Abstract

PURPOSE:To enable safe and efficient culture of juvenile shells of bivalves such as oyster, pearl oyster and scallop. CONSTITUTION:A juvenile shell is attached to a dangling pin passed through a suspension cord. The attached juvenile shells are put into the sea together with the suspension cord to carry out the cultivation of juvenile shells. The introduction of the suspension cord into the sea is carried out by suspending the cord in vertical direction or by extending the cord in horizontal direction.

2. Description of the Related Art Fishery resources have been widely used as human food sources not only in Japan but also in the world. Therefore, the resources are being reduced due to overfishing and deprivation. Therefore, in recent years, the time has passed from overfishing of fishery resources to the era of aquaculture. In particular, aquaculture of shellfish is being carried out quickly not only as a food resource but also for the purpose of securing accessories. These traditional shellfish cultures are generally done by simply putting juveniles in a large cage,
It was a method of only suspending in the sea, or attaching a small net bag at any place of the hanging rope, putting a young shell in it, and suspending it in the sea for aquaculture. In addition, it was a method of hanging a juvenile using a thin wire and attaching it to a hanging rope to cultivate it in the sea. However, it takes at least four years to cultivate juvenile shellfish in the sea and grow them, and during that time, these net bags, baskets or thin wires are placed in the salty sea. is there. As a result, seaweed adhered to the net bags and baskets, and the thin wires were often oxidized by salt, becoming brittle, and broken. Furthermore, the ocean current is flowing at a considerably high speed in the sea, and this force may cause damage to the aquaculture basket, the aquaculture net bag, or the like, and the fish may be washed away.

[Problems to be solved] In the conventional aquaculture method, since the aquaculture is left in the sea for a long time, seaweed adheres to the aquaculture basket and the aquaculture net bag. Among them, shellfish that cannot be commercialized due to suffocation death or nutritional deficiency, or due to the speed of the ocean current or the intensity of the waves, the hanging rope cuts the net bag or the binding part of the basket. There was also the drawback that the shells would be submerged in the sea, or the wire would break due to salt corrosion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 is a state diagram in which the hanging rope according to the method of the present invention is hung, and FIG. 2 is a state diagram in which the hanging rope according to the method of the present invention is stretched sideways, and FIG.
4 is a partially expanded view of FIG. 1, and FIG. 4 is a partially expanded view of FIG. Most shellfish farms are located in coastal bays. Still, the water depth varies and the water depth is 100.
Some are within m and some are at a depth of about 200 m. Therefore, Fig. 1 and Fig. 3 show that when the water depth is 100 m or more,
This is the case when shellfish is cultivated in a place within 0 m.
(1) is an object that floats on seawater, such as a floating raft. This is usually made by bundling timber or the like, or by connecting it to a drum tube or the like, but a specially made one may also be used. (2) and (2 ') are hanging ropes. The hanging ropes (2) and (2 ′) are tied to the raft (1) with one end fixed to the required number. The hanging rope (2)
A weight (6) is attached to the other end of (2 ') and put in the sea. The material of the hanging ropes (2) and (2 ′) may be convenient, but synthetic resin fiber material is most convenient. (3) is a hanging pin. The hanging pin (3) can be made of various materials, but the most resistant material is the synthetic resin material, which is the most resistant and elastic. The hanging pin can be made in various shapes. (4) is young shellfish. The young oyster (4) is not that big,
It grows bigger and heavier as it grows. The types of juveniles are bivalves such as scallops, oysters, and oysters. This juvenile shell (4) hangs a rope (2) (2 ')
To hang it on, do the following: First, hang the hanging rope (2) (2 ') at the appropriate spot on the hanging rope (3).
Are pierced at regular intervals or at arbitrary intervals. Since it is the hanging rope (2) (2 ') of 100 m or more, many hanging pins (3) can be attached. Various structures can be made for the structure of the hanging pin (3). Here, description will be given based on the hanging pin (3) having the locking piece and the protruding piece. When the hanging pin (3) is attached to the hanging rope (2) (2 '), the hanging pin (3) is fixed to the hanging rope (2) (2') by the protruding piece of the hanging pin. To do. The locking piece of the hanging pin (3) thus fixed is provided in the ear portion of the juvenile shellfish (4) and penetrated into the hole of the ear portion. By doing so, the juveniles (4) enter the inside of the locking piece, the locking piece functions as a stopper, and does not easily come off from the hanging pin (3). In this embodiment, since the locking pieces are provided at both ends of the hanging pin (3), the juveniles (4) can be locked and hung down on each of them. In this way, the juvenile mussels (4) are successively locked to the hanging ropes (2) (2 '). Suspended rope (2) to which these juveniles (4) are locked
One end of (2 ') is fixed to the floating raft (1), the other end is attached with a weight (6) and put in the sea, and the hanging rope (2)
The larvae (4) are placed in the sea and cultivated by making (2 ') vertical to the seabed. In another embodiment, the hanging ropes (2) and (2 ') are not used in the vertical direction but are used in the horizontal direction to cultivate juveniles in the sea. That is the case shown in FIGS. In this case, the water depth is 10
It is suitable for cultivating shellfish in a bay within 0 m. Since the hanging ropes (2) and (2 ′) are stretched in the lateral direction, the hanging pins (3) having different shapes are used. Also in this embodiment, the hanging pin (3) is composed of a locking piece and a projecting piece.
It is better to use the one that has a forked core. In this case, one locking piece of the hanging pin (3) is passed through the hanging rope (2) (2 '). By doing so, the hanging pin (3) becomes the hanging rope (2).
Stick to (2 '). After that, to the protruding piece of the stem core formed on the fork of the hanging pin (3), the young shell (4)
A hole is provided in the ear portion of each of the holes, and each of the holes penetrates. The bifurcated stem core is provided with projection pieces of an appropriate number of feces, so when the juvenile shellfish (4) is penetrated, the projection pieces act as a stopper function, so the juvenile shellfish is easily removed. Does not fall or fall. In this way, after a suitable number of juveniles have been locked to the hanging pin (3), which is formed on the bifurcated trunk, the other ends of the bifurcated trunk are respectively suspended on the hanging ropes (2) (2). '). In this way, the hanging rope (2)
The young shell (4) is locked to (2 '). Hanging rope (2)
Even if the length of (2 ') is 100 m or more, the juvenile (4) can be appropriately locked depending on the length. In this way, the hanging rope with the young shell (4) attached,
One end is fixed to the hanging rope (5) hanging from the floating raft (1), and the other end is fixed to the hanging rope (5) hanging from the other floating raft (1). Then put in the sea. This hanging rope (5) has a floating raft (1) at one end
And a weight (6) is attached to the other end. By putting the larvae in the sea by such a method, the larvae can be held at regular intervals, the weight can be dispersed to some extent, and the larvae are evenly exposed to seawater / current. It also becomes.

By the method as described above, oxygen and nutrients in the sea are sufficiently distributed to the larvae, the oxygen and nutrients are not blocked by the seaweed, and the hanging pins are attached. It is easier and cheaper to create, and because it retains its strength, it will not easily fall even when larvae grow, and it will not be oxidized and damaged by the salt content of seawater. It is possible to provide a growing shellfish economically and safely.
