[0002] Traditional crucian carp farming methods often lack careful management of environmental factors, making it difficult to maximize the impact of the environment on crucian carp growth and reproduction. Improving production efficiency and yield has always been a focus of the aquaculture industry. Photoperiod, as a crucial biological factor, significantly influences fish growth, development, and reproduction.

[0003] In current crucian carp farming, photoperiod regulation is often based on experience and simple rules, lacking individuality and precision. The lack of systematic research and practical application of photoperiod regulation has led to potential waste of production efficiency and unnecessary increases in production costs.

By fully utilizing the photoperiod factors in the environment, the growth and reproduction process of crucian carp can be carefully managed to improve breeding efficiency, reduce costs, and increase production.

[0078] It should be noted that in the process of crucian carp reproduction research, since crucian carp has the ability to reproduce only in the adult stage, the growth stage of crucian carp is determined by the crucian carp image data in the crucian carp breeding site, and the adult fish group with reproductive ability is selected for analysis based on the identified growth stage. The adult fish group is monitored by monitoring the changes in reproductive hormone levels of crucian carp in different groups to understand the impact of the light cycle on reproductive hormones, so as to adjust the light cycle to promote or inhibit the reproduction of crucian carp; based on the impact data, targeted light control plans are formulated to improve the reproduction efficiency and yield of crucian carp, and by predicting the reproduction time of crucian carp, reasonable breeding plans are provided for farm owners; by comparing and evaluating the predicted crucian carp reproduction time with the actual reproduction cycle data, the actual effect of the light control plan can be understood, so that the light control plan can be adjusted and optimized in time to improve the breeding efficiency and economic benefits of crucian carp.

[0079] According to an embodiment of the present invention, the method of obtaining image data of crucian carp in a crucian carp breeding site and determining the growth stage of the crucian carp based on the image data of the crucian carp is specifically as follows:

[0080] Acquire crucian carp image data in a crucian carp breeding site by underwater camera equipment, and perform preprocessing operations on the crucian carp image data, wherein the preprocessing includes adjusting image size, enhancing contrast, and removing image noise;

[0081] Performing crucian carp region segmentation on the crucian carp image data after the pre-processing operation based on the OpenCV image processing library to obtain a crucian carp feature extraction area;

[0082] A threshold segmentation algorithm is introduced to convert the image of the crucian carp feature extraction area into a grayscale image, a segmentation threshold of the grayscale image foreground and background is determined according to the grayscale distribution of the grayscale image, and the grayscale image is threshold segmented according to the segmentation threshold to obtain a binary image;

[0084] The precise crucian carp feature extraction region is subjected to color space conversion by a color space conversion technology, a color histogram of the precise crucian carp feature extraction region is calculated, and color information of the crucian carp is determined according to the color histogram;

[0085] By calculating the gray level co-occurrence matrix of the precise crucian carp feature extraction area, determining the contrast and uniformity of the precise crucian carp feature extraction area according to the gray level co-occurrence matrix, the texture characteristics of the crucian carp are obtained;

[0086] Obtain appearance feature data of crucian carp at different growth stages, analyze the contour information, size characteristics, color information, and texture characteristics of the crucian carp based on the appearance feature data, and determine the growth stage of the crucian carp in the crucian carp breeding site.

[0087] It should be noted that, by identifying the growth stage of crucian carp through crucian carp image data in crucian carp breeding grounds, using OpenCV image processing library, threshold segmentation algorithm, color space conversion technology, grayscale co-occurrence matrix, and through multiple image processing technologies, real-time monitoring and automatic identification of crucian carp growth stage can be achieved, which improves management efficiency and accuracy, eliminates the tedious process of manual observation and judgment, and also reduces the possibility of human misjudgment; crucian carp image data is segmented into crucian carp areas through OpenCV image processing library to obtain a rectangular crucian carp area, which reduces the amount of data for image processing and improves the recognition speed of crucian carp, introduces threshold segmentation algorithm to extract crucian carp contour information, and performs secondary area selection based on the contour information to obtain accurate crucian carp feature extraction area, further improves recognition efficiency and reduces computer resource consumption; the foreground is crucian carp, and the background is image features other than crucian carp; the binary image is an image containing only black and white colors, wherein the white area represents the contour of the crucian carp.

[0088] According to an embodiment of the present invention, the fish schools are selected according to the growth stage of the crucian carp, the selected fish schools are divided into multiple groups, the fish schools in each group are cultured according to a preset light cycle, and the reproductive hormone level change data of the fish schools in each group are obtained, specifically:

A preset number of crucian carps in each group are obtained according to a preset time period for reproductive hormone measurement, and the reproductive hormone level change data of each group of fish groups are obtained.

[0102] It should be noted that by analyzing the effects of light on the reproductive hormones of crucian carp, we can better understand the mechanism of the influence of light on the reproductive hormones of crucian carp, which will help optimize the photoperiod regulation program to make it more suitable for the growth and reproduction needs of crucian carp; the multiple linear regression model can quantify the degree of influence of each independent variable on the dependent variable, that is, the regression coefficient of each factor. By analyzing the regression coefficient, we can determine the contribution of different factors to the changes in reproductive hormone levels, thereby more accurately evaluating the effects of light on the reproductive hormones of crucian carp.

[0120] Assessing the light attenuation of the lighting device based on the losses, determining whether the lighting device has reached a replacement condition based on the light attenuation, and replacing the lighting device if the replacement condition has been reached;

[0121] If the replacement condition is not met, a parameter compensation value of the lighting system is determined according to the light attenuation level, and a compensation operation is performed on the lighting parameters of the lighting system according to the parameter compensation value.

[0122] It should be noted that in the lighting system of the crucian carp breeding site, since the lighting equipment will cause light decay as the use time increases, the lighting data actually generated by the lighting equipment deviates from the parameters set by the lighting system and cannot reach the parameter values ​​set by the lighting system. Therefore, the degree of decline in the breeding efficiency of crucian carp is used to determine whether the lighting system has a light decay failure. Since the lighting equipment is expensive, the lighting equipment is processed by judging whether the replacement conditions are met. When the replacement conditions are met, the lighting equipment is replaced; if the replacement conditions are not met, the light decay degree of the lighting equipment is determined by comparing the parameters of the lighting system with the actual lighting data, and then the parameter compensation value of the lighting system is determined. The lighting system parameters are compensated according to the compensation value, so that the light emitted by the lighting equipment meets the light data in the lighting control plan; by considering the impact of the light decay of the lighting equipment on the reproduction of crucian carp, the impact of the lighting equipment problem on the reproduction efficiency of crucian carp is avoided.
