The front portion of the first aquarium 2A and the rear portion of the second aquarium 2B are in a communicating state by the return water passage 5A of the partition wall 5. Moreover, the area of the 1st aquarium 2A and the 2nd fish tank 2B is collectively called a breeding part.

The rear portion of the second fish tank 2B is provided with a flow device 3 that fills the groove width. The flow device 3 ejects bubbles 8 from below in the front and rear barrier nets 3E and 3D, so that the water directly above rises and the water flow occurs. .

A plurality of sedimentation basins 4A, 4A occupying the groove width are juxtaposed in the rear portion of the rear barrier mesh 3D. The purification unit 4F is divided by the barrier nets 3E and 9 as the boundary, wherein the barrier nets 3E and 9 are arranged in the same row. The rear part of the first fish tank 2A and the front part of the second fish tank 2B.

When the flow device 3 is operated, the rearing water generates a flat water flow in the entire width of the second fish tank 2B, and the flowing rearing water passes through the purification device 4 of the purification unit 4F from the second fish tank 2B, and enters the first fish tank 2A. Go further to the 2nd fish tank 2B and cycle through the whole.

The water depth of the rearing water is, for example, about 150 cm, but can be adjusted to increase or decrease depending on the size or quantity of the fish.

The aquaculture apparatus 1 shown in Fig. 1 has, for example, a length of 55 m and a width of 11 m, and the first fish tank 2A and the second fish tank 2B which are arranged side by side are separated by a partition wall 5.

A part of the partition wall 5 protrudes from the purification portion 4F and is in contact with the wall surface of the purification device 4, and a part thereof is formed as a water return passage 5A having an openable and closable opening and closing door 5B so as not to pass through the purification device 4. Feed water 5B reflux.

The purification device 4 in the purification unit 4F having a length of, for example, approximately 17 m is disposed so as to be sandwiched between the first fish tank 2A and the second fish tank 2B.

Like the longitudinal section of the line II-II of Fig. 1 shown in Fig. 2, the hoisting device 3 is at the rear end portion of the bottom of the groove of the second fishpond 2B, and the groove width direction is formed in the plan view shown in Fig. 1. (left-right direction in Fig. 1) a long shape, and for example, a deep groove 3A exceeding 2 m, and in the middle of the front and rear of the groove 3A, in a manner from the water surface to the vicinity of the bottom of the groove 3A The barrier wall 3B of the water before and after the barrier is provided, and the partition wall 3C is divided into a plurality of divisions in the groove width direction (5 divisions in FIG. 1), whereby the water flow is efficiently generated. The partition wall 3C may not be formed if it is not necessary.

Thereby, as shown in FIG. 2, the rearing of the first fishpond 2A The water enters the groove 3A having a long groove width direction, and passes under the barrier rib 3B to reach above the front portion of the groove 3A, and enters the second fish tank 2B.

As shown in Fig. 2, the groove bottom 2C which is the upper surface of the edge before and after the groove 3A is provided with a pair of front and rear barrier nets 3D and 3E which restrict the reciprocation of the fish to the water.

As shown in Fig. 1 and Fig. 2, an air supply pipe 7 extending from the air supply device 6 is disposed in front of the lower edge of the barrier wall 3B of the groove 3A, and an air discharge port 7A that is open upward is provided at an upper portion thereof. As long as the air vents 7A can discharge the air bubbles 8, the number or shape thereof is not limited.

When the compressed air is sent from the air supply device 6, the air bubbles 8 rise violently from the air discharge port 7A, and the water is raised directly above the water.

The brooding water is moved horizontally in front of the second aquarium 2B to generate a water flow, and passes through the purification device 4 of the purification unit 4F, and enters the first aquarium 2A, and circulates toward the entire second fish tank 2B.

In Fig. 2, the rearing water of the groove 3A is moved to the second fish tank 2B by the hoisting device 3, whereby the rearing water of the first fish tank 2A is sucked to the bottom of the groove 3A and goes to the barrier wall 3B. The front moves and flows, and the rearing water becomes a whole.

Thereby, the feed water of the entire aquaculture tanks 2A and 2B can be efficiently circulated without separately providing a pump for circulation. The reared fish maintains healthy growth by continuously moving toward the upstream. However, if the flow rate is too fast, the aquatic product will be fatigued, so it is necessary to set the appropriate flow rate with the fish.

Further, by the air bubbles 8 ejected from the air discharge port 7A in the hoisting device 3, oxygen in the air can be made to enter the water, and the stirring of the water by the water truck or the like can be omitted.

As shown in FIG. 1, a plurality of sedimentation basins 4A, 4A which are square in plan view are adjacent to the upstream side of the barrier nets 3D, 3E and are formed side by side in the width direction of the aquarium 2. As shown in Fig. 4, the sedimentation basin 4A is formed in a funnel shape deep in the bottom of the fish tank 2. The bottom of the bottom of the sedimentation basin 4A is formed with a drain hole 4B, and a plug 4C is connected, and the drain hole 4B is connected to the bottom. Sewer not shown.

The residual bait, fish manure, and the like flow into the sedimentation basin 4A.

The opening and closing doors 2F and 2F are provided on the water passage of the purification device 4 that has reached the purification unit 4F. In these opening and closing doors 2F and 2F, a filter for collecting fine dust is occasionally mounted.

In this way, while the feed water is allowed to flow through the upper portion of the sedimentation basin 4A, the weight of the residual bait or fish manure is precipitated in the sedimentation basin 4A, and the ammonia is filtered out in the next biofilm treatment device 4D. The organic matter and the fine particles of the sedimentation pot 4A can be efficiently filtered even if the circulation of the rearing water is, for example, 200 m ³ /hr. By closing the opening and closing doors 2F, 2F, cleaning of the purification device 4 can be facilitated.

The biofilm processing apparatus 4D is provided with a filter (not shown) that is stretched and provided in a lower portion of the tank. The filter screen is densely packed with a plurality of small small filter members (not shown), and the bubbles sent from the bottom pass through the respective filters. It rises between the filter elements. The bacteria multiply and decompose on the residual bait, fish manure or the like attached to the filter. The filtered feed water is circulated from the bottom of the tank to the first aquarium 2A through the upward route.

The fresh water supply pump 10 shown in Fig. 1 is supplied to the first aquarium tank 2A through the clean water pipe 10A. Thereby, the stocking density of the aquatic product is, for example, a maximum of 100 kg of aquatic product per ton of water.

Further, when the oxygen concentration sensor 12 detects that the oxygen content in the water becomes 90% or less of oxygen saturation, the automatic controller 13 automatically operates the valve 11B of the oxygen tank 11 and passes through the oxygen tube 11A to the fish tank 2. The feed water supplies oxygen to become saturated.

In this case, the oxygen tube 11A can be coupled to the air supply tube 7 and discharged together with the air bubbles 8 toward the rearing water. This oxygen supply is important as a natural disaster and other emergency.

In addition to, for example, rainbow trout, squid, and the like, the aquatic products raised in the aquaculture apparatus 1 are also suitable for the aquatic products suitable for the place, but are not specific thereto. In addition to fresh water, the rearing water uses seawater or water containing salt close to seawater.

In the vicinity of the aquarium 2, an illumination lamp that can illuminate the water surface may be provided to assist in extending the sunshine time in autumn and winter, or to sterilize with a germicidal lamp. In the snowy area, a snow-proof roof is installed. In the place where there is no roof, it is to tighten the bird net or the shade screen of Xiayang above the fish tank 2.

Figure 5 is a plan view showing another embodiment of the aquaculture apparatus 1. The same components as those in the previous example are denoted by the same reference numerals and the description will be omitted. In this embodiment, the purification device 4 is disposed away from the fishpond 2 because of the land area relationship.

In other words, the water passage 2D is extended from the second fish tank 2B, the purification unit 4F is disposed in front of the second fish tank 2B, and the purification device 4 is disposed, and the water passage 2E connected to the self-purification device 4 is connected to the first fish tank 2A. Opening and closing doors 2F and 2F are disposed in each of the water passages 2D and 2E. Thereby, the opening and closing door 2F of the water passages 2D and 2E can be closed, and the cleaning of the purification device 4 can be facilitated.

Further, in the water passage 2D on the front side of the purification device 4 or the water passage 2E on the rear side, the same device as the hoisting device 3 may be disposed. In the above-mentioned aquaculture apparatus 1 , a plurality of places having a large land area are arranged in parallel in the state of FIG. 1 .
