Description

Technical Field

[0001] The present invention relates to the field of fish breeding, and particularly to a full-process breeding method and system for the Naozhou ethnic group large yellow croaker. Background Art

[0002] The Naozhou ethnic group large yellow croaker has fresh and delicious meat and is rich in nutrition. It is deeply favored by the market and has extremely high economic value. However, due to factors such as overfishing, habitat destruction, and marine environmental pollution, the wild resource volume of the Naozhou ethnic group large yellow croaker has decreased sharply and is on the verge of exhaustion. It has been listed as a national key protected aquatic wild animal. Therefore, carrying out the breeding research on the Naozhou ethnic group large yellow croaker is of great significance for restoring its population resources, meeting market demand, and protecting the marine ecosystem. At present, there is a certain research foundation on the breeding technology of large yellow croaker in China, mainly focusing on varieties such as the large yellow croaker in the East China Sea and the Minyue ethnic group large yellow croaker. Certain progress has been made in these researches in aspects such as broodstock cultivation, artificial induced spawning, fertilized egg hatching, and larval and juvenile fish cultivation, but there are still many technical bottlenecks, such as asynchronous gonadal development of broodstock, low fertilization rate, and low survival rate of larvae. In addition, there are significant differences in reproductive physiology, ecological habits, and environmental adaptability between the Naozhou ethnic group large yellow croaker and the large yellow croaker in the East China Sea. For example, the Naozhou ethnic group large yellow croaker has more demanding requirements for environmental factors such as water temperature and salinity, and its gonadal development cycle and spawning behavior also show unique seasonal patterns. Therefore, the existing breeding technology of the large yellow croaker in the East China Sea is difficult to be directly applied to the Naozhou ethnic group large yellow croaker, and it is urgent to optimize and innovate the technology according to its unique biological characteristics. In recent years, with the continuous progress of aquaculture technology, especially the application of technologies such as reproductive regulation, nutritional enhancement, and water quality regulation, new ideas have been provided for the breeding of the Naozhou ethnic group large yellow croaker. However, a full-process breeding technology system targeting its reproductive physiological characteristics has not been established, and related research is still in its infancy. Therefore, developing a full-process breeding method and system for the Naozhou ethnic group large yellow croaker not only helps to solve the problem of its resource exhaustion but also provides technical reference for the protection and sustainable utilization of other endangered economic fish.

[0032] Construct a breeding pond. If there are target parent fish that have spawned, transfer the target parent fish that have spawned to the breeding pond, where the water depth in the breeding pond is 2 m, the water salinity is 27.5‰, and the water temperature is 24.5°C;

[0050] Figure 3 Shows a program view of a full-process breeding system for Naozhou group large yellow croaker. Detailed implementation manners

[0051] In order to more clearly understand the above objects, features, and advantages of the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0052] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0053] Figure 1 Shows a flowchart of a full-process breeding method for Naozhou group large yellow croaker, including the following steps:

[0054] S102: Screen the Naozhou group large yellow croaker, determine the target broodstock, and control the stocking density of the target broodstock;

[0055] S104: Feed the target broodstock and perform inducing spawning treatment on the target broodstock;

[0056] S106: Check the eggs of the target broodstock after inducing spawning, and control the water quality parameters of the environment where the target broodstock is located during the egg-checking process.

[0057] Further, in a preferred embodiment of the present invention, the screening of the Naozhou group large yellow croaker, determining the target broodstock, and controlling the stocking density of the target broodstock are specifically as follows:

[0058] Obtain an indoor cement pond equipped with a heating device for breeding and culturing the Naozhou group large yellow croaker, and label it as the target breeding pond;

[0059] Among them, fill the water used for breeding the Naozhou ethnic group of large yellow croakers in the target breeding pond, and control the water depth to be 2 m, the water salinity to be 27.5‰, and the water temperature to be 24.5°C;

[0060] Obtain all the prepared and surviving Naozhou ethnic group of large yellow croakers, place the Naozhou ethnic group of large yellow croakers in the target breeding pond, and preset the broodstock screening time. After the Naozhou ethnic group of large yellow croakers are placed in the target breeding pond and pass the broodstock screening time, install an ultrasonic fish detector in the target breeding pond;

[0061] Based on the ultrasonic fish detector, emit ultrasonic fish detection signals to all the Naozhou ethnic group of large yellow croakers in the target breeding pond, and control the ultrasonic fish detector to receive and upload the reflected ultrasonic fish detection signals;

[0062] In the ultrasonic fish detector, determine the target broodstock by performing signal processing on the reflected ultrasonic fish detection signals;

[0063] Put the target broodstock in the target breeding pond, and control the release ratio of female broodstock to male broodstock to be 2:1, and control the release density of the target broodstock in the target breeding pond to be equal to 8 tails / m 3 water body;

[0064] Conduct a daily water exchange volume analysis on the target breeding pond. If the daily water exchange volume of the target breeding pond is not less than 400%, then control the release density of the target broodstock in the target breeding pond to be equal to 12 tails / m 3 water body.

[0065] It should be noted that in the breeding pond, the Naozhou ethnic group of large yellow croakers can be cultured and bred to achieve the purpose of ripening, and at the same time, the purpose is to obtain a large number of fry of the Naozhou ethnic group of large yellow croakers. Since the most suitable growth environment for the Naozhou ethnic group of large yellow croakers is a water depth of 2 m, a water salinity of 27.5‰, and a water temperature of 24.5°C, the water quality parameters of the water in the target breeding pond need to be adjusted to be equal to the above description. The ultrasonic fish detector is a device used to detect the appearance and body state of fish in water. After obtaining the target broodstock, the release density of the breeding broodstock is determined according to the water exchange volume, and the release density is 8 - 12 tails / m 3 water body, and the release ratio of female broodstock to male broodstock is 2:1, aiming to increase the spawning amount of the broodstock.

[0066] Furthermore, in a preferred embodiment of the present invention, the step of determining the target broodstock by performing signal processing on the reflected ultrasonic fish detection signals in the ultrasonic fish detector specifically includes:

[0067] Introduce a spatial domain filtering algorithm to perform spatial domain filtering on the reflected ultrasonic fish detection signals, and perform frequency domain processing on the spatially filtered ultrasonic fish detection signals;

[0068] Among them, the frequency-domain processing is to perform detail coefficient processing on the ultrasonic fish detection signal after spatial-domain filtering through a soft threshold function, improve the detail features of the ultrasonic fish detection signal after spatial-domain filtering, and obtain a preprocessed ultrasonic fish detection signal;

[0069] Introduce a delay superposition imaging algorithm to perform delay superposition imaging on the preprocessed ultrasonic fish detection signal, and perform frequency-domain reconstruction after delay superposition imaging to construct an ultrasonic fish detection image;

[0070] Perform logarithmic compression on the ultrasonic fish detection image, and map the logarithmically compressed ultrasonic fish detection image through the HSV color space to improve the brightness, hue, and contrast of the ultrasonic fish detection image. Finally, draw a three-dimensional image of the ultrasonic fish detection image to obtain a three-dimensional ultrasonic fish detection image;

[0071] Among them, different state information of the Naozhou ethnic group of large yellow croakers is obtained in the three-dimensional ultrasonic fish detection image. The state information of the Naozhou ethnic group of large yellow croakers includes the density of body surface scales, tail-swinging angle, gill cover opening and closing frequency, and mucus layer thickness of the Naozhou ethnic group of large yellow croakers;

[0072] Select Naozhou ethnic group of large yellow croakers with a body weight of 600 g, whose density of body surface scales, tail-swinging angle, gill cover opening and closing frequency, and mucus layer thickness are all maintained within the preset thresholds, and calibrate them as target parent fish.

[0073] It should be noted that the spatial-domain filtering algorithm is a beamforming algorithm, which is mainly used to adjust the collective dynamics of large yellow croakers and perform frequency-domain processing. Among them, the frequency-domain processing is to process the detail coefficients in the signal through the wavelet threshold denoising method to ensure that the noise data is removed when the signal is output, and improve the accuracy of the signal reflection. The purpose of the delay superposition imaging algorithm is to form image data from signal data, and the purpose of frequency-domain reconstruction is to reconstruct the frequency-domain data of the signal after noise reduction to restore the integrity of the data, so that the obtained image data can accurately reflect the state of fish. After obtaining the image, it is necessary to perform two-dimensional to three-dimensional modeling processing on the image. The three-dimensional image is easier to distinguish the state data of large yellow croakers, so as to achieve the purpose of screening target parent fish. Among them, logarithmic compression is to compress the dynamic range of pixels in the two-dimensional image data to realize the future of constructing a three-dimensional image, and perform HSV color space mapping, that is, map the color data in the pixels in the three-dimensional space, configure the color of the three-dimensional model, and finally obtain a three-dimensional ultrasonic fish detection image. It is necessary to select Naozhou ethnic group of large yellow croakers with a body weight of 300-600 g, which are physically strong, active, have strong stress resistance, and have no external injuries on the body surface, as parent fish. The state information of the Naozhou ethnic group of large yellow croakers includes the density of body surface scales, tail-swinging angle, gill cover opening and closing frequency, and mucus layer thickness of the Naozhou ethnic group of large yellow croakers. According to the above description, the target parent fish can be obtained.

[0074] Further, in a preferred embodiment of the present invention, the target broodstock after induced spawning is subjected to egg inspection, and the water quality parameters of the environment where the target broodstock is located are controlled during the egg inspection process. Specifically:

[0075] After inducing spawning in the target broodstock, a spawning pond and a hatching pond are constructed, and the target broodstock after induced spawning is placed in the spawning pond for egg inspection. Among them, the water depth in the spawning pond is 2m, the water salinity is 27.5‰, and the water temperature is 24.5°C;

[0076] Among them, the egg inspection process is as follows: a 150-mesh fishing net is set at the water outlet of the spawning pond. Every 4 hours, an image at the fishing net is obtained, and the image at the fishing net is filtered and feature extraction is performed to obtain the preprocessed image features of the fishing net;

[0077] Feature analysis is performed on the preprocessed image features of the fishing net to determine whether there are eggs of the Naozhou group of large yellow croakers at the fishing net. If so, the eggs of the Naozhou group of large yellow croakers are introduced into the hatching pond, and the egg inspection of the Naozhou group of large yellow croakers ends after 96 hours;

[0078] In the hatching pond, the water quality parameters of the water in the hatching pond are set to standard water quality parameters. Among them, the standard water quality parameters are: the hatching water temperature is 24.5°C, the water salinity is 27.5‰, the pH value is 7.8, and the dissolved oxygen in the water body is 4.00 - 6.00mg / L;

[0079] In the hatching pond, a water quality parameter sensor is placed, and the water quality parameters in the hatching pond are monitored in real time based on the water quality parameter sensor. If the water quality parameters in the hatching pond are not equal to the standard water quality parameters, a solution to adjust the water quality parameters to the standard water quality parameters is retrieved and output in the big data network.

[0080] It should be noted that 20 - 26 hours after artificial induced spawning, the male and female fish are placed in the spawning pond. A 100 - 150 - mesh fishing net is set at the water outlet of the spawning pond. Every 4 - 6 hours, check whether there are eggs in the net. If there are, collect them and gently pour them into the hatching pond for hatching, which continues until 72 - 96 hours after artificial induced spawning. The hatching water temperature is 20 - 24.5°C, the water salinity is 26 - 27.5‰, the pH value is between 7.6 - 7.8, and the dissolved oxygen in the water body is 4.00 - 6.00mg / L; In the initial stage after fry hatching, since their constitution is relatively fragile and extremely sensitive to environmental changes, special and meticulous care is required. To ensure the healthy growth of the fry, the primary task is to maintain sufficient dissolved oxygen in the water body. At the same time, frequent or violent water body disturbances should be avoided as much as possible to reduce the stress impact on the fry. In addition, maintaining stable water quality, appropriate temperature, and providing appropriate bait are also key measures to create a safe and stable growth environment for the fry.

[0081] Figure 2The method flow chart for inducing spawning of target broodstock is shown, including the following steps:

[0082] S202: Conduct bait feeding treatment on the target broodstock and conduct spawning induction treatment on the target broodstock;

[0083] S204: Conduct sexual maturity analysis on the target broodstock in the three-dimensional ultrasonic fish detection image after the intensive cultivation time, and conduct spawning induction treatment on the target broodstock based on the sexual maturity analysis result.

[0084] Furthermore, in a preferred embodiment of the present invention, the conducting bait feeding treatment on the target broodstock and conducting spawning induction treatment on the target broodstock are specifically as follows:

[0085] Obtain fresh frozen miscellaneous fish, and obtain a pulping device. Pour the fresh frozen miscellaneous fish into the pulping device for pulping treatment to obtain a fresh frozen miscellaneous fish pulp fluid;

[0086] Obtain eel powder, probiotics, multivitamins, fish oil, Huoli Jian, and minerals, and introduce the big data network. Retrieve all the mixing ratios of eel powder, probiotics, multivitamins, fish oil, Huoli Jian, minerals, and fresh frozen miscellaneous fish pulp fluid in the big data network, label them as the to-be-selected mixing ratios, and at the same time select the to-be-selected mixing ratio for bait feeding the Naozhou ethnic group large yellow croaker, and label it as the target mixing ratio;

[0087] Mix eel powder, probiotics, multivitamins, fish oil, Huoli Jian, minerals, and fresh frozen miscellaneous fish pulp fluid according to the target mixing ratio to make an intensified paste bait, label it as the target intensified bait, and at the same time retrieve the corresponding amount for 600 g of Naozhou ethnic group large yellow croaker in the big data network, and label it as the target bait amount;

[0088] Pour the target intensified bait into the target breeding pond, preset the intensive cultivation time, and ensure that the amount of the target intensified bait in the target breeding pond is equal to the target bait amount during the intensive cultivation time;

[0089] Conduct sexual maturity analysis on the target broodstock in the three-dimensional ultrasonic fish detection image after the intensive cultivation time, and conduct spawning induction treatment on the target broodstock based on the sexual maturity analysis result.

[0090] It should be noted that the present invention adopts a reinforced bait composed of a certain mass ratio of ice-fresh fish, eel powder, probiotics, multivitamins, fish oil, vitality and mineral premixes to strengthen the cultivation of the broodstock of the Naozhou tribe yellow croaker, and effectively ripens the broodstock by increasing the cultivation temperature, thereby increasing the proportion of sexually mature female or male broodstock, and at the same time increasing the number of eggs laid by female broodstock and the quality of fish eggs, thereby ensuring the large-scale acquisition of the fry of the Naozhou tribe yellow croaker, so it is necessary to mix ice-fresh fish, eel powder, probiotics, multivitamins, fish oil, vitality and minerals to obtain bait, and the yellow croaker is raised. The big data network can retrieve the mixing ratio of the substance, wherein ice-fresh fish: eel powder: soybean meal: wheat flour: fish oil: yeast: compound multivitamin: probiotics: vitality: mineral premix = 350:600:150:100:15:10:5:3:3:10.

[0091] Furthermore, in a preferred embodiment of the present invention, after the intensive cultivation time, the target broodstock are subjected to sexual maturity analysis in the ultrasonic fish detection three-dimensional image, and the target broodstock are subjected to induced spawning treatment based on the results of the sexual maturity analysis, specifically:

[0092] After the intensive cultivation time, different target broodstock are located in real time through ultrasonic fish detection three-dimensional images, and at the same time, whether the target broodstock have spawned is determined in the ultrasonic fish detection three-dimensional images;

[0093] Construct a breeding pond. If there are target broodstock for spawning, transfer the target broodstock for spawning to the breeding pond. The water in the breeding pond has a water depth of 2m, a water salinity of 27.5‰, and a water temperature of 24.5°C.

[0094] If there are no target broodstock for spawning, continue to carry out intensive cultivation of the target broodstock in the target breeding pond;

[0095] The spawning target broodstock are marked as sexually mature target broodstock, and ultrasonic fish detection three-dimensional images of all sexually mature target broodstock are obtained. Based on the ultrasonic fish detection three-dimensional images, two sexually mature target broodstock with the highest abdominal swelling rate and red genital opening are selected from all sexually mature target broodstock, wherein it is necessary to ensure that the selected sexually mature target broodstock include male fish and female fish;

[0096] The selected male fish were marked as sexually mature target male fish, and the selected female fish were marked as sexually mature target female fish. At the same time, LHRH-A2 was injected into the dorsal muscles of the sexually mature target male fish and the sexually mature target female fish. The injection dose for the control sexually mature target male fish was 1 μg / kg, and the injection dose for the sexually mature target male fish was 2 μg / kg.

[0097] It should be noted that after the intensive cultivation of large yellow croaker for a period of time, it is necessary to check the maturity of the target broodstock, and judge the maturity of the target broodstock by determining whether the target broodstock spawns. Among them, if the target broodstock spawns, it means that the target broodstock is mature. At this time, it is transferred to the culture pond for standby, aiming to select the target broodstock for induced spawning treatment. When sexually mature male broodstock are selected, female broodstock with a swollen abdomen, soft when touched, and a red genital pore can be selected for artificial induced spawning; while broodstock that are not sexually mature continue to be intensively cultivated. LHRH-A2 is an inducing agent that can catalyze the broodstock to carry out spawning treatment. According to the sexually mature target male fish and sexually mature target female fish obtained by screening, LHRH-A2 injection treatment is carried out on them to achieve the purpose of induced spawning. And the injection dose of the sexually mature target male fish is controlled at 1 μg / kg, and the injection dose of the sexually mature target female fish is 2 μg / kg.
