[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquaculture apparatus for fish and shellfish, and more particularly to an aquaculture apparatus which can be moved by itself. The aquaculture apparatus of the present invention is particularly effective when used in the open sea, for example, and can be suitably used for aquaculture of high-grade fish such as tuna, ishidai, torafugu, shimaji and pearls.

[0002]

2. Description of the Related Art Conventionally, the cultivation of fish and shellfish is usually carried out by setting up a cultivation facility in a bay or bay.

[0003]

[Problems to be Solved by the Invention] However, it is difficult to evacuate in the event of an obstacle such as a red tide due to such means, and in the vicinity of the coast, natural location conditions and restrictions on fishing rights etc. Therefore, it was difficult to expand the aquaculture business any more. The present invention has been made in view of such circumstances, and an object of the present invention is to provide an aquaculture apparatus that can be moved to an appropriate water area by itself.

[0004]

The present invention has been made to achieve such an object, and the present invention is configured as follows. That is, below the floating body, while arranging a culture room in which a net-like member or other water-permeable members are arranged on the outside, the floating body is provided with a propulsion device and a direction change device, What aquaculture equipment der were movable on their own, the buoyant body is an internal cavity, and finely-tight

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIGS. 1 and 2, the aquaculture apparatus has a boat shape, a float portion 10 as a floating body is arranged on a peripheral portion on the upper surface side, and a culture room 12 is attached below the float portion 10. The float portion 10 is a hollow member, and is finely partitioned inside, so that even if a hole is partially formed, the inundation is limited to a part and the whole buoyancy is not affected. I have. In addition, the float 10 has sufficient strength to allow a person to walk on the upper surface for aquaculture management work. Further, the passage member may be suspended between the float portions 10 on both upper sides of the culture room 12 so as to be able to walk freely. The size and size of each part of the float part 10 are determined so as to generate buoyancy sufficient to support the culture room 12 and other attached facilities.

The culture room 12 is formed by extending a wire mesh 16 as a mesh member outside a frame member 14 forming a skeleton thereof. The number of stacked wire meshes 16, the size of the mesh, and the wires constituting the wire mesh are provided. Is determined in consideration of various conditions such as use conditions. Further, the frame member 14 may further use a reinforcing member in consideration of strength. The inside of the culture room 12 is partitioned into an appropriate number by partition walls (not shown).

The bow portion and the stern portion are each constructed so as not to be submerged, and generate buoyancy. An engine (not shown) is mounted on the stern, and the aquaculture device can be moved forward or backward by rotating the screw 18 as a propulsion device forward or backward. 20 is a rudder as a direction changing device. Auxiliary screws are provided on both sides of the screw 18 at a predetermined angle so that the stern can be moved to the right or left while the forward movement is stopped. These operations can be performed in the steering room 22. A ballast tank (not shown) is provided at the bottom of the bow and stern to maintain the stability of the aquaculture apparatus itself. In addition, it is also possible to provide a ballast tank at the bottom of the culture room 12.

In the embodiment constructed as described above, the propulsion device and the direction change device are used to move to an appropriate water area, for example, the open sea outside the fishing right, and anchor to carry out aquaculture there, It is possible to evacuate to the bay in order to avoid such situations, or to quickly evacuate to another water area if a red tide or the like occurs.

In the above embodiment, the wire mesh is provided on both sides and the bottom surface of the culture room 12, but instead, a plate-like member may be provided on the bottom surface or both side surfaces, and a wire hole may be provided with a large hole in some places. According to the above, the outer surface of the wire mesh may be covered with another plate-shaped member so that it can be opened and closed by an operation from the inside. It reduces fluid resistance when aquaculture equipment is navigating, prevents damage caused by assaults such as sharks, reduces the attachment of marine organisms such as shellfish to the bottom outer surface, and facilitates its removal. And so on. In addition, it is arranged in a state where the net is submerged at the bottom of the culture room 12,
By raising the net, the cultured fish may be landed. Further, a plastic net or a net made of other materials may be used instead of the wire net 16 as a member to be attached to the culture room 12, and a water-permeable punching plate or the like having many holes other than the net may be used. May be used. Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment.
It goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.

[0010]

Since the present invention is configured as described above, the following effects can be obtained. According to the aquaculture device of the present invention, since it has a propulsion device and a direction change device, it can be moved or navigated by itself, and it is possible to perform aquaculture in waters beyond the fishing right or in waters abroad. Obstacles such as typhoons and red tide can be avoided immediately. In addition, unlike towing, it can move on its own, making it easy to turn around, passing through relatively narrow places,
It can be used in narrow places.
