Abstract

PROBLEM TO BE SOLVED: To provide a live fish-transferring device which allows live fishes to approach from their heads a waterway formed in a transfer pipe for connecting a transfer-beginning water tank to a transfer-ending water tank, utilizes the swimming forces of the fishes to transfer the heads of the fishes in the transfer direction, and thereby can artificially transfer the live fishes by the use of the inexpensive tool without injuring the fishes. SOLUTION: This live fish transfer device is manufactured by allowing a live fish-breeding transfer-ending water tank B to communicate with water in a fish transfer-ending water tank A through a waterway formed in a transparent transfer pipe 14, and then connecting a live fish-introducing member 21 to the tip of the transfer pipe 14, where the tip of the transfer pipe 14 is submerged in the transfer-beginning water tank B. A water flow which is directed from the transfer-ending water tank A to the transfer-ending water tank B and is weaker than the swimming forces of the live fishes is added to the waterway. The live fishes are gathered in a space between the live fish-introducing member 21 and a facing swimming range-reducing member, and the swimming range-reducing member is allowed to approach the live fish-introducing member 21. Thus, the live fishes direct their heads to the side of the transfer pipe as escaping actions, approach from their heads the bright waterway which is formed in the transfer pipe 14 and spouts out fresh water, and move to the transfer-ending water tank A through the waterway by their self forces.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a live fish transfer apparatus for transferring live fish from a transfer source water area to a transfer destination water area via a water channel formed in a transfer pipe disposed in the air.

[0002]

2. Description of the Related Art Japanese Patent Publication No. 7-112399 discloses a "live fish separation method and apparatus" by the present inventor. Here, there are provided a movable element which can move back and forth in the transfer source water tank and which can move close to and away from the opening of the water channel communicating with the transfer destination water tank, and a second movable element which can move in and out of the water path. The water is transferred from the transfer source water tank to the transfer destination water tank through a water channel formed in the connecting member. However, as a means for directing the head of the fish toward the waterway, a moving element capable of moving back and forth in the transfer source tank and a water passage capable of lighting are provided, and as a means for moving the fish from the head into the waterway, it is possible to move back and forth in the transfer source tank. In addition, there is a second moving element that can move back and forth in the waterway as a means for advancing the fish that has entered the waterway. The waterway cannot be found quickly and the time to reach the waterway is long. In addition, the material of the moving element is not limited, and if the moving element is made of net material, the fish does not go to the waterway but faces the moving element and evacuates to the outside of the moving element by plunging its head into the mesh and escaping to the outside of the moving element. Take. Furthermore, when a large amount of fish is sent to a stationary water channel formed in the connecting member, when the fish is moved into the transfer destination water tank, some fish and fish species temporarily turn their bellies to heaven. Also, if there is no second mover, some fish that enter from the head stop in the waterway and do not try to advance on their own,
There was a problem that the type of fish used was limited.

Therefore, as a means for forcing fish into a water channel and forcibly moving the fish that has entered, a technique of sending a fish by applying a water flow in a direction in which the fish is to be transported to a water channel formed in a transfer pipe is special. No. 57-184022 discloses a method and a device for transferring live fish, in which a worker holds the tip of a transfer pipe at a place where live sardines are gathered in a sardine storage network. The live sardine is sucked together with seawater from the end of the transfer pipe. However, the lack of means to direct the head of the fish toward the inlet of the suction pipe, means to enter the suction pipe from the head, and means to advance the fish that has entered the waterway from the head, so that the live fish will not be washed away. There is a habit of swimming with the head on the upstream side of the flow, and the escape behavior continues with the caudal fin facing the suction port of the transfer pipe with the suction flow. At this time, if the swimming power of the live fish is weaker than the suction power in the transfer pipe,
The live fish is sucked into the transfer pipe and is transferred by the caudal fins flowing in the transfer direction (downstream of the flow). However, if the swimming power of the live fish is stronger than the suction power, the live fish will not be sucked into the transfer pipe. Therefore, this technique has a problem that it is limited to the transfer of fish with weak swimming ability. Further, there is a problem in that the suction power is drastically reduced when the fish is separated from the suction port by a certain distance or more, so that the fish separated by a certain distance from the suction port cannot be sucked. Furthermore, since the fish are swept up with their fins facing the flow while moving their caudal fins in the transport direction, the posture is not stable and the transport speed is not stable. Therefore, when a plurality of fish are sucked at the same time, the fish are likely to be clogged in the transfer pipe. Also,
There is a problem that it cannot be applied to a counting device for swimming fish or a measuring device such as body surface observation.

A technique for automatically increasing the density of fish in the vicinity of the suction port is disclosed in Japanese Utility Model Publication No. Hei 2-9656, “Fishing Fish Pump Device”. A donut-shaped tank is attached to
A funnel portion is provided on the lower surface of the tank, and the suction port of a suction pipe connected to a fish pump is opened in the funnel portion to float a donut-shaped tank, thereby reducing the swimming range of the fish in the net to reduce the swimming range of the fish in the net. The accommodated live fish is sucked through the suction port of the suction pipe. However, although the improvement in the point that the density of fish near the suction port is automatically increased and the fish are easily sucked is recognized as similar to the floating of a donut type tank, similar to the above-mentioned reference, the fish is inserted from the head into the suction pipe in the traveling direction. Lack of the technical idea of moving fish with the head turned, only fish with a weaker swimming power than the suction power can be sucked. Therefore, there is a basic problem that this technique is also limited to the transfer of fish with weak swimming ability. However, in this technology, live fish contained in a container-like net are desperately evacuating as they do not get sucked into the dark suction pipe waterway as the fish swimming range of the fish inside the net decreases due to the floating of the donut type tank As a result, there is a problem that the fish is scratched because the tail fin is pointed toward the suction pipe and the head is squeezed into the mesh to escape from the mesh through the mesh of the mesh, and still escapes. Further, in such a panic state, there is a problem in that the density of fish that is not sucked increases, and the fish come into contact with each other, causing severe abrasion. Furthermore, in order to increase the range of fish that can be sucked, it is necessary to increase the capacity of the suction means, but this has a problem that the apparatus becomes large and expensive.

[0005]

In addition, A is a transfer destination water tank to which fish are transferred, and B is a transfer source water tank in which fry or adult fish that have come to swim in a school are bred.

The operation of the above configuration will be described with reference to FIGS. When various devices are arranged as shown in FIG. 1 and a start switch (not shown) is turned on, (1) in FIG.
As will be understood from the above, the self-priming pump 15 is operated, and the air existing in the hollow portions of the tube 38, the third directional switching valve 17, the first directional switching valve 16, and the tube 32 is sucked by the self-priming pump 15, The exhaust gas is exhausted to the rear chamber 4 via the 33, the second directional switching valve 18, the tube 35, the four-way directional switching valve 19, and the tube 35, and further exhausted to the outside of the main body 1 from the vacuum breaking valve 41. (The air may be exhausted from the distal end of the tube 34 via the tube 33, the second directional switching valve 18, and the tube 34.) Thereafter, the tube 38, the third directional switching valve 17, the first directional switching valve 16, and the tube 32 When the air in the hollow portion is replaced by water entering from the transfer source water tank B, the water is replaced by the tube 3.
3, is supplied to the rear chamber 4 via the second directional switching valve 18, the tube 35, the four-way hitting directional switching valve 19, and the tube 35. Water is supplied to the rear chamber 4 to raise the water level. When the water reaches the position of the float switch 40 provided in the front chamber 3, the float switch 40 detects the water level and sends the information to a controller (not shown). The first directional control valve 16 and the second directional control valve 18 are switched by acting on a solenoid (not shown), and the vacuum break valve 41 is closed.

Then, as can be seen from FIG. 2 (2), the air present in the transfer pipe 14, the hollow portion of the front chamber 3 passes through the tube 31, the first directional control valve 16 and the tube 32, and the self-priming pump 15 And exhausted from the distal end of the tube 34 via the tube 33, the second directional switching valve 18, and the tube 34. As a result, the pressure in the transfer pipe 14 and the hollow portion of the front chamber 3 is greatly reduced, the water in the transfer source water tank B enters the hollow portion of the transfer pipe 14, and the water level gradually rises. As the water level in the transfer pipe 14 rises, the air in the transfer pipe 14 and the front chamber 3 is completely exhausted, and the water entering from the transfer pipe 14 becomes hollow in the transfer pipe 14, the front chamber 3, and the rear chamber 4. When the part is filled, the water is
1. The air is sucked by the self-priming pump 15 via the first directional switching valve 16 and the tube 32, and discharged from the distal end of the tube 34 via the tube 33, the second directional switching valve 18 and the tube 34.

Subsequently, the first directional control valve 16, the third directional control valve 17, and the second directional control valve 18 are switched to each other so that the distal end of the first directional control valve 16, the third directional control valve 17, and the second directional control valve 18 are immersed in the water in the water tank B as shown in FIG. Submerged tube 38, third directional control valve 17, tube 3
8. The self-priming pump 15 sucks water through the first directional switching valve 16 and the tube 32 and passes through the tube 33, the second directional switching valve 18, the tube 35, the fourth directional switching valve 19, and the tube 35. The water is discharged into the rear chamber 4. Thus, the water is returned from the transfer pipe 14 to the transfer source water tank B via the front chamber 3. At this time, the flow velocity of the water flowing toward the transfer source water tank B in the water channel formed in the transfer pipe 14 is adjusted by the flow rate control valve 20 to be smaller than the swimming power of the fish swimming in the transfer source water tank B.

Subsequently, as shown in FIG. 3D, when the swimming range reducing means 22 is moved toward the live fish introduction member 21, the fish gradually moves toward the live fish introduction member 21 side. At this time, the fish swims with its head directed toward the transfer pipe due to the escape behavior from the swimming range reducing means 22 and the habit of opposing the water flowing out of the transfer pipe 14. At this time, the swimming range reducing means 2
2 and the live fish introduction member 21 are made of a water-tight material, so that the fish has an effect of surely taking an escape action. (Swimming range reduction means 22
If the live fish introducing member 21 is made of a porous material such as a net, the fish often try to escape from the hole and continue to swim by piercing the mouth into the hole formed in the live fish introducing member or the swimming range reducing means). Fish that feel a sense of danger that the row area is reduced will feel the depth of the waterway formed in the transfer pipe 14 and select it as a retreat place, and will eventually enter the waterway formed in the transfer pipe 14 from their heads. Although the lighting device 12 is turned off through the transfer pipe 14 and enters the darkened front room 3,
The fish having a habit of seeking brightness immediately moves and retreats to the room 4 after the lighting device 13 is turned on to make the fish bright.

A means for detecting the density of the fish in the rear chamber 4 (not shown) detects the density of the fish, and when the density exceeds a preset density, the information is sent to a controller (not shown), and the controller works on a solenoid (not shown) to control the direction. By switching the switching valves 17 and 19, as shown in FIG. 4 (5), water is sucked from the transfer source water tank B and the rear chamber 4, while the water is supplied to the front chamber 3 and the rear chamber 4, and the air cylinder is supplied. 11, the first shutter 10 is lowered to close the hole 2a in a watertight manner. The lighting device 12 is turned on. This allows
Fresh water from the transfer source water tank B is supplied to the sealed rear chamber 4 and the same water is supplied to the water channel formed in the transfer pipe 14 via the front chamber 3, so that the fish is continuously transferred. It moves into the bright front room 3 through the pipe 14.

When the first shutter 10 closes the hole 2a in a water-tight manner, the information is sent to a controller (not shown), and the controller works on a driving means (not shown) so that the second shutter, as shown in FIG. 8 is pivoted to open the outlet 9 and the lighting device 13 is turned off. As a result, the fish enters the sunlight from the room 4 after darkening, and moves and retreats to the transfer destination water tank A having a bright and open feeling.

When the fish density detecting means detects that the fish is no longer in the rear chamber 4, the information is sent to a controller (not shown), and the controller works on a driving means (not shown), and as shown in (7) of FIG. As shown, the second shutter 8
Is pivotally closed to close the outlet 9 in a watertight manner and the lighting device 1
3 is turned on.

Subsequently, as shown in FIG. 5 (8), after the illumination device 12 is turned off and the air cylinder 11 is operated to raise the first shutter 10 to open the hole 2a, the direction is switched. Valves 17 and 19 are switched to transfer source tank B
Is sucked into the rear chamber 4. At this time, the first
The gap existing between the edge of the shutter 10 and the inner wall of the front chamber 3 and the first shutter 1 at the rising end of the first shutter 10
The gap between the upper surface of the room 0 and the ceiling of the front room 3 is larger than the height of the fish entering the room, so that the fish
The shutter 10 easily moves and moves to the rear chamber 4.

In this way, after the required fish are transferred to the transfer destination tank A by repeating (4) of FIG. 3 to (8) of FIG. 5, each device is returned to the original position, and then the vacuum break valve is opened. When 41 is switched to open the front room 3 to the atmosphere, a part of the water in the room is transferred by the gravity from the transfer source water tank B through the transfer pipe 14.
Is returned to. Thereafter, the live fish transfer device is moved to an appropriate position, the second shutter 8 is opened, the outlet 9 is opened, and the main body 1 is opened.
Drain the remaining water inside to prepare for the next transfer.

As described in detail above, the means for directing the head of the fish to the entrance of the transfer pipe 14 includes the water flow discharged from the transfer pipe 14 to the transfer source tank B, the live fish introduction member 21 and the swimming range reducing means 22. Further, as means for entering the transfer pipe 14 from the head, there is provided a transfer pipe 14 capable of lighting, a water flow discharged from the transfer pipe 14 to the transfer source water tank B, a live fish introduction member 21, and a swimming range reducing means 22.
As a means for advancing the fish that entered the waterway from the head, it is limited to fish that can swim on their own, but the water is less than the swimming force of the fish facing the traveling direction with the transfer pipe 14 capable of lighting The fish can swim in a natural posture on its own, minimizing stress on the fish and not damaging the fish, by enabling the formation of a stream of water close to. Further, there is an effect that the energy for transferring the fish may be small.

It should be noted that the fry having a weak swimming ability is opposed to the water flow from the transfer pipe 14 toward the transfer source tank B, and the transfer pipe 14
May not be able to proceed along the water channel formed in the river. At this time, as shown in FIG. 2 (2), the tube 31, the first directional control valve 16, and the tube 3 are filled with water in the transfer pipe 14 and the hollow portion of the main body 1 by the self-priming pump 15.
When the water is sucked by the self-priming pump 15 through the tube 2 and discharged from the distal end of the tube 34 through the tube 33, the second directional switching valve 18, and the tube 34, the transfer source water tank B
Is sucked into the main body 1 through the transfer pipe 14. This suction speed can be adjusted by a flow control valve (not shown) that can be connected to the tube 33 between the self-priming pump 15 and the second directional switching valve 18. As a result, the fry collected at the distal end of the transfer pipe 14 is sucked and forcibly transferred into the front chamber 3 of the main body 1 via the transfer pipe 14. Thereafter, the fry moves to the rear chamber 4 that is illuminated as in the above-described embodiment, and moves to the transfer destination water tank A in the same manner as described above. (The fry isolated in the rear chamber 4 opens the outlet 9 and discharges the water sucked from the transfer source water tank B from the tube 37 to the rear chamber 4, and the fry is transferred from the rear chamber 4 to the transfer water tank A by the water flow. (In this case, the third directional control valve 17 is switched so that the water in the rear chamber 4 is not sucked by the tube 37.)

Further, it is possible to suck an adult fish having a strong swimming power. At this time, the inner diameter of the transfer pipe 14 is set to about half the length of the body so that the adult fish cannot change direction,
After the water is spouted from the transfer pipe 14 to cause the fish to enter the water channel formed in the transfer pipe from the head, the direction switching valve is switched to generate the suction water flow. The water is transferred into the front chamber 3 of the main body 1 via the transfer pipe 14 and moved to the transfer destination water tank A in the same manner as in the previous embodiment.

As described above, the live fish transfer device of the first embodiment can freely generate a suction flow or a spout flow according to the swimming power of the fish, so that the size of the fish body from fry to adult fish is not limited. It has an outstanding effect of transferring a wide variety of fish species.

In the above embodiment, the self-priming pump 15 is used for both the means for reducing the pressure in the transfer pipe 14 and the hollow portion of the main body 1 and the means for discharging the water replaced by the reduced pressure. is not. That is, as shown in claim 1, a vacuum pump is used as a means for reducing the pressure in the hollow portion,
It goes without saying that a submersible pump or a pump that requires priming may be used as a means for discharging the replaced water. In this case, there is a drawback that the pump equipment is a vacuum pump and a water discharge pump, and the space is doubled, but there is also an advantage that a pump having an appropriate exhaust (discharge) capability can be selected.

Further, in the above embodiment, the lighting device is used as the lighting means for the room 3 and the rear room 4, but the invention is not limited to this. That is, a part or most of the wall facing the outside of the front room 3 and the rear room 4 is made of a transparent material so that the inside of the hollow part can be lit, and the transparent wall can be concealed by a light shielding member.
If necessary, the transparent wall may be hidden by a light shielding member.

It is preferable that the inside diameter of the transfer pipe 14 in a certain portion be a size that does not allow the fish to change its direction. In this way,
After the self-priming pump 15 is operated to replace the air in the hollow portion of the transfer pipe 14 with water to form a water channel and stop the self-priming pump 15, the lid 80 is closed and the water in the transfer source water tank B is closed. Darkens, the fish turns its head to the bright wire mesh pipe 55. Further, fresh water passes from the outside and light enters, and the fish enters the hollow portion of the bright wire mesh pipe 55 from the head and proceeds in series. Next, when the means for detecting the number of fish that have entered the wire mesh pipe 55 (not shown) detects the number of fish in a preprogrammed range and sends a signal to the controller (not shown), the controller operates the self-priming pump 15 again to transfer the fish. The water in the water channel of the pipe 14 is sucked and discharged from the tube 34. As a result, the fish in the waterway of the transfer pipe 14 and the wire mesh pipe 55 in which the suction flow is generated are sucked and proceed from the head while trying to change the direction, but return to a natural posture as soon as encountering the counterflow and remain as it is. Move to the destination water tank A.

In the above embodiment, as a means for allowing fish to enter the transfer pipe from the head, the water in the transfer source water tank B is darkened while the water channel formed in the transfer pipe 14 is merely brightened. A swimming range reducing member similar to that of the first embodiment is disposed so as to be able to approach and separate toward the entrance of the wire mesh pipe 55 with the lid 80 closed, and is provided outside the swimming range reducing member and the transfer source water tank.

Another embodiment of the means for causing the fish to enter the transfer pipe from the head will be described with reference to FIG. Means for allowing the fish to enter the transfer pipe from the head include a float 87 which is suspended in the water from the floatable surface, is opened on the top side, and is opened so that the fish can pass through the bottom surface (or side surface). And a transfer pipe 14 made of a transparent material which is connected to a bottom (or a side surface) of the hollow body 85 and is connected to an opening through which fish can pass.
And a lid 86 made of a material having a light blocking ratio of 70% or more, which can open and close the top opening. At this time, the hollow body 85
When a buoyant body made of a flexible material that is expandable and contractable by the supply of compressed air is connected to the outer periphery of the bottom of the hollow body and the compressed air is supplied, the buoyant body expands and the bottom surface of the hollow body 85 rises to float the fish. To be able to reduce the swimming range,
It goes without saying that a swimming range reducing member capable of floating up and down the hollow portion of the hollow body 85 may be provided so that the swimming range reducing member may be lowered to reduce the swimming range of the fish.

Further, still another embodiment of the means for causing the fish to enter the transfer pipe from the head will be described with reference to FIG. The means for allowing the fish to enter the transfer pipe from the head is made of a material having a light-shielding rate of 100%. A partition 81 made of a material, through which a hole through which fish can pass is opposed to the outlet, and
A pipe 82 made of a mesh wall, which is bridged between a water tank B made of a watertight material and a partition wall 81 and an inner wall of the water tank B provided with the pipe and communicates the outlet with the hole. It comprises a transfer pipe 14 made of a transparent material connected to the side surface and communicating with the outlet, and a lid 80 facing the partition wall and capable of opening and closing the opening of the hollow portion in which the fish is stored.

By disposing a movable element that can move back and forth in the waterway in the waterway formed in the transfer pipe of the above embodiment, the fish that has moved through the waterway is temporarily turned upside down. In addition to the conventional effect that there is no fish or fish species to aim at and the fish in the waterway can be moved reliably, there is also the effect that the fish moves faster than the moving speed of the moving element, so that the speed of live fish transfer can be increased. .

[0054]

As described in detail above, the live fish transfer device of the present invention has a habit of orienting the head in a direction against which the fish faces the flow.
In addition, since the apparatus is made using a habit of moving in search of brightness rather than darkness, a live fish moves by itself in a natural motion. This simplifies the means for moving live fish.
In addition, the live fish can be transported without being damaged. Furthermore, if it is an adult fish that can swim on its own, even an adult fish having a large body can be transferred, so that the versatility is extremely high. Furthermore, the present invention has practically excellent effects such as application of a high-precision measuring device.
