2. Description of the Related Art Shellfish culture has been practiced not only in Japan but also in the world. For example, aqua and shellfish are cultivated to collect pearls. As a natural method, aquaculture is the production of juvenile mussels in seawater to grow them. For this reason, before that, larvae were put in a large box-shaped or cage-shaped one in a moor, tied in a hanging rope and put in the sea, and one end of the hanging rope was tied in a floating raft. Or place a net bag in a suitable place of the hanging rope, put larvae in the net and cultivate it in the sea, or even hook one end of a thin wire. The young oysters were locked on the hanging rope by a method such as hooking young oysters on it and binding the other to the hanging rope. Since shellfish must be cultivated in the sea for about four years, other shells and seaweed adhere to the outer wall of box-shaped or cage-shaped shells, and with fine wires, they are oxidized by salt and damaged. Was terrible. Therefore, there was a risk that oxygen and nutrients would not reach the juveniles sufficiently or that the clams would fall to the seabed.

[0003]

[Problems to be solved] According to the conventional technology, the young mussels are obstructed by absorption of oxygen and nutrients by seaweeds and other mussels, resulting in a large amount of dead mussels or insufficiently matured mussels. There is also a risk that the metal will corrode and damage due to the oxidation of the salt in the seawater, causing the shell to come off from the wire even if the young shell is hooked down using a thin wire. there were. Therefore, you can easily and easily lock the young shellfish,
In addition, the locked young oysters can be easily and easily locked on the hanging rope to keep them safely for a long time Oxygen and nutrients are spread evenly, preventing the shells from falling and coming off, and the hanging of the aquaculture shells that can be used easily It is intended to provide a down pin.

[0004]

Therefore, in order to prevent the conventional defects and to easily and easily lock the juvenile molluscs to the hanging rope, in the hanging pin composed of the stem core portion, the locking piece and the protruding piece, Sharp protrusions are provided symmetrically in an appropriate number of places on both ends of the trunk, and a plurality of locking pieces having holes are provided in the center of the trunk in a convenient manner. It is solved by using a hanging pin featuring The present invention seeks to provide such a hanging pin not previously found.
