Description

[0001] Eel nursery device for growing growth rate and survival rate using magnetized water [

The present invention relates to a freshwater eel aquaculture system, and more particularly, to a system and a method for controlling a freshwater eel aquaculture system, which is based on ICT (Information and Communications Technologies) Data can be transmitted and received to monitor the situation both inside and outside of the farm in real time from the remote location. Integrated management is possible from leptose sepharose, fresh eel, and sea eel, and growth rate and survival rate can be greatly improved. It is possible to contribute to the promotion of the income of the farm farmers by contributing to national economic development by increasing the export of freshwater eels through mass production by suggesting a model that can systematize freshwater eel culture and integrate management of large scale aquaculture. The present invention relates to a freshwater eel aquaculture apparatus.

According to the general classification of fishes, there are two types of fishes: spawning / hatching and growing in freshwater, fishes that spawn / hatch and grow in seawater, and migratory fishes that flow in and out of freshwater and seawater for breeding. Among them, It is divided into salty fish such as salmon or wild boar, and seahorse fish that grow in seawater and freshwater eel such as freshwater eel or steep eel.

Such migratory fishes, including migratory fishes and submerged fishes, must maintain equilibrium in the body fluids in the body and in the salinity of the surrounding water that migrate from freshwater to seawater or from seawater to freshwater.

In other words, migratory fishes are controlled so that the osmotic pressure in the body is kept constant when they move from fresh water to seawater or from seawater to fresh water. The freshwater fish (i.e., freshwater fish) Therefore, the water is infused into the body through the skin and the gill to infiltrate into the body through the osmotic pressure, and the body fluid is diluted. Therefore, the water must be continuously discharged while the water of the sea water is higher than the body fluid of the sea water. And it is subjected to a process of adaptation and regulation in the brackishwater zone (or estuary) in order to control the salinity concentration by such osmotic pressure.

Especially, the ecological migration characteristics of representative freshwater eels are as follows: Leptocephalus (Leptocephalus; ie freshwater eel) in the deep sea of the Pacific (estimated as the western part of the Mariana Islands in the South Pacific) And then travels northward along the northern ocean current and then along the Kuroshio Current to the north direction and reaches the coast and becomes secondary to the eel.

The eels are gathered in the waters (eg estuaries) to regulate the concentration of saline by the osmotic process and then move to rivers, rivers or reservoirs for a certain period of time and then stay for a certain period in the watershed for scattering, After the adjustment process of concentration, it goes back to the deep sea region of the Pacific Ocean again.

Therefore, in consideration of the ecological characteristics of the sea eel which is transformed from freshwater eel fish (ie, Leptosepalus) in the seawater, Eels are preferred if they are equipped with aquaculture system in which the conditions of sea water, nose and fresh water are provided in the aquaculture process to grow from the stage to the adult stage.

This type of system is designed in such a way that the seawater, the wastewater and the freshwater station are mixed with the circulating filtration system of the aquaculture water and the fresh water system so as to comply with the phasing of the freshwater eel disclosed in Korean Patent No. 10-1587860, This is presented in the water tank device for freshwater eel culture that is adapted to the culture from the stage to the stage of the eel.

On the other hand, freshwater eels are often susceptible to changes in water quality, so they are often killed in the course of cultivation. In the case of purification and circulation of aquaculture water, water quality management becomes more important. In Korean Patent No. 10-1609905 A purification method for treating estrogen-containing wastewater, which is simply a mature hormone, is disclosed.

In order to increase the growth rate of freshwater eel aquaculture and to increase the survival rate, it is necessary to accurately grasp the degree of water pollution due to feed, feeding period, and feed input. However, such conditions are not stored in an experimental database It is true.

Taken together, the survival rate of young eels and fry is low at 5% when cultivating freshwater eels. To increase this survival rate, an integrated management system that optimizes various parameters in a comprehensive manner is needed. However, until now, research on the construction of the integrated management system required for freshwater eel culture has been lacking, and there has been no bold investment in research due to the fact that freshwater eels are cultivated in a medium and small scale compared to a large market scale.

Korean Patent No. 10-1587860 Korean Patent No. 10-1609905 Korean Patent No. 10-1587855 Korean Patent No. 10-1587850 Korean Patent No. 10-1587853 Korean Patent Publication No. 10-2014-0137508

Fig. 2 is a block diagram showing various apparatuses for water tank management of the invention.

1 and 2, the freshwater eel aquaculture apparatus according to the present invention includes a water tank 110 containing water for aquaculture and having a freshwater eel (eel, A water quality measuring instrument 127 for displaying and transmitting the water quality data measured by the sensor 120 and the image transmitted from the camera 125 and the water quality data received from the water quality measuring instrument 127; Image data received from the gateway 130 and photo / image data received from the camera, and transmits the received water quality data, photo / image data, and analysis data to the gateway 130 And a user terminal 137 for receiving the water quality data, the photo / image data, and the analysis data from the integrated management server 135.

On the other hand, the power source of the farm 100 is constructed of a bottle thermal type, a constant power source, an emergency power source, and an emergency standby power source, and automatically supplies emergency power source in an emergency.

A control room 101 is provided on one side of the aquaculture facility 100 and the integrated management server 135 for managing and sending the received data is installed to manage the quality of water in real time in and out of the aquaculture facility.

As shown in FIG. 2, the water tank 110 of the present invention includes a water tank 111 for watering freshwater eel fish, a water tank 112 for fish breeding freshwater eel fish and a water tank 112 for raising fresh water eel And a baby-use water tank 113.

It is preferable to prepare a large amount of water tanks instead of a small water tank size in comparison with the child-friendly water tank 113 so that they are cultured at a low density.

It is preferable not to administer the antibiotics used in the eel or the freshwater fish eel culture in the production of the eel or the fish. In order to control the growth and the water quality of freshwater eel, harmless growth hormone or algae plankton microorganism (probiotic bacteria) is used As a result, it is possible to manage environmentally friendly water quality because it is cultivated with non-antibiotic feed.

The sensor 120 and the camera 125 are installed in the self-supporting water tank 111, the juvenile water tank 112 and the biological water tank 113 to measure water quality data, You can observe eels.

The sensor 120 may include at least one of a dissolved oxygen amount measuring sensor 121, a pH measuring sensor 122, a water temperature measuring sensor 123, a nitrate measuring sensor, an ammonia measuring sensor, and a salinity measuring sensor , But this is only an example, so a sensor not mentioned above may be added as long as it can measure water quality data.

The sensor 120 can transmit water quality data by wire or wirelessly.

The dissolved oxygen amount measuring sensor 121 may measure the dissolved oxygen amount of the aquaculture water in a polar graphic manner.

The pH measuring sensor 122 may illustrate measuring the pH of aquaculture water in a composite glass electrode manner.

The water temperature measuring sensor 123 may measure the water temperature of the aquaculture water by the RTD method.

The water quality meter 127 receives and displays water quality data from the sensor 120 through wired or wireless communication and transmits the received water quality data to the gateway 130.

The gateway 130 can wirelessly communicate with the water quality measuring instrument 127 and the integrated management server 135 in the LTE / 3G system as well as near-distance communication within about 1 km.

The integrated management server 135 receives the water quality data from the gateway 130, receives the photo / image data from the camera 125, and transmits the water quality data and the photo / image data to the user terminal 137.

In addition to the camera 125, the inside of the water tank can be precisely monitored through a microscope to more accurately observe the rearing condition of freshwater eels.

In addition, microscopic infrared cameras can be installed to check the micro temperature of the ears or fry to check whether the disease is present or not prior to the onset of the disease or the population. The growth and changes of the ears or the fry are checked periodically for growth rate Improvement in survival rate, and management of feed and water tank are preferable.

The integrated management server 135 calculates the water quality analysis data by comparing the received water quality data with preset reference values.

For example, if the water temperature measured by the water temperature sensor 123 is 30 ° C and the preset reference value is 28 ° C, analysis data indicating that the water temperature is higher than a preset reference temperature can be transmitted to the user terminal.

This analysis data is calculated for each water quality data measured by each sensor (for example, water temperature, pH, dissolved oxygen amount, etc.) in comparison with each reference value.

On the other hand, among the freshwater eels, the cause of the diseases such as the fry or the ear is mainly caused by the cleaning state of the water tank, poor quality of feed, feed overload, high density breeding, bad chewing, deteriorating water quality, bacterial disease caused by wound, By thoroughly and integrally controlling and controlling all of the causes based on the measured data, it is possible to increase the growth rate and control quality.

Furthermore, before the freshwater eels are stored in a tank, a program to discriminate the defective fish is operated, and thorough management of the water quality is carried out to zero the infection of the disease. If the disease occurs in one of the tanks, And it is possible to take measures such as detection of defective larvae with a special infrared camera in real time, so that it can prevent the transmission to other freshwater eels in advance. In other words, database of the optimal body temperature of freshwater eels with the best temperature and immunity of the freshwater eels is automatically databaseed and stored in a tank.

The user terminal 137 receives and displays the water quality data, the photograph / image data, and the analysis data from the integrated management server 135, and may be a smart phone, a PC, or the like. In this manner, the user terminal 137 can receive the water quality data from a remote location in real time, and can visually check the situation in the water tank 110 through photographs / images, thereby facilitating water quality management and reducing labor costs can do.

In the present invention, not only monitoring the water quality of the aquaculture water in the water tank and sending warning messages but also sending out the aquaculture water control device 150, the aquaculture water circulation and purification device 160, Feed feeder 180 and / or light adjuster 119. The feeder device 180 may be any of the following:

Each of the above devices can be operated through the integrated management server 135 or the user terminal 137.

For example, the integrated management server 135 can automatically manage the water quality by operating the devices 150, 160, 170, and 180. When the water quality data measured by the sensor 120 is out of a preset reference value, 150, 160, 170, and 180) to automatically control each device.

In this case, the administrator can view the water quality data, the photo / image data, and the analysis data received through the user terminal 137, and transmit the user data to the user terminal 137 It is possible to control each of the devices by transmitting a control command through the controller. In this case, the control commands transmitted from the user terminal 137 can be directly transmitted to the respective devices 150, 160, 170 and 180 or transmitted to the respective devices 150, 160, 170 and 180 through the integrated management server 135, Since the management history is stored in the database 135, the management history can be used as a database.

4 is a block diagram showing the configuration of a water control system according to the present invention.

4, the water control apparatus 150 may include a seawater supply tank 151 and a fresh water supply tank 152, a heater and a cooler 153, and a pH control tank 154 .

The seawater supply tank 151 and the fresh water supply tank 152 may maintain the aquaculture water in the water tank 110 either as seawater, nose water or fresh water, lower the salinity in seawater or nose water, And serves to supply seawater and fresh water to the water tank.

Generally, freshwater eels are grown in freshwater, nose, and sea water due to ecological migration characteristics.

For example, in order to produce artificial seeds from freshwater eels caught in freshwater, sexual maturity is induced by hormone therapy, so that ovulation and fertilization are performed for a certain period of time in the nadir so as to adapt to seawater. .

Specifically, freshwater eels, sea water, and sea water are switched between freshwater eels that have been scattered in seawater or are managed for artificial hatching. To this end, seawater supply tanks and fresh water supply tanks are connected to the fish tank or fish tank .

For example, in the case of the fish tank 113, fresh water is initially supplied to the sea water supply tank 151, and a predetermined amount of seawater is introduced from the sea water supply tank 151 to the sea water. Then, . At this time, when the integrated management server 135 sends a control command to the seawater supply tank 151 to supply a predetermined amount of seawater to the fish tank 113, The electronic control valve provided in the pipe connecting the water tank 113 opens the pipe according to the control command to supply the seawater.

In the salinity sensor installed in the fish tank 113, the salinity according to the inflow of seawater is measured and transmitted in real time, and the integrated management server 135 controls the amount of seawater supply and the period based on the measured salinity.

The heater and the cooler 153 are installed in the water tub 110 to control the temperature of the water. The intensity of on-off, heating, and cooling is controlled by the integrated management server 135.

The pH control tank 154 may be connected to the water tank 110, the seawater supply tank 151, the fresh water supply tank 152 or the aquaculture water circulation and purification apparatus 160 through piping or the like, And serves to supply a pH adjusting agent.

That is, in the present invention, the water in the water tank is filtered using the water-based filtration method, and the water quality is managed through a multi-stage filtration process. The water, water temperature, pH, DO, salinity, sterilization, Because it is managed separately, even if a water quality problem occurs in one tank, it can be managed independently from other tank, so the risk of collective mortality can be reduced.

Once a week, the larvae of each of the aquariums can be stored and managed in the integrated management server by observing the growth state of the fishes such as the spawning fishes and the frying fishes through a galena microscope observation.

2 and 3, the aquaculture water circulation and purification apparatus 160 purifies the overflowed water in each water tank 110 and supplies the purified water to the water tank 110 for circulation.

For example, the aquarium circulation and purification apparatus 160 installed in the biological water tank includes an outlet 117 provided at one side of the upper part of the water tank 110, a tubular guide member 161 communicating with the outlet 117, A drainage passage 173 starting from a lower portion of the lower end of the guide member 161 and an aeration tank 165 for receiving the aquaculture water supplied from the drainage passage 173 and aeration oxygen to control the dissolved oxygen ratio of the aquaculture water A sterilization tank 166 for sterilizing the aquaculture water that has passed through the aeration tank 165; a degassing tank 168 for degassing carbon dioxide from the aqua regime that has passed through the sterilization tank 166; And a biofilter filtration tank 167 of a split loop type for biophotically filtering the passed form number.

The sterilization tank 166 includes a first sterilization tank 166a in which an ultraviolet lamp is installed, a second sterilization tank 166b in which an ultraviolet filter is installed, a third sterilization tank 166c ).

The biofilter filtration tank 167 serves to decompose ammonia and the like through the biofilter.

However, the sterilization and purification means mentioned above are merely illustrative, and it goes without saying that various known sterilization and purification means can be added.
FIG. 5A is a block diagram showing the construction of the magnetized water producing apparatus of the present invention, FIG. 5B is a perspective view showing a state in which an ultraviolet irradiating device is provided in a drainage path and a photocatalytic decomposition section of the present invention, And a magnetized water generating unit.

delete

5A to 6, in the present invention, a magnetized water generating apparatus 170 may be installed together with a water circulation and purification apparatus.

The magnetized water generating device 170 may be disposed before and after the aeration tank 165, the sterilizing tank 166, and the biofilter filtration tank 167.

More specifically, the magnetized water generating device 170 includes a primary magnetized water generating portion 171 formed at the bottom of the drainage passage 173 at a predetermined interval and composed of a plurality of first magnet members 174, A magnetizing water tank 178 for receiving the aqua regenerated water through the generator 171, a rotary shaft 179 inserted in the magnetized water tank 178, a second magnet member 179a provided on the rotary shaft 179, And a secondary magnetized water generating unit 177 including the magnetized water generating unit 177.

The primary magnetized water generating section 171 preliminarily supplies a magnetic force for magnetized water generation and then the secondary magnetized water generating section 177 magnetizes the culture water. When the number of forms is magnetized It has the advantage of improving the survival rate or growth by improving the biological activity of freshwater eel.

On the other hand, the aquaculture water that is overflowed in each water tank can be merged and aeration, sterilized, and filtered in the drainage channel 173.

For example, since a plurality of water tanks have the same water temperature and the same water quality conditions such as salinity and pH, they can be cleaned by merging the discharged aquaculture water, and then the purified water can be distributed. However, when the conditions of water quality such as water temperature, salinity, and sex hormone input are different, the drainage channel should be separated by water quality condition and treated separately.

Specifically, it is preferable to treat the juvenile fish tank 113 into which the mature hormone is injected into the aquaculture water through the separate drainage line 173 without joining with the aquaculture water of the other aquarium.

For example, in the case where 17β-estradiol or the like is added to the aquaculture water discharged from the water tank, at least a part of the drainage passage 173 through which the water containing the mature hormone is discharged contains photocatalyst powder on its surface The photocatalytic decomposition section 175 is formed.

The photocatalytic decomposition section 175 may be provided with an ultraviolet irradiation device 176.

As shown in the drawing, the drainage passage 173 may have a completely opened upper part or a closed pipe shape.

Fig. 7 is a schematic view showing the feed feeding apparatus of the present invention. Fig.

Referring to FIG. 7, the feed feeder 180 supplies feeds in liquid or powder form, and the amount and type of feed are automatically controlled in accordance with the type of freshwater eels raised in each water tank, Nitrate, and viral infections caused by corruption in the real-time monitoring can be prevented in advance.

The feed feeder 180 is mainly composed of an air jetting section 181, one end connected to the air jetting section 181 and the other end inserted into the water in the water tray 110, And a feed supply tank 184 communicating with one side of the air injection pipe 182.

The feed tank 184 may be provided with an electronic control valve 183 disposed above the air injection pipe 182 and controlling feeding of the feed.

The air spraying unit 181 communicates with the air spraying pipe 182 and supplies air of a predetermined pressure to provide an impelling force for feeding the feed supplied from the feed supply tank 184.

The air supplied from the air jetting section 181 is aerated in the aquaculture water to feed the feed.

In the case of feeding the feed with the air jet method, since the aeration is intermittently performed when the feed is supplied to the water tank, the water quality can be improved. Especially when the upper part of the water tank is opened, effective.

FIG. 8 is a schematic view showing the baby-use water tank of the present invention. FIG.

Referring to FIG. 8, the light control device 119 is installed in a closed water tank to periodically irradiate light.

In the case of a water tank having a closed upper part, for example, a water tank 113 for a fish tank, it is possible to minimize the influence of external temperature, external illumination, and the like. However, it is needless to say that ventilation holes or ventilation fans 113a, which are ventilatable, may be provided on the upper side to allow ventilation.

In the meantime, the biological water tank 113 of the present invention has a tapered cross section that becomes narrower as the bottom part 114 goes downward, and a sediment discharge pipe 115 can be connected to the lowermost end.

A mesh member 116 through which the sediment can pass is installed in the lateral direction of the bottom part 114 so that the freshwater eel in the water tank does not flow into the lower part of the mesh member 116. When the net member 116 is installed as described above, the sediment can be intensively received in the lower portion of the net member, and the sediment can be selectively discharged through the sediment discharging pipe 115 regularly.

A water supply pipe 118 or an air spray pipe 182 for supplying water for culture water is connected to the upper portion of the net member 116 and an outlet 117 for discharging water for culture and suspended matters is formed in the upper part of the water supply pipe . Since the water supply port is disposed above the mesh member 116, it is possible to prevent floatation of the sediment as much as possible, and exchange of the purified water and the aquaculture water in the water tank can be performed more smoothly.

2, the freshwater eel aquaculture apparatus may be installed in an integrated management module including an upper stage 103 and a lower stage 104 provided below the upper stage 103.

The upper stage 103 is divided into at least the plurality of reservoir water tanks 111, the piercing water tank 112 and the piercing water tank 113. The number of ponds discharged from the piercing water tank 113 is Is purified separately from the aquaculture water discharged from the other water tanks 111 and 112.

The aquaculture water discharged from each water tank is re-supplied to the corresponding aquarium through piping and a pump (not shown) through the aquaculture water circulating and purifying device 160 provided in the lower stage 114.

Feed is automatically supplied to each of the spring water tank 111, the fish water tank 112, and the fish water tank 113 through a separate feed water feeding device 180.

In the control room 101 provided at one side of the lower stage 103, at least one of a water quality meter, a gateway and an integrated management server is installed, and all situations inside and outside the water tank are integrally managed through the received data.

On the other hand, in the case of a large number of reservoir water tanks 111, there is a difference in the growth period of the inner fish in each water tank, a difference in the number of weights (density), and an average weight / size of each weigher. Can be controlled differently, and the individualized control can be performed such as the increase and decrease of the purification treatment cycle and the water quality management step. In other words, although a large number of water tanks of the same kind are gathered together, this is for convenience of management, so it provides an optimized environment for the characteristics of each individual, and has an advantage of increasing the growth rate through individual water quality management and feeding management.

In addition, the integrated management server is an optimized freshwater eel style model that can enhance the growth rate and survival rate by collecting data on water quality, feed quantity, feeding cycle, and growth data, and then using the AI program to evaluate the accumulated data. Modify, and supplement.

In this way, when the farm facility is integrated management modularized, various kinds of water tanks are installed in one place, specifically, in the upper stage, so that management is easy and highly concentrated farms can be designed.
