Description

  The present invention relates to a livestock farm for raising fishery products, in particular, a root resource.

  In recent years, on the coasts of Japan, a phenomenon called “mochi-yaki” has become frequent, in which kombu, wakame and many other types of seaweeds are reduced and become barren. Firewood burning not only lowers the yield of high-value-added radish resources such as abalone, tocobushi, sazae, sea urchin, and lobster, but also causes a decline in quality such as content and taste.

  On the other hand, there is still a high demand for high-value-added root resources, and it is difficult to meet the demand only with the conventional supply method of capturing natural products. Has been done. In general, aquaculture means growing fish and shellfish from hatching eggs, and livestock raising means growing the captured fish and shellfish for a certain period. In this specification, all cases are expressed as animal husbandry.

  In addition to onshore farming where the fish roots are cultivated from egg hatching or from larvae to adults in artificial water tanks, or grown to a certain size and then released to fishing grounds, In addition, there are livestock farming using fish reefs (for example, Patent Document 1) for forming a favorable growth environment, underwater livestock farming using a cage for livestock farming, and the like.

  Underwater animal husbandry is superior to land animal husbandry in that it does not require special labor to secure seawater, and it is superior to animal husbandry using fish reefs in that it can protect roots resources from foreign enemies, There may be challenges in the difficulty of the method of feeding bait resources.

  For example, in a sea urchin and abalone breeding facility disclosed in Patent Document 2, in order to install a facility for ensuring a growth environment in the sea, a person must submerge and perform a feeding operation. Moreover, the underwater sacrifice feeding method disclosed in Patent Document 3 requires a feeding device having a special tank and a valve for supplying food to the sacrifice installed in the water.

  In livestock farming using ginger, food is often dropped from the top of the ginger to the sea surface, but when feeding with ginger that gathers the root resources with individual differences in size etc. in one place, There is a difference in the degree of growth between them, and the size of the harvest varies, which may affect the individual price and thus the total sales.

  In addition, in an example of a site where sea urchins are actually bred, bred animals in which a large amount of sea urchins are placed in a cylindrical cage having partitions (for example, Non-Patent Document 1) are used by a plurality of workers. The complicated operation | work of pulling up a cylindrical cage and feeding for every division further divided by the partition is required.

<Livestock room>
As long as it has a structure that can secure a space for raising fishery products and allow the necessary water to enter and exit, the animal husbandry room has no particular restrictions on the shape, but it is like shellfish, sea urchin and other root resources or sea cucumbers. It is preferable that the chamber has a bottom surface serving as a scaffold for seafood that does not swim underwater. The shape of the breeding room may be a prism, a cylinder, a truncated pyramid, a truncated cone, or the like. 1-3, the rectangular breeding room 1 which is a kind of prism is illustrated.

  The animal husbandry room may be made of a metal net, a plate having a slit, or a metal, plastic or rubber frame and a net stretched on the frame. In particular, those made from a suitable frame and a fine mesh stretched on the frame are preferable. For example, there is a breeding room that is produced by forming a fine mesh on a rectangular frame formed by welding a thin stainless steel pipe.

  Livestock rooms do not have to have mesh or slits on all sides. For example, in order to prevent escape of seafood and food leakage, and to provide a good scaffold for sea urchins, sea cucumbers, etc., the bottom of the animal husbandry room may be made of a member having no mesh or slits.

  There are no particular restrictions on the size of the animal husbandry room, but the size is such that it can be lifted by manpower or a simple winch from the top of a ship, for example, length x width x height 1 m to 3 m x 1 m to 3 m It is preferable that it is about 0.5m-1m.

  The livestock room is provided with a hole (reference numeral 3 in FIG. 1) for connecting a feeding path described later. The upper part of the breeding room means, for example, a ceiling surface when the shape of the breeding room is a prism, a cylinder, a truncated pyramid, a truncated cone, or the like, and also means a surface or a part corresponding to the other shape. . Moreover, the hole should just have a shape and a magnitude | size equivalent to the shape and magnitude | size of the edge part connected with the breeding room of a feeding path.

  The livestock room preferably has a partition wall that partitions the interior of the livestock room and is perpendicular to the bottom surface, and in particular, a partition wall that extends from the center of the livestock room to the side surface. FIG. 1 illustrates four partition walls 5 that respectively extend from the center of the animal husbandry room to four side surfaces.

  If fish and shellfish that have physique differences among individuals are bred together in one section, individuals who are physically disadvantaged will not be able to secure enough food, and the individual may become poorly grown and the product value may decline Therefore, it is desirable to divide the individuals into groups according to their physiques and feed each group. The partition in this invention is provided in order to form the division for raising such a group for every group in the inside of a breeding room. In addition, the partition wall has an effect of providing more scaffolding (surface of the partition wall) with respect to the root resources to be cultivated.

  The partition wall may be made of a member that does not have mesh or slits, but it has an appropriate size so as not to cause unnecessary resistance when water enters and exits the breeding room and to prevent mixing of seafood with different physiques. It is preferable to be made from a member having a mesh or slit. As the partition wall, for example, four square frames connected in a cross shape are manufactured by welding thin stainless steel pipes, and a fine mesh is stretched around the frame.

  Although there is no restriction | limiting in particular in the number of partition walls, What is necessary is just about 1-6 in general. The end of the partition wall may be in contact with or fixed to the side wall of the breeding room, but is preferably separated from the side wall of the breeding room with a gap that allows seafood to pass through. FIG. 1 illustrates a partition wall separated from the side wall of the animal husbandry room. Moreover, although the partition walls shown in FIG. 1 are connected to each other at the central portion, they may be separated at an appropriate interval without contacting each other. That is, when two or more partitions are grounded, one end thereof does not need to be in contact with the center of the breeding room. For example, the seafood may be provided independently of each other with a movable distance.

  The animal husbandry room may have at least one hole for collecting seafood, preferably a hole with an openable / closable lid. The holes and lids may preferably be the bottom and one side or the entire ceiling surface of the animal husbandry room, but the holes and lids may be located at positions where they are in contact with the bottom surface at a part of the animal husbandry room bottom wall or a part of the animal husbandry room side wall. It is preferable to provide small holes. The lid may be removable or hinged.

  The lid is closed during breeding and is opened when raising the breeding room from the water and collecting the seafood. If there is a gap that allows seafood to pass through between the end of the partition wall and the side wall described above, the seafood is gathered through the gap in a holed place by tilting or shaking the breeding room Therefore, seafood can be collected more efficiently. For example, as shown in FIG. 4, the hole may be provided outside the animal husbandry room with a net for collecting seafood as a lid.

<Feeding path>
The animal husbandry tool of the present invention includes a feeding path having a feed inlet provided to be located above the water surface or above the water surface, which is connected to the upper part of the animal husbandry room. That is, one end of the feeding path in the present invention is a feed inlet provided so as to be positioned above the water surface or the water surface, and the other end is connected to the upper part of the breeding room. The connection between the breeding room and the feeding path may be performed by any means such as clip fastening, fitting, sliding attachment, and ligation. Moreover, you may connect by shape | molding integrally with a breeding room. Moreover, there is no special restriction | limiting in the shape of a feeding path, as long as it does not prevent that a food falls naturally, but what is necessary is just a cylinder, a prism, etc.

  The feeding channel has a feed inlet at the surface of the water or above the surface of the water, so if a bait prepared to sink by its own weight is introduced into the feed inlet from above the ship, the feed can be delivered to the animal husbandry room through the feeding channel. it can. Therefore, there is no need for a person to dive and deliver food to the animal husbandry room, to prepare a special device or tool for supplying food to the underwater animal animal room, or to raise the animal animal room every time food is fed. In order to provide the feed inlet at the water surface or above the water surface, an appropriate float may be attached around or slightly below the feed inlet, or the feed inlet may be suspended from the water at a predetermined position.

  For example, as illustrated in FIG. 2, the feeding path may have a certain thickness from the feed inlet to the animal husbandry room. The shape when the feeding path in this case is viewed from the side is a columnar shape as indicated by reference numeral 8-a in FIG. 3A. Such a feeding channel may be, for example, a straight or bellows-like pipe or hose.

  Further, the feeding path may be thicker continuously or discontinuously from the feed inlet to the animal husbandry room. The shape when the feeding path that becomes continuously thick is viewed from the side becomes a trapezoid as indicated by reference numeral 8-b in FIG. 3B.

  A feeding path that increases continuously or discontinuously from the feed inlet to the animal husbandry room allows the input food to drift and diffuse within the thickness of the feeding path before reaching the animal husbandry room. It is more advantageous than a feeding path in which the thickness is constant from the feed inlet to the breeding room in that feed can be supplied to a wider range of the breeding room. 3b is connected so that it may overlap over the whole ceiling surface of a breeding room, and can supply a food evenly to the whole breeding room.

  Examples of feeding paths that have a cross-sectional area that extends continuously or discontinuously from the feed inlet to the animal husbandry room include a plurality of pipes provided at intervals such as sliding pipes or fishing gear called scalli And those having a stretchable structure, such as those produced by stretching a net on the frame. In particular, it is preferable that a plurality of frames provided at intervals are made by stretching a net (hereinafter referred to as a net feeding path). Feeding path 8-b in FIG. 3b is an example of a net feeding path.

  The net feeding path naturally collapses and shrinks when there is no floating or support, so it does not get in the way when raising the breeding room, and easily change the crossing area of the feeding path by changing the size of the frame Has the advantage of being able to. Furthermore, the connection with the animal husbandry room can be easily performed, and the possibility of damage due to the swell of water can be reduced.

  As shown in FIG. 5, the animal husbandry tool of the present invention is suspended in water by attaching an appropriate float 11 and weight 13, and is moored by being tied to a ship, a fence or a support using a rope 12 or the like. You may use it, or you may use it in the state which grounded the breeding room to the bottom of the water. Moreover, although not shown in figure, you may connect with a water bottom by the anchor etc. via the rope 12 or the weight 13. FIG. Moreover, you may arrange | position and use this for several animal breeding rooms in the horizontal direction.

  The livestock farming tool of the present invention may be provided with various auxiliary tools for enhancing convenience during use in addition to the above-described configurations as necessary.

  The animal husbandry tool of the present invention is suitable for aquatic resources having high economic value such as abalone, shrimp, turban shell, sea urchin, lobster, especially sea urchin, but is not limited thereto, sea cucumber, crab and other It may be used for raising seafood.

  The livestock raising tool of the present invention can be suitably used for raising fishery products, in particular, root stock resources, particularly sea urchins. In particular, it is possible to easily and evenly feed seafood in the sea, and it is possible to increase the proportion of individuals with high commercial value by suppressing the difference in growth and size of seafood at harvest, etc. it can.
