  The case 102 is a container-like member forming the outer shape of the aquatic organism induction device 100. The case 102 accommodates the electrode 104. As the case 102, for example, an insulating material such as a resin can be used. In the present embodiment, the case 102 has a relatively thin rectangular parallelepiped shape. That is, although the case 102 has a rectangular shape when viewed in plan from the front, it is not limited thereto. For example, the case 102 may have a circular shape, another polygonal shape, or the like when viewed in plan from the front. Further, as shown in FIG. 2, the case 102 has a hollow structure, but the case 102 is not limited to this and may not have a hollow structure.

  As shown in FIG. 1A, the case 102 has a first surface 102A on its front side. In addition, as shown in FIG. 1B, the case 102 has a second surface 102B on the rear side.

  The first surface 102A is a surface facing the inside of the water tank 20 (see FIG. 3). The first surface 102 </ b> A has an opening 103 for exposing the electrode 104 and a protection portion 105 for preventing external contact with the electrode 104. In the example shown in FIG. 1A, the first surface 102A has a rectangular opening 103, and in the opening 103, a protective portion for preventing contact with the electrode 104. 105 are provided. In the example shown to (a) in FIG. 1, the protection part 105 has comprised the grid | lattice form because two vertical frames 105a and three horizontal frames 105b mutually orthogonally cross. The openings 103 are divided by the protection unit 105 into a plurality of (4 × 3 rows) openings 103. In the example shown in FIG. 1A, each of the plurality of openings 103 has a rectangular shape, but the present invention is not limited to this. For example, each of the plurality of openings 103 may have a circular shape, another polygonal shape, or the like. Note that each of the plurality of openings 103 preferably has a size such that the aquatic organism 30 does not touch the electrode 104, and more preferably has a size such that the finger of the worker does not touch the electrode 104.

  The second surface 102 B is a surface facing the inner peripheral surface of the outer peripheral wall portion 22 of the water tank 20. The second surface 102B is entirely covered by the insulating material. That is, the second surface 102B does not have an opening for exposing the electrode 104.

  The electrode 104 is housed in the case 102 such that one side faces the first side 102A and the other side faces the second side 102B. The electrode 104 is supplied with power for inducing the aquatic organism 30 in the water tank 20.

(Configuration of aquatic organism induction system 10)
FIG. 3 is a view showing the configuration of the aquatic organism induction system 10 according to the first embodiment of the present invention. As shown in FIG. 3, the aquatic organism induction system 10 is configured to include a plurality of aquatic organism induction devices 100, a water tank 20, a power source 140, a controller 150, a foot switch 160, and an indicator lamp 170.

  The water tank 20 is configured to have an outer peripheral wall 22 and a bottom 24, and is shaped like a container whose upper side is open. In the water tank 20, water 40 and aquatic organisms 30 are accommodated. The water tank 20 uses, for example, a metal material (for example, stainless steel). However, the present invention is not limited to this, and the water tank 20 may use other conductive materials (for example, aluminum, copper, etc.), and other insulating materials (for example, glass, FRP, etc.) It may be one. Moreover, in the example shown in FIG. 3, although the water tank 20 is carrying out elliptical shape, when it planarly views from upper direction, it does not restrict to this. For example, the water tank 20 may have a rectangular shape, a circular shape, another polygonal shape, or the like when viewed in plan from above.

  The plurality of aquatic organism guidance devices 100 are installed along the inner peripheral surface of the outer peripheral wall 22 of the water tank 20 so as to be close to the inner peripheral surface. In the example shown in FIG. 3, a part of the inner peripheral surface of the outer peripheral wall 22 of the water tank 20 so that the plurality of (14) aquatic organism guidance devices 100 surround a predetermined partial area 20A in the water tank 20 It is installed over the range of Not only this but several aquatic organism guidance devices 100 may be installed over the perimeter of the inner skin of peripheral wall 22 of water tank 20 so that the whole field in water tank 20 may be surrounded.

  The power supply 140 supplies power (DC power) to the control device 150. In the present embodiment, an alternating current power supply (for example, a commercial power supply etc.) is used as the power supply 140. Not limited to this, a DC power supply (for example, a battery or the like) may be used as the power supply 140.

  The control device 150 is an example of “control means”. The control device 150 is electrically connected to the electrodes 104 of each of the plurality of aquatic organism guidance devices 100 via the wiring 152. The controller 150 can apply power to each of the electrodes 104 of the plurality of aquatic organism induction devices 100 using the power supplied from the power source 140. For example, control device 150 generates a second voltage (e.g., 30 V) for output by an AC-AC converter included in control device 150 with AC power of a first voltage (e.g., 100 V) supplied from power supply 140. Converted to AC power of Then, the control device 150 applies the AC power of the second voltage to each of the electrodes 104 of the plurality of aquatic organism induction devices 100.

  The control device 150 classifies the plurality of aquatic organism induction devices 100 into a plurality of combinations as one combination of two aquatic organism induction devices 100 facing each other. And the control apparatus 150 applies the alternating current power from which the polarity of a voltage mutually differs with each aquatic organism induction apparatus 100 and the other aquatic organism induction apparatus 100 with respect to each combination. For example, when applying alternating current power of a voltage of positive polarity to one of the aquatic organism induction devices 100, the control device 150 applies alternating current power of a voltage of negative polarity to the other aquatic organism induction device 100. On the other hand, when applying the alternating current power of the voltage of-polarity to one aquatic organism induction device 100, the control device 150 applies the alternating current power of the voltage of positive polarity to the other aquatic organism induction device 100 . Thereby, the control device 150 transmits the electricity between the one aquatic organism induction device 100 and the other aquatic organism induction device 100 in the water, whereby the one aquatic organism induction device 100 and the other aquatic organism are induced. An electric field can be created in the area between the bioinducer 100.

  Here, the control device 150 is configured to control the power based on the power setting value (for example, voltage, current, frequency, duty ratio, etc.) suitable for controlling the specific aquatic organism 30 into each of the plurality of aquatic organism induction devices 100. Can be applied to the electrode 104 of the

  For example, the controller 150 can set a relatively small voltage value when the size of the aquatic organism 30 to be induced is relatively small. Also, for example, when the size of the aquatic organism 30 to be induced is relatively large, the control device 150 can set a relatively large voltage value. Also, for example, the control device 150 can set a frequency and a duty ratio that are sensitive to the aquatic organism 30 to be induced.

  In particular, the control device 150 makes it possible to set the voltage value (for example, 30 V or less) which does not lead to the death and damage of the organism while enabling the aquatic organism 30 to be electrically stimulated. Thereby, the aquatic organism induction device 100 of this embodiment can be induced in a predetermined direction by electrical stimulation in the water tank 20 without killing and damaging the aquatic organism. Therefore, the aquatic organism induction device 100 of the present embodiment can induce aquatic organisms in a living state.

  The control device 150 may be capable of changing the power setting (for example, voltage, current, frequency, duty ratio, etc.) of the power applied to each of the electrodes 104 of the plurality of aquatic organism induction devices 100. In this case, the control device 150 can target various kinds of aquatic organisms 30 by changing the power setting of the power applied to each electrode 104 according to the aquatic organisms 30 to be guided. It becomes possible. Further, in this case, the control device 150 sets each of the electrodes 104 such that the electric field strength is suitable according to various factors of the electric field strength such as the size of the water tank 20 and the arrangement interval of the aquatic organism induction device 100. It is also possible to change the power setting of the power applied to the

  Further, the control device 150 may be capable of selectively switching the aquatic organism induction device 100 which applies power to the electrode 104 among the plurality of aquatic organism induction devices 100. In this case, the control device 150 can change the region forming the electric field in the water tank 20 by selectively switching the aquatic organism induction device 100 which applies power to the electrode 104.

  For example, the setting change of the control device 150 may be performed by changing means (for example, a dip switch or the like) provided on the main body of the control device 150. Further, for example, the setting change of the control device 150 may be performed from an external device (for example, a personal computer, a smartphone, a tablet terminal, or the like) connectable to the control device 150.

  The AC power applied to each electrode 104 may be a rectangular wave or a sine wave. Further, the frequency of the AC power applied to each electrode 104 may change in time series with a predetermined frequency (for example, 1 KHz) as the center frequency. Thereby, the aquatic organism induction device 100 can induce various aquatic organisms 30 with various peak frequencies of sensitivity to electric power by the electric field formed by each electrode 104. In this case, the frequency of the AC power applied to each electrode 104 may be switched to a plurality of predetermined frequencies in order or may be switched at random.

  The foot switch 160 is electrically connected to the controller 150. The foot switch 160 is an example of a “manual switch”, and switches on and off the power applied by the controller 150 to each electrode 104 of the plurality of aquatic organism induction devices 100. For example, when the foot switch 160 is not pressed, the controller 150 does not apply power to each of the electrodes 104 of the plurality of aquatic organism induction devices 100. On the other hand, when the foot switch 160 is pressed, the control device 150 applies power to each of the electrodes 104 of the plurality of aquatic organism induction devices 100.

  The indicator lamp 170 lights up according to the operating condition of the aquatic organism guidance system 10. For example, the indicator lamp 170 is configured to have a green lamp, a yellow lamp, and a red lamp. In this case, for example, when the power of the aquatic organism induction system 10 is ON and is not applied to each electrode 104 of the plurality of aquatic organism induction devices 100, the green lamp is turned on. Also, for example, when the power of the aquatic organism induction system 10 is turned on and the indicator lamp 170 is applied to the electrodes 104 of the plurality of aquatic organism induction devices 100, the indicator lamp 170 is a green lamp and The yellow lamp lights up. Also, for example, the indicator lamp 170 lights up in red when the aquatic organism guidance system 10 is in a failure state.

That is, each of the plurality of aquatic organism guidance devices 100 is installed such that the second surface 102 B of the case 102 in which the electrode 104 is covered faces the inner peripheral surface of the outer peripheral wall 22 of the water tank 20. Ru.

  Thereby, even when a conductive material (for example, stainless steel) is used for the water tank 20, in each of the plurality of aquatic organism induction devices 100, the electricity transmitted from the electrode 104 is the outer peripheral wall of the water tank 20. It can be prevented from being transmitted to the part 22. Further, in each of the plurality of aquatic organism induction devices 100, contact from the outside (contact of aquatic organisms 30, contact of workers, etc.) with the electrode 104 is made by the protection unit 105 provided on the first surface 102A.

Therefore, the controller 150 does not apply power to each electrode 104 of the plurality of aquatic organism induction devices 100. Therefore, as shown in FIG. 5A, the electric field is not formed in the region 20A, and the aquatic organism 30 can stay in the region 20A.

  On the other hand, FIG. 5 (b) shows a state in which power is applied to each of the electrodes 104 of the plurality of aquatic organism induction devices 100. For example, when the number of aquatic organisms 30 staying in a predetermined partial area 20A in the water tank 20 is relatively large, the worker presses the foot switch 160. Thereby, the control device 150 applies power to each electrode 104 of the plurality of aquatic organism induction devices 100. At this time, for each combination of aquatic organism induction devices 100 (combination of two aquatic organism induction devices 100 facing each other), the control device 150 includes one aquatic organism induction device 100 and the other aquatic organism induction device 100 Then, AC powers having different voltage polarities are applied. As a result, as shown in FIG. 5 (b), a plurality of electric fields e (electric fields e for each combination of the aquatic organism induction device 100) are formed in the area 20A, and the aquatic organisms 30 staying in the area 20A are electric fields.
