Description

FISH CULTIVATING SYSTEM USING SOUND WAVE AND METHOD THEREOF}

The present invention relates to a cage farming system and method, and more particularly, to a cage farming system and method for forming a cage region by a sonic wall made of sound waves avoided by fish.

Cage farming means netting a certain area of the sea and breeding fish in it. In general, the fish farms are surrounded by 5 nets except the water surface, so that fish can be trapped. The nets need to be maintained and repaired regularly, and the size of the nets is limited, making it difficult to secure a large space. There are disadvantages of this, and a new concept of cage farm is needed to solve this.

Sound means that the vibration of molecules spreads in the form of waves, and the frequency of the wavelength determines the height of the sound, and the size of the wavelength determines the intensity of the sound. The speed of sound waves in the water is 1,500 m / s, and it is about 4 times faster than the speed of sound waves in the air, 340 m / s, and the intensity of sound attenuation with distance is small, so sound transmission in water is relatively far. Can be.

Fish do not have an externally protruding ear, but sound can be recognized by the inner ear located inside the head bone and the lateral line located on both sides of the torso. The inner ear of fish can be recognized directly, and the lateral line can sense vibration and water flow. In particular, the audible frequency range of fish is known to be from about 16 Hz to 13000 Hz, and the recognizable frequency band may be different depending on the fish species.

Since fish have a sensitive characteristic of sound, it is possible to distinguish a preferred sound or a avoided sound, and perform an action corresponding to the detected sound.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the embodiments described below are only for explaining in detail that the person skilled in the art to which the present invention pertains can easily implement the invention, thereby limiting the protection scope of the present invention. Does not mean And in describing various embodiments of the present invention, the same reference numerals will be used for components having the same technical characteristics.

1 is a schematic block diagram of a cage farming system according to an embodiment of the present invention.

Referring to FIG. 1, the cage farming system 10 basically includes a control device 200, a sound wave generating device 300, and a sound wave output device 400, a temperature measuring device 100, a storage device 500 It may further include.

In the present invention, the cage farming system 10 provides a method for trapping fish by outputting sound waves to a part of a sea area surrounded by a breakwater and land, and forming a cage area with a sound wave wall formed by the sound waves. The sound wave wall referred to herein is not identified with the naked eye, but means a virtual wall in which paths of sound waves passing through the sea water are collected, and the sound wave wall may be formed from the sea level to the sea floor.

The temperature measuring device 100 measures the water temperature of the sea water, and is installed at an arbitrary sea level from the sea level to the sea water temperature. For example, the temperature measuring device 100 may be installed on the sea surface to measure the daily average water temperature of the sea water.

The control device 200 may determine fish species inhabiting the marine area according to the water temperature measured by the temperature measurement device 100. Fish are warm-blooded animals that are sensitive to the temperature of sea water and have the characteristic of inhabiting only at the proper temperature.

Fish species Proper temperature Black sea bream 13 ℃ ~ 23 ℃ Rockfish 8 ℃ ~ 22 ℃ Red snapper 17 ℃ ~ 20 ℃ Flounder 10 ℃ ~ 17 ℃ Flatfish 18 ℃ ~ 24 ℃ Cuttlefish 18 ℃ ~ 20 ℃

For example, referring to Table 1, black sea bream inhabit at a water temperature of 17 ° C to 20 ° C, and rockfish inhabit at a water temperature of 8 ° C to 22 ° C.

The control device 200 may pre-store fish information inhabitable in the marine area SA and appropriate temperature of the fish, and fish inhabit the marine area SA using the measured water temperature and fish species information Can judge. For example, when the measured water temperature is 19 ° C, the control device 200 may determine that the black sea bream and flounder live in the marine area SA.

In addition, the control device 200 may determine a repelled frequency band disliked by fish determined to inhabit the marine area SA. Here, the repelled frequency band may mean a frequency band of sound waves that a specific fish avoids, for example, a frequency band of sound waves emitted by an upper predator of a specific fish. In addition, since the predation relationship may be different for each fish, the avoided frequency band may also be different. For example, if the fish that is determined to inhabit the marine area SA is a patterned squid, the control device 200 may determine the frequency of the sound wave generated by the red seabream, the upper predator of the patterned squid.

Fish species Audible frequency (Hz) Atlantic salmon 40-350 tuna 100 ~ 900 goldfish 40 ~ 3200 Dae-gu 20 ~ 3800 Red piranha 80 ~ 1500

Further, referring to Table 2, the frequency range of sound waves that can be recognized for each fish may be different. Therefore, the control device can determine the avoided frequency band within the frequency band recognized by the fish.

According to an embodiment, when a plurality of fish inhabiting the environment at the measured water temperature exists, the control device 200 selects the main fish species determined to inhabit the most in the marine area, and the main The frequency bands avoided by fish species may be determined as the avoided frequency bands.

For example, when the control device 200 determines that the fish that inhabit the measured water temperature is a red sea bream and a catfish, it can be determined which fish species of the red sea bream and the catfish live more in the marine area where the cage farming system 10 is implemented. . If it is determined that the number of red snapper is greater than that of catfish, the control device 200 may select the red snapper as the main fish species. Also, the control device 200 may determine a frequency band avoided by the red snapper as a avoided frequency band.

The sound wave generator 300 may generate sound waves having frequencies within a repelled frequency band. The size of the sound waves can be generated to a size that does not affect fish in the cage region.

The sound wave output device 400 may output sound waves generated by the sound wave generation device 300 to seawater in the ocean region. The sound wave output device 400 may be disposed on one side of the breakwater, and may be installed at a plurality of positions on the side of the breakwater.

Since sound waves are transmitted through a medium called water, the longer the transmission distance, the smaller it becomes. Therefore, the size of the sound wave generated by the sound wave generating device 300 becomes smaller as it moves away from the sound wave wall, and may not affect fish in the border region.

The storage device 500 may store information related to fish that can be inhabited in the marine area where the cage farming system 10 is implemented, appropriate temperature for each fish species, information regarding the tide cycle and ebb cycle of the marine area. Such information can be provided from the outside through the Internet network or can be set directly by the administrator.

FIG. 2 is a conceptual diagram of a cage style system according to an embodiment of the present invention, FIG. 3A is a cross-sectional view taken along line I-I 'in FIG. 2, and FIG. 3B is a cross-sectional view taken along line K-K' in FIG. 2.

In FIGS. 2, 3A, and 3B, the shape of the breakwater (BW) is shown as 'a', but is not limited thereto, and the shape of the breakwater (BW) is various such as a diagonal line, a curved line, and a line including straight lines and curves. Can be transformed.

In addition, only the sound wave output device 400 disposed on one side of the breakwater (BW) is shown, but the temperature measurement device 100, the control device 200, the sound wave generation device 300, and the storage device 500 are one. It can be implemented by being integrated into the configuration of, or each can be implemented separately on the breakwater (BW) or land (SH).

In addition, a mesh (not shown) is disposed on the side of the breakwater (BW) to prevent fish located in the cage region from penetrating the breakwater and leaking to the outside ocean.

Also, for convenience of explanation, only three sound wave output devices 400 are shown, but the number of sound wave output devices 400 may be changed according to the depth of the seabed, the flow velocity, the distance between the breakwater (BW) and the land (SH), etc. You can.

2, 3A, and 3B, the sound wave output device 400 may be disposed on one side of the breakwater (BW). The sound wave output device 400 may be disposed near the end of the breakwater BW to form a wider border area CA.

The sound wave output device 400 may be installed on one side of the breakwater (BW) at regular intervals in a direction from the sea surface toward the sea surface, but is not limited thereto. In the section, it may be arranged at a narrower interval.

For example, the sound wave output device 400 may be installed at intervals of 5 m, but when the movement of fish FI is active at a depth of 10 m to 15 m at the seabed, the sound wave output device 400 at 3 m intervals at a depth of 10 m to 15 m at the seabed Can be installed.

The sound wave output device 400 may output sound waves SD having a frequency avoided by the fish FI in order to trap the fish FI inside the edge area CA, and the sound waves due to the output sound waves SD A wall SW can be formed. The sound waves in the water have a characteristic of being transmitted radially, but the sound wave output device 400 according to an embodiment of the present invention uses a superposition characteristic of the sound waves SD to view a specific direction (land (SH) in the breakwater (BW)) The sound wave wall SW may be formed by concentrating the sound wave SD in the viewing direction).

Since the sound wave output device 400 outputs sound waves SD to seawater of all depths from the sea surface to the sea bottom surface, the sound wave walls SW may be densely formed at all depths.

The sound wave SD output from the sound wave output device 400 is generated by the sound wave generator 300 in a frequency band avoided by fish FI inhabiting the marine area SA. Since the intensity of the sound wave SD increases as it approaches the sound wave wall SW, the fishes FI in the cage region CA avoid the action of approaching the sound wave wall SW, and the sound wave wall SW To act away from them.

In addition, since the sound waves (SD) may cause interference with each other, the sound wave output device 400 may output the sound wave (SD) at different points in time depending on the arranged position. For example, the sound waves SD may be sequentially output at a predetermined time interval from the sound wave output device 400 disposed close to the sea surface to the sound wave output device 400 disposed close to the sea surface.

4 is a graph for explaining a cage farming system according to an embodiment of the present invention.

Referring to FIG. 4, a tide cycle and a tide cycle divided based on the average sea level are illustrated. When the Earth rotates and rotates around the Sun, the Moon orbits 13 °. It takes 52 minutes for the Earth to orbit 13 °, and the Moon takes around 24 hours and 50 minutes to return to its original position. Therefore, since the interval between the tide and the next tide (tide cycle) occurs at 12 hours and 25 minutes, the time of occurrence of the tide and the ebb is not always constant and varies slightly every day.

The storage device 500 of the present invention may store information on the tide and ebb of the marine area SA, and the control device 200 may calculate the tide cycle and tide cycle of the seawater using the information.

The control device 200 may limit the generation of the sound wave SD of the sound wave generating device 300 during the first period of the tide period. Here, the first period means any period of the high tide period, and may mean all periods except for the low tide period or a part of the high tide period.

In the high tide period, since the inflow of seawater to the coast increases, more fish (FI) than the low tide period may flow into the marine area (SA) close to the land (SH). Accordingly, the control device 200 may release the generation of the acoustic wave wall SW during the high tide period to allow the fish FI to flow in in order to trap more fish FI in the cage region CA.

That is, during the first period, the output of the sound wave SD from the sound wave output device 400 is interrupted to allow the inflow of fish FI into the cage region CA, and during the rest of the period, the sound wave from the sound wave output device 400 is generated. SD) is output to block the inflow and outflow of fish FI.

5 is a conceptual diagram of a cage farming system according to another embodiment of the present invention.

Referring to FIG. 5, the sound wave output devices 410A, 410B, and 420 may be disposed at a plurality of positions on one side of the breakwater BW.

The sound wave output device 400 includes first sound wave output devices 410A and 410B disposed near the end of the breakwater (BW) and a second sound wave output device 420 disposed inside or inside the breakwater (BW). You can. The first sound wave output devices 410A and 410B output first sound waves SD1A and SD1B in a avoided frequency band avoided by fish FI, and the second sound wave output devices 420 prefer fish (FI) The second sound wave SD2 of the preferred frequency band can be output.

As described above, the avoided frequency band may refer to the frequency of sound waves emitted by an upper predator of fish FI.

Meanwhile, the preferred frequency band may mean a frequency of sound waves generated by a predator of fish FI, that is, a sub-predator of fish FI. However, the present invention is not limited thereto, and the preferred frequency band may be set to a frequency preferred by the fish FI according to other experimental results.

Specifically, when explaining the operation of the cage farming system 10 according to another embodiment of the present invention, the control device 200 determines the fish species inhabiting the environment of the measured water temperature, and avoids the frequency bands for the fish species. The preferred frequency band can be determined.

The sound wave generator 300 may generate first sound waves SD1A and SD1B having repelled frequency bands and second sound waves SD2 having a preferred frequency band.

The first sound wave output devices 410A and 410B may output the first sound waves SD1A and SD1B to form sound wave walls SWA and SWB, and the sound wave walls SWA and SWB may flow in and out of fish FI. Emissions can be blocked.

As described above, the first sound wave output devices 410A and 410B may output the first sound waves SD1A and SD1B to form a plurality of sound wave walls SWA and SWB overlapping, thereby allowing the fish FI to flow in and out. Emissions can be blocked more effectively.

The second sound wave output devices 410A and 420B may output the second sound wave SD2 preferred by the fish FI, and the fish FI gather in a direction in which the intensity of the second sound wave SD2 is strong. Since the second sound wave SD2 does not need to form the sound wave wall SW unlike the first sound waves SD1A and SD1B, the second sound wave output device 400 can radially output the second sound wave SD2. have.

On the other hand, when there are a plurality of fish species inhabited in the environment of the measured water temperature, and the frequency bands to be avoided are different, the control device 200 may determine all the frequency bands each of the fish (FI) avoids as a avoided frequency band have.

The sound wave generator 300 may generate sound waves in a avoided frequency band. If the avoided frequency band includes two frequency bands, the sound wave generator 300 may generate sound waves in each of the two frequency bands.

For example, when there are two fish species living in the environment of the measured water temperature, the control device 200 is a frequency band that each of two types of fish FI avoids, and the first and second avoidance frequency bands are different from each other. The frequency band can be determined. The sound wave generator 300 may generate sound waves of each of the first and second avoided frequency bands.

At this time, the sound wave output device 400 may alternately output sound waves of the first avoided frequency band and sound waves of the second avoided frequency band at the same location. That is, the 1A sound wave output device 410A can alternately output sound waves of the first avoidance frequency band and sound waves of the second avoidance frequency band at regular intervals and output the sound waves of the first avoidance frequency band at the same location. The acoustic wave wall and the acoustic wave wall of the second avoided frequency band may be generated. Accordingly, the acoustic wave wall by sound waves in the first repellent frequency band may be alternately generated at regular time intervals.

According to another embodiment, the sound wave output device 400 may output sound waves of the first avoided frequency rental and sound waves of the second avoided frequency band at different locations. That is, the 1A sound wave output device 410A may output sound waves in a first repelled frequency band, and the 1B sound wave output device 410B may output sound waves in a second repelled frequency band. Accordingly, the sound wave wall SWA by sound waves in the first repellent frequency band and the sound wave wall SWB by sound waves in the second repellent frequency band may be generated at different positions.

6 is a flow chart for explaining the cage style method of the present invention.

Referring to FIG. 6, the cage farming system 10 including the control device 200, the sound wave generating device 300, the sound wave output device 400, and the temperature measuring device 100 is the water temperature of the marine area SA Can be measured.

In addition, the cage farming system 10 can determine the fish species inhabiting the environment of the measured water temperature.

In addition, the cage farming system 10 may determine the frequency bands avoided by fish species.

In addition, the cage farming system 10 may generate sound waves having a repelled frequency band.

In addition, the cage farming system 10 may form the sound wave wall SW in the marine area SA by outputting the sound wave in a direction in which the breakwater BW faces the land SH.

As a result, in the marine area SA between the breakwater BW and the land SH, a caged area CA confined by a sound wave wall SW may be formed, and fish FI introduced into the caged area CA may be formed. The sound wave wall (SW) may be blocked from being discharged to the outside ocean.

7 and 8, in order to avoid overlapping description, description will be made focusing on differences from the above-described embodiment.

Referring to FIGS. 7 and 8, the cage farming system 10 may include first and second breakwaters BWA and BWB disposed protruding from the land SH to the marine area.

A sound wave output device 400 may be disposed on at least one of the first and second breakwaters BWA and BWB. The sound wave output device 400 disposed on one breakwater may output sound waves SD in a direction in which the other breakwater is located. For example, the sound wave output device 400 installed on the first breakwater (BWA) may output sound waves (SD) in a direction in which the second breakwater (BWB) is located.

Meanwhile, although not illustrated in FIGS. 7 and 8, the sound wave output device 400 may be disposed on the second breakwater (BWB), and the sound wave output device installed on each of the first and second breakwaters (BWA and BWB) ( 400) can simultaneously output sound waves in the opposite direction.

Accordingly, a sound wave wall SW due to the sound wave SD may be formed between the first and second breakwaters BWA and BWB, and the land SW and the first and second breakwaters BWA and BWB A border region CA by the sound wave wall SW may be formed therebetween. Fish FI introduced into the cage region CA may be blocked from being released into the external ocean by the acoustic wave wall SW.

Although the embodiments of the present invention have been described above, it is understood that those skilled in the art to which the present invention pertains can perform various modifications without departing from the claims of the present invention.
