    Fish sucking arrangement for removing dead fish in a fish tank
    FIELD OF THE INVENTION
    This specification relates to a fish sucking arrangement for removing dead fish in a fish tank, the fish sucking arrangement comprising a suction inlet connected to a dead fish outlet and flow means for establishing a flow in the channel between the sucking inlet and dead fish outlet to discharge dead fish, the fish sucking arrangement is adapted to be mounted on an inner end or outer end of a partition.
    The fish sucking arrangement can work with a fish breeding facility with a central tank, which is at least partially surrounded by one or more fishing tanks, where at least one or more fishing tanks has an inner wall with an inner wall surface and an outer wall with an outer wall surface, said fish tank having a fish tank width as the distance between the inner wall surface and the outer wall surface along the extension (azimuth, arc) of the at least one fishing tank; the fish breeding system further comprises at least one partition with a partition width between an inner end and an outer end of the partition and configured to span between the inner wall surface and the outer wall surface; wherein the partition width is greater than the fish tank width.
    BACKGROUND OF THE INVENTION
    Managing fish at various stages during growth in a managed or industrial production framework is an important part of the aquaculture industry.
    Prior to this description, fish farming facilities, which have a central tank, are described in the patent literature.
    For example, DK 2014 70781 A1 describes an arrangement of circular, concentric fish tanks divided by a removable compartment wall or separator. The compartment wall has a central portion of fixed width which, on the side, has pivotal parts to close off against the walls of the fish tank to prevent fish from escaping from one compartment to another.
    DK 2019 00109 U1
    The compartment wall is supported by a bar which is adjustable by means of a telescope type arrangement to “automatically” adjust the width.
    In practice, however, numerous problems remain in securing the separation of the fish tank divisions due to complexity. There is also a need to improve how dead and / or live fish are handled, and to provide an alternative solution to existing systems.
    Flexibility of the size of fish tanks and sampling of fish - either dead or alive - are areas that generally need improvements in industrial aquaculture.
    It is an object of the present invention to overcome one or more of the aforementioned problems and to generally simplify the departmental walls so as to improve functionality in practice and to improve flexibility while taking into account the handling of dead fish or live fish.
    Description
    Fish suction arrangement for removing dead fish in a fish tank, the fish suction arrangement includes a suction inlet connected to a dead fish outlet and flow means for establishing a flow in the channel between the suction inlet and dead fish outlet for discharging dead fish, the fish suction arrangement is adapted to be mounted on an inner end or outer end of a partition.
    The fish-sucking arrangement or dead-fish-gathering arrangement, which will be described herein, can be seen in the context of a fish-breeding plant with a central tank, which is at least partially surrounded by one or more fishing tanks. At least one of the one or more fishing tanks has an inner wall with an inner wall surface and an outer wall with an outer wall surface. Said fish tank has a fish tank width as a distance between the inner wall surface and the outer wall surface along the extension (azimuth, arc) of the at least one fishing tank.
    The central tank can be configured with a water treatment plant according to special needs. The water treatment plant can be a biofilter type plant. A subject
    DK 2019 00109 U1 man will recognize the need to provide the necessary lines, pipes, connections, flow applicators and flows to create a fish farming facility adapted to particular types of fish.
    The fish farming facility may further comprise at least one partition with a partition width between an inner end and an outer end of the partition. The partition is configured to span between the inner wall surface and the outer wall surface; wherein the partition width is greater than the fish tank width.
    It is to be understood that the width of the partition may be at least 5% greater than the fish tank width.
    In another embodiment, the partition wall may be 15% larger than the fish tank width, as this will increase the angle between the partition wall and the key of the central tank.
    One effect of having a partition width greater than the fish tank width is that the fish tank may be built or constructed with a varying width along a trajectory. This will reduce the precision needed when the fish tank is being built and thus the construction cost will be reduced.
    A person skilled in the art will usually create a simple or symmetrical construction. However, in practice it has proved very difficult to construct a fishing tank with a constant fish tank width. Or the width may vary over time. Here, read constantly as within the permissible margin of error. If the fish tank has a section where the width of the fish tank is outside the allowable margin of error, then the partition wall would not be able to move into this section and thus the fish tank would have partition dead zones, which would limit its applicability.
    The above problem is removed by increasing the partition width beyond the fish tank width, as the fish tank must not have compartments where the partition wall is unable to move into the previously mentioned compartment due to incompatible dimensions.
    DK 2019 00109 U1
    Another effect of having a partition width greater than the fish tank width is that the partition wall will always have an angle to the tangent of the central tank at the interaction between the partition wall and the central tank, which always deviates from 90 degrees.
    The angle will have an impact on the collection of dead fish. The dead fish will be drawn by the current in the fish tank towards the partition, and because of the angle relative to the tangent of the central tank, the dead fish will move towards the same area from which the dead fish can be easily collected.
    In one aspect of the invention, the outer wall has outer wall engaging means for engaging with outer separation engaging means for moving and / or positioning the outer end of the partition.
    Similarly, the inner wall has retractable engagement means for engaging with internal separation engagement means for moving and / or positioning the inner end of the partition.
    By having a movable partition, the fish farming facility can be set to have the most optimal conditions for the fish throughout their entire life cycle.
    In one aspect of the invention, the partition may comprise at least one fish suction arrangement having a suction inlet located at a lower end of the partition. The at least one fishing suction arrangement may be disposed towards the inner end, outer end or both ends of the partition.
    One embodiment of a fishing suction arrangement comprises a suction inlet connected to a dead fish outlet with a duct. The fish sucking arrangement further comprises flow means for establishing a flow in the duct between the suction inlet to the dead fish outlet to discharge dead fish.
    The fishing suction arrangement may be adapted to be mounted on an inner end or outer end of a partition.
    DK 2019 00109 U1
    Dead fish will be pulled by the flow until it reaches a partition, where it can be forced toward either end of the partition, depending on the angle of the partition with an inner and outer wall of a fish tank. Thus, the fish sucking arrangement can effectively collect the dead fish by being connected to the partition.
    If the partition has a width greater than the fish tank width, then the fish will gather at the end of the partition which forms a pointed angle with an inner or outer wall of a fish tank.
    The fishing suction arrangement may act independently of the angle of the partition with an inner / outer wall of a fishing tank.
    The suction inlet is located at the bottom of a fish tank containing live and dead fish, while the dead fish outlet is located outside the fish tank for removal of dead fish.
    The suction inlet may comprise a suction inlet port which can be opened and closed, thereby controlling the fishing suction arrangement.
    The suction inlet port can be controlled by a suction inlet handle.
    The suction inlet may be cone-shaped, thereby enabling the fish suction arrangement to collect from a larger area.
    Dead fish outlet may be in connection with a dead fish reservoir, which can be emptied regularly.
    The dead fish outlet may be in connection with a carrier that can transport the dead fish further away from the fish tank.
    The dead fish can be transported to a bioreactor or rotten tank.
    DK 2019 00109 U1
    In one aspect, dead fish outlet includes means for changing dead fish outlet direction. The person skilled in the art will know how to make the organs to change the dead fish outlet direction.
    The effect of a variable direction of the dead fish outlet is that the direction of the suction inlet and the direction of the dead fish outlet are decoupled, which ensures that the partition can change angle with an inner and / or outer wall of a wall in a fish tank. Thereby, the dead fish outlet may be associated with means for removing dead fish, such as a reservoir for dead fish or a conveyor, regardless of the direction of the suction inlet and / or the angle of the partition.
    The flow means for establishing a flow of dead fish in the duct from the suction inlet to the dead fish outlet to discharge dead fish may be one or more injectors or nozzles that inject air, thereby establishing an uplift with air and a flow from the suction inlet to dead fish outlet. This allows the fish inlet to collect dead fish as the fish will be sucked towards the fish inlet, from where they will be forced through the channel and out of the dead fish outlet.
    The flow means for establishing a flow of dead fish may be established with a pump which creates a flow from the fish suck inlet to the dead fish outlet. This allows the fish inlet to collect dead fish as the fish will be sucked towards the fish inlet, from where they will be forced through the channel and out of the dead fish outlet.
    As an example, a method for removing dead fish from a fish tank may be performed by one or more actions of:
    - An act of creating a flow in the duct from the suction inlet to the dead fish outlet to discharge dead fish;
    - An act of sucking from the suction inlet.
    The flow will create the suction in front of the suction inlet.
    There may also be an act of collecting dead fish outside the fish tank.
    DK 2019 00109 U1
    The method may be carried out by an at least partially autonomous computer system controlling the fish-sucking arrangement.
    In one aspect of the invention, one or more partitions may be capable of rotating more than 360 degrees around the fish tank.
    The flexibility of the fish farming facility is greatly increased by having partitions that are able to move freely around the fish tank.
    This is especially true when there is more than one partition in the fish tank, as they can delineate spaces of any size.
    Depending on the angle between the partition wall and the tangent of the central tank by the interaction between the partition wall and the central tank, the dead fish may be collected by the fish suction arrangement at the inner or outer end of the partition.
    It may be advantageous to change the angle, and consequently, in one embodiment, a fishing suction arrangement may be located at each end of the partition.
    In one aspect of the invention, the fish withdrawal arrangement may have a withdrawal plate configured to span the partition width, and it may be configured to move from the bottom of the fish tank up to the top.
    The upward movement of the withdrawal plate will direct the fish to move towards the withdrawal vessel. Thus, the fish are easily removed.
    The outlet plate may be guided in a guiding device and powered or driven by a motor in a drive system.
    An embodiment of a fish sampling arrangement for sampling or collecting live fish from a fish tank, the fish sampling arrangement includes a fish sampling plate which is
    Suitable for forming a closed space with at least two partitions in which at least one of the partitions is movable, the fish withdrawal arrangement comprises additional means for moving the withdrawal plate.
    It is easier to remove fish when the fish density is high, but when fish is removed from the fish tank, the fish density is reduced. The decrease in fish density can be counteracted by moving the withdrawal plate from the bottom of the fish tank to the top, thereby reducing the size of the space.
    The live fish can be collected manually from the fish tank or with a fish pump or through a port. The person skilled in the art will know how the fish can be collected from the fish tank.
    The outlet plate may be of any shape as long as the outlet plate is capable of forming the enclosed space with the movable walls and one or more side walls of a fishing tank. Thus, the enclosed space can have any shape.
    Each movable wall may be perpendicular to an inner and / or outer wall surface of the fish tank.
    Each movable wall can form an angle with a wall surface of the fishing tank, which angle is less than 90 degrees.
    The outlet plate may be attached to a guide, which may be powered by a motor to move the outlet plate along the guide.
    The withdrawal plate may be connected to a crane system such that the withdrawal plate can be completely removed from the fish tank in situations where there is no live fish to be removed from the fish tank.
    The crane system can lower the withdrawal plate to the bottom of the fish tank when live fish must be removed from the fish tank.
    DK 2019 00109 U1
    This may be followed by steps of moving the movable walls adjacent to the fish withdrawal plate, thereby forming the enclosed space.
    The crane system can subsequently lift the withdrawal plate, thereby reducing the space.
    After the fish tank has been emptied, the crane system can lift the withdrawal plate out of the fish tank.
    In one aspect of the invention, the fish farming facility further comprises a fish take-out container in connection with the fish take-off arrangement in the fish tank via a take-out port in the outer or inner wall.
    In one embodiment, the fish withdrawal arrangement may further comprise a fish withdrawal container.
    An embodiment of a fish withdrawal vessel for withdrawing fish from a fish tank, the fish withdrawal vessel being located on an inner wall or outer wall of a fishing tank and comprising a withdrawal port for controlling a connection with a fish tank and a discharge point at a lower portion of the fish withdrawal vessel. collection of live fish.
    The outlet port can be opened or closed by rotating engagement with an outlet port handle.
    The withdrawal port may comprise a damper capable of separating the interior of the fish withdrawal container from the interior of a fishing tank by sliding downward. The damper can be moved by means of a drive or moved manually.
    The discharge point can be placed at the bottom of the withdrawal container, thereby allowing the fish withdrawal container to be completely emptied if the withdrawal port is closed.
    The fish take-out container may be in connection with the fish take-out arrangement, so that the collection efficiency for live fish is increased, as the fish take-off arrangement will force the fish together and thus towards and through the fish take-out container.
    DK 2019 00109 U1
    The outlet plate can be moved up to the bottom of the outlet port, the enclosed space being thereby at its minimum size.
    The damper may comprise a damper bore at an upper part of the damper, such that when the outlet port is closed, the outlet plate can be moved up to the bottom of the damper bore, whereby the size of the closed space can be further reduced.
    The remaining live fish can then be manually swept into the enclosed space.
    The damper bore can subsequently be closed or blocked so that the fish take-out container can be emptied, thereby collecting the remaining fish.
    The damper bore can be closed or blocked with plugs or a plate. The person skilled in the art will know how to make the plug or plate so that no water will flow through the damper bore.
    In one aspect of the invention, the outlet container may comprise flow means for generating a flow through the outlet port and into the fish tank.
    This will further cause the fish to move from the fish tank towards the withdrawal port.
    Furthermore, the amount of dead fish or sediment moving from the fish tank through the withdrawal port is reduced as the water flow is in the opposite direction.
    In one aspect of the invention, the fish tank may have at least two partitions.
    By having at least two partitions, the fish farm can divide the fish tank into smaller, adjustable compartments. The advantage of having these adjustable spaces is that the space required per fish increases as a function of the size of the fish. Thus, it is possible to further optimize the plant according to growth stages, type, etc. during fish farming.
    DK 2019 00109 U1
    In one aspect of the invention, the fish farming facility may have a controller configured to move and position the respective outer and inner ends of one or more partitions as a function of predetermined actions.
    The effect of having a control unit to move the partitions as a function of predetermined actions is that the need for human interaction decreases, which will lead to a cost reduction.
    The method of extracting fish from a fish tank in a fish farming facility may include, for example, the step of placing an end of at least one partition adjacent a side of an open outlet port connecting the fish tank to an outlet tank.
    The above step will be followed by a step of lifting a socket plate to near the bottom of the socket port.
    The above step will be followed by a step of creating a flow through the outlet port and into the fish tank.
    The above step will be followed by a step of closing the outlet port.
    The method of extracting fish from a fish tank in a fish farming facility may further comprise the step of sucking from at least one suction inlet.
    An embodiment of a method for extracting fish from a fish tank in a fish farming facility may include the actions of:
    - An act of placing may be performed by placing an end of at least two partitions near one side of an open outlet port connecting the fish tank to an outlet container.
    This will increase fish density, which may force fish to swim through the withdrawal port into the withdrawal bin from which the fish can be collected.
    DK 2019 00109 U1
    - An act of lifting can be performed by lifting a socket plate to near the bottom of the socket port.
    This can further force fish to swim through the withdrawal port and into the withdrawal bin from which the fish can be collected.
    - An act of closing the outlet port can be performed so that the outlet container can be completely emptied of water and fish.
    It can be time consuming to get all the fish swimming through the withdrawal gate. In addition, the above actions can cause the fish to panic or stress. The panic or stressed fish can empty their guts, resulting in unclear water, making it difficult to determine if all the fish have been collected.
    The unclear water can be counteracted by further acts of sliding a damper into the outlet port, said damper having a damper bore in part of the damper.
    The damper blocks the lower part of the outlet port so that an act of lifting the outlet plate to near the bottom of the damper bore can be performed. The depth down to the withdrawal plate is thereby reduced, so that a person can, at sight, inspect the number of remaining fish in the fish tank.
    This can be followed by an act of forcing fish through the damper bore and into the receptacle. This can be done by a person sweeping the fish towards the exit port.
    When there are no more live fish in the fish tank, an act of closing the damper can be performed, thereby closing the withdrawal port. This can be done by blocking the damper bore. The person skilled in the art will know how to properly block the damper bore.
    Eventually, an action can be performed to empty the withdrawal vessel, and the remaining fish will then be collected.
    DK 2019 00109 U1
    The fish farming facility has bodies adapted to carry out the procedure of extracting fish from a fish tank from a fish farming facility.
    A computer program may include instructions to cause the fish farming facility to perform the procedure of extracting fish from a fish tank of a fish farming facility.
    A computer-readable medium may have the computer program stored on it.

    FIG. 1 illustrates an outline of a circular fish breeding system 100 having a central tank 110 which is surrounded by a fishing tank 120. The fishing tank 120 has an inner wall 132 with an inner wall surface 130 and an outer wall 137 with an outer wall surface 135. The fish breeding system 100 has a fish tank width 140 due to the circular shape.
    The fish tank 120 has a partition 200 with an inner end 230 at the inner wall 132 and an outer end 235 at the outer wall 137. Only a single partition 200 is indicated in the figure, but the fish farming facility 100 may have more than one.
    The water flow direction 180 is counterclockwise.
    FIG. 2 illustrates an outline of one embodiment of a circular fish farming facility 100 having a central tank 110 surrounded by one fishing tank 120. The fishing tank 120 has an inner wall 132 with an inner wall surface 130 and an outer wall 137 with an outer wall surface 135. The fish farming facility 100 has one fish tank width 140 due to the circular shape.
    The fishing tank 120 has one partition 200 with an inner end 230 at the inner wall 132 and an outer end 235 at the outer wall 137. Only a single partition 200 is indicated in the figure, but the fish farming system 100 may have more than one.
    DK 2019 00109 U1
    The water flow direction 180 is counterclockwise. The fishing suction arrangement 260 is in this embodiment located at the inner end 230 and the outer end 235 of the partition 200.
    FIG. 3 illustrates an outline of another embodiment of a fish farming facility 100 having a central tank 110 surrounded by two fishing tanks 120 of different radii. The inner fish tank 120 has an inner wall 132 with an inner wall surface 130 and an outer wall 137 with an outer wall surface 135. The fish farming system 100 has an inner fish tank width 140 due to the circular shape.
    The inner fish tank 120 has a partition 200 with an inner end 230 at the inner wall 132 and an outer end 235 at the outer wall 137. The inner fish tank 120 has two partitions 200, but the inner fish tank 120 can have any number of of partitions 200.
    There is no significant difference in the description of the figure between the inner fishing tank 120 in FIG. 3 and the fish tank 120 in FIG. 2nd
    The outer fishing tank 120 of FIG. 3 also functions exactly like the fish tank 120 in FIG. 2. The inner fish tank 120, from the perspective of the outer fish tank 120, can be seen as a central tank 110.
    One skilled in the art will recognize that adding more fishing tanks 120 to the fish farming facility 100 will not change the general working principle of the invention.
    FIG. 4 illustrates an outline of another embodiment of the fish farming system 100 having a circular central tank 110 and a fish tank 120 with an inner wall 132 having an inner wall surface 130 and an elliptical outer wall 137 with an outer wall surface 135.
    Due to the elliptical outer wall 137, the fish tank has half a small axis and half a large axis along the two dotted lines.
    DK 2019 00109 U1
    Those skilled in the art will know that the fish tank width 140 is the distance between the inner wall 132 and the outer wall 137 along the half-major axis, as those skilled in the art will understand that it is essential that the partition 200 be able to move around the central tank 110.
    The embodiment has two partitions 200; each partition 200 has an inner end 230 near the inner wall 132 and an outer end 235 near the outer wall 137.
    The central portion 110 may also be an ellipse.

    The fish suction arrangement 260 has a suction inlet handle 278 which controls the vertical position of the suction inlet port 275. The fish suction arrangement 260 is closed when the suction inlet port 275 blocks the suction inlet 270.
    The flow through the fish suction arrangement 260 is further created and controlled by one or more injectors 290 or nozzles. The nozzles may be connected to an air pump or compressor so that the air will form an upward lift and thus suction of water and dead fish.
    For further description of the fishing suction arrangement 260, see FIG. 14th
    FIG. 6 illustrates a detailed sectional view from the side of the fish farming facility 100 in a fish take-off position.
    The fish farming facility 100 has a central tank 110 which is surrounded by a fish tank 120 (partially shown). The fishing tank 120 has an inner wall 130 with an inner wall surface 132 and an outer wall 137 with an outer wall surface 135. The fishing tank 120 further has a bottom 160 and a top 165.
    A partition 200 spans the fish tank 120 from the inner wall 132 to the outer wall 137. The partition 200 has an inner end 230 with inner separation engaging means.

    At the lower end 280 of the separator, near the inner wall 132, the partition 200 has a fishing suction arrangement 260 with a suction inlet 270 for suction.
    FIG. 6 further describes a fish take-off arrangement 300 having a take-out plate 310 in the fish tank 120 and a take-out container 320 attached to the outer wall 137 on the opposite side of the outer wall surface 135. The connection between the take-off container 320 and the fish tank 120 is controlled in this embodiment by the take-out handle 335. , which can open or close an outlet port 330 (not shown).
    In other embodiments, the outlet port 330 may be controlled by other means.
    The outlet plate 310 is shown in an upper position. However, at the beginning of the withdrawal of fish, the withdrawal plate 310 will be at the bottom 160, from which it begins to move towards the top 165 of the fish tank 120.
    In order for the fish take-off arrangement 300 to work advantageously, the fish tank 120 needs another partition 200 or an equivalent obstacle which the fish cannot circumvent, otherwise it would be more difficult to guide the fish to move through the take-off port 330. See fig. 10 - 11.
    FIG. 7 illustrates a partition 200 having a partition width 240 and a lower end 280. The left side of partition 200 is shown with inner and outer separation engagement means 250, 255 for engaging a wall in a fish tank 120. The right side of partition 200 has also engaging means, but the engaging means are not shown.
    The embodiment has engaging means at the top and bottom of the partition 200, but the invention is not limited to this particular embodiment. The invention may have engagement means positioned differently and it may have a different number of engagement means.
    DK 2019 00109 U1
    The right side of partition 200 has a fishing suction arrangement 260 with a suction inlet 270 located at the lower end 280 of the partition. The flow through the fish suction arrangement is provided with one or more injectors 290 or nozzles which create an uplift with air.
    FIG. 8 illustrates the engagement between a partition 200 and an outer wall 137. An engagement between a partition 200 and an inner wall 132 would be the same. The figure shows an outer end 235 of a partition 200 having outer separation engagement means 255 at the top and bottom of the partition wall 200 for engagement with engagement means 155 from the outer wall of the outer wall surface 135 of the outer wall 137.
    FIG. 9 illustrates the inner and outer engagement members 250, 255 from a partition 200 in a side view. The inner and outer engagement members 250, 255 are rotatably engaged with the inner and outer ends 230, 235 of the partition 200. This allows the control unit 400 to change the angle between the central tank 132 and the partition 200.
    Further, if the inner and outer engagement members 250, 255 were not rotatably engaged with the partition 200, then it would further impose some serious restrictions on the fish breeding system 100, as both of the inner and outer walls 132, 137 must be complete circles.
    FIG. 10 illustrates an intermediate position of the fish withdrawals.
    The partitions 200 are located close together and they are both in contact with the outlet plate 310 which is halfway between the bottom 180 and the lower part of the outlet port 330.
    FIG. 11 illustrates the final position of the fish withdrawal arrangement.
    The partitions 200 are located close together, and they are both in contact with the outlet plate 310 located at the outlet port 330. The outlet port 330 is not shown in the figure because the outlet port handle 335 has rotatably moved the outlet port 330 upwards. The invention is not limited to how the outlet port 330 is opened and closed.

    FIG. 12 illustrates an embodiment of the receptacle 320 attached to the outer wall 137 of the fish tank 120.
    FIG. 13 illustrates the outlet container 320 as seen from inside the fishing tank 120. the outlet container 320 is located under an engagement means and the outlet port 330 is open.
    FIG. 14A illustrates only the fishing suction arrangement 260, and FIG. 14B illustrates the fishing suction arrangement 260 attached to a partition 200.
    The fish suction arrangement 260 has a suction inlet handle 278 which controls the vertical position of the suction inlet port 275. The fish suction arrangement 260 is closed when the suction inlet port 275 blocks the suction inlet 270.
    Furthermore, the flow through the fish suction arrangement 260 is created and controlled with the injectors 290 (not shown).
    FIG. 15 illustrates a method 500 for extracting fish from a fish tank 120 from a fish farming facility 100, the method 500 comprising acts of:
    - The act of placing 510 at one end of at least one partition 200 near one side of an open outlet port 330 connecting the fish tank 120 to an outlet container 320 (see Fig. 6).
    - The act of lifting the 520 outlet plate 310 to near the bottom of the outlet port 330 (see Fig. 10).
    - The act of creating 530 a flow 340 through the outlet port 330 and into the fish tank 120.
    - The act of closing the 540 outlet port 330.
    - The act of sucking 550 from at least one suction inlet 270.

    FIG. 16 illustrates an open outlet receptacle 320 comprising an outlet port 330 having a damper 360 with two damper bores 365.
    The outlet port 330 is open, and the receptacle 320 is thus in connection with a fish withdrawal arrangement 300 comprising a withdrawal plate 310 between two partitions 200.
    The withdrawal plate 310 is located at the bottom of the open withdrawal port 330, and live fish trapped in the fish withdrawal arrangement 300 can swim through the open withdrawal port 330 and into the withdrawal vessel 320.
    The live fish can then be collected through a hole in the bottom of the receptacle 320.
    In some cases, not all fish swim by themselves through withdrawal port 320. In such a case, a person can manually push the fish through the withdrawal port 320, but this can be troublesome as the fish still have plenty of room.
    The fish will typically be further stressed, which results in them emptying their bowels. This will cause the water to become opaque, making it difficult for the person to determine whether all living fish have been pushed through the withdrawal port.
    In this case, the outlet port 320 can be closed by forcing the damper 360 downwards, see fig. 17th
    FIG. 17 illustrates a closed outlet container 320 which comprises an outlet port 330 having a damper 360 with two damper bores 365.
    The outlet port 330 and thus the receptacle 320 are still in connection with a fish withdrawal arrangement 300 comprising a withdrawal plate 310 between two partitions 200, due to the two damper bores 365.
    DK 2019 00109 U1
    The outlet plate 310 can then be lifted using lifting means (not shown) to the bottom of the two damper bores 365.
    The additional lifting of the withdrawal plate 310 will limit the possible movement of the 5 fish and make it easier to spot the fish as they cannot hide in the opaque water so that a person can easily spot and push the living fish through one of the damper bores 365.
    The damper bores 365 can subsequently be closed so that the receptacle 320 can be completely emptied. Thereby the remaining fish are collected.
    The damper bores 365 can be closed with plugs or a plate.
    The fish withdrawal arrangement 300 shown in FIG. 10-13 may have a damper 360 as shown in FIG. 16 - 17, or a damper 360 with one or more damper holes.
