Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0051] It should be noted that the "at..." in the embodiments of the present application can be the instant when a certain situation occurs, or can be a period of time after a certain situation occurs, and the embodiments of the present application do not specifically limit this. In addition, the prediction method of the emergence time and the opening time provided in the embodiments of the present application is only used as an example, and the prediction method of the emergence time and the opening time can also include more or less content.

[0052] In order to clearly describe the technical solutions of the embodiments of the present application, some terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0053] Emergence time: refers to the time from fertilization to hatching.

[0054] Opening time: refers to the time from fertilization to exogenous feeding.

[0055] Coefficient of determination (R 2 ): Also known as the coefficient of determination, coefficient of determination or index of determination, it is used to reflect the degree of explanation of the regression model for the changes in the dependent variable. The coefficient of determination is expressed as the ratio between the regression sum of squares and the total sum of squares of deviations, which is equal to the square of the correlation coefficient. The range of the coefficient of determination is between 0 and 1. The larger the value, the higher the proportion of the model's explanation of the dependent variable and the better the model's fit. On the contrary, if the value of the coefficient of determination is small, then the model's explanation of the dependent variable is low and the model's fit is poor.

[0056] In the breeding process, the time of fish emergence and opening is often predicted based on experience, which is not very accurate and makes it difficult to prepare for the transfer and cultivation of fry in advance, resulting in a backlog of fry and the death of fry. Accurately estimating the time of fish emergence and opening can reduce fry mortality, improve breeding efficiency, and promote the construction of sustainable artificial fish populations.

[0057] Inaccurate estimation of the emergence time and the opening time can easily lead to the death of the seedlings, which is a problem that the present invention urgently needs to solve.

[0058] Based on this, the embodiments of the present application provide a method, device, equipment and storage medium for predicting emergence time and opening time, which can be used in the field of fish farming technology, aiming to solve the above technical problems of the prior art.

Furthermore, the multiple breeding temperatures can be 16°C, 19°C and 22°C, or more other temperatures.

[0062] S102, establishing a regression equation group according to the duration sample table;

[0063] Specifically, the regression equation group is used to indicate the relationship between the predicted time for emergence and the predicted time for opening, and each breeding temperature; the breeding temperature and time data of the experimental group are analyzed to obtain the regression equations of the predicted time for emergence and the predicted time for opening and the temperature, respectively.

[0064] S103, according to the regression equation group, obtain the seedling emergence percentage and development index table;

[0065] Specifically, the emergence percentage is used to indicate the ratio of the predicted emergence time to the predicted opening time, and the development index table is used to indicate the degree of development corresponding to each environmental temperature within a unit time; according to the regression equations of the predicted emergence time and the predicted opening time and temperature respectively, the ratio of the predicted emergence time to the predicted opening time and the development index corresponding to each environmental temperature within a unit time are obtained.

[0066] S104, according to the germination percentage and development index table, obtain the target fish's opening prediction time and germination prediction time;

[0067] Specifically, according to the unit length of time in the future and the development index corresponding to the corresponding ambient temperature, the sum of the development indexes corresponding to the ambient temperature of the target fish in the future is accumulated, and then the predicted opening time and the predicted emergence time are determined according to the emergence percentage and the sum of the development indexes.

[0068] In a possible design, after S103, the method further includes: tracing back the emergence time of the target fish according to the emergence percentage, the development index table and the actual opening time of the target fish;

[0069] Specifically, according to the actual opening time of the target fish, the development index table is looked up to obtain the unit length of time before the opening time, the corresponding development index of the corresponding ambient temperature, and then the emergence time and fertilization time of the target fish are obtained.

[0070] The present application provides a method for predicting the emergence time and the opening time of fish, by obtaining a time sample table, wherein the time sample table includes: a preset number of breeding temperatures, and the emergence sample time and the opening sample time of each sample fish at each breeding temperature; according to the time sample table, a regression equation group is established, wherein the regression equation group is used to indicate the relationship between the emergence prediction time and the opening prediction time, respectively, and each breeding temperature; according to the regression equation group, a germination percentage and a development index table are obtained, wherein the germination percentage is used to indicate the ratio of the emergence prediction time to the opening prediction time, and the development index table is used to indicate the development degree corresponding to each environmental temperature within a unit time; according to the germination percentage and the development index table, the opening prediction time and the emergence prediction time of the target fish are obtained. The following technical effects are achieved: by establishing a regression equation group based on the time sample table, and obtaining the germination percentage and development index table based on the regression equation group, the problem of inaccurate estimation of the germination time and the opening time, which easily causes the death of the seedlings, is solved; by obtaining the predicted opening time and germination time of the target fish based on the germination percentage and the development index table, the problem of low efficiency in estimating the germination time and the opening time is solved.

[0071] Figure 2A schematic diagram of a method for predicting emergence time and opening time provided in an embodiment of the present application Figure 2 In this embodiment Figure 1 Based on the embodiment, the prediction method of the emergence time and the opening time is described in detail. Figure 2 As shown, the method includes:

[0072] S201, obtaining a duration sample table;

[0073] Specifically, the duration sample table includes: a preset number of breeding temperatures, and the emergence sample duration and the opening sample duration of each sample fish under each breeding temperature; S201 is similar to S101 and will not be repeated in this embodiment.

[0074] S202, obtaining a functional relationship through correlation analysis according to the duration sample table; obtaining a regression equation system according to the functional relationship and the coefficient of determination;

[0075] Specifically, the coefficient of determination was determined based on the duration sample table; the regression equation group was used to indicate the relationship between the predicted duration of emergence and the predicted duration of opening, respectively, and each culture temperature;

[0076] First, the temperature and duration data of the experimental group are subjected to correlation analysis to obtain the functional relationship between temperature and the duration of emergence and the duration of opening, specifically including: using temperature as the horizontal axis and duration as the vertical axis, drawing the scatter plots corresponding to the duration of emergence and the duration of opening, and performing preliminary data fitting to obtain the functional relationship between the duration of emergence and the duration of opening and the temperature. Then, the data is processed, and optimization processing is performed according to the functional relationship and the coefficient of determination to obtain the regression equations of the duration of emergence and the duration of opening and the temperature. Further, the data can be processed by electronic spreadsheets (Microsoft Excel) and analysis software (Statistical Product and Service Solutions, SPSS). Further, the coefficient of determination can be pre-set according to the actual situation, and then the functional relationship can be optimized according to the coefficient of determination, and the sample can be divided into a prediction group and a verification group, and the regression equation group and the coefficient of determination are obtained from the data of the prediction group, and the obtained regression equation group is used for the verification group of the sample. If the duration of emergence and the duration of opening obtained according to the regression equation group do not match the actual duration, the coefficient of determination can be adjusted to adjust the regression equation group. Furthermore, the functional relationship obtained by the preliminary fitting is optimized. During data processing, the coefficient of determination and the test probability p value (p value) of the logarithmic function, system function (System Function, S function), growth function, exponential and inverse function are compared to determine the optimal regression equation.

[0077] S203, obtaining a seedling emergence percentage according to a seedling emergence equation and an opening equation; obtaining an opening prediction time corresponding to each ambient temperature according to the opening equation and a plurality of preset ambient temperatures;

[0078] Specifically, the regression equation group includes: emergence equation and opening equation; the emergence percentage is used to indicate the ratio of the predicted emergence time to the predicted opening time;

[0079] The germination percentage is obtained from the ratio of the germination equation to the opening equation. Since the ratio varies slightly with the ambient temperature, the germination percentage can be expressed in the form of mean ± standard deviation. The preset multiple ambient temperatures can be obtained by taking values ​​one by one in a certain temperature gradient within the range of the lowest to highest breeding temperature. Substituting the temperature into the opening equation, the opening prediction time corresponding to each ambient temperature is obtained.

[0080] S204, obtaining a development index table according to the opening prediction duration corresponding to each environmental temperature;

[0081] Specifically, the development index table is used to indicate the development degree corresponding to each environmental temperature within a unit time; the unit time can be 12 hours, one day, one week, etc. Taking one day as an example, first, the predicted opening time corresponding to each environmental temperature is divided by 24 to calculate the number of days required for exogenous feeding; secondly, 100% is divided by the predicted number of days to calculate the daily development index; finally, the daily development index corresponding to all environmental temperatures is integrated to obtain the development index table.

[0082] S205, obtaining a cumulative growth prediction table according to the growth index table and the ambient temperature at each preset time in a plurality of future preset time periods;

[0083] Specifically, taking one day as an example, starting from the day of fertilization, based on the average water temperature every day in the future, the development index table is looked up to obtain the daily development index, and for each day, the sum of the development indexes of the current day and all previous days is calculated to obtain the daily cumulative development index. The number of days, temperature, daily development index and daily cumulative development index are integrated to obtain a cumulative development prediction table.

[0084] S206. From at least one cumulative development percentage of not less than 100% in the cumulative development prediction table, the preset time corresponding to the minimum cumulative development percentage is used as the predicted opening time of the target fish; from multiple cumulative development percentages of not less than the emergence percentage in the cumulative development prediction table, the preset time corresponding to the minimum cumulative development percentage is used as the predicted emergence time of the target fish.

[0085] Specifically, the cumulative development prediction table includes: the cumulative development percentage of each preset time in multiple preset time periods in the future; taking one day as an example, find the cumulative development index of each day in the future in the cumulative development prediction table, determine the predicted date of emergence of the target fish based on the emergence percentage, and determine the predicted date of opening of the target fish based on 100%.

[0086] In one example, the unit time is calculated as one day, and the emergence time and mouth opening time of Yangtze sturgeon in three experimental groups of 16℃, 19℃ and 22℃ are recorded. Data processing is performed to compare logarithmic function, S function, growth function, exponential and inverse function. Logarithmic, S, growth, exponential function R 2 The values ​​are 0.996, 0.994, 0.997, and 0.997, respectively, which are all smaller than the inverse function R 2 The p value of the above five functions is less than 0.001, and the difference is significant. The emergence equation is: y = -56.67 + 3094.94 / X (R 2 =0.865); the opening equation is: y = -100.52 + 10005.46 / X (R 2 =0.998). Where X represents the daily average water temperature (°C), Y represents the development time (h), and the calculated seedling percentage is 24.49±1.40%.

[0087] Table 1

[0088]

[0089] Using the obtained regression equation, based on the daily average water temperature, the predicted opening duration was divided by 24, the number of days required for exogenous feeding was calculated, and the daily development index was calculated by dividing 100% by the predicted number of days to obtain the development index table. At a temperature of 14.0℃ to 25.9℃, the daily development index from the beginning of germination to exogenous feeding ranged from 3.91% to 8.40%, as shown in Table 1. Table 1 is a development index table of Yangtze sturgeon embryos at different water temperatures. If the daily average water temperature on a certain day is 14.1℃, the daily average water temperature (℃) is 14 and the decimal (℃) is 0.1 in Table 1, and the daily development index is 3.94%.

[0090] In one example, the unit time is calculated as one day, taking the spring breeding of a certain experimental station of the Yangtze River Sturgeon Research Institute as an example. The fertilization date of the Yangtze River sturgeon at a certain experimental station is April 11, 2023, the emergence date is April 15 (5 days after fertilization), and the exogenous feeding time is April 29 (14 days after emergence, 19 days after fertilization). According to the daily average temperature provided by a certain experimental station, the cumulative development prediction table is shown in Table 2, which is the cumulative development prediction table of a certain experimental station.

[0091] Table 2

[0092] Number of days Daily average water temperature (℃) Daily growth percentage (%) Cumulative development percentage (%) 1 17.0 4.92 4.92 2 17.5 5.09 10.01 3 17.5 5.09 15.10 4 17.9 5.24 20.34 5 17.9 5.24 25.57 6 18.0 5.27 30.84 7 18.0 5.27 36.12 8 18.2 5.34 41.46 9 18.4 5.41 46.87 10 18.8 5.56 52.43 11 18.9 5.60 58.03 12 19.0 5.63 63.66 13 19.0 5.63 69.29 14 19.1 5.67 74.96 15 19.1 5.67 80.63 16 19.2 5.71 86.34 17 19.2 5.71 92.04 18 19.3 5.74 97.79 19 19.3 5.74 103.53

[0093] Based on the actual average water temperature of a certain experimental station during the breeding day, according to the daily development index table, the cumulative development percentage of fertilized eggs on the 5th day of cultivation was calculated to be 25.57%, reaching the development percentage (24.49±1.40%); the cumulative development percentage on the 19th day was 103.53%, reaching the opening percentage (100%), and the inferred hatching time and opening time were the 5th day and the 19th day, respectively. The hatching and opening time of Yangtze sturgeon seedlings at a certain experimental station were actually the 5th day and the 19th day after fertilization, which was consistent with the predicted results.

[0094] The method provided in this embodiment obtains a time sample table, wherein the time sample table includes: a preset number of breeding temperatures, and the emergence sample time and the mouth opening sample time of each sample fish under each breeding temperature; according to the time sample table, a regression equation group is established, wherein the regression equation group is used to indicate the relationship between the emergence prediction time and the mouth opening prediction time, respectively, and each breeding temperature; according to the regression equation group, a germination percentage and a development index table are obtained, wherein the germination percentage is used to indicate the ratio of the emergence prediction time to the mouth opening prediction time, and the development index table is used to indicate the development degree corresponding to each environmental temperature within a unit time; according to the germination percentage and the development index table, the mouth opening prediction time and the germination prediction time of the target fish are obtained. The following technical effects are achieved: by establishing a regression equation group according to a time sample table, and obtaining a fry percentage and development index table according to the regression equation group, the problem of inaccurate estimation of fry emergence time and opening time, which easily causes fry death, is solved; by obtaining the predicted opening time and fry prediction time of target fish according to the fry percentage and development index table, the problem of low efficiency in estimating fry emergence time and opening time is solved; by introducing the development index to predict the development speed and time of fry emergence and opening at different temperatures, it is helpful to prepare for the transfer and cultivation of fry in advance, avoid unnecessary damage caused by fry backlog, improve the survival rate of fry cultivation, and promote the construction of sustainable artificial populations.
