Description

  The present invention relates to a live fish transport container used for transporting live fish alive for a long period of time, and particularly to a live fish transport container used for transporting live fish by catching fish or fry that have been captured during fishing. .

  In order to transfer the live fish to the destination while keeping the live fish alive, for example, after putting the live fish in a resin bag, oxygen is injected and sealed. However, once the plastic bag was opened, the oxygen in the bag escaped and the survival rate was low, and if it was torn, it was cumbersome and unusable. For these reasons, several inventions of live fish transport containers that replace resin bags have been proposed (for example, Patent Documents 1 and 2).

Utility Model Registration No. 3080387 JP 2003-125671 A

However, the live fish carrying and breeding container according to the invention of Patent Document 1 does not have an air supply means, and when the live fish captured by fishing or the like is transported over several hours, naturally, the survival rate of the live fish is low. Expected. It was unsuitable for long-distance fishing.
In addition, the invention of Patent Document 2 is a foamed resin live fish transport container used together with an air supply means composed of an air pump, an air disperser, and an air hose connecting the two, and a container main body forming a water tank, It consists of a lid that fits and locks in a watertight manner, and at least one pump storage chamber is provided separately from the water tank in the container body, and a projection that fits in the pump storage chamber is formed on the back of the lid. Furthermore, an air hose that connects the air pump housed in the pump housing chamber and the air disperser installed in the water tank can be fitted between the upper end surface of the pump housing chamber and the back surface of the lid in an airtight manner. A live fish transport container characterized by having an opening formed therein is proposed, but has the following problems. Although air supply means is provided, there is a possibility that air bleeding will be insufficient. Dissolved oxygen consumed by live fish in the water is replenished by the air supply means, but the exhaust air is merely “the vent 62 communicating with the water tank is formed”. Seawater is easy to foam, and when live fish captured by fishing etc. in the live fish transport container of Patent Document 2 is transported together with seawater and transported to the vehicle, there is a possibility that the air holes may be blocked by the foam. There was a high possibility that the ventilation holes would not perform the air bleeding function. Also, when transported by car, there was a problem that seawater in the live fish transport container swelled due to vibration during traveling and the seawater spilled into the passenger compartment from the vent. Furthermore, the air supply means of Patent Document 2 is composed of an air pump, an air disperser, and an air hose connecting both, and the apparatus is large. In addition, a pump storage chamber in which the air pump is isolated is provided, which complicates the structure and reduces the effective space for storing live fish in the container.

  And many fish have developed the running ability to swim against the flow, but there has never been a transport container that forms a horizontal flow of water in the container. The flow of water in a container produced by conventional air pumps, air dispersers and the like including Patent Document 2 causes convection in the vertical direction, and it is difficult for fish to swim. Not only those that use air compressors, but those that drop water from the top also caused a heavy burden on the fish because the water flow in the vertical direction.

  The present invention solves the above-mentioned problems, and by forming a horizontal flow of water in the container, the live fish is energized to improve the survival rate.

An enlarged sectional view is shown.

  The live fish transport container includes a container A, a water flow forming means 5, an air supply means 3, and an air venting tool 4. The container A includes a container body 1 and a lid body 2, and a lid body 2 that closes the upper surface opening 10 of the container body 1 into which water is put is detachably attached.

  The container main body 1 is a general-purpose plastic container A having a substantially hollow rectangular shape as shown in FIGS. 1 to 3, and has a main part for storing water by a rectangular bottom plate part 11 and a side plate part 12 standing from its peripheral edge. Form. An upper plate portion 13 extends from the upper edge of the side plate portion 12 and forms a box shape leaving a circular upper surface opening 10 at the center of the upper surface in plan view. Although the capacity | capacitance of the container main body 1 of this embodiment shall be 100 liters, it can change suitably according to a use. For example, a 500 to 1000 liter container body 1 is employed for fry release. A flange portion 14 extends upward from the periphery of the upper surface opening 10, and a male screw portion 141 is provided on the outer peripheral surface of the flange portion. Here, the upper direction in the present invention refers to the upper direction on the paper surface in the state of the container A in FIG. 2 that is normally placed with the bottom plate portion 11 facing down, the lower direction refers to the lower direction on the paper surface, and the horizontal direction refers to the figure. 2 horizontal directions. Reference numeral 18 denotes a drainage nozzle provided near the bottom plate portion 11, and reference numeral 19 denotes a cap of the drainage nozzle.

The lid body 2 is a lid body 2 in which a circular portion having a size that covers the upper surface opening 10 and a short cylindrical protruding edge portion that is bent and extends downward from the outer peripheral edge of the circular portion. A female threaded portion 21 is formed on the inner peripheral surface of the projecting edge, and the female threaded portion is screwed into the male threaded portion 141, whereby the lid body 2 closes the upper surface opening 10 and is integrated with the container body 1. When the lid body 2 is integrated with the container main body 1, the container A becomes a sealed tank except for a conduction portion by the air bleeding tool 4.
The lid 2 is provided with a viewing window 2b made of a transparent plate at least partially. The live fish 8 accommodated in the container 15 can be seen from the outside of the container A in which the lid body 2 is attached to the upper surface opening 10 of the container body 1 through the viewing window 2b. The lid body 2 here forms a circular hole in the center of the circular portion. Then, a viewing window transparent plate that is one size larger is placed on the circular portion so as to close the circular hole, and both are fixed by a stopper 24 (FIGS. 1 and 2). The see-through plate means a see-through plate body made of a resin transparent plate such as a transparent acrylic plate, a transparent glass plate, or the like.

  The water flow forming means 5 is a device for creating a horizontal water flow V in the container 15 by disposing a discharge port 55 in the water in which the water 7 is stored in the container 15 (FIGS. 2 and 4). ). The water flow forming means 5 forms a water flow V that slowly rotates the water in the container 15 in a spiral shape as shown in FIG. 3 in a plan view looking downward from the upper surface opening 10. The submersible pump 5 a may be a general-purpose pump or the like, but this embodiment employs the submersible pump 5 a as the water flow forming means 5. And the discharge cylinder part 54 which forms the discharge port 55 is distribute | arranged by the horizontal direction by the attachment to the inside of the container of the submersible pump 5a, and the discharge water flow PV from the discharge port 55 is the water in the container 15 by operation | movement of this submersible pump. Is set to form a horizontal water flow V. Specifically, a disk-shaped base 8 is fixed to one corner of the bottom plate portion 11 of the container body 1 and the bowl-shaped base 5b of the submersible pump 5a is fixed to the base 8 (FIGS. 2 and 3). ). The lower part of the submersible pump 5a is inserted into the upper part of the cradle 5b, and the submersible pump is fixed upright as shown in FIG. Here, the discharge cylinder portion 54 is disposed near the side plate portion 12 and in parallel with the side plate portion. The submersible pump 5a is mounted on the bottom plate portion 11 inside the container via the base 8 and the cradle 5b. When the submersible pump 5a is attached to the inside of the container and water is filled in the container 15 as described above, when the submersible pump 5a is operated, the discharge water flow PV from the discharge port 55 is horizontal in the plan view of FIG. A water flow V that swivels clockwise is produced.

  The submersible pump 5a is inserted into and fixed to the cradle while being locked to the upper inner collar of the cradle 5b having an open top surface (FIG. 4). Slit-like cutout windows 59 are formed at regular intervals in the circumferential direction of the standing lower portion of the cradle 5b. When the submersible pump 5 a is operated, the impeller 51 rotates, and the water 7 around the cradle 5 b out of the water 7 accumulated in the container 15 passes through the notch window 59 and is sucked to the inflow port 50. Then, the water 7 passes through the impeller 51 and is discharged from the discharge port 55 as a discharge water stream PV. The water 7 stretched in the container 15 by the discharged water flow PV creates a horizontal water flow V in FIG. 2, and rotates horizontally around the center of the container body 1 in the plan view as shown in FIG. A water flow V in the direction is formed. Of course, the clockwise rotation can also be made counterclockwise depending on the installation location of the submersible pump 5a.

  A cigarette plug 62 is fixed to the tip of the cord 61 extending from the drive motor 53 of the submersible pump 5a (FIG. 1). When the fish 8 captured by fishing is put in the container 15 filled with water and transported to the house by car, the power of the submersible pump 5a can be easily secured by inserting the cigarette plug 62 into the cigarette outlet of the car, The submersible pump 5a can be operated. Reference numeral 65 denotes a battery plug, which is a separate item connected to the cigarette plug adapter 63 by a cord 64. In the case of fishing, there are many cases that bring a reel winding battery (fishing battery). The submersible pump 5a can be operated by inserting the cigarette plug 62 into the adapter 63 and connecting the battery plug 65 to the reel winding battery. Reference numeral 52 denotes a casing of the submersible pump 5a, and reference numeral 57 denotes a main shaft.

The air supply means 3 is a device that feeds air into the water stored in the container body 1 to take in oxygen (FIGS. 1, 4, and 5). The fish 8 caught by collecting the water 7 in the container 15 is accommodated. However, if the dissolved oxygen consumed by the fish 8 is not supplied, the fish 8 is in an oxygen deficient state. The air supply means 3 sends air into the water and dissolves oxygen in the water 7.
Here, the air supply means 3 includes an intake port 311 for the outside air FA provided at the upper part of the container body 1 and a conduit 3a disposed from the intake port to the vicinity of the impeller 51 of the submersible pump 5a. The submersible pump 5a is shared and the impeller 51 of the submersible pump rotates, so that the outside air FA is sucked from the intake port 311 to the impeller 51 together with the water 7 around the submersible pump 5a. Configure as follows. 4 and 5, white arrows indicate the flow of outside air (air) FA sucked into the impeller 51 from the intake port 311. The outside air FA sucked into the impeller 51 together with water becomes bubbles Bu that are finely crushed by being stirred by the impeller 51, and flows out as fine bubbles Bu together with the discharge water flow PV from the discharge port 55. . From the discharge port 55, the air passing through the intake port 311, the conduit 3 a and the impeller 51 is finely crushed by the impeller 51 and injected into small bubbles Bu mixed with the discharge water flow PV. Since the small bubbles Bu have a large surface area in contact with the water 7, oxygen dissolves more rapidly into the water.

Each part of the air supply means 3 of this embodiment is explained in full detail. The intake 311 is provided in the chip component 31 (FIG. 5). The chip component 31 is a resin component in which a hole for the intake port 311 is provided in the upper lid portion 31c, and the upper lid portion is fixed and integrated on the upper surface of the cylindrical body 31b as shown in FIG. An inner flange 31a projects from the lower end of the cylindrical body 31b to form a small hole with a narrowed inner diameter of the cylinder, and the cylindrical connector 33 is inserted into the small hole from the housing chamber 15 side and integrated. The upper end portion of the connector is fixed to the chip component 31. The lower end portion of the connector 33 is connected and integrated with one end of the tube 32. The tube 32 hangs downward as shown in FIG. 2, and is connected and integrated with a cylindrical connector 34 whose other end is fixed to the base 8 (FIG. 4). Although the connector 33 and the connector 34 are simply illustrated as sleeves, actually, a known tube connector part is used.
On the other hand, the base 8 is provided with a vertical hole directly below the shaft center of the submersible pump 5a, and further with a horizontal hole extending from the base side wall 81 to the vertical hole. A through-hole 82 extending from the base 8 to the upper surface of the base 8 is formed (FIG. 4). The base end of the coupling tool 34 is inserted and fixed in the through hole 82 of the base side wall 81, and the distal end of the coupling tool is integrally connected to the other end of the tube 32. Further, the short pipe 37 is inserted and fixed in the vertical hole appearing on the upper surface of the base 8, and the upper end of the short pipe is set to be disposed near the impeller 51 of the submersible pump 5a as shown in FIG. The chip part 31 that forms the intake port 311 and the passage 312, the connector 33, the tube 32, the connector 34, the base 8 that forms the through hole 82, and the short pipe 37 constitute the conduit 3 a according to the present invention. Further, the submersible pump 5 a is added to the configuration of the air supply means 3. By rotating the impeller 51 of the submersible pump 5a, the outside air FA outside the container is sucked into the impeller 51 from the intake port 311 through the conduit 3a together with the water 7 around the submersible pump 5a. Here, the conduit 3a referred to in the present invention is not limited to a tube material such as a tube, but may be any member that forms a guide hole. Moreover, it may not be composed of a single tube or hose, but may be a composite body in which members and parts having guide holes are connected.
The air sucked into the impeller 51 together with the water 7 is finely crushed by mixing and stirring with the water 7, and then the discharged water flow PV from the discharge port 55 into the water in which the water 7 is stored in the container body 1. The air bubbles Bu are ejected as fine air bubbles Bu. The impeller 51 that sucks up the water 7 of the submersible pump 5 a also plays a role of sucking up the outside air FA that is conducted through the intake port 311 and the conduit 3 a, and the submersible pump is used as a power source of the air supply means 3. The power source of the air supply means 3 for sending air into the water may be an air compressor or the like. However, if the submersible pump 5a as the water flow forming means 5 is shared as shown in FIGS. 2 to 5, the apparatus cost can be reduced, and the overall capacity of the live fish transport container can be reduced, which is more preferable.

  The air venting tool 4 is integrated with the upper part of the container body 1 or the lid 2, and the upper part UA in the container 15 formed by covering the container body 1 storing water 7 with the lid 2, and the outside of the container This is an air escaping component or an air escaping portion having an opening 46 for conducting with the outside air FA (FIGS. 2 and 6). The air release tool 4 discharges the air corresponding to the pressure increase in the container 15 to the outside by the pressure increase caused by the air of the air supply means 3 fed into the container 15 while the container body 1 is covered with the cover 2. To do. The air venting tool 4 here is a separate body and is fixed and integrated with the lid 2 later, but can be integrally formed when the container body 1 and the lid 2 are molded. The air bleeding tool 4 may be one in which the opening 46 is simply formed in the upper part of the container body 1 or the lid body 2. However, the upper air UA in the container 15 formed by providing the through hole 45 in the lower part of the sealed hollow body 4a and providing the opening 46 in the upper part and covering the container main body 1 storing water with the cover body 2 is formed in the through hole. It is more preferable to use the air venting tool 4 that is connected to the outside air FA through the air chamber 47 in the sealed hollow body 4a and the opening 46. When transporting a live fish transport container by car, if the air vent 4 is provided with only the opening 46, the water 7 in the container 15 that has passed through the opening 46 is likely to spill into the vehicle interior and become dirty. This is because if the passage 45 and the air chamber 47 are obstructed, even if the water in the container 15 rippls due to running vibration, the water 7 in the container 15 does not easily spill into the vehicle interior.

In the present embodiment, a closed-bottomed cylinder 4b as shown in FIG. 6 is provided, and a through hole 45 is provided in the bottom part 40 which is the lower part, and a through hole 46a is provided in the upper cover part. And The top opening 46 of the bottomed cylindrical body is integrated by a lid with a perforated disk, and the air vent 4 is provided with a through hole 45 in the bottom 40. In addition to measures to prevent water spilling out of the container, the problem of bubbles appearing on the water surface 71 is solved. Seawater to be put in the container 15 is likely to foam due to vibration during vehicle travel. Even if the bubble 72 tries to reach the opening 46, it is blocked by the through hole 45 and the air chamber 47 existing in front of the bubble 72, and only the air corresponding to the pressure increase in the container 15 is smoothly discharged from the opening 46 to the outside of the container. Here, as shown in FIG. 6, the length t ₁ of the through hole 45 formed in the bottom portion 40 is set longer than the length t _{2 of} the through hole 46 a formed in the lid portion 42. By lengthening the through hole 46a, the water 7 in the container 15 vibrates and shakes, and it is difficult to try to pass through the through hole 46a. Here, the length of the through hole 46a is ensured to 10 mm (preferable range is 10 to 50 mm). If it exceeds 50 mm, the air bleeding tool becomes too large. Foam 72 by seawater bubbling in container 15 is also crushed while passing through the long period t ₁ of the through hole 46a. While passing through the long through holes 46a, the bubbles 72 are crushed and the bubbles 72 disappear. Further, even if water passes through the through hole 46 a and further rises in the air chamber 47, it is dropped downward by the return of the lid portion 42. Only the air corresponding to the pressure rise in the container 15 is smoothly discharged out of the container through the through hole 46a as shown by the arrow in the figure.

The air bleeder 4 can be a different product as shown in FIG. The same reference numerals as those in FIG. 6 denote the same or corresponding parts, and the description thereof is omitted. The air bleeding tool 4 of FIG. 7 (a) has a mortar shape on the inner surface from the cylinder portion 41 to the bottom portion 40 of FIG. 6, and a through hole 45 is provided at the bottom. Even if water enters the air chamber 47 in the cylinder portion 41, the water drops by gravity and is successfully returned to the inside 15 of the container. In FIG. 7 (b), the inner surface of the bottom 40 is conical and a through hole 45 is provided at the lower end. The arrows in FIGS. 7A and 7B indicate a flow in which even if the water 7 in the container 15 enters the air chamber 47, the water flows down and returns to the container 15 through the through hole 45.
In the air release tool 4 of FIG. 7 (b), the lid portion 42 is not provided, and the upper surface of the cylinder portion is opened as it is to be an opening 46. Even if a part of the water shaken by the running vibration of the vehicle passes through the through hole 46a and further rises in the air chamber 47, it is dropped downward by the return of the lid portion 42, as shown in FIGS. Unlike the tool 4, there is a risk that water will spill out as long as the lid portion 42 is not returned. However, this is sufficient when the distance from the water surface to the bottom 40 and the height of the air chamber 47 can be sufficiently secured and water does not spill out.

Reference symbol HS denotes a water discharge hose in the container 15. Hose HS has a hose hole HS ₁ to be fitted to the discharge tube portion 54 of the water pump 5a. After the hose HS is fitted and connected to the discharge cylinder portion 54 and the tip of the hose is taken out of the container A, the water 7 stretched inside the container 15 can be easily poured out of the container by operating the submersible pump 5a.

The live fish transport container configured as described above has the water flow forming means 5 that creates the horizontal water flow V in the container 15 by disposing the discharge port 55 in the water stored in the container 15. Therefore, the live fish 8 captured by fishing etc. and accommodated in the container 15 can be kept healthy. Many of the fish 8 have developed a running ability against the flow. Rather than simply filling water in the container 15, creating a horizontal water flow V that matches the swimming direction of the fish 8 stimulates the fish 8 and makes it healthy. By creating a horizontal water flow V as shown in FIGS. 2 and 3 in the container 15, the live fish 8 having positive running ability can swim vigorously with the head facing upstream. Incidentally, the water flow V in the container 15 produced by a conventional air pump, air disperser, etc. causes convection in the vertical direction, and the fish 8 is difficult to swim, but weakens the fish 8 on the contrary. The transport container for live fish of the present invention can lighten the burden on the fish 8 by making the water flow V substantially horizontal, does not accumulate stress, and regains the energy of the fish 8 that was not healthy. It can be transported alive to the ground.
In addition to the water flow forming means 5, the present live fish transport container includes an air supply means 3, and the air supply means 3 can replenish dissolved oxygen consumed by the live fish in water. The increase in internal pressure in the container 15 by the air supply means 3 is discharged out of the container by the air venting tool 4.

  The air vent 4 is provided with a through hole 45 in the lower part of the sealed hollow body 4a and an opening 46 in the upper part, and the upper air UA in the container 15 and the outside air FA outside the container are connected to the through hole 45 and the sealed hollow body 4a. By the structure that conducts through the air chamber 47 in the body 4a and further through the opening 46, it is possible to reliably prevent water from spilling out of the container. The water in the container 15 sways and spills out of the container due to vibration while the vehicle is running. However, the air supply means 3 supplies air to the inside 15 of the container by limiting the conduction point between the inside 15 of the container and the outside of the container to a passage passing through the through hole 45 of the air vent 4, the air chamber 47, and the opening 46. While ensuring air bleed to discharge the increase in air pressure accompanying supply, water 7 in the container 15 is blocked by the through hole 45, and the height of the air chamber 47 becomes a barrier, so that the water 7 is discharged outside the container. Can prevent spillage.

Further, in the air bleeding tool 4 of the present embodiment, the bottomed tubular body 4b with the lid is provided with the through hole 45 in the bottom part 40 as the lower part and the through hole 46a in the lid part 42 as the upper part. While preventing the water of the inner 15 from leaking out of the container, the air bleeding function can be more reliably exhibited. Since the live fish carrying container provided with the air supply means 3 supplies air from the outside to the inside 15 of the container, the pressure in the inside 15 of the container increases. An open / close valve or float type with an operating part may not be opened without falling after closing. Then, despite the fact that the air cannot be removed, the external air FA continues to be supplied and the pressure in the container 15 increases, so that the water in the container body 1 and the lid body 2 leak from the threaded portion. There is a risk. Alternatively, the pressure in the container 15 increases, and the outside air FA from the air supply means 3 cannot be supplied, and the fish in the container 15 may be killed.
The air vent 4 having the bottomed cylinder body 4b with the through hole 45 in the bottom portion 40 and the through hole 46a in the lid portion 42 does not have an operating part such as an on-off valve or a float type. Trouble does not occur. In addition, because of the structure, even if the water in the container 15 jumps due to the shaking of the vehicle and the water 7 that has passed through the through hole 45 is generated, it is extremely difficult to raise the air chamber 47. Thus, it is almost impossible to get out of the container through the through hole 46a. In particular, the length t ₁ of the through hole 45 is set to be longer than the length t _{2 of} the through hole 46 a, so that the splashed water in the container 15 is less likely to enter due to the shaking of the vehicle. ing. This also means that when the bubbles 72 due to the bubbling of seawater enter the through holes 45, the bubbles 72 are liable to be crushed. Therefore, the trouble caused by the bubbles 72 can be solved, and the air bleeding tool 4 is more excellent.

  And the water flow formation means 5 is the submersible pump 5a, and the discharge cylinder part 54 which forms the discharge port 55 is arranged in the horizontal direction by mounting the submersible pump 5a inside the container, and the discharge port 55 by the operation of the submersible pump 5a. When the discharge water flow PV from the water creates a horizontal water flow V in the water 7 in the container 15, the horizontal water flow V can be easily formed. Moreover, in the present invention, the power source of the air supply means 3 is carried by the submersible pump 5a.

  Air having an intake port 311 for the outside air FA provided in the upper part of the container body 1 and a conduit 3a disposed from the intake port to the vicinity of the impeller 51 of the submersible pump 5a, and sharing the submersible pump 5a. The supply means 3 is adopted. When the impeller 51 of the submersible pump 5a rotates, it is an air supply means in which the outside air FA is sucked into the impeller through the intake port 311 and the conduit 3a together with the water 7 around the submersible pump 5a.

By contributing the power source of the water flow forming means 5 and the air supply means 3 to one submersible pump 5a, it contributes to downsizing and cost reduction of the live fish transport container. The structure of the air supply means 3 can be simplified. By sharing the submersible pump 5a, it is only necessary to add the conduit 3a disposed from the intake port 311 to the vicinity of the impeller 51 of the submersible pump 5a as the air supply means 3. The submersible pump 5a plays the role of one unit of the water flow forming unit 5 and the air supply unit 3. In addition, if the impeller 51 of the submersible pump 5a is turned after filling the container 15 with water, the discharge water flow PV flows out from the discharge port 55 to the container 15 and the horizontal water flow V into the container 15 V At the same time, fine bubbles Bu are ejected from the discharge port 55 by the air supply means 3. When the submersible pump 5a rotates, the outside air FA around the intake port 311 is sucked together with water from the intake port through the conduit 3a into the impeller 51. Furthermore, the sucked outside air FA is stirred together with the water 7 sucked by the impeller 51 and crushed finely. From the discharge port 55, it becomes the micro bubble Bu and is ejected with the discharge water flow PV. Even if there is no air disperser required in Patent Document 2 etc., the impeller 51 of the submersible pump 5a adopted as a power source has a configuration that also serves as an air disperser. It is a proper container for live fish. The impeller 51 of the submersible pump 5a mixes the water 7 and the outside air FA sucked from the intake port 311 to form fine bubbles Bu particles, which are sent into the water from the discharge cylinder portion 54 and circulate in the container 15. Dissolved oxygen is fully supplied to the water 7 in the container 15. The submersible pump 5a also serves as an air disperser in addition to the air pump, and plays a role of three units, making it an innovative live fish transport container.
Furthermore, it is not necessary to provide a pump storage chamber in which the air pump is isolated and installed, and an effective space for storing live fish 8 occupying the entire container becomes large.

  The live fish container according to the present invention is mainly intended to be transported to a destination such as a home over about 6 hours by car while catching fish or fry released by fishing. When the submersible pump 5a is operated, electricity can be supplied from a cigarette outlet or a battery for fishing, and the transport container for live fish is excellent in convenience. As the container A, a capacity of about 100 to 200 liters is adopted for passenger cars (including wagon cars and wagon cars), and a capacity of about 1000 liters is adopted for trucks (light four trucks, ordinary trucks). Is done. A 1000 liter container for live fish can be used in a 1 ton truck if it is filled with, for example, about 800 liters of water, and is suitable for the discharge of fry of sweetfish and trout.

And since the observation window 2b is provided, the inside 15 of the container can be checked at any time, and the live fish 8 caught in peace can be taken home. It can be safely transported to the destination even when fry is released.
Moreover, by providing the hose HS shown in FIG. 1, the water 7 in the container 15 can be easily extracted. For example, after putting fish 8 captured by fishing in a live fish transport container and taking it home, if water 7 is in container A, it cannot be removed from the car alone, but it can be easily removed by using hose HS. Can do. If one of the hoses HS is inserted into the discharge cylinder portion 54 of the submersible pump 5a and the other is taken out of the vehicle, and then the submersible pump 5a is operated, the required amount of water 7 in the container 15 can be extracted without difficulty. If you take the live fish container from the car when it gets lighter, you won't have any trouble.
As described above, the live fish transport container of the present invention has a simple structure and the movable part is only the submersible pump 5a while exhibiting the many excellent effects described above, so that there are few failures and low cost. It is extremely beneficial to contribute.
