As described above, various internal structures have been proposed for containers for accommodating live aquatic animals. However, a container having an internal structure capable of relieving the stress felt by the housed aquatic animals when a large amount of live aquatic animals is housed has not been known.

Patent Document 5 discloses a vertical partition plate in which 4 to 8 plates are formed radially from the center of the culture cage toward the side surface, and since sea urchins have a habit of gathering at the corners, 8 plates are disclosed. It is stated that a vertical partition plate is used (see pages 4 to 5 of the same document and FIG. 1). The partition plate has an acute angle at the center of the radial shape. However, in a container having such a structure, sea urchins are densely packed in the center of the aquaculture cage, and as a result, there is a problem that the sea urchins tend to feel stress.

That is, the present invention is a container that solves these problems.

With such a configuration, a space is formed on the side surface of the container in which aquatic animals prefer to dive.

The second container of the present invention is a container provided with a plurality of partition plates, wherein the side ends of one partition plate and the side ends of the other partition plates are arranged at an acute angle on the side surface thereof. be. By providing such a configuration, a plurality of spaces in which aquatic animals prefer to dive are formed on the side surface of the container. The plurality of partition plates may be arranged in a zigzag shape when viewed from above in the vertical direction.

The third container of the present invention is a container provided with an opening through which the aquatic animal can pass on the partition plate. With such a configuration, aquatic animals can freely move in the container through the opening, and thus it is possible to avoid crowding in a specific part of the container. In the present invention, when the aquatic animal is a sea urchin, it is preferable that the opening is larger than the shell diameter of the sea urchin. By providing such a configuration, the sea urchin can freely move in the container.

Another container of the present invention is a container in which the opening on the partition plate is not at a position where the partition plate and the bottom surface are in contact with each other. This is because by providing such a configuration, even when the container is tilted, the settled feed is appropriately dispersed on the bottom surface of the container without being biased to a part of the bottom surface of the container.

Another container of the present invention is a container in which the upper end of the partition plate is located below the water surface when the storage space is filled with water. By providing such a configuration, it is possible to eliminate the factor that the suspended matter such as dust stays in the container.

Another container of the present invention is a container provided with a through hole through which water can pass on the bottom surface and / or the side surface thereof, and specifically, a part or all of the container is submerged under the water surface for use. It is a cage and / or a basket.

Another container of the present invention is a container in which the storage space is a tapered space in which the space narrows toward the upper side or the lower side in the vertical direction. By providing such a configuration, a plurality of skeleton portions of the container can be stacked, so that storage and transportation can be performed in a small space.

In the container of the present invention, a space that aquatic animals prefer to dive into is formed on the side surface of the container. The aquatic animals are dispersed on the sides of the container without being biased to a part of the container. Therefore, it is possible to house the aquatic animals without giving stress due to the crowding to the aquatic animals.

A storage space 110 for accommodating aquatic animals is formed in the container main body 102, and opens toward the upper side in the vertical direction.

The container 100 has a square columnar shape, the front surface and the back surface are trapezoidal, and the left and right side surfaces are rectangular. Therefore, the accommodation space 110 is a tapered space in which the space narrows toward the upper side in the vertical direction. Since the aquatic animals feed on the bottom surface when the settling food is fed, there is an advantage that the larger the area of the bottom surface 106, the larger the number of aquatic animals that can be fed at the same time. Further, the point that the accommodation space 110 is tapered is that when not in use, a plurality of skeleton portions 104 with the internal structures such as the bottom surface 106 and the partition plate 112 removed can be stacked, so that storage and transportation can be performed in a space-saving manner. It has the advantage of being possible.

The container shown in FIGS. 3 to 5 is an embodiment provided with a plurality of partition plates 112, but in these embodiments, the side edge of the partition plate 112 and the side edge of the other partition plate 112 on the side surface 108. And are joined, and the partition plates 112 are arranged so as to form an acute angle. On the other hand, in these embodiments, the partition plate 112 and the other partition plate 112 do not intersect. The structure in which the partition plates 112 do not intersect with each other is advantageous in that it is sturdy, hard to break, and easy to manufacture.

Here, the aquatic animal housed in the container body 102 is preferably a sea urchin. As the sea urchin, edible sea urchin is preferably used, and the edible part of the reproductive nest can be enlarged by feeding the sea urchin's favorite food such as compound feed, sea urchin, vegetables, etc. in the container body 102. The uni here are, for example, Kitamurasakiuni (Strongylocentrotus nudus), Ezobafununi (Strongylocentrotus intermedius), Murasakiuni (Heliocidaris crassispina), Bahununi (Hemicentrotus pulcherrimus), Akauuni (Pseudocentrotus). And so on.

In the natural environment, sea urchins prefer to hide in the gaps between rocks to escape foreign enemies. Therefore, since the sea urchin in the container 100 enters the acute-angled space formed by the side surface 108 and the partition plate 112, the sea urchin can be grown in the container body 102 without giving stress to the sea urchin. Further, since the container body 102 is formed with a plurality of acute-angled spaces on the side surface 108 instead of the central portion of the storage space 110, the sea urchins are not densely packed in a part of the container body 102 and are appropriately dispersed. , Does not give excessive stress to sea urchins.

It is preferable that the partition plate 112 can be attached to a sea urchin. The partition plate 112 is composed of a member having a structure having a large number of through holes. Since the through hole provided in the partition plate 12 does not obstruct the passage of water in the container body 102, the resistance of water applied to the entire container body 102 can be reduced. Preferably, as the partition plate 112, a net made of resin molded into a mesh shape can be used.

The through hole on the partition plate 112 is preferably larger than the through hole on the bottom surface 106 and / or the side surface 108 of the container body 102. This is to maintain an environment in which aquatic animals can easily inhabit by smoothing the water flow in the container body 102.

FIG. 6 is a front view of the container main body 102, and the front side surface 108 of the container main body 102 and the partition plate 112 are trapezoidal. The upper edge 120 of the partition plate 112 is preferably below the water surface. This is because when the upper edge 120 of the partition plate 112 is on the water surface, suspended matter such as dust becomes a factor of staying in the container main body 102.

The partition plate 112 is provided with one or more openings 122 through which aquatic animals can pass. When the aquatic animal housed in the container body 102 is a sea urchin, the opening 112 is preferably larger than the shell diameter of the sea urchin. Aquatic animals are free to move within the containment space 110 through the opening 112. Therefore, it is possible to prevent the aquatic animals from congesting in a specific place in the containment space 110, and to appropriately disperse the aquatic animals in the containment space 110.

The opening 122 of the partition plate does not touch the bottom edge 124 of the partition plate 112. That is, the opening 122 is provided at a position not in contact with the bottom surface 106 of the container body 102. The container body 102 floating on the water surface may be tilted due to the influence of waves, but when the opening 122 of the partition plate 112 is provided at a position where it does not contact the bottom surface 106, the settled feed is placed on the bottom surface 106 of the container body 102. It has the advantage that it is easy for aquatic animals to find food because it is dispersed appropriately without being biased to a part.

The partition plate 112 and the bottom surface 106 may be detachable from the container body 102. When the container 102 is not used, a plurality of containers 102 can be stacked after removing the partition plate 112 and the bottom surface 106, so that the container 102 can be stored in a small space.
