Description

  The present invention relates to an improvement of an aquarium, and more particularly to an aquarium capable of breeding ornamental fish in a good environment.

Conventionally, when breeding ornamental fish such as guppy and other embryonated fish, as shown in FIGS. 4 and 5 , a small egg-laying box 41 is installed in the aquarium 54 where the ornamental fish are bred, and egg laying is performed. The parent fish 14 whose period has come close is accommodated in the egg-laying box 41 so as to protect the egg 15 that has been laid and the fry that has just been born (egg embryo) 16.

That is, as shown in FIGS. 4 and 5, in such a conventional spawning box 41, a bottom portion having a substantially V-shaped cross section in which a slit 36 is formed in the valley along the width direction. 32 is provided, and the spawning box 41 is divided into upper and lower rooms 52, 53 by the bottom 32, the parent fish 14 is stored in the upper room 52, and the eggs that the parent fish 14 have laid down in the lower room 53. 15 and fry 16 are accommodated.

  The slit 36 is formed in a width dimension through which only the egg 15 and the fry 16 can pass, and the parent fish 14 cannot pass through. Therefore, when the parent fish 14 in the upper room 52 lays the eggs 15 or the fry 16, the eggs 15 and the fry 16 fall into the lower room 53 through the slit 36, and the eggs 15 and the fry 16 are in the parent fish. The fry 16 is configured to be bred and isolated from the parent fish 14 in the lower room 53 so that the fry 16 is not preyed on.

  In such a conventional breeding method using the small egg-laying box 41, the parent fish 14 reared in the aquarium 54 is transferred to the egg-laying box 41 at a timing close to the egg-laying season, and the egg-laying environment is changed. I try to secure it.

However, in general, it is difficult to accurately determine whether or not the parent fish 14 is in the spawning season unless it is a skilled breeder, and the time to move the parent fish 14 to the spawning box 41 is missed. There is a possibility that the parent fish 14 lays eggs not in the spawning box 41 but in the aquarium 54 and the eggs 15 and fry 16 are preyed on by the parent fish 14 and other fish 55.
Moreover, there is a possibility of giving stress to the parent fish 14 due to the transfer, or possibly damaging the parent fish 14 itself.

  Even if the parent fish 14 can be safely transferred to the spawning box 41, the spawning box 41 is small, so the swimming space for the parent fish 14 is limited, which causes stress on the parent fish 14, and the parent fish 14 itself, May adversely affect the eggs of the parent fish 14 and the health of the fry. Further, since the egg-laying box 41 is small, it may be difficult to store a plurality of parent fish 14.

  In addition, the spawning box 41 is provided with a plurality of water passage holes 51 on, for example, the side surface, and the water passage holes 51 are formed to be narrow in order to prevent the fry 16 from passing through. Water circulation between the box 41 and the water tank 54 may not be performed sufficiently. As a result, the food and excrement left over by the parent fish 14 and the fry 16 may stagnate at the bottom of the spawning box 41, leading to deterioration of the water quality of the entire aquarium 54.

  Furthermore, since the slit 36 formed in the valley portion of the bottom 32 is formed in a size that allows the fry 16 to pass through, the fry 16 that has grown and can swim in the lower room 53 has the slit 36. Further, there is a possibility that the parent fish 14 will be preyed by moving to the upper room 52 through the center.

In view of such conventional problems, the present patent applicant conducted a pre-application search, searched for related patent application information, and extracted related Patent Document 1 below. In the said patent document 1, the small egg-laying box installed in a water tank is disclosed and it turns out that it has the same problem as the above.

As shown in FIG. 3, the spawning water tank 12 is also formed in a truncated inverted quadrangular truncated pyramid shape having an opening 31 at the top, similarly to the breeding water tank 11, and the front plate portion 17 and the back plate portion 18. , And side plate portions 19 and 20 joined to end portions of the front plate portion 17 and the back plate portion 18, and the front plate portion 17, the back plate portion 18 and the side plate portion 19, 20 is formed in an inverted isosceles trapezoidal shape in which the upper base dimension is larger than the lower base dimension.
Further, the front plate portion 17 and the back plate portion 18 of the spawning aquarium 12 have the same base angle α as the side plate portion 43 and the back plate portion 44 of the breeding aquarium 11, and the spawning water tank 12. The side plate portions 19 and 20 have the same base angle β as the side plate portions 45 and 46 of the breeding water tank 11.
Therefore, as shown in FIG. 1, when the spawning water tank 12 is inserted into the breeding water tank 11 through the opening 22 during use, the front plate portion 17, the back plate portion 18 of the spawning water tank 12, The side plate portions 19 and 20 are in close contact with the front plate portion 43, the back plate portion 44, and the side plate portions 45 and 46 of the breeding aquarium 11, respectively, and the spawning water tank 12 is fixed in the breeding aquarium 11. Is done.

  Further, the height of the egg-laying aquarium 12 is about 3/4 of the height of the breeding aquarium 11, and a handle 33 is provided on the inner side of the upper ends of the side plate portions 19 and 20, respectively. It is configured so that the user can hold it when the spawning water tank 12 is attached or detached.

  As a result, when the spawning water tank 12 is inserted and arranged in the breeding water tank 11 through the opening 22, the spawning water tank 12 is disposed on the four side surface portions 43 of the breeding water tank 11 as shown in FIG. 1. , 44, 45, 46 from the inside and is fixed in the breeding aquarium 11 in a state where a gap is formed between the bottom plate 47 of the breeding aquarium 11 and the gap is connected to the fry growing part 13.

Further, in the present embodiment, the bottom 32 of the laying aquarium 12, the same transparent synthetic resin and laying aquarium 12, alternately peaks and valleys are corrugation you continuously in the width direction It is formed as a plate material and covers the lower part of the spawning water tank 12. In the present embodiment, three peak portions 49 are formed along the length direction of the egg-laying water tank 12, and inclined portions 50 are formed at both ends.

  In the bottom portion 32, slits 36 are formed along the width direction between the three peak portions 49 and between the peak portion 49 and the inclined portion 50, respectively. In this case, four slits 36 are provided along the length direction of the egg-laying water tank 12. The slit 36 is formed in such a width dimension that only the egg 15 or the fry 16 produced by the parent fish 14 in the spawning aquarium 12 can pass and fall to the fry growing part 13 while the parent fish 14 cannot pass through.

In addition, three hole portions 37 are provided at equal intervals along the width direction at the top portions of the three peak portions 49 and the inclined portion 50, respectively. It is formed in a diameter that cannot pass.
In addition, only the hole part 37 is formed in the inclined part 50 formed in the both ends of the length direction of the bottom part 32, and the slit is not formed. This is because, in general, fish have a habit of swimming along the wall surface, and therefore, when a slit is provided, the fry 16 is prevented from moving into the spawning aquarium 12 through the slit. .

As shown in FIGS. 1 and 2, the aquarium 10 according to the present embodiment is provided with a water circulation device 21 that can suck and filter the water in the fry growing section 13 and reduce it into the spawning aquarium. ing.
The water circulation device 21 is formed in the tube portion 24 inserted through the through-hole 38 in the bottom portion 32 of the spawning water tank 12 and the lower end portion of the tube portion 24, and is opened in the fry growing portion 13. A water inlet 25 having a strainer 26 that prevents the fry 16 from being sucked in, and an upper end of the pipe 24, the water sucked through the water inlet 25 is filtered and returned to the breeding aquarium 11. A filter part 27 is provided.

  As shown in FIG. 1, the water circulation device 21 attaches and fixes the spawning water tank 12 to the breeding water tank 11, and then, for example, filters the filter 27 to the rear plate parts 44 and 18 of the breeding water tank 11 and the spawning water tank 12. The pipe 24 is suspended in the spawning water tank 12 and inserted into the through hole 38 of the bottom 32, and the water suction port 25 is arranged in the fry growing part 13 for use. To do.

  The filtration unit 27 is provided so as to be joined to the motor 28a for pumping up the water in the fry growing unit 13, the pipe unit 28b for feeding the pumped water, and the pipe unit 28b, and includes, for example, a hollow fiber curtain. A filtration unit main body (not shown) provided with a filter, and a discharge port 28c for discharging the filtered water to the spawning water tank 12 are provided. Reference numeral 29 is a power cable for supplying electricity to the motor 28a.

Hereinafter, the operation of the water tank 10 according to the present embodiment will be described.
In the aquarium 10 according to the present embodiment, the parent fish 14 is bred in the spawning aquarium 12. In this case, the spawning water tank 12 is formed to be substantially the same size as the rearing water tank 11, and unlike the conventional one, there is a very large swimming space. Can be kept in a good environment for a long time. Therefore, it is possible to eliminate the adverse effects on the health of the fish body derived from the stress of the parent fish 14 resulting from the limited swimming space of the parent fish 14, and the adverse effects on the health of the eggs in the fish and the fry.

  When the parent fish enters the spawning season, the eggs 15 or the fry 16 are dropped. The eggs 15 and the fry 16 that have been spawned fall to the fry growing part 13 through the slits 36 formed between the peaks 49 of the bottom 32 of the spawning water tank 12.

  Since the slit 36 and the hole 37 are formed in such a diameter that the parent fish 14 cannot pass through, the fry growing part 13 is completely isolated from the parent fish 14 in the spawning aquarium 12. The situation where 16 is preyed by the parent fish 14 can be completely prevented.

  The uneaten portion of the food provided to the parent fish 14 and the excrement of the parent fish fall into the fry growing part 13 through the slit 36. However, in the aquarium 10 according to the present embodiment, the water circulation device 21 is provided, and when the water circulation device 21 is activated, the motor 28a causes the inside of the fry growing unit 13 to pass through the water suction port 25. Water, fallen bait, excrement, etc. are sucked and sucked up through the pipe part 24, filtered as appropriate in the filtering part 27, become clean water, and again into the spawning aquarium 12 from the drain port 28c. Supplied.

  As a result, the water circulation layer device 21 forms a flow of clean water that recirculates from the fry growing section 13 provided at the bottom of the aquarium 10 to the upper end of the spawning tank 12. The water tank 13 is maintained in a good water quality state, and clean water is also supplied into the spawning water tank 12 to ensure circulation of clean water from the bottom to the top in the water tank 10 as a whole. The water environment of 10 whole can be maintained favorable. In addition, since the strainer 26 is attached to the water inlet 25, the fry 16 and the egg 15 are not accidentally sucked from the water inlet 25.

  In the aquarium 10 according to the present embodiment, water discharged from the drain port 28c falls into the spawning aquarium 12 due to the operation of the water circulation device 21, so that the fry growing part 13 is formed from the upper part of the aquarium 10. A water flow from the upper part to the lower part is formed.

  Since this water flow passes through the slit 36 at the bottom 32 of the egg-laying water tank 12, a low-pressure water flow is formed in the slit 36 from above to below. As a result, it is impossible for the fry 16 in the fry growing section 13 to pass through the slit 36 against this water flow and reach the spawning tank 12, and the fry 16 is preyed by the parent fish 14. It can be prevented almost completely.

  Moreover, since the water flow from the upper part in the tank 10 to the fry growing part 13 passes through the slit 36 and the pressure of the water flow is increased, the breeding water in the fry growing part 13 is further stirred by the low-pressure water flow. Thus, the breeding environment of the fry growing section 13 can be improved.

  In addition, the air collected in the fry growing part 13 generated below the bottom part 32 can be extracted to the opening part 31 through the hole part 37.

  In addition, regarding the specific structure of the breeding water tank and the egg-laying water tank according to the present invention, the material, and the specific structure of the water circulation device, it is not limited to the above embodiment.

INDUSTRIAL APPLICABILITY The present invention can be used in aquariums that can be widely applied to spawning parent fish and has industrial applicability.
