て、この孔３ａには清水供給室Ａに清水を供給す
るための注水管５が挿入されている。 1 is a wooden aquarium with a partition plate 1a inside.
The fresh water supply chamber A and the hatching chamber B are partitioned by. Note that these two chambers A and B are communicated at the bottom. In addition, a hole 1b is provided in the upper part of one side of the hatching chamber B (the surface facing the fresh water supply chamber A).
A step portion 1 having a diameter is formed, and this hole 1b
A drain pipe 2 is connected to the drain pipe 2. Reference numerals 3 and 4 designate lids that cover the upper surfaces of the two chambers A and B to prevent dirt and the like from entering the chambers A and B. A hole 3a is formed in the lid 3, and a water injection pipe 5 for supplying fresh water to the fresh water supply chamber A is inserted into the hole 3a.
６は孵化室Ｂ内の底面側に張設されたステンレ

水槽１の底部を通過して孵化室Ｂ内に導入され、
底網６、ネツトリング８、孵化盆７を介して水槽
１の段部１ｃより排水管２にて排水される。 Therefore, in the case of the above-mentioned flotation tank, incubation chamber B
When a large number of eggs C are placed in the hatching tray 7 inside and fresh water is injected from the water injection pipe 5, the fresh water passes through the bottom of the water tank 1 from the fresh water supply chamber A and is introduced into the hatching chamber B.
Water is drained from the stepped portion 1c of the aquarium 1 through the drain pipe 2 via the bottom net 6, net ring 8, and hatching tray 7.
このように、卵Ｃには常時清水が供給されるの
で、孵化が順調に行われると共に孵化した稚魚は
孵化盆７を通過してネツトリング８内に移動する
等して次第に大きくなる。また、稚魚のうちは稚
魚流出防止用網９にて、該稚魚の流出が防止され
ている。 In this way, since fresh water is constantly supplied to the eggs C, hatching is carried out smoothly, and the hatched fry gradually grow larger as they pass through the hatching tray 7 and move into the netting ring 8. In addition, outflow of young fish is prevented by a net 9 for preventing outflow of young fish.
そして、稚魚が十分に育成すると、稚魚流出防
止用網９が除去され、育成した稚魚は排水管２よ

浮上することが出来ず、死亡する等の問題があつ
た。
By the way, in the case of the flotation tank described above, water tank 1
Because wood is used as the material for the tank, water leaks easily from the joints, and the bulge of the side of the tank due to water pressure creates a gap between the bottom net and the side of the tank, and the bottom net drains through this gap. There were problems such as the fry that swam to the bottom were unable to surface and died.
また、清水の孵化室Ｂへの供給が清水供給室Ｂ
の底面より行われているために、注水管５よりの
清水供給を流速をつけて行わなければならない。
そのために、孵化室Ｂへ供給される清水には多量
の泡が含まれ、この泡が浮上する際、孵化盆７上
の卵Ｃを振動させてシヨツクを与え、殺してしま
うという問題も生じた。 In addition, the supply of fresh water to hatching room B is from fresh water supply room B.
Since fresh water is supplied from the bottom of the water supply pipe 5, fresh water must be supplied from the water injection pipe 5 at a high flow rate.
Therefore, the fresh water supplied to the hatching chamber B contains a large amount of bubbles, and when these bubbles rise to the surface, they vibrate the eggs C on the hatching tray 7, giving them a shock and killing them. .
さらに、清水供給室Ａよりの水流は、その流速
が大きいことから、孵化室Ｂの清水供給室Ｂとは
反対側の壁面に一旦当たつてから上方に流通する
ため、孵化室Ｂの中央部分における流速が低くな

い部分に集中し、その結果、水を汚染させ最悪の
場合、酸素欠乏によつて多数の稚魚が死ぬ等の問
題があつた。 Furthermore, since the water flow from the fresh water supply chamber A has a high flow velocity, it hits the wall surface of the hatching chamber B on the opposite side of the fresh water supply chamber B and then flows upward. The flow velocity at is lower. As a result, the hatched fry concentrate in this area of low flow velocity, resulting in water pollution and, in the worst case, a large number of fry dying due to lack of oxygen.

The above-mentioned flotation tank for fish farming has the aquarium itself made of a composite material of synthetic resin, which prevents water leakage and mortality due to fry getting caught, and eliminates the fresh water supply chamber from inside the aquarium, reducing the area of the hatching chamber. By increasing the amount of water and ensuring that fresh water is supplied from the bottom on average, hatching of eggs and raising of young fish are performed optimally.
次に本考案の一実施例を第１図、第２図と共に
説明する。なお、図中、前記した従来例の第３図
第４図と同一符号は同一部分を示し、説明は省略
する。
Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. In the figure, the same reference numerals as in FIGS. 3, 4, and 4 of the prior art example indicate the same parts, and the explanation will be omitted.
本考案において従来例と異なる点は、水槽１を
合成樹脂材の複合材で構成したこと、清水供給室
を無くすと共に清水供給バルブを水槽１の底面に
配置したことを特徴とする。 The present invention is different from the conventional example in that the water tank 1 is made of a composite material of synthetic resin, the fresh water supply chamber is eliminated, and the fresh water supply valve is placed on the bottom of the water tank 1.
以下、詳細に説明するに、水槽１は３層構造と
なつていて、内壁はアクリル樹脂板、外壁が
FRP材であつて、その間に発泡ウレタンにより
断熱材がサンドイツチ状態に挟まれている。 To explain in detail below, the aquarium 1 has a three-layer structure, the inner wall is made of acrylic resin, and the outer wall is made of acrylic resin.
It is made of FRP material, and the insulation material is sandwiched between them by foamed urethane in a sandwich state.
また、清水供給は水槽１の底部内に予め埋設さ
れた注水管５の先端に清水供給バルブ１０の下端
を接続すると共に、その下端部１０ａを同じく水
槽１の底部に埋設する。この清水供給バルブ１０
は下方から供給される清水を蓋板１０ａによつて
水平方向に放水すると共に蓋板１０ａにも多数の
小孔が形成され、この小孔からも上方に向かつて
放水されるものである。 Further, for fresh water supply, the lower end of the fresh water supply valve 10 is connected to the tip of the water injection pipe 5 buried in the bottom of the water tank 1 in advance, and the lower end 10a of the fresh water supply valve 10 is also buried in the bottom of the water tank 1. This fresh water supply valve 10
Fresh water supplied from below is discharged horizontally through the cover plate 10a, and a large number of small holes are also formed in the cover plate 10a, and water is also discharged upward from these small holes.
なお、図示のものは２つの水槽１を連結したも
のを示している。 Note that the illustrated one shows two water tanks 1 connected together.
而して、本考案にあつては、水槽１を合成樹脂
材の複合材によつて構成したことによつて、水漏
れの虞れがないと共に槽側面に水圧によるふくれ
もない為底網と槽側面のスキマを通じて稚魚が底
網下部に泳出することもない。 Therefore, in the present invention, since the water tank 1 is made of a composite material of synthetic resin, there is no risk of water leakage, and the sides of the tank do not bulge due to water pressure, so it is possible to use a bottom net. Young fish do not swim out to the bottom of the bottom net through the gap on the side of the tank.
また、清水は水槽１の中央に取付けた上方およ

給していることから、水槽１の全面に対し清水が
略均一に流れ、従つて、稚魚が一箇所に集中する
ようなことがなく酸欠による死も防止でき、しか
も、空気の泡も出難い構造から卵への悪影響を防
止できるものである。 In addition, since the fresh water is supplied by a fresh water supply valve installed in the center of the aquarium 1 that discharges water upward and horizontally, the fresh water flows almost uniformly over the entire surface of the aquarium 1, so that the fry can grow easily. It prevents the eggs from being concentrated in one place, which prevents them from dying due to lack of oxygen, and because the structure prevents air bubbles from forming, it prevents any negative effects on the eggs.
本考案は前記したように、水槽を合成樹脂材に

放水するように構成したことにより、水槽の全面
に対して清水が略均一に流れるようになり、稚魚
が一か所に集中するようなことがなくなり、従つ
て、稚魚が酸欠によつて死滅することを防止で
き、しかも、空気の泡も発生し難くいことから、
卵への悪影響も防止できるという効果を有するも
のである。
As mentioned above, this invention prevents the death of young fish due to water leakage and cracks in the aquarium by making the aquarium an integral structure made of a composite material made of synthetic resin.
In addition, by configuring the fresh water supply valve so that the fresh water supplied from the water injection pipe is discharged horizontally as well as upward, the fresh water can flow almost uniformly over the entire surface of the aquarium. This prevents the fry from concentrating in one place, which prevents the fry from dying due to lack of oxygen, and also makes it difficult for air bubbles to form.
This has the effect of preventing adverse effects on eggs.
