Description

Technical Field

[0001] The invention relates to the field of fish breeding, and in particular to a mandarin fish breeding and domestication management system and method based on factory circulating water. Background Art

[0002] As the global population grows and consumers' demand for high-quality aquatic products increases, traditional fisheries face multiple challenges such as resource depletion, environmental pollution and low aquaculture efficiency. In order to meet these challenges, factory recirculating aquaculture technology has emerged, which achieves efficient, environmentally friendly and sustainable aquaculture by recycling water resources in a closed system and combining advanced aquaculture management and biotechnology.

[0003] As a freshwater fish with high economic value and delicious taste, mandarin fish has a large market demand, but its natural reproduction rate is low and it has high requirements for the breeding environment. Traditional pond breeding not only occupies a large area and consumes a lot of water resources, but is also easily affected by the external environment, such as temperature, water quality, and disease, resulting in low breeding efficiency and unstable product quality. Summary of the invention

[0004] The purpose of the present invention is to provide a system and method for the domestication and management of mandarin fish culture based on industrial circulating water to solve the above technical problems.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A circulating water treatment module is used to realize the circulation and purification of aquaculture water; it includes at least one aquaculture pond and one or more water purification devices;

[0008] Environmental control module: including temperature control equipment and oxygenation equipment, used to adjust the water temperature in the breeding pond and increase the dissolved oxygen content in the water to maintain environmental conditions suitable for the growth of mandarin fish;

[0009] Automatic feeding module: including an automatic feeding machine, which feeds the corresponding feed according to the growth stage, feeding habits and health status of the mandarin fish, and realizes the smooth transition of the mandarin fish from natural feeding habits to artificial feed by gradually adjusting the feeding method and feed type;

[0010] Intelligent monitoring and management module: used to monitor the aquaculture environment parameters and the growth status parameters of mandarin fish in real time, analyze the monitoring data, and provide corresponding aquaculture adjustment strategies based on the analysis results.

[0011] As a further technical solution, the breeding environment parameters include water temperature, dissolved oxygen content and water quality indicators, and the growth status parameters include body weight, body length parameters and activity status.

[0012] As a further technical solution, the process of analyzing the monitoring data is as follows:

[0013] The water temperature W collected in the i-th breeding pond i , dissolved oxygen content O i And the water quality assessment index P is substituted into the formula:

[0014]

[0015] Calculate the breeding environment index A i ; Among them, O i0 is the standard dissolved oxygen content, ΔO th is the reference deviation value of dissolved oxygen;

[0016] The body weight G collected in the i-th breeding pond ij , body length L ij Substituting into the formula:

[0017]

[0018] Calculate the growth status index B i ; Where N is the number of sampled fish in the ith breeding pond, G ij is the weight of the jth fish, L ij is the body length of the jth fish, K ij is the activity coefficient of the jth fish, and ΔR is the reference value.

[0019] As a further technical solution, the calculated breeding environment index A i and growth status index B i Compare them with their corresponding warning values ​​respectively:

[0020] If the breeding environment index A i , Growth status index B i Both exceeded their respective warning values ​​A i0 , B i0 , then it is judged that the circulating water treatment module and the environmental control module are operating normally;

[0021] If A i i0 or B i i0 , then the calculated breeding environment index A i and growth status index B i Substituting into the formula:

[0022]

[0023] Calculate the breeding trend coefficient δ i ​​; Then the calculated breeding trend coefficient δ i Compared with the preset breeding trend interval [δ ia , δ ib ] to make comparisons and conduct further analysis based on the comparison results;

[0024] Among them, t0 and t1 are the time endpoints on both sides of the statistical period, A i (t) is the curve of the change of aquaculture environment index over time during the statistical period, B i (t) is the curve of growth status index changing with time during the statistical period;

[0025] If A i i0 And B i i0 , it is judged that both the circulating water treatment module and the environmental control module have failure risks.

[0026] As a further technical solution, the breeding trend coefficient δ i Compared with the preset breeding trend interval [δ ia , δ ib The comparison process is:

[0027] If δ i ∈[δ ia , δ ib ], it is judged that the current breeding pond is in a stable state;

[0028] If δ i ∈[δ ib , +∞], it is judged that the current breeding pond is in a deteriorating state;

[0029] If δ i ∈[-∞,δ ia ], it is judged that the current breeding pond is in a good trend.

[0030] As a further technical solution, the process of further analysis based on the comparison results is:

[0031] The aquaculture ponds judged to be in a state of deterioration shall be marked as key ones, and the aquaculture ponds judged to be in a state of stability shall be marked as ordinary ones;

[0032] Obtain the number of highlighted aquaculture pools. If the number of highlighted aquaculture pools is greater than 1 / 3 of the total number of aquaculture pools, it is determined that the circulating water treatment module has a fault risk.

[0033] If the number of key-marked aquaculture pools is less than 1 / 3 of the total number of aquaculture pools, the number of key-marked aquaculture pools mh and the number of ordinary-marked aquaculture pools mp are obtained by the formula: The breeding assessment change value Fs is calculated; ​​

[0034] Compare the aquaculture evaluation change value Fs with the aquaculture evaluation change threshold F0. If Fs ≥ F0, it is determined that there is a risk of failure in the circulating water treatment module; if Fs < F0, it is determined that there is a risk of failure in the environmental control module;

[0035] wherein, mh max 、mh min are respectively the maximum number and the minimum number of the aquaculture ponds marked as key in one cycle, mp max 、mp min are respectively the maximum number and the minimum number of the aquaculture ponds marked as ordinary in one cycle, and ω1, ω2 are preset weight coefficients.

[0036] As a further technical solution, the process of providing a corresponding aquaculture adjustment strategy according to the analysis result is as follows:

[0037] If it is determined that there are risks of failure in both the circulating water treatment module and the environmental control module, start the emergency response program to conduct synchronous fault troubleshooting and maintenance on the circulating water treatment module and the environmental control module;

[0038] If there is a risk of failure in the circulating water treatment module, check and maintain the water purification device, and take corresponding repair measures according to the cause of the failure;

[0039] If there is a risk of failure in the environmental control module, adjust the growth environment in each aquaculture pond according to the priority order of key marking > ordinary marking > no marking.

[0046] 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.

[0047] See also Figure 1 As shown, the present invention is a mandarin fish breeding and domestication management system based on industrial circulating water, comprising:

[0048] A circulating water treatment module is used to realize the circulation and purification of aquaculture water; it includes at least one aquaculture pond, one or more water purification devices, such as filters, bioreactors, and ultraviolet disinfectors, while maintaining appropriate water quality parameters, such as pH value, dissolved oxygen content, ammonia nitrogen and nitrite concentrations;

[0049] Example:

[0050] There are 4 independent breeding ponds, each with a capacity of 50 cubic meters. The circular design is used to optimize the water flow distribution. There is a sewage outlet at the bottom of the breeding pond to facilitate regular cleaning of sediments. The water purification device includes:

[0051] Filter: Physical filtration is used to remove suspended particles in the water using a sand filter with a pore size of 5 microns;

[0052] Bioreactor: Install aerobic bioreactors to use microorganisms to decompose organic matter and reduce ammonia nitrogen and nitrite content;

[0053] Ultraviolet disinfection device: Install ultraviolet disinfection device at the outlet of each breeding pond to kill pathogenic microorganisms in the water and ensure water quality safety;

[0054] Water quality parameter control:

[0055] The pH value was maintained between 6.5 and 7.5 by adding acid-base regulators.

[0056] The dissolved oxygen content is maintained above 5 mg / L by oxygenation equipment such as air pumps and aeration plates.

[0057] The concentrations of ammonia nitrogen and nitrite are controlled below 0.5 mg / L and 0.1 mg / L respectively through the action of the bioreactor.

[0058] Environmental control module: including temperature control equipment and oxygenation equipment, used to adjust the water temperature in the breeding pond and increase the dissolved oxygen content in the water to maintain environmental conditions suitable for the growth of mandarin fish; for example:

[0059] Temperature control equipment: Install heating rods and cooling systems above each breeding pond to automatically adjust the water temperature according to seasonal changes and keep it within the optimal growth range of 20-28℃;

[0060] Oxygenation equipment: Each culture pond is equipped with two air pumps, which are connected to the aeration plate at the bottom of the pond through pipes to ensure uniform distribution and sufficient supply of dissolved oxygen in the water;

[0061] Automatic feeding module: including automatic feeding machine, feeding corresponding feed according to the growth stage, feeding habits and health status of mandarin fish, and gradually adjusting the feeding method and feed type to achieve a smooth transition from natural feeding habits to artificial feed for mandarin fish; programmable feeding machine can be used to set feeding time and feeding amount according to the growth stage of mandarin fish; live bait such as small fry is used for domestication in the early stage, and gradually transition to high-protein artificial feed;

[0062] Intelligent monitoring and management module: used to monitor the aquaculture environment parameters and the growth status parameters of mandarin fish in real time. The aquaculture environment parameters include water temperature, dissolved oxygen content and water quality indicators, and the growth status parameters include weight, body length parameters and activity status; by analyzing the monitoring data, and then providing corresponding aquaculture adjustment strategies according to the analysis results;

[0063] For example: installing temperature sensors, dissolved oxygen sensors, pH sensors and water quality analyzers in the breeding pond to monitor water quality and environmental parameters in real time; growth status monitoring: using underwater cameras and automatic weighing systems to regularly record the weight, body length and activity of mandarin fish.

[0064] In this embodiment, the recycling and efficient purification of aquaculture water bodies are realized through the circulating water treatment module, which reduces water resource consumption and environmental pollution. At the same time, the environmental control module ensures that the mandarin fish is always in the best growth environment, and improves the growth rate and survival rate; the automatic feeding module can accurately feed the mandarin fish according to the growth stage and health status of the mandarin fish, reducing feed waste, improving feed conversion rate, and smoothly carrying out the domestication process, and also reducing dependence on live bait and reducing breeding costs; the intelligent monitoring and management module realizes real-time monitoring and data analysis of the breeding environment, providing a scientific decision-making basis for breeders, and improving the accuracy and efficiency of breeding management. At the same time, predicting the growth status of mandarin fish through data analysis helps to prevent diseases and respond to emergencies in advance, reduces breeding risks, and is environmentally friendly and sustainable. It protects the ecological environment through measures such as recycling water resources and reducing the use of chemicals.

[0065] The process of analyzing monitoring data is as follows:

[0066] The water temperature W collected in the i-th breeding pond i , dissolved oxygen content O i And the water quality assessment index P is substituted into the formula:

[0067]

[0068] Calculate the breeding environment index A i ; Among them, O i0 is the standard dissolved oxygen content, ΔO th is the reference deviation value of dissolved oxygen;

[0069] The process of obtaining the water quality assessment index P is as follows:

[0070] The collected water quality parameters: pH value, dissolved oxygen content, ammonia nitrogen and nitrite concentration are input into the pre-trained recurrent neural network model, and the water quality evaluation index P is output; the larger the water quality evaluation index, the better the water quality;

[0071] The body weight G collected in the i-th breeding pond ij , body length L ij Substituting into the formula:

[0072]

[0073] Calculate the growth status index B i ; Where N is the number of sampled fish in the ith breeding pond, G ij is the weight of the jth fish, L ij is the body length of the jth fish, K ij is the activity coefficient of the jth fish, that is, K ij is the swimming distance of each fish per hour, and ΔR is the reference value.

[0074] In this embodiment, a method for analyzing monitoring data is provided. Specifically, first, the water temperature W collected in the i-th breeding pond is i , dissolved oxygen content O i And the water quality assessment index P is substituted into the formula: Calculate the breeding environment index A i ; Obviously, if |W i -W ith The smaller the value, the smaller the temperature deviation is, so the water temperature in the breeding pond is more suitable. The larger the value, the greater the value. i -O i0 The smaller the value, the smaller the deviation of dissolved oxygen content, so the oxygen content in the breeding pond is more reasonable. Similarly, the larger the water quality assessment index is, the more reasonable the water quality in the breeding pond is.

[0075] Then the body weight G collected in the i-th breeding pond ij , body length L ij Substituting into the formula: Calculate the growth status index B i ; Obviously, The larger the value is, the better the growth of the sampled fish is; the larger the weight and body length are, the faster the sampled fish grows; and the larger the activity coefficient is, the better the activity of the sampled fish is, which means the higher the probability that the sampled fish is healthy.

[0076] The calculated breeding environment index A i and growth status index B i Compare them with their corresponding warning values ​​respectively:

[0077] If the breeding environment index A i , Growth status index B i Both exceeded their respective warning values ​​A i0 , B i0 , then it is judged that the circulating water treatment module and the environmental control module are operating normally;

[0078] If A i i0 or B i i0 , then the calculated breeding environment index A i and growth status index B i Substituting into the formula:

[0079]

[0080] Calculate the breeding trend coefficient δ i ​​; Then the calculated breeding trend coefficient δ i Compared with the preset breeding trend interval [δ ia , δ ib ] to make comparisons and conduct further analysis based on the comparison results;

[0081] Among them, t0 and t1 are the time endpoints on both sides of the statistical period, A i (t) is the curve of the change of aquaculture environment index over time during the statistical period, B i (t) is the growth status index change curve over time during the statistical period; the breeding trend coefficient δ i Compared with the preset breeding trend interval [δ ia , δ ib ]The comparison process is: if δ i ∈[δ ia , δ ib ], then the current breeding pond is judged to be in a stable state; if δ i ∈[δ ib , +∞], then the current aquaculture pond is judged to be in a deteriorating state; if δ i ∈[-∞,δ ia ], it is judged that the current breeding pond is in a good trend;

[0082] If A i i0 And B i i0 , it is judged that both the circulating water treatment module and the environmental control module have failure risks.

[0083] In this embodiment, it is provided how to judge whether there is a problem in breeding and which module may have a risk of failure; specifically, firstly, the calculated breeding environment index A i and growth status index B i Compare them with their corresponding warning values ​​respectively. If A i i0 And B i i0 , it means that there are problems with both water quality and environmental parameters, so there is a risk of failure in both the circulating water treatment module and the environmental control module. The situation is more urgent at this time because there are risks in multiple breeding ponds involved; if A i i0 or B i i0 , it is judged that there is a water quality problem or an environmental parameter problem, but in order to reduce the error of real-time measurement, Calculate the breeding trend coefficient δ i , to reflect the cumulative changes in the breeding environment indicators and growth status indicators within a statistical period. Obviously, A i0 -A​​​​​​i (t) The larger it is, the greater the deviation of the actual aquaculture environment index from the warning value, so the higher the probability that there are problems with the aquaculture water quality, B i0 -B i (t) The larger it is, the greater the deviation of the actual growth state index from the warning value, so the higher the probability that there are problems with the aquaculture environment; based on the above formula, the trend state of the current aquaculture pond can be predicted. Obviously, δ i ∈[δ ia ,δ ib , it is determined that the current aquaculture pond is in a stable state. If δ i ∈[δ ib ,+∞], it is determined that the current aquaculture pond is in a deteriorating state. If δ i ∈[-∞, δ ia , it is determined that the current aquaculture pond is in a improving state, thus providing strong data support for subsequent strategy adjustment.

[0084] The process of further analysis based on the comparison results is as follows:

[0085] Mark the aquaculture ponds judged to be in a deteriorating state as key, and mark the aquaculture ponds judged to be in a stable state as ordinary;

[0086] Obtain the number of aquaculture ponds marked as key. If the number of aquaculture ponds marked as key is greater than 1 / 3 of the total number of aquaculture ponds, it is judged that there is a risk of failure in the circulating water treatment module;

[0087] If the number of aquaculture ponds marked as key is less than 1 / 3 of the total number of aquaculture ponds, obtain the number mh of aquaculture ponds marked as key and the number mp of aquaculture ponds marked as ordinary. Through the formula: Calculate the aquaculture evaluation change value Fs;

[0088] Compare the aquaculture evaluation change value Fs with the aquaculture evaluation change threshold F0. If Fs≥F0, it is judged that there is a risk of failure in the circulating water treatment module; if Fs<F0, it is judged that there is a risk of failure in the environmental control module;

[0089] Among them, mh max 、mh min are respectively the maximum number and minimum number of aquaculture ponds marked as key in a cycle, mp max 、mp min are respectively the maximum number and minimum number of aquaculture ponds marked as ordinary in a cycle, and ω1, ω2 are preset weight coefficients.

[0090] The process of providing corresponding aquaculture adjustment strategies according to the analysis results is as follows:

[0091] If it is determined that both the circulating water treatment module and the environmental control module have a risk of failure, the corresponding emergency procedure is initiated to perform synchronous troubleshooting and maintenance on the circulating water treatment module and the environmental control module;

[0092] If there is a risk of failure in the circulating water treatment module, the water purification device should be inspected and maintained, and appropriate repair measures should be taken according to the cause of the failure;

[0093] If there is a risk of failure in the environmental control module, the growth environment in each breeding pond will be adjusted in the priority order of key mark > ordinary mark > no mark.

[0094] In this embodiment, if the analysis results of the intelligent monitoring and management module show that both the circulating water treatment module and the environmental control module have a risk of failure, the emergency response program should be immediately initiated to perform synchronous troubleshooting and maintenance work on these two modules. Since these two modules are directly related to the quality of the aquaculture water body and the stability of the growth environment, their normal operation is crucial;

[0095] If only the circulating water treatment module is at risk of failure, a professional team should be immediately organized to inspect and maintain water purification devices such as filters, bioreactors, and ultraviolet disinfectors; at the same time, appropriate repair measures should be taken according to the specific cause of the failure to ensure that water quality parameters such as pH value, dissolved oxygen content, ammonia nitrogen and nitrite concentrations can be quickly restored to an appropriate range;

[0096] If only the environmental control module has a risk of failure, the growth environment should be adjusted in priority order according to the growth stage and health status of the mandarin fish in the breeding pond and the actual conditions of the breeding environment; specifically:

[0097] Key mark breeding ponds: For breeding ponds with abnormal growth environment parameters that have a greater impact on the growth of mandarin fish, priority should be given to environmental regulation, such as adjusting water temperature and increasing dissolved oxygen, to ensure the normal growth of mandarin fish;

[0098] Ordinary marked breeding ponds: For breeding ponds where the growth environment parameters are basically normal but there are potential risks, appropriate environmental adjustments should be made to prevent potential problems from occurring;

[0099] Unmarked breeding ponds: For breeding ponds with stable growth environment parameters and no negative impact on the growth of mandarin fish, the current environmental status can be maintained, but its changing trend still needs to be closely monitored;

[0100] While making the above adjustments, the intelligent monitoring and management module should continuously monitor the parameters of the breeding environment and the growth status of the mandarin fish, and adjust the breeding strategy in a timely manner according to the monitoring results. If the fault risk is eliminated or the breeding environment is improved, the normal breeding state can be gradually restored; if the fault risk persists or the breeding environment deteriorates further, further response measures should be taken immediately.

[0101] A method for the domestication and management of mandarin fish culture based on industrial circulating water, the method is implemented based on the mandarin fish culture domestication and management system based on industrial circulating water.

[0102] It should be noted that the calculation formulas and various parameters involved in the calculations in the present invention have been dimensionally processed in advance, and the process of dimensionless processing is well known in the industry and will not be described here.

[0103] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
