[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Figure 1 A flow chart of a method provided by an embodiment of the present invention, such as Figure 1 As shown, the present invention provides a method for estimating respiration in a waterless environment during a fish keeping alive process, comprising:

[0046] Step 100: Obtain the weight of the individual fish to be tested, the volume of the fish body, the volume of the sealed packaging bag, and the initial amount of oxygen in the sealed packaging bag, and collect the timing parameters associated with breathing in a waterless environment with a preset sampling period and a preset sampling step length during the survival process of the individual fish in the preset temperature zone:

[0049] Step 400: Calculate the respiration rate of the fish per unit time according to the oxygen consumption rate and carbon dioxide release rate in each time period in the preset temperature zone and preset cycle.

[0050] Figure 2 is a flow chart of a multi-stage evaluation method for the storage and transportation of raw aquatic products provided by an embodiment of the present invention, such as Figure 2 As shown, including:

[0051] S1, obtain the weight W and volume V of the fish to be tested W , Volume of sealed packaging bag V PThe initial oxygen volume B0 in the sealed packaging bag and the breathing-related timing parameters of the fish individuals collected in the preset temperature zone Tem in the waterless environment with the same preset sampling period ΔT and the same preset sampling step length t: temperature a i 、Oxygen b i 、CO2 i , gill amplitude d i Timing parameters of

[0052] Specifically, the fish individuals to be tested are sea bass and salmon, and the preset temperature zones are set to 5 temperature zones: the first temperature zone [0-1.5℃], the second temperature zone [1-2.5℃], the third temperature zone [1.5-3℃], the fourth temperature zone [2-3.5℃], and the fifth temperature zone [2.5-4℃]. The respiratory-related timing parameters with the same preset sampling period ΔT and the same preset sampling step t (t<ΔT) in the 5 temperature zones are obtained respectively: the timing parameters of temperature, oxygen, carbon dioxide, and fish gill amplitude.

[0053] S2, dividing the preset sampling period ΔT into N time periods;

[0054] Specifically, the standard reference values ​​of temperature, oxygen, carbon dioxide, and gill amplitude parameters within the preset sampling period ΔT are obtained and processed by the following formula:

[0055]

[0056] Where X represents the standard reference value of the parameter within the preset sampling period ΔT, X i (max) represents the maximum value of the parameter within the preset sampling period ΔT, X i (min) represents the minimum value of the parameter within the preset sampling period ΔT, and n represents the number of data;

[0057] Obtain the fluctuation deviation of temperature, oxygen, carbon dioxide, and gill amplitude parameters within the preset sampling period ΔT and process them using the following formula:

[0058]

[0059] Among them, γ∈[0,1] is the fluctuation deviation value of each parameter within the preset sampling period ΔT, X i is the sampling value within the preset sampling period ΔT, and X is the standard reference value within the preset sampling period ΔT.

[0060] The deviation limit is used as the time period division point to divide the time period into N time periods.

[0061] In the actual process of fish transportation without water, γ>0.5 is specifically set as the deviation limit for time period division.

[0062] S3, calculate the correlation coefficient r of temperature, oxygen, carbon dioxide, and gill amplitude parameters in each period under the preset temperature zone i , specifically including:

[0063] The correlation analysis between the time series parameters of each divided period is carried out. i ∈[-1,1], and compare the correlation coefficients of each time period based on historical experience knowledge. For example, oxygen and carbon dioxide are negatively correlated, and oxygen and respiratory amplitude are positively correlated. If the correlation coefficients between the parameters of a certain time period are opposite, the data needs to be verified and abnormal judgment processed, and the correlation judgment is performed between the processing until they are consistent.

[0064] The consistency of the correlation coefficients in each period can indicate the consistency of the data and provide reliability for the estimation of respiratory rate.

[0065] S4, calculating the change rate coefficient of two adjacent divided time periods in the preset temperature zone is specifically:

[0066]

[0067] in, A represents the average value of the parameter in the Δt period, i (Δt)max represents the maximum value of the parameter within the Δt period. is the average value within the period Δt+1.

[0068] It should be pointed out that δ i ∈[0,1), during the waterless live transport process, the rate of change of the parameters at each time period reflects the respiratory state of the fish, δ i The greater the rate of change, the greater the impact on the respiratory state of fish.

[0069] It is necessary to further explain that the oxygen consumption of fish is greatly affected by temperature, oxygen and carbon dioxide parameters. The delta values ​​of each parameter are set according to the preset knowledge base. i (First temperature zone)≤δ i (Second temperature zone)≤δ i (Third temperature zone)≤δ i (Fourth temperature zone)≤δ i (Fifth temperature zone).

[0070] S4: Calculate the oxygen consumption rate OCR (O2) and carbon dioxide release rate OCR (CO2) in the anhydrous environment during the fish individual survival process in each period of the preset temperature zone and preset period ΔT. The specific calculation is:

[0071] OCR(O2)=[k·(V P -V W )·W N ] / (G(Ba -B i ))×100%

[0072] OCR(CO2)=[k·(V P -V W )·W N ] / (G(C a -C i ))×100%

[0073] Among them, k is related to the individual difference characteristics of fish, K∈(0,1],V P V is the volume of the sealed packaging bag during the process of keeping fish alive without water. W is the fish body volume, W N is the fish body weight at each time period, G(B a ), G(B i ) are the initial and final oxygen concentrations of fish in each period, assuming that in the first period G(B a )=B0,G(C a ), G(C i ) are the starting and ending concentrations of carbon dioxide for fish in each time period.

[0074] It should be noted that it is assumed that the changes in fish weight and volume during the waterless transportation of fish are very small, that is, there is no change treatment.

[0075] In addition, the respiration rates of different fish species are not only affected by the environment, but also related to their own individual differences. For example, the suitable temperature zone for sea bass is different from that for salmon. The oxygen consumption of salmon obtained based on the knowledge base has a greater impact, so the k value of salmon is larger than that of sea bass.

[0076] S5: Calculate the oxygen consumption rate OCR (O2) and carbon dioxide release rate OCR (CO2) in each period of the preset temperature zone and preset period ΔT, and calculate the respiratory rate of the fish individual in each period by the following formula:

[0077] BR=(θ·(OCR(O2))+(1-θ)·(OCR(CO2)))·ε ci

[0078] Among them, θ represents the weight coefficient, which is comprehensively determined based on the change rate coefficient of temperature, oxygen, carbon dioxide and gill amplitude. When OCR(O2)>OCR(CO2), θ>(1-θ), otherwise θ<(1-θ).

[0079] ε ci is the coefficient of change of gill amplitude δ ci The relevant correction coefficient of ci is not 0, then εci The value is 1, if δ ci is 0, then ε ci The value is 0.

[0080] The embodiment of the present invention estimates the respiratory rate of individual fish in a waterless environment, which helps to optimize the respiratory-related parameters of the waterless environment and improve the survival rate of fish during waterless transportation.
