Description

  The present invention relates to an aquatic organism breeder and an aquatic organism breeding system. Specifically, for example, the present invention relates to an aquatic organism breeder and an aquatic organism breeding system for raising abalone and tocobushi.

Growing shellfish, that is, aquaculture, can be broadly divided into marine culture and land culture.
Underwater aquaculture is a method in which a plate with juvenile shellfish attached is surrounded by a net and lowered into the sea for growth. Therefore, there is an advantage that it is easy to prepare an environment relatively close to the natural habitat state.

  However, underwater aquaculture is susceptible to seawater contamination, and it is necessary to feed, clean, and harvest on board the ship. There was a problem that it was difficult to harvest as desired.

On the other hand, onshore farming does not have such problems of undersea farming. And conventionally, various technologies related to land farming have been proposed.
For example, Patent Literature 1 describes a culture device as shown in FIG.
In other words, the aquaculture device 101 described in Patent Document 1 includes an aquaculture tank 110, a nitrogen production device 120, an oxygen production device 122, and a fine bubble generating means 124.

In addition, a diffuser tube 123 is disposed in the water tank 110.
Further, the air diffusion pipe 123 is connected to the high concentration oxygen gas outlet 120A of the nitrogen production apparatus 120 via the pipe 121B.

Here, an opening type recovery port 121A is provided on the upstream side of the pipe 121B, and the opening type recovery port 121A is arranged in the vicinity of the high concentration oxygen gas discharge port 120A.
A blower device 127 is disposed in the pipe 121B between the air diffuser 123 and the nitrogen production device 120. The blower device 127 can mix external air and high-concentration oxygen gas and send them to the diffuser pipe 123.

Moreover, the oxygen production apparatus 122 is connected to the diffuser pipe 123 via the pipe 121B.
Further, an air diffuser 125 is disposed in the water tank 110. The air diffuser 125 is connected to the outlet of the fine bubble generating means 124.

  Moreover, the shellfish to be cultivated are placed on a bottom net stretched in the water tank 110 or are suspended and held by a hanging string.

It is the schematic which shows the conventional aquaculture apparatus.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to facilitate understanding of the present invention.
FIG. 1 is a schematic front view showing an example of a shellfish breeder to which the present invention is applied. FIG. 2 is a schematic side view of a shellfish breeder to which the present invention shown in FIG. 1 is applied.
1 and 2 is the upper side in the vertical direction, and the lower side in FIGS. 1 and 2 is the lower side in the vertical direction.

  The shellfish breeder 1 of this invention shown in FIG. 1 and FIG. 2 is arrange | positioned inside the shellfish breeding tank which is a water tank for growing shellfishes, such as an abalone and a tocobushi. Shells are an example of aquatic organisms.

Moreover, the shellfish breeder 1 of this invention is equipped with a pair of vertical board 2 extended in a perpendicular direction and having light-shielding property. Here, the vertical plate is an example of a vertical member.
Moreover, the shellfish breeder 1 of this invention is provided with the inclination board 3 which has light-shielding property.
Further, the inclined plate 3 has a vertical upper surface inclined in the vertical direction, and is attached to the vertical plate 2 so as to protrude.
Here, the inclined plate is an example of a first protruding member.

Moreover, the shellfish breeder 1 of this invention is equipped with the horizontal board 4 which has light-shielding property.
Further, the horizontal plate 4 is attached to the vertical plate 2 so as to protrude from a position different from the position of the inclined plate 3 in the vertical direction and the horizontal direction. Further, the horizontal plate 4 has a horizontal surface on the upper side in the vertical direction.
Here, the horizontal plate is an example of a second protruding member.

Here, the position of the inclined plate 3 and the position of the horizontal plate 4 mean positions based on the respective centers of the inclined plate 3 and the horizontal plate 4.
When the inclined plate 3 arranged on the same horizontal plane and the horizontal plate 4 arranged on the same horizontal plane are used as one combination unit, the inclined plate 3 is arranged in the horizontal plate 4 as shown in FIG. It is arrange | positioned in the vertical direction diagonally rather than.

  Each of the pair of vertical plates 2 has a through hole (not shown) penetrating between one surface and the other surface parallel to the one surface.

The shape of the through hole is a rectangle. That is, the shape of the through hole is substantially the same as the shape of the thickness region of the plate member.
Moreover, the form of the through hole is a form inclined in the vertical direction or a horizontal form.
Therefore, the inclined plate 3 and the horizontal plate 4 are projected and attached to the vertical plate 2 by inserting the plate-like member through each through hole.

Further, the inclined plate 3 and the horizontal plate 4 that protrude from and attach to the pair of vertical plates 2 are composed of one member at the same position in the vertical direction as shown in FIG.
That is, one plate-like member is inserted through the through hole of one vertical plate 2 and is inserted through the through hole of the other vertical plate 2.

Since the inclined plate 3 and the horizontal plate 4 have light shielding properties, light from the upper side in the vertical direction is blocked by the inclined plate 3 and the horizontal plate 4.
Accordingly, the vertical direction of the surface of the inclined plate 3 facing downward in the vertical direction, the surface of the horizontal plate 4 facing downward in the vertical direction, or the position of the vertical plate 2 where the inclined plate 3 or horizontal plate 4 is attached. The lower area becomes particularly dark, and nocturnal shellfish are likely to adhere to these surfaces and areas.

  Further, since the horizontal plate 4 is attached to the vertical plate 2 so as to protrude from the vertical plate 2 at a position different from the position of the inclined plate 3 in the vertical direction and the horizontal direction, the inclined plate 3 and the horizontal plate 4 are arranged in steps. In other words, shellfish food such as algae can be passed between the inclined plate 3 and the horizontal plate 4, and light can be easily blocked from the upper side in the vertical direction.

Moreover, since the surface of the inclined plate 3 on the upper side in the vertical direction is inclined in the vertical direction, the food of the shellfish thrown in from the upper side in the vertical direction is likely to fall to the lower side in the vertical direction.
Since the shellfish breeder 1 of the present invention is arranged in a shellfish breeding tank in which shellfish are already accommodated, there are many shellfish at the bottom of the shellfish breeding tank, and the vertical direction of the shellfish breeder 1 of the present invention. Since the bait thrown from the upper side becomes easy to fall to the lower side in the vertical direction, the shellfish present in the bottom of the shellfish breeding tank can easily eat the bait.

Further, the shellfish can move along the vertical plate 2 and reach the inclined plate 3 and the horizontal plate 4 positioned on the upper side in the vertical direction.
Moreover, since the surface of the horizontal plate 4 on the upper side in the vertical direction is horizontal, the food of shellfish thrown in from the upper side in the vertical direction is unlikely to fall down on the lower side in the vertical direction, and is easily collected on the horizontal plate 4.

Furthermore, as shown in FIG. 1, the end of the inclined plate 3 and the horizontal plane of the horizontal plate 4 are located on the same line in the vertical direction.
Therefore, the bait that has fallen obliquely downward in the vertical direction along the inclined surface of the inclined plate 3 tends to fall on the horizontal plane of the horizontal plate 4.

  As a result, the shellfish can obtain food collected on the horizontal plate 4 positioned on the upper side in the vertical direction, and can move upward along the vertical plate 2 in the vertical direction. Since the inclined plate 3 is disposed, an area where light is blocked by the inclined plate 3 is generated, and nocturnal shellfish are likely to stay there.

Thus, the shellfish breeder of the present invention can make shellfish stay in a three-dimensional and wide range in the shellfish breeding tank, and the water in the shellfish breeding tank, for example, water having a high dissolved oxygen concentration is brought into contact with many shellfish. be able to.
As a result, the amount of oxygen intake by the shellfish increases, and the growth efficiency of the shellfish can be improved.

In addition, as shown in FIG. 1, the inclined plate 3 and the horizontal plate 4 are arranged in steps, so that the food that has accumulated on the horizontal plate 4 and overflows from the horizontal plate 4 It passes between the horizontal plates 4 and falls downward in the vertical direction.
Moreover, since the horizontal plane on which the inclined plate 3 is located and the horizontal plane on which the horizontal plate 4 is located are alternately present as shown in FIG. 1, the bait overflowing from the horizontal plate 4 is obliquely below the horizontal plate 4 in the vertical direction. It falls on the inclined surface of the arranged inclined plate 3.

  Then, the bait that has fallen on the inclined surface of the inclined plate 3 falls downward in the vertical direction along the inclined surface of the inclined plate 3 and falls on the horizontal plane of the horizontal plate 4. The fall of food (sinking) is this repetition.

Further, as shown in FIG. 1, a part of the inclined plate 3, that is, a certain region from the end of the inclined plate 3, and a part of the horizontal plate 4, that is, a constant region from the end of the horizontal plate 4, Are located on the same line.
That is, when the inclined plate 3 and the horizontal plate 4 are viewed from above in the vertical direction, the end of the horizontal plate 4 is hidden by the inclined plate 3 and cannot be seen.

In addition, valve sockets 5 are attached through the four corners of the vertical plate 2 and in the vicinity of the edge of the vertical plate 2 extending in the vertical direction, that is, the approximate center of the longitudinal edge.
The valve socket 5 attached to one vertical plate 2 and the valve socket 5 attached to the other vertical plate 2 are connected. As a result, the shape of the shellfish breeder 1 of the present invention is stabilized.

  The vertical plate 2, the inclined plate 3, and the horizontal plate 4 are made of plastic, but may be made of other materials as long as they have light shielding properties.

In the aquatic organism incubator of the present invention, at least the upper surface of the first projecting member does not necessarily have to be inclined in the vertical direction.
However, it is preferable that at least the surface on the upper side in the vertical direction of the first projecting member is inclined in the vertical direction, because the aquatic bait introduced from the upper side in the vertical direction easily falls down in the vertical direction.

Further, in the aquatic organism incubator of the present invention, at least the surface on the upper side in the vertical direction of the second projecting member is not necessarily horizontal.
However, it is preferable that at least the surface on the upper side in the vertical direction of the second projecting member is horizontal, since the aquatic organisms thrown in from the upper side in the vertical direction are unlikely to fall down in the vertical direction and are likely to collect on the second projecting member. .

In the aquatic organism incubator of the present invention, the part of the first projecting member and the part of the second projecting member do not necessarily have to be located on the same vertical line.
However, it is preferable that a part of the first projecting member and a part of the second projecting member are located on the same line in the vertical direction because light from the upper side in the vertical direction is more easily blocked.

That is, the septic tank 14 is connected to a conduit 19 between the discharge pipe 17 and the first gas dissolving device 8 so as to communicate therewith.

Here, ceramics are a lump of minerals in which no organic matter exists, and minerals are basically positive ions, so they attract oxygen of negative ions and vibrate water vigorously.
And water is vibrated vigorously to make the water cluster smaller, and to promote precipitation separation of organic matter and gas that were present in the gaps between water molecules. The “water cluster” is an aggregate formed by connecting water molecules with hydrogen bonds.

In addition, ceramics vibrate water violently, thus suppressing water decay.
In addition, the water whose water cluster has become smaller can carry the activated water to every corner of the organism, so that the organism can grow healthy.
In addition, decomposition of ammonia generated from organic substances is promoted by water in which oxygen is dissolved.

  Further, a chiller 15 for keeping the temperature of water passing through the conduit 19 constant is attached to the conduit 19 between the discharge pipe 17 and the first gas dissolving device 8.

In addition, supply pipes 18 that extend in the short direction of the shellfish breeding tank 6 and communicate with the inside of the shellfish breeding tank 6 are attached to opposite side walls.
In addition, one end of a bifurcated conduit 19 is attached to a supply pipe 18 that extends in the short direction of the shellfish breeding tank 6 and is attached to each of opposite side walls.

  The other end of the conduit 19 having one end attached to the supply pipe 18 is attached in communication with the first gas dissolving device 8.

An oxygen cylinder 9 is connected to the first gas dissolving device 8 in communication therewith. Therefore, the first gas dissolving device 8 can dissolve oxygen in water using oxygen in the oxygen cylinder 9.
Specifically, the first gas dissolving device 8 can drive out nitrogen-rich air dissolved in water and replace it with pure oxygen.

By replacing the nitrogen-rich air dissolved in the water with pure oxygen, it is possible to obtain dissolved oxygen water having a high concentration without bubbles.
That is, a pure oxygen dissolved amount of about 4.8 times that of general air dissolution can be obtained.
Thereby, since a dissolved oxygen concentration appropriate for aquatic organisms can always be obtained, it is possible to grow abalone and flybugs with high density.

Further, the discharge pipe 17 and the supply pipe 18 attached to the algal tank 7 are communicated with each other through a conduit 19.
A circulation pump 12 is connected to the conduit 19 in communication.

Further, a carbon dioxide cylinder 11 is attached to the second gas dissolving apparatus 10 so as to communicate therewith. Therefore, the second gas dissolving apparatus 10 can dissolve carbon dioxide in water using the carbon dioxide in the carbon dioxide cylinder 11.
Specifically, the second gas dissolving device 10 can expel the nitrogen-rich air dissolved in the water and replace it with carbon dioxide.

By replacing carbon-rich air dissolved in water with carbon dioxide, high-concentration carbon dioxide-dissolved water can be obtained without bubbles.
That is, the amount of dissolved carbon dioxide is about 2,800 times that of general air dissolution.

  Thereby, since the dissolved carbon dioxide concentration always appropriate for aquatic organisms can be obtained, cultivation of high-density algae becomes possible.

  Further, an oxygen cylinder 9 is connected to the second gas dissolving apparatus 10 in communication therewith. Therefore, the second gas dissolving apparatus 10 can also dissolve oxygen in water using oxygen in the oxygen cylinder 9.

Further, the LED lighting device 24 is immersed in the water put in the algal tank 7.

Moreover, the shellfish breeding system of this invention does not necessarily need to be equipped with a septic tank.
However, if the shellfish breeding system of the present invention is provided with a septic tank, since divalent iron or trivalent iron functions to reduce fresh water or seawater, it is preferable because decay can be suppressed and water pollution can be suppressed.

Next, the flow of shellfish breeding by the shellfish breeding system 1A of the present invention will be described.
A plurality of shellfish breeders 1 of the present invention are arranged in a shellfish breeding tank 6 in which abalone is accommodated.
Further, groundwater is introduced into the shellfish breeding tank 6 from the raw water introduction pipe 20 of the shellfish breeding tank 6.

  On the other hand, groundwater is also introduced into the algae tank 7 from the upper side in the vertical direction, for example, and algae in the initial growth stage is introduced from the upper side in the vertical direction.

  And the circulation pump 12 connected to the shellfish breeding tank 6 and the algae tank 7 through the conduit | pipe 19 is driven, respectively, and the groundwater accommodated in the shellfish breeding tank 6 and the algae tank 7 is circulated.

Further, groundwater is discharged from the discharge pipe 17 of the shellfish breeding tank 6 and introduced into the first gas dissolving device 8 through the conduit 19.
Then, oxygen is dissolved in the groundwater by the first gas dissolving device 8 to increase the dissolved oxygen concentration, and the groundwater with the increased dissolved oxygen concentration is discharged from the first gas dissolving device 8, and the supply pipe 18 is discharged through the conduit 19. Is supplied again to the shellfish breeding tank 6.

  Further, as shown in FIG. 4, the supply pipe 18 is attached to the vertically lower side of the shellfish breeding tank 6, that is, the bottom, so that the groundwater with the increased dissolved oxygen concentration flows evenly from the bottom to the top. be able to.

Therefore, the shellfish breeding tank 6 is always filled with groundwater having a high dissolved oxygen concentration. Moreover, since the dissolved oxygen concentration is high, the oxygen intake of shellfish is improved, and the growth efficiency of shellfish is improved.
In addition, since groundwater with an increased dissolved oxygen concentration is supplied to the bottom of the shellfish breeding tank 6, the dissolved oxygen concentration in the lower layer of water in the shellfish breeding tank 6 can be increased, and feces and food staying in the lower layer The residue remains an aerobic environment without decaying, and the generation of anaerobic bacteria that are mostly pathogenic bacteria can be suppressed.

In addition, since the groundwater in which the dissolved oxygen concentration is increased flows evenly so as to rise from the bottom of the shellfish breeding tank 6 to the top, the aquatic organism extends from the lower layer of the water in the shellfish breeding tank 6 to the upper side in the vertical direction, that is, the upper layer. Therefore, it is possible to create an environment having an appropriate dissolved oxygen concentration.
Therefore, compared with the aeration system, the vertical region length of the vertical member of the aquatic organism incubator of the present invention is increased because the oxygen-rich water region in the shell growing tank is larger in the vertical direction in the system of the present invention. And the amount of cultivation per unit area can be significantly increased.

  Further, the temperature of the circulating groundwater is kept at 20-27 ° C., preferably 25-27 ° C., by the chiller 15.

On the other hand, groundwater is taken from the intake pipe 17 </ b> B of the algal tank 7 and introduced into the second gas dissolving apparatus 10 through the conduit 19.
Then, the second gas dissolving device 10 dissolves carbon dioxide in the ground water to increase the dissolved carbon dioxide concentration, and the second gas dissolving device 10 discharges the ground water having the increased dissolved carbon dioxide concentration, and passes through the conduit 19. The supply pipe 18 supplies the algal tank 7 again.

  Furthermore, since the LED lighting device 24 is arranged inside the algal tank 7, photosynthesis occurs due to the carbon dioxide dissolved in the groundwater and the light of the LED, and the algal propagation efficiency is improved.

Further, the feeding pump 16 is driven to collect the algae grown in the algae tank 7 from the algae collection pipe 17A and introduce it into the shellfish breeding tank 6 through the algae supply pipe 21.
Therefore, in addition to abundant oxygen, algae as a food for shellfish is supplied, so that the growth efficiency of shellfish is further improved.

  Moreover, although raising of shellfish, such as an abalone and Tokobushi, was demonstrated, it is not necessarily limited to this. The aquatic organism breeder and the aquatic organism breeding system of the present invention are also suitable for raising crabs and shrimps, for example.

  As described above, the aquatic organism breeder of the present invention and the aquatic organism breeding system of the present invention can improve the growth efficiency of aquatic organisms.
