  Hereinafter, embodiments of a stationary net fishing tool and a stationary net fishing method according to the present invention will be described with reference to FIGS. 1 to 7.

  FIG. 1 to FIG. 4 show an embodiment of a stationary net fishing tool of the present invention and a fish lamp device used therefor.

  As shown in FIGS. 1 and 2, the stationary network 1 of the present invention is formed in the same manner as a known stationary network that has existed in the past. The stationary net 1 includes a fence net 2, a playground 3, a box net 6 and the like. More specifically, the athletic field 3 is formed in a substantially rectangular shape or the like by a plurality of relatively long straight lines having the upper opening 3a. The fence net 2 erected on a single straight line is formed so that the tip thereof reaches the middle of the net 4 of the sports field 3 or the inside of the sports field 3. The inner part of the ascending field 3 is tapered, and a rising part 5 formed in a cylindrical shape is provided in order. A bottomed bottom part formed in a substantially rectangular shape having an upper opening 6a at the tip of the rising part 5 is provided. A box network 6 is connected. The connecting portion between the ascending 5 and the box net 6 is fixed so that the front end of the ascending 5 forms a box net 7 and the opening at the front end of the ascending 5 reaches the inside of the box net 6. Yes. The ascending port 5 is provided with an ascending port 5a whose bottom surface gradually rises from the athletic field 3 side toward the box net 6 side. Furthermore, a desired bag net (not shown) is disposed at the tip of the box net 6 as necessary. And the stationary net 1 comprised in this way is laid in the desired position of a fishing ground with the appropriate rope, float, anchor etc. which are not shown in figure.

  In the present invention, the fish collection lamp devices 8 are provided on both sides of the upper end portion of the fence net 2 in the vicinity of the net entrance 4, for example, about 50 m away from the net entrance 4. The fish collection lamp device 8 is formed by a power supply unit 9 that can float on a water surface portion and a fish collection lamp 11 that is suspended from the power supply unit 9 with a cable 10 and is installed at a depth of about 5 to 20 m. As the fish collection lamp 11, a halogen lamp, a metal hydride lamp, an LED, or the like may be used, and those having no directivity are preferable. As shown in FIGS. 3 and 4, the power supply unit 9 includes a rectangular box-shaped case 12 that can be opened and closed in an airtight and watertight manner. The case 12 has an open / close lid 12a at the top, and is formed so that it can float on the water surface by a float 13 fixed to the outer periphery of the top. Inside the case 12, two batteries 14 are replaceably installed at the bottom, and power is supplied from the battery 14 to the fish lamp 11 through the cable 10. The battery 14 may be replaced when the fish in the box net 6 is taken out, for example. The two batteries 14 are ON / OFF controlled by a timer 16 provided in the control unit 15. The set time of the timer 16 is the lighting time for collecting the fish near the fence net until the fish lamp 11 is turned on at night to collect the fish and the fish recognizes the fence net 2 at dawn and starts moving. It is good to do. For example, the lighting start time of the fish collection lamp 11 may be about 8 to 10 o'clock, which is the time when the fish feeds at night. It is good to be from 3:00 to 5:00 of the dawn when it recognizes and is guided and begins to move. In addition, examples of fish having fluorescence in light include salmon, salmon, and sea bream. In addition, an air pump 17 is provided in the case 12 for discharging harmful gas such as hydrogen gas that may leak from the battery 14 to the outside of the case. The discharge path 18 led out from the air pump 17 is branched and connected to four exhaust cylinders 19 fixed to the opening / closing lid 12a. Each exhaust pipe 19 is provided with a filter or check valve (both not shown) for preventing the intrusion of seawater. In addition, the air pump 17 is connected to the control unit 15 and is operated and controlled so as to be operated every predetermined time to discharge harmful gases. Although not shown, an adsorbent such as activated carbon or zeolite for adsorbing and removing harmful gases in the case 12 may be incorporated in the case 12. In addition, although the fish collection lamp 11 was installed in the both sides of the fence net 2, only one side may be sufficient.

  Next, a method for catching fish by a stationary net fishing method performed using a stationary net fishing tool having a fish collecting lamp device 8 of the present embodiment will be described.

  By operating the timer 16 in the control unit 15 installed in the power source unit 9 of the fish collection lamp device 8 mounted on the fence 2 portion of the fixed net fishing gear installed as shown in FIGS. At night, the fish collection lamp 11 installed in the vicinity of the fence 2 starts to light up. The fish is collected by the light emitted from the fish collection lamp 11 with no directivity, and the fish is gradually collected near the fish collection lamp 11, that is, in the vicinity of the fence net 2 and stays there. The state of fish collection near the fish lamp 11 is continued until dawn due to the light collecting property of the fish. The fish that has recognized the fence net 2 at dawn is guided by the fence net 2 and moves toward the playground 3, and the fish that enters the playground 3 from the net entrance 4 rises while migrating around the playground 3. 5 is guided into the box network 6. The fish guided into the box net 6 is prevented from returning to the playing field 3 by the box net return 7.

  The timer 16 in the control unit 15 stops the power supply to the fish collection lamp 11 when it is time for the fish to be guided toward the playing field 3 by the fence net 2 at dawn.

  The fish in the box net 6 is taken out by taking out at least once a day. When the fish is taken out, the battery 14 in the case 12 forming the power supply unit 9 of the fish collection lamp device 8 is replaced as necessary so that the fish can be continuously captured by the fish collection lamp 11. Between the setting of the battery 14 and the next replacement, the air pump 17 is intermittently operated by the control unit 15 every predetermined time, and harmful gases in the case 12 pass through the discharge path 18 and the exhaust pipe 19 in order. 12 is discharged outside. Further, harmful gas is adsorbed by the adsorbent loaded in the case 12. Since the air pump 17 and the adsorbent remove the gas, the power supply unit 9 is reliably prevented from exploding, and the safety becomes extremely high.

  In addition, the amount of fish captured on the day when the fixed net fishing gear of the present embodiment is used for the salmon, salmon and urume salmon as fluorescent fish, and on the day when the fish lamp device 8 is not used as in the conventional fixed net The results of performing are shown in FIGS. From FIG. 5 to FIG. 7, it was found that the catch amount in the method of the present invention reached 2 to 4 times the catch amount of the conventional method, and according to the present invention, the catch amount was greatly improved. In a later test, the same effect as floating fish was obtained. Thereby, according to this invention, it became clear that the capture efficiency with respect to the fish with a fluorescent property was made very high.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed. For example, when a battery that does not completely generate harmful gases has been developed, the battery can be replaced with the battery 14 of the present invention. In this case, the case 12 may be formed so as to be completely sealed, and the pump may be omitted.
