Description

Technical Field

[0001] This invention relates to the field of stock enhancement and release technology, and in particular to a method for stock enhancement and release of large fish broodstock. Background Technology

[0002] With the increasing importance of protecting aquatic biodiversity and the sustainable management of aquatic ecosystems, stock enhancement has become a crucial means of protecting and restoring large fish populations. However, the stock enhancement process for large fish faces a series of technical challenges. Large fish have unique habits and demanding environmental requirements. Traditional stock enhancement methods lack a comprehensive understanding of large fish populations' information, habits, and optimal living conditions, making it impossible to provide suitable temporary holding environments and release conditions. Traditional methods also lack means to monitor the adaptation of large fish in temporary holding environments in real time, making it difficult to accurately assess their adaptability and health status. This limits the accuracy and reliability of pre-release parent stock selection and post-release survival assessment. Therefore, a method for stock enhancement of large fish parents is needed to address these issues and improve the efficiency and success rate of large fish stock enhancement. Summary of the Invention

[0003] To address at least one of the aforementioned technical problems, this invention proposes a method for the propagation and release of large fish parent stock.

[0004] The first aspect of this invention provides a method for releasing large fish broodstock, comprising:

[0005] Obtain information about large fish species, including their names, habits, and optimal living conditions.

[0006] Adjust the temporary holding environment conditions according to the fish information;

[0007] Image recognition technology is used to monitor the adaptation of large fish to temporary holding environments in real time.

[0008] Based on the aforementioned adaptation, assess whether large fish species meet the conditions for stock enhancement and release, and generate a release assessment report.

[0009] Based on the release assessment report, a stock enhancement and release plan was formulated, and the survival status of the corresponding large fish species was tracked according to the plan.

[0010] In this solution, the acquisition of fish information for large fish includes the fish name and fish habits, specifically:

[0011] Obtain the names of the large fish species that need to be released for propagation;

[0012] Search the internet for the living habits of large fish species based on their names;

[0013] Obtain the first environmental information for the large fish species to be released for propagation, including water temperature, water oxygen content, food quantity, and water quality;

[0014] The names, habits, and primary environmental information of the large fish species are used to construct fish life information.

[0015] In this plan, adjusting the temporary holding environment conditions based on the fish information specifically includes:

[0016] Second environmental information of the temporary holding environment for large fish is obtained through sensor devices. The second environmental information includes water temperature, water oxygen content, food quantity, and water quality.

[0017] The first environmental information is compared with the second environmental information. The second environmental information is divided into 10 levels of conditions, and the temporary holding environment conditions are adjusted level by level according to a preset cycle.

[0018] Underwater monitoring equipment is used to obtain the real-time first activity level of large fish in their original environment. The first activity level information includes the first level of movement activity and the first respiratory rate.

[0019] In this solution, the real-time monitoring of the adaptation of large fish to the temporary holding environment using image recognition technology specifically includes:

[0021] Based on the video image data, obtain video frame images within a preset time period, and preprocess the video frame images;

[0022] Fish identification is performed on each preprocessed video frame to extract images of large fish from each video frame.

[0023] Large fish images are imported into an image recognition system to identify the same fish in each frame of video images and mark the same fish in each frame of video images to obtain a set of marked images.

[0024] By analyzing the activity trajectories of continuous labeled images, the second level of movement activity of large fish in the temporary holding environment was obtained;

[0025] Based on the identification and statistics of the labeled images, the gill bone activity frequency of the same fish parent was calculated, and the second respiratory frequency was obtained through the gill bone activity frequency;

The adaptation status includes the adaptation status of large fish to the temporary holding environment and the stress status of large fish.

[0028] In this plan, the step of assessing whether large fish species meet the conditions for stock enhancement and release based on their adaptation status, and generating a release assessment report, specifically involves:

Otherwise, the adaptation status is determined to be unsatisfactory, and an adaptation report is generated.

[0030] Based on the adaptation report, assess whether the large fish species meet the conditions for stock enhancement and release.

[0031] Within a preset time period, with a one-day recording interval, the adaptation of large fish to the temporary holding environment is recorded, forming a time-adaptation curve.

[0032] The optimal time period for large fish to adapt to the temporary holding environment was analyzed based on the time-adaptation curve.

[0035] A predetermined percentage of large fish species are selected for behavioral monitoring to obtain monitoring results, which include the activity level and stress status of the large fish species.

[0036] Based on a comprehensive analysis of the adaptation of large fish to the temporary holding environment and monitoring results within 24 hours, the optimal time for stock enhancement and release within one day was determined.

[0037] Based on the optimal timing for restocking and the restocking assessment report, a parent stocking plan was developed.

[0038] In this plan, the step of formulating a stock enhancement and release plan based on the release assessment report, and tracking the survival status of the corresponding large fish released according to the stock enhancement and release plan, specifically includes:

[0039] Based on the release assessment report, a restocking plan is formulated, which includes the release location, the number of fish to be released, the release time, and the release method.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0079] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0080] Figure 1 A flowchart of a method for propagating and releasing large fish parents according to the present invention is shown.

[0081] like Figure 1 As shown, the first aspect of the present invention provides a method for releasing large fish broodstock, comprising:

[0082] S102, Obtain fish information of large fish, including the name of the large fish, its living habits, and optimal living conditions;

[0083] S104, Adjust the temporary holding environment conditions according to the fish information;

[0084] S106 uses image recognition technology to monitor the adaptation of large fish in temporary holding environments in real time.

[0085] S108, Based on the aforementioned adaptation, assess whether large fish species meet the conditions for stock enhancement and release, and generate a release assessment report;

[0086] S110, Based on the release assessment report, formulate a stock enhancement and release plan, and track the survival status of the corresponding large fish species released according to the stock enhancement and release plan.

[0087] According to an embodiment of the present invention, the acquisition of fish information of large fish, the fish information including fish name and fish living habits, specifically includes:

[0088] Obtain the names of the large fish species that need to be released for propagation;

[0089] Search the internet for the living habits of large fish species based on their names;

[0092] It should be noted that the first environmental information refers to the environmental information of the waters where large fish are released for stock enhancement; the living habits include the habits, behaviors, and habitat preferences of the large fish; the fish information can be used for the formulation and management of the stock enhancement plan to ensure the suitable survival and reproduction of large fish.

[0093] According to an embodiment of the present invention, adjusting the temporary holding environment conditions based on the fish information specifically includes:

[0094] Second environmental information of the temporary holding environment for large fish is obtained through sensor devices. The second environmental information includes water temperature, water oxygen content, food quantity, and water quality.

[0095] The first environmental information is compared with the second environmental information. The second environmental information is divided into 10 levels of conditions, and the temporary holding environment conditions are adjusted level by level according to a preset cycle.

[0096] Underwater monitoring equipment is used to obtain the real-time first activity level of large fish in their original environment. The first activity level information includes the first level of movement activity and the first respiratory rate.

[0097] It should be noted that the sensor equipment includes temperature sensors, oxygen sensors, and water quality sensors. These sensors are installed in the temporary holding area to monitor and record the temporary holding environmental conditions in real time. The process of dividing the second environmental information into 10 levels specifically involves comparing the water temperature, water oxygen content, and food quantity in the second environmental information with those in the first environmental information, calculating the difference between the two, dividing the difference by 10 to obtain the average condition level, and then progressively increasing the average condition level for each level until the second environmental condition reaches the first environmental condition. According to the classified conditions, the temporary holding environment conditions are adjusted step by step according to a preset cycle. Within a certain time interval, the water temperature, water oxygen content, food quantity, and water quality parameters are gradually changed so that the large fish can gradually adapt to the temporary holding environment and thus adapt to the environment after the release. The respiratory frequency is the activity frequency of the gill bones of the large fish. The respiratory frequency is obtained by monitoring and calculating the activity frequency of the gill bones of the large fish. The monitoring involves acquiring video images of the fish within one minute, determining the number of gill closure and closure cycles of the large fish, and evaluating the respiratory frequency based on the number of gill closure and closure cycles.

[0103] S208, Import images of large fish into the image recognition system, recognize the images of large fish, identify the same fish in each frame of video image, and mark the same fish in each frame of video image to obtain a marked image set;

[0104] S210, by analyzing the activity trajectory of continuous labeled images, the second level of movement activity of large fish in the temporary holding environment is obtained;

[0105] S212, Identify and count the gill bone activity frequency of the same parent fish based on the marked image, and obtain the second respiratory frequency through the gill bone activity frequency;

[0106] S214, integrate the second level of motor activity and the second respiratory rate into second activity information;

[0107] S216, compare and analyze the first activity level information with the second activity level information to obtain the adaptation status of large fish in the temporary holding environment. The adaptation status includes the adaptation status of large fish to the temporary holding environment and the stress status of large fish.

[0108] It should be noted that the original environment refers to the breeding site of large fish; the preset time period is one week; the constructed image recognition system consists of camera equipment and target detection algorithm; the preprocessing includes noise reduction, brightness and contrast adjustment; through image processing and segmentation techniques, images of large fish can be extracted from the preprocessed video frame images; the gill bone activity frequency is determined by identifying and judging the number of gill bone closure and closure cycles within one minute, and by using image recognition technology to determine the gill bone closure and closure of large fish; real-time monitoring of the adaptation of large fish in the temporary holding environment through image recognition technology can provide important data and indicators to assess the health status, adaptability and stress response of fish, which helps to adjust the temporary holding environment conditions in a timely manner and improve the survival and reproductive success rate of large fish; the labeled image set is a labeled image set obtained by labeling each frame of video image.

[0109] Figure 3 The flowchart for generating a release assessment report according to the present invention is shown.

[0110] According to an embodiment of the present invention, the step of assessing whether large fish species meet the conditions for stock enhancement and release based on the adaptation status, and generating a release assessment report, specifically includes:

[0111] S302, based on the adaptation status, if the second level of activity of the large fish is less than or equal to the first level of activity of the large fish, and the second level of activity of the large fish is greater than the preset level of activity, and the second respiratory rate of the large fish is less than or equal to the respiratory rate, and the second respiratory rate is greater than the preset respiratory rate, then the adaptation status is determined to be good; otherwise, the adaptation status is determined to be unsatisfactory, and an adaptation report is generated.

[0112] S304, Based on the aforementioned adaptation report, assess whether large fish species meet the conditions for stock enhancement and release;

[0113] S306, within a preset time period, records the adaptation of large fish in a temporary holding environment at one-day intervals, forming a time-adaptation curve.

[0114] S308, Based on the time-adaptation curve, the optimal time period for the adaptation of large fish in the temporary holding environment is analyzed;

[0115] S310, the optimal time period for the adaptation of large fish in the temporary holding environment is taken as the optimal time period for stock enhancement and release, and a release assessment report is generated. The release assessment report includes whether the large fish meet the conditions for stock enhancement and release and the optimal time period for stock enhancement and release.

[0116] S312, obtain the adaptation status of large fish in the temporary holding environment within 24 hours;

[0117] S314, A preset percentage of large fish are selected for behavioral monitoring to obtain monitoring results, including the activity level and stress status of the large fish.

[0118] S316. Based on a comprehensive analysis of the adaptation of large fish in the temporary holding environment and monitoring results within 24 hours, the optimal time for stock enhancement and release within one day was determined.

[0119] S318, based on the optimal time for stock enhancement and release and the release assessment report, a parent stocking plan is formulated.

[0120] It should be noted that the conditions for stock enhancement and release refer to the large fish adapting well to the temporary holding environment without experiencing stress. The time-adaptation curve is a record of the adaptation of large fish over a preset time period and visualized as a time-adaptation curve. The curve helps analysts understand the changing trend of the adaptation of large fish in the temporary holding environment. The adaptation of large fish in the temporary holding environment changes over time. The better the adaptation of large fish to the temporary holding environment, the lower the health damage to large fish after stock enhancement and release, and therefore the better the adaptability to the stock enhancement and release environment. If the second level of kinetic activity of large fish is less than or equal to the first level of kinetic activity, and the second level of kinetic activity is greater than the preset level of activity, and the second respiratory rate of large fish is less than or equal to the respiratory rate, and the second respiratory rate is greater than the preset respiratory rate, then the adaptation is considered good. The parent stocking scheme helps reduce the stress response of the parent fish and avoids the stress of the parent fish causing harm to the release personnel.

[0121] According to an embodiment of the present invention, the step of formulating a stock enhancement and release plan based on the release assessment report, and tracking the survival status of the corresponding large fish species released according to the stock enhancement and release plan, specifically includes:

[0122] Based on the release assessment report, a restocking plan is formulated, which includes the release location, the number of fish to be released, the release time, and the release method.

[0123] According to the release plan, the survival status of large fish after the release is tracked in real time using tracking equipment. The survival status includes the location of the large fish and their number within a preset range.

[0124] The released population is sampled and tested regularly to obtain test results, which include physiological indicators and growth status.

[0125] The effectiveness of the restocking program is determined by analyzing and evaluating the survival status and test results, and the restocking strategy is adjusted accordingly.

[0126] It should be noted that the aforementioned stock enhancement and release program determines the release location, quantity, timing, and method. The selection of the release location is based on the research objectives and stock enhancement goals. The determination of the quantity is based on a comprehensive consideration of ecological balance, population growth goals, and resource sustainability factors. The timing of the release depends on the biological characteristics of the fish. The release methods include direct and indirect release. A scientifically sound stock enhancement and release program can ensure maximum release effectiveness and minimize adverse impacts on the natural environment. The tracking equipment includes underwater imaging equipment and fish tracking devices mounted on the fins. By monitoring and recording the survival of the fish, the release effectiveness can be assessed and necessary management measures can be taken. The sampling and testing are conducted to understand the health status and growth of the released population. Regular sampling and testing of the released population includes assessments of physiological indicators and growth. The obtained test results can provide insights into the fish's adaptability, survival status, and growth.

[0127] According to an embodiment of the present invention, it further includes:

[0128] The transportation environment of large fish is obtained, and the transportation environment is pre-processed. The pre-processing includes using partitions to divide the transportation vehicle to form a transportation space, and adding buffer devices at the edges of the transportation space.

[0129] Search the internet for the optimal transport environment for large fish, including transport temperature and pH value;

[0130] Adjust the transportation environment conditions according to the optimal transportation environment;

[0131] Obtain basic information about the large fish to be transported, including the size and weight of the large fish;

[0132] Based on the aforementioned basic information, large fish are classified and placed in different transport spaces;

[0133] Based on the aforementioned basic information, appropriate amounts of sodium barbital and food are placed in the transport space.

[0134] It should be noted that, according to the embodiments of the present invention, large fish can be temporarily anesthetized during transportation, reducing stress in the transportation environment and preventing large fish from being harmed during transportation.

[0135] According to an embodiment of the present invention, it further includes:

[0136] Historical environmental data of the stock enhancement and release area and historical fish monitoring data of the stock enhancement and release area were obtained. The historical environmental data included weather conditions, temperature, and air pressure.

[0137] A fish activity prediction model was constructed, and historical environmental data of the stock enhancement and release area and historical fish monitoring data of stock enhancement and release were imported into the fish activity prediction model for training.

[0138] Acquire real-time environmental data along the route of transporting large fish to the target area;

[0139] The real-time environmental data along the route is imported into the fish activity prediction model to predict fish activity and obtain the prediction results.

[0140] Based on the prediction results, the transportation environment conditions are adjusted in real time to generate a transportation environment adjustment plan.

[0141] It should be noted that, according to the embodiments of the present invention, the conditions of the transportation environment are adjusted in real time to maintain the activity of large fish in the transportation environment and avoid the large fish from losing activity or dying during transportation.

[0142] According to embodiments of the present invention, it further includes:

[0143] Obtain the length information of the target river for the large fish stocking program, and divide the target river into upper, middle and lower reaches based on the length information.

[0144] The underwater robot was used to monitor and obtain information on the types and numbers of fish in its own area in the upper, middle and lower reaches.

[0145] Statistical analysis based on fish species and fish population size yields the ratio of adult to juvenile fish and the fish population richness in the upper, middle and lower reaches of the river.

[0146] Based on the ratio of adult to juvenile fish and the fish population richness, the ecological environment of the upper, middle and lower reaches of the river is assessed, and an ecological environment assessment report is generated.

[0147] A regional ecological imbalance report is generated based on the aforementioned ecological environment assessment report;

[0148] By comparing reports on the degree of regional ecological imbalance in the upper, middle and lower reaches, a priority plan for stock enhancement and release areas is generated, and a plan for the fish species to be released is generated based on the reports on the degree of regional ecological imbalance.

[0149] It should be noted that, according to the embodiments of the present invention, it is possible to determine which area of ​​the river has more severe ecological damage, and then to first carry out stock enhancement and release in that area. The species and quantity of fish to be released are determined according to the release plan, thereby achieving rapid restoration of the ecological environment. The embodiments of the present invention divide the target river for stock enhancement and release into different areas, and assess the ecology of each area to generate a priority plan for stock enhancement and release areas. Stock enhancement and release are prioritized in areas where the ecological environment is more severely damaged, further restoring the river's ecological environment in those areas. The underwater robot monitoring is achieved by acquiring fish images of the river area through camera equipment and performing statistical analysis.

[0167] It should be noted that the sensor equipment includes temperature sensors, oxygen sensors, and water quality sensors. These sensors are installed in the temporary holding area to monitor and record the temporary holding environmental conditions in real time. The process of dividing the second environmental information into 10 levels specifically involves comparing the water temperature, water oxygen content, and food quantity in the second environmental information with those in the first environmental information, calculating the difference between the two, dividing the difference by 10 to obtain the average condition level, and then progressively increasing the average condition level for each level until the second environmental condition reaches the first environmental condition. According to the classified conditions, the temporary holding environment conditions are adjusted step by step according to a preset cycle. Within a certain time interval, the water temperature, water oxygen content, food quantity, and water quality parameters are gradually changed so that the large fish can gradually adapt to the temporary holding environment and thus adapt to the environment after the release. The respiratory frequency is the activity frequency of the gill bones of the large fish. The respiratory frequency is obtained by monitoring and calculating the activity frequency of the gill bones of the large fish. The monitoring involves acquiring video images of the fish within one minute, determining the number of gill closure and closure cycles of the large fish, and evaluating the respiratory frequency based on the number of gill closure and closure cycles.

[0168] According to an embodiment of the present invention, the real-time monitoring of the adaptation of large fish to the temporary holding environment using image recognition technology specifically includes:

[0169] Build an image recognition system to acquire real-time video image data of large fish in temporary holding environments;

[0170] Based on the video image data, obtain video frame images within a preset time period, and preprocess the video frame images;

[0171] Fish identification is performed on each preprocessed video frame to extract images of large fish from each video frame.

[0172] Large fish images are imported into an image recognition system to identify the same fish in each frame of video images and mark the same fish in each frame of video images to obtain a set of marked images.

[0173] By analyzing the activity trajectories of continuous labeled images, the second level of movement activity of large fish in the temporary holding environment was obtained;

[0174] Based on the identification and statistics of the labeled images, the gill bone activity frequency of the same fish parent was calculated, and the second respiratory frequency was obtained through the gill bone activity frequency;

[0175] The second level of motor activity and the second respiratory rate are integrated into the second level of activity information;

[0176] By comparing and analyzing the first activity level information with the second activity level information, the adaptation status of large fish in the temporary holding environment can be obtained. The adaptation status includes the adaptation status of large fish to the temporary holding environment and the stress status of large fish.

[0177] It should be noted that the original environment refers to the breeding site of large fish; the preset time period is one week; the constructed image recognition system consists of camera equipment and target detection algorithm; the preprocessing includes noise reduction, brightness and contrast adjustment; through image processing and segmentation techniques, images of large fish can be extracted from the preprocessed video frame images; the gill bone activity frequency is determined by identifying and judging the number of gill bone closure and closure cycles within one minute, and by using image recognition technology to determine the gill bone closure and closure of large fish; real-time monitoring of the adaptation of large fish in the temporary holding environment through image recognition technology can provide important data and indicators to assess the health status, adaptability and stress response of fish, which helps to adjust the temporary holding environment conditions in a timely manner and improve the survival and reproductive success rate of large fish; the labeled image set is a labeled image set obtained by labeling each frame of video image.

[0178] According to an embodiment of the present invention, the step of assessing whether large fish species meet the conditions for stock enhancement and release based on the adaptation status, and generating a release assessment report, specifically includes:

[0179] Based on the adaptation status, if the second level of activity of the large fish is less than or equal to the first level of activity, and the second level of activity is greater than the preset level of activity, and the second respiratory rate of the large fish is less than or equal to the respiratory rate, and the second respiratory rate is greater than the preset respiratory rate, then the adaptation status is determined to be good. Otherwise, the adaptation status is determined to be unsatisfactory, and an adaptation report is generated.

[0180] Based on the adaptation report, assess whether the large fish species meet the conditions for stock enhancement and release.

[0181] Within a preset time period, with a one-day recording interval, the adaptation of large fish to the temporary holding environment is recorded, forming a time-adaptation curve.

[0182] The optimal time period for large fish to adapt to the temporary holding environment was analyzed based on the time-adaptation curve.

[0183] The optimal time period for stock enhancement and release is determined by observing the best adaptation of large fish to the temporary holding environment, and a release assessment report is generated. The release assessment report includes whether the large fish meet the conditions for stock enhancement and release and the optimal time period for stock enhancement and release.

[0184] To obtain information on the adaptation of large fish to the temporary holding environment within 24 hours;

[0185] A predetermined percentage of large fish species are selected for behavioral monitoring to obtain monitoring results, which include the activity level and stress status of the large fish species.

[0186] Based on a comprehensive analysis of the adaptation of large fish to the temporary holding environment and monitoring results within 24 hours, the optimal time for stock enhancement and release within one day was determined.

[0187] Based on the optimal timing for restocking and the restocking assessment report, a parent stocking plan was developed.

[0188] It should be noted that the conditions for stock enhancement and release refer to the large fish adapting well to the temporary holding environment without experiencing stress. The time-adaptation curve is a record of the adaptation of large fish over a preset time period and visualized as a time-adaptation curve. The curve helps analysts understand the changing trend of the adaptation of large fish in the temporary holding environment. The adaptation of large fish in the temporary holding environment changes over time. The better the adaptation of large fish to the temporary holding environment, the lower the health damage to large fish after stock enhancement and release, and therefore the better the adaptability to the stock enhancement and release environment. If the second level of kinetic activity of large fish is less than or equal to the first level of kinetic activity, and the second level of kinetic activity is greater than the preset level of activity, and the second respiratory rate of large fish is less than or equal to the respiratory rate, and the second respiratory rate is greater than the preset respiratory rate, then the adaptation is considered good. The parent stocking scheme helps reduce the stress response of the parent fish and avoids the stress of the parent fish causing harm to the release personnel.

[0189] According to an embodiment of the present invention, the step of formulating a stock enhancement and release plan based on the release assessment report, and tracking the survival status of the corresponding large fish species released according to the stock enhancement and release plan, specifically includes:

[0190] Based on the release assessment report, a restocking plan is formulated, which includes the release location, the number of fish to be released, the release time, and the release method.

[0191] According to the release plan, the survival status of large fish after the release is tracked in real time using tracking equipment. The survival status includes the location of the large fish and their number within a preset range.

[0192] The released population is sampled and tested regularly to obtain test results, which include physiological indicators and growth status.

[0193] The effectiveness of the restocking program is determined by analyzing and evaluating the survival status and test results, and the restocking strategy is adjusted accordingly.

[0194] It should be noted that the aforementioned stock enhancement and release program determines the release location, quantity, timing, and method. The selection of the release location is based on the research objectives and stock enhancement goals. The determination of the quantity is based on a comprehensive consideration of ecological balance, population growth goals, and resource sustainability factors. The timing of the release depends on the biological characteristics of the fish. The release methods include direct and indirect release. A scientifically sound stock enhancement and release program can ensure maximum release effectiveness and minimize adverse impacts on the natural environment. The tracking equipment includes underwater imaging equipment and fish tracking devices mounted on the fins. By monitoring and recording the survival of the fish, the release effectiveness can be assessed and necessary management measures can be taken. The sampling and testing are conducted to understand the health status and growth of the released population. Regular sampling and testing of the released population includes assessments of physiological indicators and growth. The obtained test results can provide insights into the fish's adaptability, survival status, and growth.

[0200] Based on the aforementioned basic information, large fish are classified and placed in different transport spaces;

[0201] Based on the aforementioned basic information, appropriate amounts of sodium barbital and food are placed in the transport space.

[0202] It should be noted that, in the embodiments of the present invention, large fish can be temporarily anesthetized during transportation, reducing stress in the transportation environment and preventing damage to large fish during transportation.

[0208] Based on the prediction results, the transportation environment conditions are adjusted in real time to generate a transportation environment adjustment plan.

[0209] It should be noted that real-time control of the transportation environment is necessary to maintain the activity of large fish during transportation and prevent them from becoming less active or dying during the process.

[0210] According to embodiments of the present invention, it further includes:

[0211] Obtain the length information of the target river for the large fish stocking program, and divide the target river into upper, middle and lower reaches based on the length information.

[0213] Statistical analysis based on fish species and fish population size yields the ratio of adult to juvenile fish and the fish population richness in the upper, middle and lower reaches of the river.

[0214] Based on the ratio of adult to juvenile fish and the fish population richness, the ecological environment of the upper, middle and lower reaches of the river is assessed, and an ecological environment assessment report is generated.

[0215] A regional ecological imbalance report is generated based on the aforementioned ecological environment assessment report;

[0216] By comparing reports on the degree of regional ecological imbalance in the upper, middle and lower reaches, a priority plan for stock enhancement and release areas is generated, and a plan for the fish species to be released is generated based on the reports on the degree of regional ecological imbalance.

[0217] It should be noted that, according to the embodiments of the present invention, it is possible to determine which area of ​​the river has more severe ecological damage, and then to first carry out stock enhancement and release in that area. The species and quantity of fish to be released are determined according to the release plan, thereby achieving rapid restoration of the ecological environment. The embodiments of the present invention divide the target river for stock enhancement and release into different areas, and assess the ecology of each area to generate a priority plan for stock enhancement and release areas. Stock enhancement and release are prioritized in areas where the ecological environment is more severely damaged, further restoring the river's ecological environment in those areas. The underwater robot monitoring is achieved by acquiring fish images of the river area through camera equipment and performing statistical analysis.
