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 is a stainless steel bottom screen stretched on the bottom side of the hatching chamber B, 7 is a hatching tray stretched on the top side at a desired distance from the bottom screen 6, and the hatching tray 7 and the bottom are connected. Between the nets 6 and 6, net rings 8 made of polyethylene nets formed into cylindrical shapes are randomly sunk. Reference numeral 9 denotes a net for preventing the fry from flowing out, which is placed on the side of the stepped portion 1c of the hatching chamber B, and is made of stainless steel.

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.

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.

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.

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. .

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 present invention solves the above-mentioned problems and provides a flotation tank for fish farming suitable for hatching eggs and raising young fish.The purpose of this invention is to make the tank integrally constructed of a composite material made of synthetic resin, and The lower end of a water injection pipe and a fresh water supply valve connected to the water injection pipe are buried in the bottom of the water tank, and the fresh water supplied from the water injection pipe is horizontally discharged into the upper end opening of the fresh water supply valve. An umbrella-shaped cover plate is attached with a large number of holes opening at intervals from the opening and also discharging water upward.

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.

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.

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.

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

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.

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.

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.
