As a preferred embodiment, the step of controlling the temperature in the aquatic environment of the fish pond 5 comprises:

the detection probe 1 detects the temperature of the water in the fish pond 5, obtains the temperature data of the water in the fish pond 5 and sends the temperature data to the central processing unit 2;

The fancy carp is a temperature-variable animal, and the physiological characteristics ensure that the fancy carp does not have the capability of maintaining constant body temperature. If the temperature exceeds the range for a long time or a drastic temperature change occurs within the range, the koi will be in a stressed state. In general, this is relative. Roughly speaking, the influence of temperature change on koi is as follows: increased metabolic rate (10 ℃ increase in temperature doubles the rate of metabolism), disturbed respiration (warm water contains less oxygen than cold water), imbalanced pH in the blood and failure of osmotic regulation. The sudden temperature rise can cause problems of swim bladder and directly influence the growth and development of the fancy carp.

The adjusting ability of the koi under the high temperature condition is higher than that under the low temperature condition. The effect of temperature increase and decrease on koi is discussed below:

temperature rise:

firstly, spirulina in water is more vigorously metabolized, so that more oxygen is needed, the oxygen content in water is reduced (the content of oxygen dissolved in water is reduced by the increase of temperature), the high temperature changes the characteristics of protein and enzyme in the body, cells are damaged by harmful metabolites generated in the process, and the high temperature also causes the growth of inherent toxic substances, such as heavy metal or ammonia. At high temperatures, osmoregulation also occurs, since lipids change their morphology in the cell membrane, leading to an increase in the permeability of the cells, which is of crucial importance in gills. Under extreme warm environment, the fancy carp falls into a coma state because the central nervous system of the fancy carp is damaged. The highest temperature at which koi can survive is coordinated with the oxygen content and toxin levels in the water.

And (3) temperature reduction:

a reduction in temperature can also cause metabolic problems. At temperatures below 15c, metabolism is limited by temperature, and if koi cannot adapt to low temperatures, the release of energy will be reduced below the temperature at which it keeps its body functioning properly (above 15c, metabolism is also limited by the amount of oxygen contained in the water). Although the oxygen content of water at low temperatures is higher than that of water at higher temperatures, low temperatures also result in insufficient oxygen supply, which is referred to as "hypoxia". Oxygen uptake is limited by respiratory rate and heart rate. Sudden cooling can lead to the deterioration of red blood cells and the loss of oxygen-carrying hemoglobin, and can have a deleterious effect on respiratory efficiency. Low temperatures can lead to chronic regulatory penetration problems and aspiration of oxygen from the gills can be stopped, leading to renal failure. The cold pressure descending is usually manifested by motor imbalance and sudden spasm. Under the stimulation of extreme cold, the fancy carp also falls into a coma state due to central nerve paralysis. The opposite will occur if the environment changes to a good direction. Inappropriate temperatures and extreme temperature changes can reduce the function of the immune system.

As a preferred embodiment, the step of controlling the pH in the aquarium 5 water environment comprises:

the detection probe 1 detects the pH value of the water in the fishpond 5, acquires the pH value data of the water in the fishpond 5 and sends the pH value data to the central processor 2;

the data receiving module 21 of the central processing unit 2 receives the pH data sent by the detection probe 1 and sends the pH data to the data identifying module 22, the data identifying module 22 identifies the pH data and then correspondingly sends the pH data to the pH processing unit 232 of the data processing module 23 for comparative analysis, if the pH value is less than 7.0, a pH value increasing signal is generated to the acid-base adjusting device 32 of the executing device 3, and if the pH value is greater than 7.6, a pH value decreasing signal is generated to the acid-base adjusting device 32 of the executing device 3;

when the actuator 3 receives the pH value increasing signal, the acid-base adjusting device 32 adds the alkaline water-soluble substance, in this embodiment, sodium bicarbonate, to the fish pond 5, and if the actuator 3 receives the pH value decreasing signal, the acid-base adjusting device 32 adds the acidic water-soluble substance, in this embodiment, acetic acid, to the fish pond 5.

If the pH value exceeds the acid-base change range which can be adapted by the koi after being changed for a long time or the pH value changes sharply within the change range which can be borne by the koi in a short time, the koi can have the symptoms of acidosis or alkalosis.

Manifestation of acidosis

Although acidosis depends on the type of fish and the pH in the natural environment, acidosis usually occurs at a pH below 5.5. The behavioral responses of fish to acidosis are different due to different variation speeds, fish sensitivities and time periods. In the former case, the fish becomes very mobile, constantly swimming, shortness of breath, often jumping, and soon dying.

The acid not only irritates the gills, but also affects the skin and epidermis, resulting in excess mucus on the body surface (the skin is in the form of an emulsified mucus). The skin area turns red, especially in the abdomen, and too low a pH value also causes allergy to the fish, resulting in an increased probability of disease, especially bacterial infection.

Manifestation of alkalosis

Alkalosis is most likely to occur in environments with pH values greater than 8 or 9. Most acidophilic fish are subject to alkalosis at pH 8.

As a preferred embodiment, the fishpond 5 water environment is NH₃The concentration control step comprises the following steps:

the detection probe 1 carries out NH on the water in the fish pond 5₃Detecting the concentration to obtain NH of the water in the fishpond 5₃Concentration data, and NH₃The concentration data is sent to the central processing unit 2;

the data receiving module 21 of the central processing unit 2 receives the NH sent by the detection probe 1₃The concentration data is sent to the data identification module 22, and the data identification module 22 identifies NH₃After the concentration data are identified, the NH which is correspondingly sent to the data processing module 23₃The concentration processing unit 233 performs a comparative analysis process on NH₃At a concentration of > 0.015ppm, NH is formed₃NH of concentration-lowering signal to actuator 3₃The concentration adjusting device 33;

when the execution device 3 receives NH₃At the time of concentration decrease signal, NH₃The concentration adjusting device 33 adds nitrifying bacteria to the fish pond 5 or performs a sewage disposal treatment.

As a preferred embodiment, the fishpond 5 water environment is NH₄ ⁺The concentration control step comprises the following steps:

the detection probe 1 carries out NH on the water in the fish pond 5₄ ⁺Detecting the concentration to obtain NH of the water in the fishpond 5₄ ⁺Concentration data, and NH₄ ⁺The concentration data is sent to the central processing unit 2;

the data receiving module 21 of the central processing unit 2 receives the NH sent by the detection probe 1₄ ⁺The concentration data is sent to the data identification module 22, and the data identification module 22 identifies NH₄ ⁺After the concentration data are identified, the NH which is correspondingly sent to the data processing module 23₄ ⁺The concentration processing unit 234 performs a comparative analysis process if NH₄ ⁺At a concentration of > 0.5ppm, NH is formed₄ ⁺NH of concentration-lowering signal to actuator 3₄ ⁺In the concentration adjusting device 34;

when the execution device 3 receives NH₄ ⁺At the time of concentration decrease signal, NH₄ ⁺The concentration adjusting device 34 adds nitrifying bacteria to the fish pond 5 or performs sewage disposal.

The ammonia is generated in the process of obtaining energy through protein decomposition, and the ammonia is discharged through the branchia and simultaneously obtains sodium so as to ensure the balance of an ion system. The ammonia dissolved in water quickly generates ammonia ions (NH)₄ ⁺) And hydroxide ion (OH)^-). However, as the pH increases (i.e., water is biased toward basic) and temperature increases, these ions decompose into ammonia and water (NH)₃And H₂O) to form more free-form ammonia. Free form ammonia is more toxic than the ammonia ion. Therefore, at higher pH, it is important to control the ammonia content. For example, at a pH of 8, the free form of ammonia is only5%, and at a pH of 9, the content of free form ammonia is up to 20%.

The ammonia content is also particularly critical at high temperatures. The free form ammonia at 25 ℃ is 5 times the temperature at 5 ℃. The toxicity of ammonia decreases with increasing salinity in the water. For example, a 30% concentration of seawater is much less toxic than the same concentration of ammonia in fresh water.

Thus, the ammonia concentration in the water is clear from the known pH, temperature and salinity. Consider ammonia (NH)₄ ⁺) The absence of toxicity is entirely wrong.

The toxicity of free ammonia is high, the ammonia is a nitrogen-containing compound with the highest toxicity, the free ammonia has the lowest lethal toxicity to koi, namely 0.2-0.5 mg/L of free ammonia, which is a serious poisoning level, and the koi can be rapidly killed due to ammonia poisoning. Koi can be tolerated over a long period of time and does not show any chronic toxic reactions, e.g. the highest level of free ammonia increasing susceptibility to disease is 0.01-0.02 mg/L, where the following table is the total amount of ammonia recommended as a function of water temperature and pH:

ammonia acts as a series of harmful physiological effects that increase the total permeability of koi to affect the osmoregulation system, such as increasing the urine flow of koi, increasing the water drinking rate of koi, causing inflammation due to ammonia destruction of the mucus layer of gill, thus causing the respiration of koi to be affected, which also stimulates the gill to generate new cells on the surface, which is called neogenesis, hindering the water flow and thus reducing the uptake of oxygen. Ammonia also hinders the ability of hemoglobin to carry oxygen. Ammonia in lethal levels generally adversely affects koi, damaging the skin and mucous membranes of the intestine causing external bleeding and internal organ bleeding. Ammonia also damages the brain and central nervous system. At sub-lethal levels, ammonia is an intrinsic cause of certain diseases, including bacterial gill disease (the generation of proliferating cells makes gills more fragile, thereby causing bacterial invasion) and edema and fin rot.

As a preferred embodiment, the step of controlling turbidity in the water environment of the fish pond 5 comprises:

the detection probe 1 detects the turbidity of the water in the fishpond 5, obtains the turbidity data of the water in the fishpond 5 and sends the turbidity data to the central processing unit 2;

the data receiving module 21 of the central processing unit 2 receives the turbidity data sent by the detection probe 1 and sends the turbidity data to the data identification module 22, the data identification module 22 identifies the turbidity data and then correspondingly sends the turbidity data to the turbidity processing unit 235 of the data processing module 23 for comparative analysis, and if the turbidity is greater than 10NTU, a turbidity reducing signal is generated and sent to the turbidity adjusting device 35 of the execution device 3;

when the execution device 3 receives the turbidity reduction signal, the sterilizing lamp in the turbidity adjusting device 35 is turned on, and the circulating water filtering function of the fishpond 5 is increased.

As a preferred embodiment, the step of controlling the oxygen capacity of the aquatic environment in the fish pond 5 comprises:

the detection probe 1 detects the oxygen capacity of the water in the fish pond 5, obtains the oxygen capacity data of the water in the fish pond 5 and sends the oxygen capacity data to the central processing unit 2;

the data receiving module 21 of the central processing unit 2 receives the oxygen volume data sent by the detection probe 1 and sends the oxygen volume data to the data recognition module 22, the data recognition module 22 recognizes the oxygen volume data and then correspondingly sends the oxygen volume data to the oxygen volume processing unit 236 of the data processing module 23 for comparative analysis, if the oxygen volume is less than 6mg/L, an oxygen volume increasing signal is generated to the oxygen volume adjusting device 36 of the execution device 3, and if the oxygen volume is greater than 10mg/L, an oxygen volume decreasing signal is generated to the oxygen volume adjusting device 36 of the execution device 3;

when the execution device 3 receives a signal that the oxygen capacity in the fish pond 5 is lower than the normal range value, the oxygen pump in the oxygen capacity regulating device 36 is turned on or liquid oxygen is added into the fish pond 5, and when the execution device 3 receives a signal that the oxygen capacity in the fish pond 5 is higher than the normal range value, the deaerator in the oxygen capacity regulating device 36 is turned on.

The gases that can be dissolved mainly in water are: carbon dioxide, oxygen, and nitrogen. The relative mass of these gases in water can reflect different solubilities. Carbon dioxide is the most readily soluble gas and oxygen is much easier than nitrogen. The ratio of the solubilities of carbon dioxide, oxygen and nitrogen in water was 70:2: 1.

The oxygen solubility in water is 20-30 times less than that of air, and the oxygen solubility decreases with the increase of temperature and increases with the increase of salt. The more organic matter in the water, the more decomposed matter is in the bacterial activity and is in the process of decomposition.

When the oxygen concentration in water is lower than the most announced oxygen content in the koi body, the growth, reproduction and physiological functions of the koi body are influenced, and the koi body is susceptible to diseases (the influence of the low oxygen content on the reproduction, including the inhibition of the development of roes, the malformation of small fish and the high death rate of fry) is inevitably caused. When the oxygen content is continuously reduced to a certain degree and still the koi can keep breathing, the 'tissue hypoxia' state can occur. In this case, the koi will breathe on the surface of the water. The koi reduces the beating times of the heart, increases the beating amplitude of the heart, consumes less energy and ensures the normal blood circulation, and the koi adapts to lower oxygen content in the mode. In this process, the ventilation is also increased, for example koi breathes 70 times per minute in water containing 11mg of oxygen per liter, and 140 breaths per minute in water containing 3mg of oxygen. If the oxygen content of the environment continues to decrease to a lethal minimum, the respiration and oxygen uptake rates will decrease accordingly, since the compensatory mechanisms are destroyed in this state and large amounts of carbon dioxide can have a deleterious effect. At this time koi will make an evasive response in an attempt to seek a high water-soluble oxygen content. If this attempt is unsuccessful, koi will go into coma, lose self-balance, roll the belly and then die from oxygen deficiency, e.g. complete oxygen deficiency will cause denudation of gill surface protection and failure of gill function.

Despite the large gas exchange surface, the fish ponds 5 in gardens still encounter problems in maintaining oxygen content, even if you are operating according to the growth laws of plants and fancy carps. In summer, algae grows vigorously, oxygen in water is excessively saturated through photosynthesis in the day, and the oxygen is consumed at night, so that the fancy carp dies in the morning. Prevention of algal overgrowth is a key solution, so it should be avoided to construct the fish pond 5 in a place where there is no direct sunlight, and to plant some plants that compete with algae for light and nutrients. Mounting ultraviolet UV is an effective method.

As a preferred embodiment, the step of controlling the nitrite concentration in the aquatic environment of the fish pond 5 comprises:

the detection probe 1 detects the nitrite concentration of the water in the fish pond 5 to obtain the nitrite concentration data of the water in the fish pond 5 and sends the nitrite concentration data to the central processing unit 2;

the data receiving module 21 of the central processing unit 2 receives the nitrite concentration data sent by the detection probe 1 and sends the nitrite concentration data to the data identification module 22, the data identification module 22 identifies the nitrite concentration data and then correspondingly sends the nitrite concentration data to the nitrite concentration processing unit 237 of the data processing module 23 for comparison analysis processing, if the nitrite concentration is greater than 0, a nitrite concentration eliminating signal is generated and sent to the nitrite concentration adjusting device 37 of the execution device 3;

when the execution means 3 receives the nitrite concentration elimination signal, the nitrite concentration adjustment means 37 adds a weakly alkaline neutralizing agent, in this example sodium bicarbonate, to the fish pond 5, or performs a water change sewage disposal process.

In the presence of oxygen, the bacteria containing the nitrites convert ammonia to nitrites, which is one of the steps in the nitrification process. Nitrite is toxic because it can destroy red blood cells, oxidise the iron in hemoglobin into a stable compound called methemoglobin, which has no oxygen carrying capacity (this process turns gill and blood brown), so that koi living in a fish pond environment with nitrite can make koi in a sub-healthy state for a long time, which affects the growth of koi, and even endangers the life of koi when the nitrite concentration in the fish pond reaches a certain value.

The symptoms of nitrite poisoning cause anemic and hypoxic processes in the organism (i.e., oxygen levels below the minimum level required for sustained respiration) and pigmentation of organs such as the liver, spleen and kidney (usually in the form of black spots). The toxicity of nitrite can be reduced by increasing the content of the dissolved salt, so that the toxicity of nitrite in seawater is low, and the toxicity of nitrite in hard water is also reduced. For example, the same level of toxicity was detected in hard water of 18mg/L nitrite and soft water of 10 mg. This inference is not fully confirmed, but in any case, increasing the concentration to 0.01% (0.1 mg/L salt, i.e., sodium chloride) reduces the high nitrite content in fresh water.

As a preferred embodiment, the step of controlling the nitrate concentration in the aquatic environment of the fish pond 5 comprises:

the detection probe 1 detects the nitrate concentration of the water in the fish pond 5 to obtain the nitrate concentration data of the water in the fish pond 5 and sends the nitrate concentration data to the central processor 2;

the data receiving module 21 of the central processing unit 2 receives the nitrate concentration data sent by the detection probe 1 and sends the nitrate concentration data to the data recognition module 22, the data recognition module 22 recognizes the nitrate concentration data and then correspondingly sends the data to the nitrate concentration processing unit 238 of the data processing module 23 for comparative analysis, and if the nitrate concentration is greater than 5ppm, a nitrate concentration reduction signal is generated and sent to the nitrate concentration adjusting device 38 of the execution device 3;

when the execution means 3 receives the nitrate concentration decrease signal, the nitrate concentration adjustment means 38 adds the weakly alkaline neutralizing agent to the fish pond 5.

Nitrifying bacteria oxidize nitrite to less toxic nitrate, a process called nitrification. In 50-300 mg/L water, nitrate contains the lowest concentration toxicity, and the water area is suitable for the survival of extremely sensitive fancy carps. For instance in koi, nitrate is 200 times less toxic than nitrite, but in water, fish eggs and fish fries are more sensitive to nitrite than adult fish. The toxicity of nitrate in salt water is higher than in fresh water, and because the content of nitrate in the ocean is almost zero, we can reasonably speculate that high concentration of nitrate in the ocean can enhance the susceptibility and spread rate of diseases.

In a closed aquarium or aquarium 5 environment, ammonia lost in the form of ammonia can accumulate and reach toxic levels if not dealt with in any way. One of the main functions of biofiltration is therefore to reduce the ammonia content to a less toxic substance. Although the manner of biological filtration is varied, the principle of filtration is the same. Biofiltration provides the best conditions for the nitration process. Through this process certain bacteria gradually decompose ammonia. Nitrite is produced in the first stage and then becomes nitrate in the second stage. All filters contain a medium with as large a surface area as possible to ensure the colonization of nitrifying bacteria. These bacteria require a constant supply of nutrients and sufficient oxygen provided by the ammonia-containing compounds to effect the nitrification process. These conditions are provided by the circulating oxygenated water containing rich ammonia waste through the filter. This nitration process also depends on the pH and temperature conditions.

The control method of the content of ammonia, nitrite and nitrate comprises the following steps:

the most ideal environment is that the pH value is 7.5, the corresponding maximum temperature is 30 ℃ in fresh water and 30-35 ℃ in seawater, and the temperature is usually too high for the koi. The ammonia, nitrite and nitrate levels can be readily detected using simple test tools. Ideally, the total ammonia and nitrite content is maintained below 0.1mg/L and the nitrate content is maintained below 20 mg/L. An effective filtration cycle should maintain the ammonia and nitrite levels well below this limit, and if the concentrations are above this limit, a number of problems can arise, the most likely explanation being that the filters are not fully installed, a condition known as "new tank syndrome". At 25 ℃, the biofilter takes approximately 2-6 weeks to culture the complement of nitrifying bacteria. The ripening process takes 4-8 weeks at 10 ℃. We can speed up this process by a number of methods, for example bacteria in dry or liquid form can be cultured on the filter, or some media can be added using a healthy water tank.

The control method of the nitrate comprises the following steps:

the use of chemical filter media can more effectively absorb excess ammonia, such as zeolites (naturally occurring) or artificial adsorbents. And depending on the severity of the problem, water can be replaced by up to 75%. (zeolites cannot be used in seawater, artificial adsorbents) care should be taken at the same time to ensure that the pH does not rise suddenly after the water change. It is known that at high pH, a large amount of free ammonia is present, which increases the risk to koi. For the case of elevated nitrite, a partial water change of up to 50% can be used, after which the effect of nitrite is reduced by adding 0.01% strength brine (sodium bicarbonate). At these times, the causes of these conditions are discovered as soon as possible and measures are taken for the specific conditions.

Daily careful management enables to control the increase in nitrate content: changing water over a two week period dilutes and reduces the nitrate content. Nitrate can also be removed by actively growing plants because they must absorb nitrate as they grow. There are also some filtration devices that remove nitrate that can create low oxygen conditions, i.e., conditions where the oxygen content is less than 1 mg/L. Under these conditions, the anaerobes will be contaminated with nitrate ions (NO)₃ ^-) The oxygen is absorbed, and finally only the ammonia gas left is discharged from the water as waste. These low oxygen environments can be achieved by reducing the circulating water flow, installing anaerobic tanks, or using microporous filter media. Deammoniation requires charcoal to provide food for the bacteria, which requires a media structure or a liquid or solid "food".

Preparation of second, brocade carp before stocking

1. Cement alkali removal

The newly built cement pond is harmful to the health of koi because cement alkali can seep out of concrete, and therefore, the cement alkali must be removed before the koi enters the pond. The cement alkali can be removed by an acetic acid method, a dry ice method, a plastic coating method, or the like. Generally, an acid neutralization method is used, namely after a newly built pond is filled with water, about 50g of glacial acetic acid is added into each cubic meter of water and is uniformly mixed, the mixture is soaked for 24-48 hours, the water is discharged and repeated, then the cement pond is soaked by clear water for about one week, and the mixture is drained for use.

2. Water quality requirement

In order to make the color of the koi bright and glossy, the water quality must be adjusted to an ideal state. The ideal water quality requires the pH value to be 7.1-7.3, the contents of iron ions, chloride ions, sulfate ions and the like are low, the dissolved oxygen is sufficient, and the hardness is below 8 German degrees. Groundwater is often rich in heavy metal ions and has low dissolved oxygen and must be treated for use. Tap water is treated water, the source is convenient, but residual chlorine in the water is harmful to the fancy carps, and the chlorine is removed through aeration and then added into the fishpond 5. Rainwater has a low pH and contains many undesirable factors, and thus attempts are made to avoid mixing it with pond water. Regardless of the water used, it is not advisable to add too much fresh water for a short time, or the fish may cause illness due to maladaptation.

Third, matching of breeding species

The fancy carp is bred in the courtyard, and an observer can appreciate the style of the fancy carp from any angle. According to the visual effect, one or more of red and white koi, major positive three-color koi and showa koi are usually used as main materials, and other bright-colored species such as golden koi, white koi, light yellow koi, white writing koi, and autumn koi are usually matched.

Fourth, feeding management

Management of five or more seasons

Season changes, climatic conditions are greatly different, particularly in northern areas, four seasons are clear, and the feeding management of the fancy carps is also different.

1. Spring: the temperature is unstable, and when the temperature is greatly reduced, a plastic film is covered on the fish pond 5 to ensure the stable water temperature. When the feed is fed, the animal feed and the plant feed are matched, and the feed cannot be fed with single and indigestible high protein or high fat feed. The spring is the season of bacterial growth, and the disinfection of the culture pond should be paid attention.

2. Summer: the temperature is high, the water temperature is also high, and a sunshade net is covered on the fish pond 5 to prevent the water temperature from rising; meanwhile, summer is also the season of mass propagation and growth of aquatic phytoplankton, and an ultraviolet germicidal lamp is preferably arranged in the culture pond to keep good water quality.

3. In autumn: the autumn is high and comfortable, the season is the best season for the growth of the koi, and more feed needs to be fed at the moment so that the koi can store physical strength and safely overwinter.

4. In winter: in cold weather, the temperature and the water temperature can also fall, sometimes the temperature is close to the freezing point, and the fancy carp can safely overwinter outdoors. At the moment, the fancy carp does not need to be fed, and a small ice hole is preferably chiseled on the breeding pond to increase dissolved oxygen in water.

Sixth, daily management

1. The most important thing for raising the fancy carp is that the water quality management is carried out, the excrement and the residual feed of the fish body are removed in time, the bottom water of a pool or the bottom water of a filter tank needs to be discharged 1-2 times every day, and meanwhile, the filter tank needs to be washed by a reverse washing method commonly, and the excrement, the residual feed, suspended impurities, heavy metal ions and other harmful factors of the fancy carp are discharged.

2. When the water flow is not smooth or the filtration circulation is poor, a layer of sludge is often accumulated at the corners of the pool and is sucked out by a siphon method frequently to keep the water in the pool clean.

3. The upper water discharge pipe is often blocked by larger impurities, so that the upper water cannot be smoothly discharged, and therefore, the upper water discharge pipe needs to be frequently observed and timely removed.

4. The leaves falling into the cement pond can not only cause the water in the pond to rot, but also consume dissolved oxygen, and must be removed in time.

The above description is only a preferred embodiment of the present invention, and the technical solutions that achieve the objects of the present invention by substantially the same means are within the protection scope of the present invention.
