Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to the provision of a water layer for fish cultivation suitable for the feeding period of, for example, "larval flounder".

Problems to be solved by conventional techniques and ideas In general, in the cultivation of flounder in aquariums, during the feeding period for flounder fry (the period during which fry with a total length of 1 to 5 cm are fed approximately 30 days after hatching), the fry Since they settle on the bottom of the aquarium and often overfeed, it becomes extremely difficult to remove leftover food and excrement, and if they are neglected or removed insufficiently. , causing pathogen outbreaks. In addition, if the size of the fry is not sorted according to their growth, they will cannibalize, so frequent sorting is required, but since the fry are attached to the bottom, it is difficult to scoop them out of the aquarium, causing damage to the fish body. There are problems such as having to do a lot of things.

Therefore, management of young flounder in aquarium fish culture is extremely troublesome and has many problems.

The purpose of the present invention is to provide a fish culture water layer with a new structure that solves the above-mentioned conventional problems.

Means for Solving the Problems The fish tank of the present invention that achieves the above objectives has a water supply section at one end and a drainage section at the other end, and has a section near the water supply section that is transversally divided by a net-like partition. It consists of a rearing section and an accumulation section near the drainage section, and a vertically recessed groove is formed in the center of the bottom of the rearing section, and the groove is removably covered with a net-like lid. separated from the breeding section, and further,
The stacking section has an upright structure connected to the bottom of the stacking section.
It is characterized by a structure in which a drainage section consisting of a drainage pipe that can be freely tilted is provided, and a drainage pipe that can be raised and tilted is provided at the end of the groove section.

Effects and Examples Hereinafter, the structure and effects of the fish culture water layer of the present invention will be explained in detail based on the drawings of examples. In FIGS. 1 to 6 showing an embodiment thereof, a water layer 1 for fish farming of the present invention (hereinafter simply referred to as aquarium 1) includes a water supply section 5 that receives a water supply pipe 5' at one end;
The other end on the opposite side forms a drainage section 6 connected to a drainage pipe 6', and the inside of the aquarium 1 is divided into a rearing section 3 and an accumulation section 4 transversely by a net-like partition 2. The rearing section 3 is located near the water supply section 5 and is large, and the accumulation section 4 is located near the drainage section 6.
It is located close to it and is divided into small sections. A groove 7 is formed in the center of the bottom of the rearing section 3 and is recessed over the entire length of the rearing section 3 in the vertical direction. At the end of the groove 7 near the drainage part 6, there is a drainage part to which a unique drainage pipe 10 is connected which can drain water, sediment, etc. in the groove 7.
In addition, the bottom of the rearing section 3 contains residual bait that has settled at the bottom.
A gentle slope is provided that gradually decreases in the direction from the water supply part 5 to the drainage part 6 so that miscellaneous waste such as excrement is guided to the accumulation part 4 by the water flow flowing from the water supply part 5 to the drainage part 6. It has been done.

In addition, as shown in FIGS. 5 and 6, both the partition body 2 and the lid body 9 are provided with a net having a mesh size that does not allow the fry to pass through the frame body, and the partition body 2 is
It is inserted into the insertion part 8 shown in the first figure in such a way that it can be freely fitted and removed, so that the remaining food on the bottom surface of the rearing part 3 can freely flow into the collecting part 4 through the partition 2, and the lid part 9 has a groove part. 7 is removably covered to prevent young fish from entering the groove section 7 from the rearing section 3.

In addition, both of the drain pipes 6' and 10 are configured to be able to stand up and tilt freely, and the water level in the water tank 1 can be adjusted by overflowing at an arbitrary angle θ as shown in FIG. It is possible to drain the water by tipping it over, take out the fry along with the water, or discharge and remove the accumulated part of leftover bait etc. as desired.

In addition, 12 in the figure is a water overflow window provided above the accumulation part 4, and 11 is a leg part of the water tank 1.

The aquarium 1 for fish farming of the present invention having the above configuration is a water tank 1.
The inside of the rearing section 3 is divided into a rearing section 3 and an accumulation section 4 by a net-like partition 2, and a groove section 7 having an independent drainage pipe 10 is provided at the bottom of the rearing section 3. For example, when frying flounder is placed in the tank for fish farming during the feeding period, the remaining feed and miscellaneous excreta of the fry are automatically collected and collected in the collecting section 4 by the flowing water of the aquarium 1, and the remaining feed, excrement, etc. A part of it settles in the groove 7 and is collected. and,
Among these accumulated materials, the accumulated miscellaneous waste in the accumulation section 4 is
For example, it can be freely discharged by a siphon, and the miscellaneous waste in the groove 7 can be removed to the outside of the water tank 1 along with the drainage by operating the drain pipe 10. and,
To prevent cannibalism, when sorting by size, remove the lid 9 and tilt the drain pipe 10 to drain the rearing section 3.
The flounder fry that have settled on the bottom can be easily taken out through the drain pipe 10 as the water flows.

Effects of the invention From the above, cleaning management of aquarium 1 and removal and selection of fry can be done extremely easily and efficiently. This method does not damage the young fish, keeps the aquarium clean at all times, and enables preferable breeding of young fish through frequent sorting, which has the excellent effect of making breeding management extremely simple and efficient.

Furthermore, according to the water layer 1 for fish farming of the present invention of the embodiment, the water level of the aquarium 1 can be freely adjusted by the drain pipes 6' and 10, so that floating matter and oil floating on the water surface due to feeding, for example, can be removed. If (oil adhering to the bait) occurs, raising the water level and allowing it to overflow from the overflow window 12 will immediately remove such floating matter. In addition, by continuously replenishing clean water and lowering the water level during the day when oxygen supplementation is particularly needed, and by raising the water level at night when oxygen supplementation is not particularly required, the amount of water supplied is limited. You can freely adjust the water level and save water. In addition, since the fish farming water layer 1 of the present invention can be arranged in a stacked manner in multiple stages, the bottom surface area is generally required to be excessively large due to the bottom-seating characteristics of flounder, and a large amount of hot water (during the cold season) and water supply amount are required. In the cultivation of young flounder, which requires water, there are practical advantages of securing effective space and saving and effectively using hot water, etc.

Other Embodiments The bottom slope of the rearing section 3 in the above structure of the present invention is provided with the intention of promoting the accumulation of miscellaneous waste in the accumulation section 4, and may be configured as a horizontal bottom.

Furthermore, the fish tank of the present invention can be used not only for flounder fry but also as a general fish tank.

As described above, the present invention provides a useful fish tank that has various practical effects such as simplifying and streamlining fish farming management.
