from that of the liquid crystal display and the organic EL display.

The display device 15 and the operation device 16 form a touch panel 17. When the operator inputs an instruction, the operator performs a tap, pinch, flick, or swipe operation on the operation device 16. However, the operation device 16 may have 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 an OS and a display process program. Accordingly, an operation screen 20 is displayed on the display device 15 in the information processing device 10. The operation screen 20 includes an end button 21, a map area 22, and a selection area 23 (see FIGS. 1 to 5). The end button 21 is associated with an end instruction for the display process. When the operator ends the display process, the operator taps the end button 21. Assume that the end button 21 is tapped and this tap is received by the operation device 16.

In the embodiment, when the first aquatic organism information, the second aquatic organism information, and the third aquatic organism information are not distinguished or when they are collectively referred to, they are simply called "aquatic organism information".

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

[0038] When the operator operates the radio button 31 in the aquatic species area 30 to select "yamame" (see FIGS. 1 to 3), the processor 11 acquires the first aquatic organism information via the operating device 16. When the operator operates the radio button 32 in the aquatic species area 30 to select "iwana" (see FIG. 4), the processor 11 acquires the second aquatic organism information via the operating device 16. When the operator operates the radio button 33 in the aquatic species area 30 to select "ajimedojo" (see FIG. 5), the processor 11 acquires the third aquatic organism information via the operating device 16.

[0039] When the operator operates the radio button 41 in the collection area 40 to select "March 1, 2024" (see FIGS. 1, 4, 5), the processor 11 acquires the first collection information via the operating device 16. When the operator operates the radio button 42 in the collection area 40 to select "May 1, 2024" (see FIG. 2), the processor 11 acquires the second collection information via the operating device 16. When the operator operates the radio button 43 in the collection area 40 to select "July 1, 2024" (see FIG. 3 reference), the processor 11 acquires the third collection information via the operating device 16.

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

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

[0042] The processor 11 executes the following process in the display process. This process corresponds to the selected aquatic species and collection period among the plurality of aquatic species in the aquatic species area 30 and the plurality of collection periods in the collection area 40. This will be described later.

[0043] Although the details are omitted, the aquatic species area 30 may include radio buttons for the fourth and subsequent aquatic species in addition to the radio buttons 31 to 33, and the collection area 40 may include radio buttons for the fourth and subsequent collection periods in addition to the radio buttons 41 to 43. For example, when the operator selects the fourth aquatic species, the operator operates the radio button corresponding to the fourth aquatic species to select the fourth aquatic species. The radio button corresponding to the fourth aquatic species is associated with the fourth aquatic species information. For example, when the operator selects the fourth collection period, the operator operates the radio button corresponding to the fourth collection period to select the fourth collection period. The radio button corresponding to the fourth collection period is associated with the fourth collection information.

[0044] The menu format of the aquatic species area 30 is appropriately determined in consideration of various conditions. For example, the aquatic species area 30 may be in a pull-down format. This pull-down menu includes the first aquatic species, the second aquatic species, and the third aquatic species as options. In the aquatic species area 30, as described above, regardless of the menu format, it may include options for the fourth and subsequent aquatic species corresponding to the fourth and subsequent aquatic species. The menu format of the sampling area 40 is appropriately determined in consideration of various conditions. For example, the sampling area 40 may be in a slider format. This slider menu includes the first sampling period, the second sampling period, and the third sampling period as options. In the sampling area 40, as described above, regardless of the menu format, it may include options for the fourth and subsequent sampling periods corresponding to the fourth and subsequent sampling periods.

[0045] <Display processing> The display processing will be described with reference to FIG. 10. The operator operates the operation device 16 to input an instruction to start the display processing. The information processing device 10 receives the start instruction by the operation device 16. The processor 11 acquires the start instruction via the operation device 16. The processor 11 starts the program for the display processing stored in the storage 14 in response to the acquisition of the start instruction. In the information processing device 10, the processor 11 starts the display processing.

[0046] Upon the start of the display process, the processor 11 causes the display device 15 to display an initial screen (not shown) as the operation screen 20. The form of the initial screen is appropriately determined in consideration of various conditions. For example, the initial screen may include the following message. This message prompts the selection of aquatic organism information and the collection period. The operator 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 rainbow trout of the first aquatic organism, the char of the second aquatic organism, and the Japanese sand lance of the third aquatic organism to display the quantity information for. The second selection operation selects which of the first collection period of March 1, 2024, the second collection period of May 1, 2024, and the third collection period of July 1, 2024 to set as the collection period. The first selection operation is performed on any one of the radio buttons 31 to 33, and the second operation is performed on any one of the radio buttons 41 to 43. The processor 11 acquires either the aquatic organism information of the first aquatic organism information, the second aquatic organism information, and the third aquatic organism information or the collection information of the first collection information, the second collection information, and the third collection information via the operation device 16 (S11).

[0047] When the operator wants to know the habitat status of rainbow trout of the first aquatic organism on March 1, 2024, which is the first collection period within a specific area, the operator selects the radio buttons 31 and 41 (see Fig. 1). In this case, the processor 11 acquires the first aquatic organism information and the first collection information via the operation device 16 (S11). When the operator wants to know the habitat status of rainbow trout of the first aquatic organism on May 1, 2024, which is the second collection period within a specific area, the operator selects the radio buttons 31 and 42 (see Fig. 2). In this case, the processor 11 acquires the first aquatic organism information and the second collection information via the operation device 16 (S11). When the operator wants to know the habitat status of rainbow trout of the first aquatic organism on July 1, 2024, which is the third collection period within a specific area, the operator selects the radio buttons 31 and 43 (see Fig. 3). In this case, the processor 11 acquires the first aquatic organism information and the third collection information via the operation device 16 (S11).

[0048] If the operator wants to know the living situation of char, the second aquatic organism, on March 1, 2024, during the first sampling period in a specific area, the operator selects the radio buttons 32, 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 living situation of char, the second aquatic organism, on May 1, 2024, during the second sampling period in a specific area, the operator selects the radio buttons 32, 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 living situation of char, the second aquatic organism, on July 1, 2024, during the third sampling period in a specific area, the operator selects the radio buttons 32, 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 living situation of Japanese sand lance, the third aquatic organism, on March 1, 2024, during the first sampling period in a specific area, the operator selects the radio buttons 33, 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 living situation of Japanese sand lance, the third aquatic organism, on May 1, 2024, during the second sampling period in a specific area, the operator selects the radio buttons 33, 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 living situation of Japanese sand lance, the third aquatic organism, on July 1, 2024, during the third sampling period in a specific area, the operator selects the radio buttons 33, 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] The processor 11 stores the aquatic organism information and collection information obtained in S11 in the main memory 13. Next, the processor 11 causes the display device 15 to display a map image (S13). The 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 the main memory 13 are the first aquatic organism information and the first collection information. In this case, the processor 11 accesses the first aquatic organism table according to the first aquatic organism information, and reads out the amount of environmental DNA for each of the position information A to J associated with the first collection information in the first aquatic organism table. Assume that the aquatic organism information and collection information stored in the main memory 13 are the second aquatic organism information and the first collection information. In this case, the processor 11 accesses the second aquatic organism table according to the second aquatic organism information, and reads out the amount of environmental DNA for each of the position information A to J associated with the first collection information in the second aquatic organism table. Assume that the aquatic organism information and collection information stored in the 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 out the amount of environmental DNA for each of the position information A to J associated with the first collection information in the third aquatic organism table. When the combination of the aquatic organism information and collection information stored in the main memory 13 is different from the above, the processor 11 appropriately executes processing according to the case of the above-described combination. Explanation of other combinations is omitted. The processor 11 stores the amount of environmental DNA for each of the position information A to J in the main memory 13.

[0051] Subsequently, the processor 11 generates quantity information for each of the position information A to J. That is, the processor 11 generates corresponding quantity information A from the quantity of environmental DNA associated with the position information A, generates corresponding quantity information B from the quantity of environmental DNA associated with the position information B, generates corresponding quantity information C from the quantity of environmental DNA associated with the position information C, generates corresponding quantity information D from the quantity of environmental DNA associated with the position information D, generates corresponding quantity information E from the quantity of environmental DNA associated with the position information E, generates corresponding quantity information F from the quantity of environmental DNA associated with the position information F, generates corresponding quantity information G from the quantity of environmental DNA associated with the position information G, generates corresponding quantity information H from the quantity of environmental DNA associated with the position information H, generates corresponding quantity information I from the quantity of environmental DNA associated with the position information I, and generates corresponding quantity information J from the quantity of environmental DNA associated with the position information J.

[0052] The processor 11 accesses the map data and stores the map data in the main memory 13. Then, the processor 11 incorporates the quantity information A to J into the map data in the following state to generate map data incorporating the quantity information A to J. In this state, the quantity information A is arranged at the point A on the map image specified by the position information A, the quantity information B is arranged at the point B on the map image specified by the position information B, the quantity information C is arranged at the point C on the map image specified by the position information C, the quantity information D is arranged at the point D on the map image specified by the position information D, the quantity information E is arranged at the point E on the map image specified by the position information E, the quantity information F is arranged at the point F on the map image specified by the position information F, the quantity information G is arranged at the point G on the map image specified by the position information G, the quantity information H is arranged at the point H on the map image specified by the position information H, the quantity information I is arranged at the point I on the map image specified by the position information I, and the quantity information J is arranged at the point J on the map image specified by the position information J. The processor 11 stores the map data incorporating the quantity information A to J in the main memory 13.

[0053] Next, the processor 11 outputs an instruction to display the map data stored in the main memory 13 to the display device 15. Accordingly, the display device 15 displays a 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 FIGS. 1 to 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 among the radio buttons 31 to 33 while any one of the radio buttons 31 to 33 is selected. Assume that the radio button 31 is selected (see FIGS. 1 to 3). In this case, when the operator wants to check the habitat status of the second aquatic organism, the ayu, the operator selects the radio button 32 (see FIG. 4), or when the operator wants to check the habitat status of the third aquatic organism, the red sea bream, the operator selects the radio button 33 (see FIG. 5).

[0055] Assume that the radio button 32 is selected (see FIG. 4). In this case, when the operator wants to check the habitat status of the first aquatic organism, the yamame, the operator selects the radio button 31 (see FIGS. 1 to 3), or when the operator wants to check the habitat status of the third aquatic organism, the red sea bream, the operator selects the radio button 33 (see FIG. 5).

[0056] Assume that the radio button 33 is selected (see FIG. 5). In this case, when the operator wants to check the habitat status of the first aquatic organism, the yamame, the operator selects the radio button 31 (see FIGS. 1 to 3), or when the operator wants to check the habitat status of the second aquatic organism, the ayu, the operator selects the radio button 32 (see FIG. 4).

[0057] Assume that the operation device 16 has not received an operation on an unselected radio button among radio buttons 31 to 33. In this case, the processor 11 does not determine that new aquatic organism information has been acquired (S15: No). The processor 11 shifts the process to S19. Assume that the operation device 16 has received an operation on an unselected radio button among radio buttons 31 to 33. In this case, the processor 11 newly acquires aquatic organism information via the operation 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). Then, the processor 11 returns the process to S13. At S13, the processor 11, as described above, causes the display device 15 to display a map image according to the aquatic organism information and the collection information stored in the main memory 13.

[0058] At S19, the processor 11 determines whether new collection information has been acquired. The operator can select an unselected radio button among radio buttons 41 to 43 while one of radio buttons 41 to 43 is selected. S19 will be described using the first aquatic organism, ayu, as an example. Assume that radio button 41 is selected (see FIG. 1). In this case, when the operator wants to check the habitat status of ayu, the first aquatic organism, on May 1, 2024, the second collection period, the operator selects radio button 42 (see FIG. 2), or when the operator wants to check the habitat status of ayu, the first aquatic organism, on July 1, 2024, the third collection period, the operator selects radio button 43 (see FIG. 3).

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

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

[0061] Assume that the operation device 16 has not received an operation on the unselected radio button among radio buttons 41 to 43. In this case, the processor 11 does not determine that new collection information has been acquired (S19: No). The processor 11 shifts the process to S23. Assume that the operation device 16 has received an operation on the unselected radio button among radio buttons 41 to 43. In this case, the processor 11 newly acquires the collection information via the operation 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). Then, the processor 11 returns the process to S13. In S13, the processor 11 causes the display device 15 to display the map image according to the aquatic organism information and the collection information stored in the main memory 13 in the same manner as described above.

[0062] In S23, the processor 11 determines whether an end instruction has been acquired. The operator operates the end button 21 on the operation screen 20. When the operation device 16 has not received an operation on the end button 21, the processor 11 does not acquire the end instruction. In this case, the processor 11 does not determine that the end instruction has been acquired (S23: No). The processor 11 returns the process to S15. Then, the processor 11 executes the processes after S15 in the same manner as described above. When the operation device 16 has received an operation on the end button 21, the processor 11 acquires the end instruction via the operation device 16. In this case, the processor 11 determines that the end instruction has been acquired (S23: Yes), and ends the display process.

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

[0064] (1) The information processing apparatus 10 includes a processor 11, a storage device 12, and a display device 15 (see FIG. 6). The storage device 12 stores a program for display processing (see FIG. 10), map data, a first aquatic organism table, a second aquatic organism table, and a third aquatic organism table. In the first aquatic organism table, analysis results of environmental DNA targeting yamame, a first aquatic organism, are registered (see FIG. 7). In the first aquatic organism table, the amount of environmental DNA of yamame as an analysis result is associated with collection information and position information. In the second aquatic organism table, analysis results of environmental DNA targeting iwana, a second aquatic organism, are registered (see FIG. 8). In the second aquatic organism table, the amount of environmental DNA of iwana as an analysis result is associated with collection information and position information. In the third aquatic organism table, analysis results of environmental DNA targeting ajimedojo, a third aquatic organism, are registered (see FIG. 9). In the third aquatic organism table, the amount of environmental DNA of ajimedojo as an analysis result is associated with collection information and position information. The processor 11 executes a program for display processing.

[0065] The program for display processing causes the processor 11 to execute a process of generating a map image from the map data and displaying the map image on the display device 15 (see S13 in FIG. 10). The process executed in S13 of FIG. 10 causes quantity information A to J to be displayed together with the map image in the following manner (see FIGS. 1 to 5). This manner associates quantity information A with point A, quantity information B with point B, quantity information C with point C, quantity information D with point D, quantity information E with point E, quantity information F with point F, quantity information G with point G, quantity information H with point H, quantity information I with point I, and quantity information J with point J.

[0066] According to the display processing program and the information processing apparatus 10, for example, the habitat status of the first aquatic organism, the yamame, can be identified by environmental DNA identified from water collected in a river, and the habitat status of the first aquatic organism, the yamame, can be associated and displayed on a map image (see FIG. 1). A viewer who has seen the map image in FIG. 1 can confirm the habitat status of the first aquatic organism, the yamame, at points A to J in the river on March 1, 2024, during the first sampling period while checking the map image. That is, in the display processing program and the information processing apparatus 10, the habitat status of the first aquatic organism, the yamame, can be displayed on the map image (see FIG. 1), and the viewer can confirm the habitat status of the first aquatic organism, the yamame, at points A to J in the river on March 1, 2024, during the first sampling period. The display processing program and the information processing apparatus 10 can inform the person engaged in the protection and utilization of fishery resources in the river of the habitat status of the aquatic organisms living there while making them understand the sampling location of the water used as a sample for environmental DNA analysis. The display processing program and the information processing apparatus 10 can be used to assist in the protection and utilization of fishery resources in the river.

[0067] (2) When the operation device 16 receives March 1, 2024, as the first sampling period, the display processing program causes the processor 11 to execute a process of acquiring first sampling information. When the operation device 16 receives May 1, 2024, as the second sampling period, the display processing program causes the processor 11 to execute a process of acquiring second sampling information. When the operation device 16 receives July 1, 2024, as the third sampling period, the display processing program causes the processor 11 to execute a process of acquiring third sampling information (see S11, S19: Yes in FIG. 10).

[0068] It targets the yamame, a first aquatic organism. When the first collection information is obtained, the processing executed at S13 in FIG. 10 causes the amount information A to J corresponding to the amount of environmental DNA for each of the points A to J associated with the first collection information and the position information A to J in the first aquatic organism table to be displayed together with a map image in the following manner (see FIG. 1). When the second collection information is obtained, the amount information A to J corresponding to the amount of environmental DNA for each of the points A to J associated with the second collection information and the position information A to J in the first aquatic organism table is displayed together with a map image in the following manner (see FIG. 2). When the third collection information is obtained, the amount information A to J corresponding to the amount of environmental DNA for each of the points A to J associated with the third collection information and the position information A to J in the first aquatic organism table is displayed together with a map image in the following manner (see FIG. 3). In this manner, amount information A is associated with point A, amount information B is associated with point B, amount information C is associated with point C, amount information D is associated with point D, amount information E is associated with point E, amount information F is associated with point F, amount information G is associated with point G, amount information H is associated with point H, amount information I is associated with point I, and amount information J is associated with point J.

[0069] According to this configuration, as the habitat situation of the yamame, the first aquatic organism, at points A to J of the river, when March 1, 2024 of the first collection period is selected, March 1, 2024 of the first collection period can be the display target (see FIG. 1). When May 1, 2024 of the second collection period is selected, May 1, 2024 of the second collection period can be the display target (see FIG. 2). When July 1, 2024 of the third collection period is selected, July 1, 2024 of the third collection period can be the display target (see FIG. 3). For example, it is presumed that the habitat range of the yamame, the first aquatic organism, has moved from point B to other points (for example, refer to points A, C, D) in the river during the two months from March 1, 2024 of the first collection period to May 1, 2024 of the second collection period (see FIGS. 1, 2, 7). By switching the display target from March 1, 2024 of the first collection period to May 1, 2024 of the second collection period, viewers can be made to recognize the change in the habitat range of the yamame, the first aquatic organism.

[0070] (3) The program for the representation process causes the processor 11 to execute a process of acquiring first aquatic organism information when a yamame, which is a first aquatic organism, is received by the operating device 16, a process of acquiring second aquatic organism information when a iwana, which is a second aquatic organism, is received by the operating device 16, and a process of acquiring third aquatic organism information when an ajime-dojo, which is a third aquatic organism, is received by the operating device 16 (refer to S11, S15: Yes in FIG. 10).

[0071] It targets March 1, 2024, which is the first collection period. The process executed in S13 of FIG. 10, when the first aquatic organism information is acquired, causes the amount information A - J corresponding to the amount of environmental DNA for each of the points A - J associated with the first collection information and the position information A - J in the first aquatic organism table to be displayed together with a map image in the following manner (refer to FIG. 1). When the second aquatic organism information is acquired, the amount information A - J corresponding to the amount of environmental DNA for each of the points A - J associated with the first collection information and the position information A - J in the second aquatic organism table is displayed together with a map image in the following manner (refer to FIG. 4). When the third aquatic organism information is acquired, the amount information A - J corresponding to the amount of environmental DNA for each of the points A - J associated with the first collection information and the position information A - J in the third aquatic organism table is displayed together with a map image in the following manner (refer to FIG. 5). This manner associates amount information A with point A, amount information B with point B, amount information C with point C, amount information D with point D, amount information E with point E, amount information F with point F, amount information G with point G, amount information H with point H, amount information I with point I, and amount information J with point J.

[0072] According to this configuration, when the yamame, which is the first aquatic organism, is selected, the habitat status of the yamame, which is the first aquatic organism, can be displayed. When the iwana, which is the second aquatic organism, is selected, the habitat status of the iwana, which is the second aquatic organism, can be displayed. When the ajime-dojo, which is the third aquatic organism, is selected, the habitat status of the ajime-dojo, which is the third aquatic organism, can be displayed.

Hereinafter, the differences from the above will be described, and the descriptions of the same points will be omitted 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 including multiple months. Examples of periods including multiple months are "January to March, April to June, July to September, October to December" and "January to June, July to December". The number of months specifying one period, the start month, and the end month of one period are appropriately set in consideration of various conditions. The sampling period may include an element of time in addition to year, month, and day. Examples of the element of time are "morning or afternoon", "hour", and "hour and minute".

[0077] (2) In the display process, the processor 11 generates map data incorporating quantity information A to J according to the following combinations of aquatic organism information and sampling information, and causes the map image to be displayed on the display device 15 (see S13 in FIG. 10 and FIGS. 1 to 5). This aquatic organism information is any one of the first aquatic organism information, the second aquatic organism information, and the third aquatic organism information acquired in S11 or updated in S21. This sampling information is any one of the first sampling information, the second sampling information, and the third sampling information acquired in S11 or updated in S17. In this description, the combination of the above-mentioned aquatic organism information and sampling information is also referred to as the "combination of aquatic organism information and sampling information".

[0078] In the display process, the generation of map data according to the combination of aquatic organism information and sampling information may be omitted. In this case, map data incorporating quantity information A to J is generated in advance for all combinations (a total of 9 combinations) of the first aquatic organism information, the second aquatic organism information, and the third aquatic organism information and the first sampling information, the second sampling information, and the third sampling information. The storage device 12 stores these 9 pieces of map data. The storage destination in the storage device 12 may be the storage 14. The 9 pieces of map data are registered in the display process program.

[0079] In this description, it is assumed that the storage 14 stores nine pieces of map data. For the sake of convenience of explanation, the nine pieces of map data are referred to as "first map data" to "ninth map data". The first map data corresponds to the combination of the first aquatic organism information and the first collection information (see FIG. 1).

The display device 15 displays a map image represented by the fourth map data in the map area 22 of the operation screen 20. Assume that the combination of the aquatic organism information and the collection information is the second aquatic organism information and the second collection information (not shown). In this case, at S13 in Fig. 10, the processor 11 reads the fifth map data from the storage 14 into the main memory 13, and outputs an instruction to display the fifth map data stored in the main memory 13 to the display device 15. The display device 15 displays a map image represented by the fifth map data in the map area 22 of the operation screen 20. Assume that the combination of the aquatic organism information and the collection information is the second aquatic organism information and the third collection information (not shown). In this case, at S13 in Fig. 10, the processor 11 reads the sixth map data from the storage 14 into the main memory 13, and outputs an instruction to display the sixth map data stored in the main memory 13 to the display device 15. The display device 15 displays a map image represented by the sixth map data in the map area 22 of the operation screen 20.

[0082] Assume that the combination of the aquatic organism information and the collection information is the third aquatic organism information and the first collection information (see Fig. 4). In this case, at S13 in Fig. 10, the processor 11 reads the seventh map data from the storage 14 into the main memory 13, and outputs an instruction to display the seventh map data stored in the main memory 13 to the display device 15. The display device 15 displays a map image represented by the seventh map data in the map area 22 of the operation screen 20. Assume that the combination of the aquatic organism information and the collection information is the third aquatic organism information and the second collection information (not shown).

The display device 15 displays a map image represented by the ninth map data in the map area 22 of the operation screen 20.

[0083] (3) In the display process (see FIG. 10), the map image is displayed on the display device 15 (see S13 in FIG. 10 and FIGS. 1 to 5).

The quantity information has a form of a combination of circular figures having the following numerical values and the following areas. This numerical value indicates the amount of environmental DNA. This area has a certain relationship with the amount of environmental DNA. An example of the certain relationship is direct proportionality. Further, when the amount of environmental DNA is 0, this area is set to a predetermined constant value.
