(Points of interest)
In general, the conventional increased-increased Atkins hatching tank used by private aquaculture farmers can hold up to about 500,000 fish eggs per section (one section and two sections), giving a large amount of fresh water flow at once. It has the characteristic that it can hatch eggs and is excellent in productivity, but it is possible to compartmentalize and manage multiple varieties of eggs such as rainbow trout, char, trout, and Ito in one hatching tank There is a disadvantage that it can not be done, and if an infection such as water mold disease occurs in a large number of eggs, treatment with labor and expense such as drug treatment is forced, and it should be a certain measure However, due to its structure, there are many cases in which infection spreads over a wide range, and as a result, it has become a factor that significantly reduces the eye rate.

    In addition, the increased yield type Atkins hatching tank is designed to contain hundreds of thousands of eggs and equalize the flow of water with the weight of those eggs. If the amount is extremely small, the flow of water will be biased, and eggs that should be in a stationary state will die due to excessive movement (light impact), or eggs in areas where flow is poor In some cases, the number of eggs collected is from several thousand to several tens of thousands to several hundred to several hundreds of grains. There is a risk that the eye rate may be greatly reduced due to the above reasons, and if the purpose is to research using biotechnology, different fish may be treated by gene processing such as chromosome doubling. One egg is mixed into other types of fish eggs Unacceptable, when trying to perform such high-precision management, it is necessary to prepare multiple hatching tanks, so research cannot proceed efficiently. there were.

(Conventional technology)
(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as typified by what is proposed in Patent Document 1 (1) below, a cylindrical member body extending in the vertical direction includes a net member and a fluid discharge mechanism, and the fluid discharge mechanism includes: A sleeve tube is connected to the air supply unit, and includes an air inflow tube that extends into the sleeve tube and guides air into the sleeve tube, and circulates and agitates the water in the apparatus body. It is possible to supply air (especially oxygen) into the water and change it to fresh water so that a good water environment can be secured at all times, or a partition as shown in Patent Document 1 (2). An unillustrated foam mixing prevention mechanism that provides a head difference between the water supply groove defined by the plate and the hatching tank main body, and provides a seed egg floating prevention net on the drainage surface to guide the water supply upward in the water supply groove. And a vigorous and uniform water flow is obtained. Incubation water is made to flow sequentially into a water increase type hatching tank that can supply a large amount of oxygen, or a water tank that contains a large number of fish eggs, such as Patent Document 1 (3). Open the downstream end of the water supply pipe that leads to the inside of the water tank at a position lower than the water surface in the water tank, and guide the hatching water supplied from the water supply pipe into the water tank over the water surface in the water tank and again into the water tank. A guide member is provided to reduce bubbles in the water supplied to the aquarium as much as possible. Bubbles adhere to the fish eggs, hindering the hatching, and the fish eggs suffocate and die. There are some things that can prevent this well.

However, the hatching tanks for fish eggs as shown in Patent Documents 1 (1) and (2) contain fish eggs that are grouped in one tank, If an infectious disease such as a disease occurs, there is a risk that the detection of dead fish eggs will be delayed or the infected fish eggs will be lost, and the infection will be unlimitedly contaminated by many fish eggs in the tank. In addition, in the hatching apparatus for fish eggs as shown in the former Patent Document 1 (3), when a plurality of cylindrical apparatus main bodies are to be used, an air pump is provided in an air inflow pipe provided for each unit. If the connection management workability is difficult and an infection has occurred in the cylindrical device body, remove the cylindrical device body from the tank and remove the eggs and fry. It must be disassembled and opened to prevent leakage, etc. Fatal drawback that very inconvenient Te was still left.

(Awareness of problems)
As mentioned above, all of the previously proposed hatching devices for fish eggs are not suitable for use unless they contain a large amount of single species of eggs in a hatching tank at a time and hatch. In addition, it is difficult in terms of structure to prevent the occurrence of large numbers of infectious diseases, and it has the disadvantages that it cannot accommodate a small amount of various types of fish eggs. In the case where a plurality of device main bodies are installed and used in a water tank, a large amount of labor is required for attaching / detaching and opening / closing individual device main bodies. Rather, the number of parts that form each device body increases, leaving the problem of being burdened with an economic burden. Development, provision of a wide variety of fry and adult fish Based on the various knowledge gained from these experiences and information from private aquaculture companies, I have been engaged in various activities, as well as the functions of the hatching apparatus and the production process. With regard to the configuration for enabling the egg to be stably and efficiently eyed, the need for further improvement has been felt.

(Object of invention)
Therefore, the present invention is a new hatching tank that can stably and efficiently generate a small amount of fish eggs, greatly reduce the burden of breeding management, and can significantly reduce manufacturing costs. As a result of the long-term trial and error, many trial productions, and experiments, we decided to develop a new structure. The hatching apparatus has been successfully realized, and the configuration thereof will be described in detail below together with an embodiment representative of the present invention shown in the drawings.

(Structure of the invention)
As clearly understood from the embodiments representing the present invention shown in the drawings, the hatching apparatus of the present invention basically comprises the following configuration.
That is, a hatching chamber provided with a hatching chamber partitioned by a partition wall plate and a partition bottom plate, guiding water injection from the water supply port to the drainage port direction via the hatching chamber, and a hatching tank capable of maintaining a steady flowing water environment; The inlet provided at the lowermost end so as to serve also as the installation port for the partitioning bottom plate in the hatching tank, the rising water diffusion cell provided directly above the predetermined range and the rising water diffusion cell via the fish egg receiving net In the hatching tank partition bottom plate so that it can be freely fitted and removed, and protrudes from the surface of the water flowing into the hatching chamber to a height range substantially corresponding to the height of the hatching tank periphery. In the desired direction of the water flowing upward, the hatching tank partition is composed of a combination with a subdivided container having an egg-breeding cell with a notch that is provided with a fish egg loss prevention network and communicated with the hatching chamber in the desired direction. On the bottom plate, a plurality of these subdivided containers are combined in a planar arrangement. The individual inlets are in close contact with the positions of the inlets of the subdivided containers when the arrangement is regulated so that the small gaps necessary for the desorption operation are placed in order and can be neatly established. A hatching device having a configuration in which sockets that can be detachably mounted are arranged in a vertically penetrating manner on the partition bottom plate by an amount corresponding to the number of subdivided containers and integrated.

    If the hatching device having this basic configuration is shown as a more specific one, one or a plurality of hatching chambers partitioned by a partition wall plate and a partition bottom plate are provided, An inlet provided at the lowest end so as to serve as an installation port for the hatching tank in which the water injection is guided to the outlet through the hatching chamber to maintain a steady flowing water environment and the hatching tank partition bottom plate, The ascending water diffusion cell provided directly above the predetermined range and the ascending water diffusion cell are arranged so as to be continuously fitted on the partitioning bottom plate in the hatching tank so as to be continued immediately above the fish egg receiving net. In this state, it protrudes from the surface of the water that has flowed into the hatching chamber and reaches a height range approximately equivalent to the height of the periphery of the hatching tank. Subdivision container having a small egg-shaped egg-growing cell provided with a cut-out opening The hatching tank partition bottom plate has a flat shape corresponding to a plurality of subdivided containers, and the partition bottom plate includes a group of these subdivided containers arranged in a plane arrangement. The individual inlets are fitted in close contact with the positions of the inlets of the subdivided containers when the arrangement is restricted so that the small gaps necessary for the detachment operation are placed in order. The hatching apparatus has a configuration in which sockets that can be removably attached are arranged in a vertically penetrating manner on the same partition bottom plate as many as the subdivided containers.

    As described above, according to the hatching apparatus of the present invention, unlike the conventional one, from the unique characteristic configuration as described above, if it is the conventional one, a set of fish eggs in one hatching tank If an infectious disease occurs, it is possible to removably install multiple subcontainers in a single hatching tank that has been greatly affected by the occurrence of infectious diseases. However, it becomes possible to take out individual processing containers from the hatching tank and process them, making it possible to detect and remove dead dead eggs early and effectively prevent infection of surrounding subdividing containers. In addition to significantly increasing the eye rate, the burden of breeding and management can be greatly reduced compared to conventional hatching tanks such as the Atkins hatching tank (trade name). Houses different types of eggs in the tank It is possible to install a plurality of subdivided containers, so we can expect much from the previous ones, which will be able to propagate a much smaller variety of fish eggs much more efficiently than conventional products. Excellent characteristics that could not be obtained.

    In addition, one or more hatching chambers are provided in particular, and a plurality of continuous chambers are provided, and a partition bottom plate having a flat shape corresponding to a subdivided container made into a group is incorporated in each incubation chamber in the hatching tank. In the case of things, compared to the case of only a single hatching room, more eggs of various varieties can be accommodated, and the stagnation of water current can be averaged out as much as possible, and it dies. The effect of reducing fish eggs can be greatly expected, and it leads to the early detection and removal of dying dead fish eggs, which dramatically improves production efficiency and the time and cost required for biotechnology technology experiments and research, etc. This will have a great effect of significantly reducing the cost.

    Each subdivided container has a built-in ascending water diffusion cell, and the entire flow of the hatching tank can be forcibly diffused in each cell. As well as making sure that fresh water can be distributed evenly throughout the fishing eggs at any time, it is possible to prevent the oxygen deficiency phenomenon reliably, and the unglazed balls (for example, the brand name Cristobalite) It is possible to add a purification and sterilization action by adopting a commercially available ball having a purification and sterilization function as a funnel-like shape. If the formed one is used, the diameter of each inlet of the subdivided container (installation port) and each socket of the partition bottom plate is reduced, and the distance between the sockets is further increased as compared with the case of the size cylinder shape over the entire length. Secure large, It is easy to manufacture sockets, and the durability of the partition bottom plate can be increased. In addition, the operation of attaching and detaching each sub-container can be made much easier, further increasing the efficiency of raising and managing fish eggs. Thus, the effect of allowing the inflow water to the rising water diffusion cell to be reduced and rising to the egg breeding cell can be obtained.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The hatching tank bears the function of making it possible to maintain a constant flowing water environment in the hatching chamber and maintaining an environment suitable for hatching the fish eggs contained in each hatching chamber. More specifically, Various incubators such as an Atkins type incubator, a revenue-increasing type Atkins type incubator, a box type incubator, or a floatation tank can be used as they are, or modified in part. As shown in Fig. 4, if the increased-incidence Atkins type incubator is used, the partition wall plate can be incorporated without processing, so that it is extremely advantageous from the standpoint of assembling the apparatus and can be economically superior. it can.

    The partition wall board shall have a function of partitioning each hatching chamber so that water can pass through, and the water injection should be able to be guided without stagnation so that the bottom of each hatching chamber rises and drains upward from the side. For example, a partition wall plate divides each hatching chamber, and a water circuit is formed separately from the hatched water channel to form a water circuit and supply water to the vicinity of the bottom of the hatching chamber located at the head of the water flow. In addition, it is possible to sequentially inject water near the bottom of the next hatching chamber adjacent from the top of the hatching chamber, and to allow drainage from the top of the hatching chamber arranged at the end. As shown in the figure, the upper edge of the partition wall plate is set higher than the flowing water surface, and the lower edge is set slightly higher than the bottom surface of the hatching chamber, a water inlet is opened on the bottom surface, and water is injected from the water inlet. Supply to the bottom of the hatching chamber located at the top, and the downstream of the hatching chamber An intermediate partition plate whose upper end edge is set slightly lower than the flowing water surface, and whose lower end edge coincides with the bottom surface of the hatching chamber, and in order to secure a flow path between the intermediate partition plate The upper edge is set higher than the water surface, and the lower edge is set slightly higher than the bottom surface of the hatching chamber, and a partition wall plate with a water passage opening is provided on the bottom surface so that the upper end of the leading hatching chamber can be seen. The drained water is supplied to the vicinity of the bottom of the next adjacent hatching chamber, and the downstream is adjacent to the trap through the intermediate partition plate arranged downstream of the hatching chamber and the partition wall plate facing it. Water can be sequentially poured near the bottom of the hatching chamber, and the shape can be regulated so that it can be guided to be fed from the vicinity of the upper end of the hatching chamber located at the tail end of the downstream to the drain.

    The partition bottom plate has a function of allowing a plurality of sub-containers to be detachably installed in the incubation chamber of the incubation tank, and the bottom of the incubation chamber is used for water injection supplied to the vicinity of the bottom of the incubation chamber. It functions as a partition that separates each sub-container in close contact with the space (below the water inlet) and the space of the sub-chamber where the sub-containers are installed (above the water inlet). A plurality of sockets to be made should be arranged at appropriate intervals, and the rising pressure of the water injected through each socket should be in a shape that can generate a rising water flow (with a water pressure appropriate for fish breeding) in each sub-container. In addition, as shown in the examples described later, it is possible to form a clog-like support leg so that the position on the floor for pouring water can be maintained.

    The socket has a water passage part that penetrates the top and bottom of the partition bottom plate at the appropriate place on the partition bottom plate, and the installation port (inlet) of the subdivided container is detachably attached to the water passage part so that it can be detachably attached. It is possible to perform the function of supporting the sub-container in an upright manner, and a plurality of sub-containers are placed on the partition bottom plate in a plane arrangement with a small gap necessary for desorption operation between them. When the arrangement is restricted so that it can be neatly arranged, it must be provided at a position that matches each inlet position of the subdivided containers. Thus, it is preferable that the outer diameter of the pipe-shaped portion serving as the installation port (inlet) for the subdivided container is set to a cylindrical shape having an inner diameter that can be fitted and removed in a close contact manner.

    The subdivision container divides the hatching chamber in the hatching tank into smaller fish egg storage compartments, takes out the individual hatching chambers, performs various operations, and then mounts them again for rearing and management. In the hatching chamber, the bottom end should be installed in a flat arrangement so that it can be placed in an orderly manner with a small gap necessary for desorption operation between them, and also used as an installation port for the partition bottom plate The rising water diffusion cell provided above the predetermined range and immediately above the inlet, and the rising water diffusion cell are connected to the upper part of the hatching tank through the fish catching net and onto the partition bottom plate in the hatching tank. In a state where it is detachably installed, it protrudes from the surface of the water flowing into the hatching chamber and reaches a height range substantially corresponding to the height of the periphery of the hatching tank. With a notch that communicates with the hatching room It must have an egg-shaped egg-laying cell, and from the installation port (inlet) to the ascending water diffusion cell and the egg-growing cell are of the same-shaped shell-type, Thus, as long as there is no inconvenience in the water flow, such as in the case of using a discarded plastic bottle, the shape is not particularly limited and can be freely selected.

    When using a plastic bottle as in the examples described later, if it is a waste plastic bottle, it should be washed thoroughly, and then the bottom of the container is added to the container upside down by processing such as excising the bottom. It can be manufactured by combining various necessary parts such as a socket made of a PVC pipe that can be screwed or fitted into the cap screw part of the mouth, and a thick plate that fixes them in a predetermined arrangement, In this case, for example, any one of commercially available PET bottles such as 500 ml, 900 ml, 1000 ml, and 2000 ml can be appropriately selected and used.

    The sub-container installation port (inlet) can be fitted to any one of the sockets of the partition bottom plate so that the sub-container can be detachably attached in a compatible manner. It is possible to supply running water from the cell to the egg laying cell, and to carry out the function of allowing the subcontainer to be attached to the socket so that it can stand on its own. As shown in the examples to be described later, it is possible to incorporate an intermediate pipe part such as an adapter if necessary, and in particular, a subdivided container made of PET bottles. In many cases, even with various types of PET bottles, the caps of the installation port (inlet) have many different shapes according to the standard of the beverage packaging container industry. The divided container becomes easier to capable embedded with compatible be advantageous ones.

    The ascending water diffusion cell has a function of buffering, dispersing and depressurizing the injected water that flows from the sub-container installation port (inlet) into the egg laying cell in a diffused manner to reduce the jet pressure. It should be equipped with obstacle-like members, labyrinth-like piping passages, porous members, etc., and with a built-in filter material that can provide sterilization or purification action, etc. Desirably, for example, it is possible to contain a filter, a mesh, a predetermined amount of granular material or powdered material, and more specifically, glass balls, plastic balls, pebbles, sand, calcined zeolite, which will be described later. As shown in the embodiment, it can be an unglazed ball containing cristobalite, or a mixture thereof. Needless to say, when such a granular material is accommodated, an installation port (inlet) is used. It, and Ikutamago cell must be assumed that the formation of the locking structure part dam so as not to leak into the ring.

    The fish catching net allows the fish eggs contained in the egg breeding cell to be held so that the rising water diffusion cell does not fall into the trap, and the flowing water from the installation port (inlet) rising water diffusion cell passes to the egg breeding cell. It is to share the functions to be possible, and must have a mesh size, shape and strength that can hold fish eggs so that they do not fall off, and is held with sufficient strength so that they do not fall off accidentally In the case of maintenance, it is desirable to make it easy to attach and detach, made of material, as shown in the examples described later, when the subdivided container is made of plastic bottle, It is good to set it as the synthetic resin net | network set to the shape which can be detachably fitted to the protruding item | line part which protrudes toward the inner side of the uneven | corrugated shaped part of a PET bottle.

The egg laying cell forms a fish egg storage part in the subdivided container, and allows the flowing water from the installation port (inlet) ascending water diffusion cell to pass upward and be maintained so that it can be discharged, and securely holds the fish egg. It should share the function of allowing only water to drain from the upper appropriate position, and should be a cylindrical shape with the upper end open, as shown in the examples described later. In addition, a notch opening for drainage is formed, and a fish egg loss prevention net made of a synthetic resin set to a mesh smaller than the fish egg is attached to the notch opening.
