Description

The present invention relates to a water tank split container. More specifically, the present invention relates to a tank divided container in which the breeding space of an aquatic organism breeding aquarium for breeding ornamental fish such as medaka and other aquatic organisms is divided into a plurality of areas, and each can be bred according to the growth process, sex and the like.

Traditionally, hobbies include breeding ornamental fish such as goldfish and tropical fish and other aquatic organisms. In particular, in recent years, the number of people who breed medaka indoors has increased, especially among aquatic organisms, because it does not require large-scale equipment or equipment, is relatively easy to breed, and is easy to start. doing. Hereinafter, in the present specification, medaka will be mainly assumed as an aquatic organism and will be described.

It is generally known that medaka fish enter the breeding season when the water temperature is high from spring to autumn and the daylight hours are long. Therefore, by appropriately controlling the water temperature in the aquarium using a heater, etc., and adjusting it to the same daylight hours using an LED lighting device, etc., and irradiating the light, all year round, including winter. Medaka can be spawned. Therefore, it is possible to spawn medaka and breed medaka more easily than goldfish and tropical fish. Therefore, in addition to simply enjoying it as an aquarium fish, medaka can be bred or different varieties can be crossed to create new varieties. You can also enjoy it as a breeder, such as creating medaka fish, and the number of people who enjoy breeding medaka fish is increasing.

At present, it is said that there are at least 500 kinds of improved medaka fish. And, in order to maintain the orthodox pedigree of medaka for breeding and avoid crossing with medaka of other varieties, medaka of different varieties should not be bred in the same tank, but bred for each cultivar. Is the basis for breeding medaka.

As described above, medaka is provided in aquatic plants, algae, or in an aquarium when the water temperature and sunshine duration reach conditions suitable for spawning (for example, water temperature: 20 to 25 ° C., sunshine duration: 13 hours or more). Eggs are laid on an artificial spawning bed or the like. Then, when the laid eggs hatch, they gradually grow larger and grow in the order of larvae (seamstresses) → fry → juveniles → young fish → adult fish, gradually changing the growth process.

At this time, if medaka fish and eggs having different growth processes are mixed and bred in the same aquarium, the medaka fish having a long growing period may eat the medaka fish or eggs having a short growing period as food. That is, there is a risk of cannibalism in which the parent medaka eats the eggs after spawning, or the adult medaka eats medaka such as fry smaller than itself. Therefore, in order to protect the eggs laid on the spawning bed from the parent medaka, the work of promptly collecting them from the aquarium and transferring them to another aquarium, and avoiding the mixing of medaka with different growth processes such as adult fish and fry. In addition, it was necessary to keep them in separate aquariums.

Furthermore, in order to confirm the sex of the medaka, it is necessary to scoop one by one with a net and determine the characteristics of the sex each time, and such work may hurt the medaka or give excessive stress to the medaka. was there. Therefore, in order to complete this work only once, the medaka fish whose sexes have been confirmed may be divided into males and females and bred in different aquariums. As described above, it was necessary to manage and breed medaka by finely dividing the aquarium and the breeding space according to the growth process, the variety, or the sex.

Here, as the aquarium (breeding container) used for breeding medaka, for example, a transparent aquarium used for breeding goldfish made of glass, plastic such as acrylic resin, tropical fish, etc. may be used, or a heat insulating effect may be used. A box made of high-quality foamed styrol is used as a substitute for a breeding container, and a plastic costume case or the like is diverted as a breeding container.

That is, it is possible to store a predetermined amount of water to secure a space (breeding space) in which medaka can be bred, and to maintain watertightness without leakage of the water from the breeding space in which the water is stored. If possible, it can be used as a breeding container for medaka without particular limitation.

In addition to the above-mentioned aquarium, various configurations and various incidental facilities may be required for medaka breeding in order to prepare the medaka breeding environment (growth environment). For example, in the breeding space where water is stored, bottom sand such as river sand is laid on the bottom according to the environment of medaka that inhabits the natural world, and aquatic plants, algae, or spawning beds are installed for egg laying. I may do it.

On the other hand, an "air pump" that adjusts the amount of oxygen in the water stored in the breeding space and manages it to be suitable for breeding medaka, and collects medaka excrement, food residue and garbage from the water. A "filter" that keeps the water clean, a "heater" for adjusting the water temperature to conditions suitable for spawning, and a "lighting device" for adjusting the above-mentioned sunshine time are attached to the water tank as ancillary equipment. May be done. Since such ancillary equipment has already been well known in the past, detailed description thereof will be omitted here, and the presentation of prior art documents regarding the water tank and the ancillary equipment will also be omitted.

As explained above, in order to breed medaka, it was necessary to install many aquariums for each variety and growth process. However, it has been difficult to secure a sufficient installation space (medaka breeding space) for placing many aquariums in ordinary households and the like.

In addition, in addition to the water tank, it is necessary to install the above-mentioned ancillary equipment and the like for each water tank, and there is a problem of installation space and an increase in installation cost including the water tank and the ancillary equipment.

Furthermore, even if many aquariums are installed, the medaka fish bred in each aquarium can be fed, the water quality and temperature can be controlled in each aquarium, and chemicals can be administered to adjust the water quality. The required work increased dramatically depending on the number of aquariums installed, which sometimes forced an excessive burden for breeding medaka fish. Therefore, even those who enjoy breeding medaka and creating new varieties as a hobby should abandon the breeding due to the excessive burden as described above, or limit the breeding of medaka. was there. That is, there was a possibility that the breeding of medaka could not be fully enjoyed.

In addition, a small container (for example, a capacity of about 1 to 5 liters) or the like is also used as a water tank for breeding medaka. However, it is difficult to install the above-mentioned incidental equipment such as a heater and a filter for each container (water tank), and the water quality deteriorates or the amount of water stored is small, so that a large water tank (for example, a capacity of 10 to 80 liters) is used. Compared with the degree), there was a problem that the water temperature was affected by the change in the ambient temperature and was liable to fluctuate. Therefore, a simple aquarium with a small size can be considered to have a sufficiently prepared medaka habitat, and may not be suitable for breeding or breeding medaka.

Furthermore, the distributors who handle medaka may also need a large number of water tanks, such as temporarily managing the medaka individually for shipping or managing them separately for males and females. In the above, although the explanation was mainly given to medaka, similar problems may occur in other aquatic organisms and the like. For example, when fishing, you may go to the fishing spot with various kinds of live food such as horse mackerel and live shrimp, and even in this case, store and transport them separately so that multiple live foods are not mixed. I needed it.

Therefore, in view of the above circumstances, the present invention can secure a plurality of breeding spaces for breeding ornamental fish such as killifish and other aquatic organisms even in a narrow space, depending on the deterioration of water quality and the surrounding environment. An object of the present invention is to provide a water tank split container that is not easily affected by water temperature and the like and can be bred for medaka or the like by segregating for each growth process, each variety, each sex, and the like. Another object of the present invention is to provide a water tank split container that can be used for storing and transporting live food in fishing.

According to the present invention, a water tank split container that solves the above problems is provided.

According to the aquarium division container of the present invention, the breeding space of the aquatic organism breeding tank can be divided into a plurality of compartments and can be bred in one tank of medaka with different growth processes and varieties. As a result, it is not necessary to set many water tanks, and the problem of installation space and the installation cost can be suppressed.

In addition, although the mesh part of the aquarium split container regulates the movement of killifish (including eggs) between the spaces inside each container, water can flow, so ancillary equipment such as heaters and filters Can be shared. Therefore, the installation cost of such ancillary equipment can be suppressed, and the water quality and temperature can be shared and managed, and the breeding environment of medaka can be stabilized.

Further, the float portion installed in the container body makes it possible to install the aquarium division container of the present invention in a floating state in the breeding space, while reducing the amount of water in the breeding space and dividing the aquarium. Even when the container is not installed in a floating state, a gap having a predetermined height can be formed between the inner bottom surface of the water tank and the bottom surface of the container by the container legs. As a result, it is possible to avoid crushing the killifish that live in the breeding space with the aquarium split container of the present invention.

In addition, even when transferring medaka or eggs to another water tank, etc., water can be stored in a part of the breeding space of the container body, and the medaka can be moved without imposing a load on the medaka. Etc. can be completed.

Hereinafter, embodiments of the water tank split container of the present invention will be described in detail with reference to the drawings. The water tank split container of the present embodiment is not particularly limited to the following embodiments, and various design changes, modifications, improvements, etc. can be added as long as the gist of the present invention is not deviated. is there. In the following, the description is made mainly assuming the breeding of medaka, but the present invention is not limited to this, and can be suitably used for the divided storage of live food in fishing. ..

As shown in FIGS. 1 to 8, the aquarium division container 1 of the embodiment of the present invention is a medaka breeding aquarium 2 for breeding medaka M1, M2, M3, medaka egg E, etc. The breeding space 3 of the aquarium 2) is divided into a plurality of parts, and the medaka M1 and the like are bred in the space 4 in each container according to the growth process, sex and the like. In the water tank split container 1 of the present embodiment, medaka M1, medaka M2, and medaka M3 are distinguished from each other according to the difference in the growth process, and are collectively referred to as medaka M1 and the like (see FIG. 2). ..

Here, the aquarium 2 corresponds to the aquatic organism breeding aquarium in the present invention, and the medaka M1 and the like and the medaka egg E correspond to the aquatic organism in the present invention. In the aquarium division container of the present invention, the breeding space in which aquatic organisms are bred includes a storage space for temporarily storing live food for fishing and the like. As the water tank 2, for example, a well-known one made of a transparent material such as glass or plastic such as acrylic resin can be used, and the water tank 2 is not particularly limited.

By accommodating one or more of the aquarium division containers 1 of the present embodiment in the breeding space 3, the aquarium 2 configured to have one breeding space 3 before the division has an area larger than that of the initial breeding space 3. And / or it can be divided into a container inner space 4 having a smaller volume. Here, the space 4 in the container is used as a new breeding space for the medaka M1 and the like. Further, the medaka M1 or the like may be bred in the outer space 5 of the container, which is the outer space of the inner space 4 of the container.

Further, in the aquarium division container 1 of the present embodiment, the capacity of the breeding space 3 in the assumed aquarium 2 is not particularly limited. For example, a water tank 2 having a general capacity of about 60 liters or 30 liters can be used. That is, by using the aquarium division container 1 of the present embodiment, as an example, a plurality of aquarium division containers 1 having a capacity of 10 liters of the container inner space 4 are accommodated in the breeding space 3 of the aquarium 2 having a capacity of 60 liters. However, it can be divided into each breeding space. It should be noted that the space between the aquarium division containers 1 adjacent to each other, in other words, the medaka M1 and the like may be bred in the container outer space 5 which is the breeding space 3 other than the container inner space 4.

As a result, it is possible to avoid breeding different medaka M1 and the like (including medaka egg E; the same applies hereinafter) in the same breeding space 3 for each growth process, each breed, each sex, etc. Water 6 can be shared and bred in one aquarium 2 (see FIG. 2). Here, FIG. 2 shows that four aquarium division containers 1 of the present embodiment are housed in the breeding space 3 of the aquarium 2, and the medaka eggs E of the medaka eggs E and the medaka M1 of the size corresponding to the growth process are accommodated in the respective container inner spaces 4. An example of breeding M2 and M3 respectively is shown. Note that FIG. 2 shows an example of using the water tank split container 1 of the present embodiment, and the number and arrangement of the water tank split containers 1 to be accommodated in the water tank 2, the size and shape of the water tank split container 1, and the like are shown. It is not particularly limited and can be set arbitrarily.

Explaining the specific configuration of the water tank split container 1 of the present embodiment mainly based on FIGS. 1 and 3 and 4, the water tank split container 1 is erected from the container bottom surface portion 7 and the container bottom surface portion 7. A container main body portion 10 having an upper opening 9 opened upward while forming a container inner space 4 surrounded by a pair of one container side wall portion 8a and the other container side wall portion 8b, and a container side wall portion. The movement of the medaka M1 and the like provided in at least a part of 8a and separated by the container inner space 4 and the container main body 10 is restricted, and the water 6 in the container inner space 4 and the container outer space 6 It is mainly provided with a mesh portion 11 that enables the distribution of the above (see FIG. 1 and the like).

The container main body portion 10 is arranged so that one of the container side wall portions 8a faces each other and the other container side wall portions 8b face each other. Further, as shown in FIG. 1 and the like, the water tank split container 1 has a substantially rectangular parallelepiped shape, and the upper opening 9 slightly expands with respect to the bottom surface portion 7 of the container, that is, one side wall portion 8a of the container. The side wall portion 8b of the container and the other side wall portion 8b are each inclined.

Here, the material constituting the water tank split container 1 of the present embodiment is not particularly limited, and for example, a polypropylene resin material is used as the container body 10 or a polypropylene fiber is used as the mesh portion 11. It is possible to use a resin material such as, which is formed by knitting into a mesh shape. Furthermore, it can be formed of other materials.

The inner space 4 of the water tank split container 1 and the outer container outer space 5 of the water tank split container 1 are provided with a mesh portion 11 of one container side wall portion 8a, the other container side wall portion 8b, and the container bottom surface portion 7. The medaka eggs E, medaka M1, etc., which are larger than the mesh structure of the mesh portion 11, cannot move horizontally between the container inner space 4 and the container outer space 5 because they are partitioned by. , Water 6 smaller than the mesh structure can be circulated.

Therefore, ancillary equipment such as an air pump and a filter for adjusting the water quality and water temperature can be shared in the breeding space 3 of the aquarium 2, and these managements can be collectively carried out in the entire aquarium 2. Therefore, the medaka M1 and the like can be bred separately for each growth process while maintaining the growth environment of the medaka in a stable state.

Further, the aquarium division container 1 of the present embodiment can further include a float portion 12 that generates buoyancy with respect to the water 6 stored in the breeding space 3. By providing the float portion 12 in the container main body portion 10, the aquarium division container 1 can be floated on the water 6 stored in the breeding space 3. The float portion 12 may be detachably attached to the float mounting portion 13 provided on the container main body portion 10.

The material of the float portion 12 is not particularly limited, and a foaming material or the like having a lighter specific gravity than that of water 6 can be used. In the water tank split container 1 of the present embodiment, the float portion 12 is formed of foamed polyethylene as a material.

The float mounting portion 13 is integrally formed with the container main body portion 10, is separated in the vertical direction at a predetermined interval, projects horizontally from the container side wall portion 8 of the container main body portion 10, and is formed in the container main body portion 10. It is composed of a pair of float mounting pieces 14a and 14b formed along the longitudinal direction (corresponding to the left-right direction of the paper surface in FIG. 3). Here, since the height H1 of the pair of float mounting pieces 14a and 14b in the vertical direction and the height H2 of the float portion are formed so as to substantially coincide with each other, the float is formed between the float mounting pieces 14a and 14b. The portion 12 can be inserted and inserted (see FIGS. 3 and 4).

As shown in FIG. 4, the float mounting portions 13 are provided on the side wall portions 8 of the container facing each other. In other words, it is provided so as to be symmetrical in the right side view of the water tank split container 1 in FIG. As a result, it can float on water 6 in a stable state.

On the other hand, the float portion 12 can be easily removed from the float mounting portion 13. As a result, when the depth of the water 6 in the breeding space 3 is not sufficient, the aquarium division container 1 can be accommodated in the breeding space 3 in a submerged state without floating on the water 6. That is, the floating / sinking state of the water tank split container 1 of the present embodiment can be appropriately adjusted according to the water depth of the water 6 and the state of attachment / detachment of the float portion 12.

In the water tank split container 1 of the present embodiment, the mounting position of the float portion 12, in other words, the position of the float mounting portion 13 in the container body portion 10 is a specified height from the opening edge 9a of the upper opening portion 9 of the container body portion 10. It is provided at a lower position so far apart (see FIGS. 3 and 4). As a result, when the aquarium split container 1 is floated on the water 6 in the breeding space 3 using the float portion 12, the opening edge 9a of the upper opening 9 of the container main body 10 protrudes from the water surface 6a of the water 6. It will be located above by the protrusion height H3 (= specified height) (see FIG. 5).

Therefore, for example, the medaka M1 bred in the container inner space 4 of one of the aquarium split containers 1 (on the right side of the paper in FIG. 5) jumps over the side wall portion 8a of one container and the upper opening 9 of the medaka located next to it. It is restricted to move to the inner space 4 of the other aquarium division container 1 (the left river on the paper in FIG. 5) in which the egg E is bred and the outer container space 5 between the aquarium division containers 1 adjacent to each other. As a result, it is possible to prevent medaka eggs E, medaka M1 having different growth processes, and the like from being mixed in the container inner space 4 or the container outer space 5.

On the other hand, the water tank split container 1 of the present embodiment has a plurality of container legs that project downward from the bottom surface 7a of the bottom surface 7 of the container body 10 and can come into contact with the bottom surface 2a of the water tank of the water tank 2. It is configured to further include 15. In the water tank divided container 1 of the present embodiment, the container legs 15 are provided at a total of four locations near the four corners of the container bottom surface 7 having a substantially rectangular shape.

By having such a container leg 15, for example, the medaka M1 is already bred in the breeding space 3, and the water depth is shallow enough that the aquarium split container 1 of the present embodiment cannot be floated on the water 6. Even so, a predetermined gap S (see FIG. 6) is formed between the water tank split container 1 and the water tank inner bottom surface 2a, and problems such as the medaka M1 being pinched do not occur.

In particular, in the case of medaka M1 and the like, it is known that when a foreign enemy or a human figure is seen, they try to hide by entering a small gap or the like in order to protect themselves. Therefore, when there is no configuration related to the container leg portion 15 as in the water tank split container 1 of the present embodiment, the bottom surface 7a of the flat bottom surface portion 7 and the bottom surface 2a inside the water tank are in close contact with each other, and a gap S is formed. It no longer exists. As a result, the medaka M1 and the like may be delayed in escaping, and the medaka M1 and the like may be crushed by the water tank split container 1.

On the other hand, according to the water tank split container 1 of the present embodiment provided with the container leg portion 15, the above-mentioned problem occurs because the gap S is formed between the outer surface 7a of the bottom surface portion and the inner bottom surface 2a of the water tank. There is little chance of doing it. In the water tank split container 1 of the present embodiment, the container legs 15 are provided at the four corners of the bottom surface of the container 7, but the present invention is not limited to this, and the gap S can be formed. For example, the number of container legs 15 is not particularly limited.

Further, in the water tank split container 1 of the present embodiment, the mesh lower end portion 11a of the mesh portion 11 is provided at an upper position separated from the inner surface 7b of the bottom surface portion 7 of the container bottom surface portion 7 of the container body portion 10 by a specified height. .. For example, the height H4 at the lower end portion from the inner surface 7b of the bottom surface portion to the lower end portion 11a of the mesh can be set to about 22 mm. As a result, even when the aquarium division container 1 is lifted from the breeding space 3 in which the water 6 is stored, the first storage space 16a (lower end portion) formed between the inner surface 7b of the bottom surface portion and the lower end portion 11a of the mesh is formed. A part of the water 6 can be stored in the position height H4), and the water 6 is not completely discharged from the container inner space 4 of the water tank split container 1 (see FIG. 7).

As a result, even when the medaka M1 or the like bred in the container space 4 is moved to another breeding space 3 or when cleaning work such as water change in the breeding space 3 of the aquarium 2 is performed, a short time is required. If so, the medaka M1 and the like can swim in the first storage space 16a, and the work can be performed without imposing a heavy burden. Further, the first storage space 16a can be preferably used when moving the medaka M1 or the like to another water tank (not shown) or a container or the like.

Further, as shown in FIG. 1 and the like, the mesh portion 11 of the water tank split container 1 of the present embodiment has at least a part having an inverted trapezoidal shape, and the first mesh portion 17a having the mesh hypotenuse portion 18 and the first mesh portion 17a. It has a second mesh portion 17b having a substantially square shape arranged side by side with the mesh portion 17a, and is configured on one of the container side wall portions 8a. The first mesh portion 17a has an inverted trapezoidal shape, and the mesh oblique side portion 18 is formed substantially opposite to the other container side wall portion 8b of the container main body portion 10, so that, for example, as shown in FIG. 8, the container When the main body 10 is tilted toward the other container side wall 8b (left side of the paper in FIG. 8), water 6 is placed in the second storage space 16b surrounded by the container bottom surface 7 and a part of the other container side wall 8b. It can be stored.

As a result, even when the medaka M1 or the like is transferred from the container inner space 4 of the water tank split container 1 to another container, a water tank, or the like, the medaka M1 or the like is not lifted from the water 6, and a certain amount of water 6 is secured. Then, the work can be performed with the medaka M1 or the like swimming. In this way, a part of the mesh portion 11 provided on the side wall portion 8a of the container is formed in an inverted trapezoidal shape, and the oblique side portion 18 of the mesh is provided to hold a part of the water 6 in the space 4 inside the container. Various operations can be performed in the state.

In the case of the water tank split container 1 of the present embodiment, as shown in FIGS. 1, 3 and 4, with respect to one of the container side wall portions 8a located in the front direction of the paper surface and the depth direction of the paper surface in FIG. A mesh portion 11 composed of a first mesh portion 17a and a second mesh portion 17b is provided, respectively, and the other side wall of the container in the left direction of the paper surface and the right direction of the paper surface in FIG. The mesh portion 11 is not provided for the portion 8b. By adopting such a combination configuration, it is possible to easily perform the transfer work, water change work, etc. of the medaka M1 and the like without causing great damage to the medaka M1 and the like and the medaka egg E.

Further, in the water tank divided container 1 of the present embodiment, the container main body 10 may be colored with a single color of any one of black, white, brown, and blue. Here, it is known that in general ornamental medaka M1 and the like, the body color of the medaka M1 and the like changes depending on the surrounding color (backland reaction). Therefore, when breeding medaka M1 or the like, the environment of the surrounding color is extremely important. Further, it is known that such a tendency is greatly influenced by the breeding container and the breeding space 3 in the growth process.

Therefore, the body color of the medaka M1 or the like to be bred can be adjusted by forming the aquarium division container 1 of the present embodiment, in particular, by forming the color of the container main body 10 with the above-mentioned single color. More specifically, it is generally known that there are four types of chromatophores contained in medaka M1 and the like: yellow chromatophore, black chromatophore, white chromatophore, and iridophore. It is known that, depending on the breed of medaka M1 or the like to be bred, medaka M1 or the like having a well-colored color can be bred by using a breeding container such as black from the breeding stage. Therefore, even in the water tank split container 1 of the present embodiment, the container body portion 10 having a single color can be used. In the water tank split container 1 of the present embodiment, the black container body 10 is used.

As shown above, according to the aquarium division container 1 of the present invention, the breeding space 3 of the aquarium 2 can be divided into a plurality of container inner spaces 4 and partitioned. This makes it possible to prevent cannibalism between the medaka fish M1, M2, and M3 due to the difference in the growth process. Further, the medaka M1 and the like to be bred for each variety can be divided by the partitioned container space 4 and the like to prevent crossbreeding of the varieties such as the medaka M1 and the medaka M1 and the like can be bred for each sex. In this way, the movement of the medaka M1 and the like can be physically regulated.

Further, the float portion 12 of the aquarium division container 1 can divide the breeding space 3 in a floating state or a submerged state in the water 6. Further, even when the medaka M1 or the like is moved by the first storage space 16a or the second storage space 16b provided in the container inner space 4 of the water tank split container 1, the medaka M1 or the like is damaged. It is possible to move the medaka M1 and the like while swimming. As a result, the medaka M1 and the like are not weakened.

Further, since the water 6 can be distributed between the inner space 4 of the container and the outer space 5 of the container, the water 6 can be shared. Therefore, by installing one additional equipment such as an air pump and a filter that have been known conventionally for one water tank 2, the water quality, the amount of saturated dissolved oxygen, and the saturated dissolved oxygen amount in the container inner space 4 in the water tank split container 1 can be determined. The water temperature etc. can be managed collectively. As a result, the influence of the water temperature and the influence of the water quality due to the surrounding environment can be suppressed as compared with the case where the medaka M1 or the like is bred in a small container as in the conventional case. As a result, the medaka M1 and the like can be bred in a narrow space without increasing the number of aquariums, and the medaka M1 and the like can be bred in a stable growing environment.

The aquarium split container of the present invention can be particularly preferably used in the breeding of aquatic organisms such as medaka and the breeding of aquatic organisms that require a plurality of aquariums in order to create new varieties. Further, in the case of fishing, the aquarium division container of the present invention can be preferably used even when a large number of types of live food are stored and transported in a state of being individually separated.
