Description

The present invention relates to a pearl nucleus insertion method, a pearl nucleus insertion tool, and a pearl nucleus that are used when a pearl nucleus is inserted into an abalone in order to form an abalone pearl in a cultured abalone.

Abalone is a high-quality food with high commercial value and has been cultivated by many fishermen since ancient times. However, abalone farming takes a long time to grow abalone, has poor productivity, and suffers from poaching, so fishermen's income does not increase and fishermen's lives do not improve. Therefore, there is a demand for measures to increase the income of fishers who are abalone farming and improve the lives of fishers.

Abalone can be made not only to make high-quality ingredients, but also to make abalone pearls that can be sold as jewelery inside the shell. If the cultured abalone can produce high-quality foods and abalone pearls, it can increase the income of fishers who are abalone farming and improve the lives of fishers. Therefore, it is attempted to make the abalone pearls produced by the cultured abalone.

Since the pearl layer inside the abalone shell tends to be brighter in the area near the crest than in other areas, the abalone pearl made in this area is particularly valuable as a jewelry. If abalone pearls can be made in such areas, the value of the abalone pearls made will increase further, and the fishermen's income from abalone farming will increase further, and the fishermen's lives can be further improved. .

Therefore, various methods have been proposed and implemented for forming abalone pearls with high value as jewelry by installing or inserting pearl nuclei in the vicinity of the crests inside the shells of cultured abalone.

For example, a hole is made from the front side in the area near the screw top of the abalone shell, a protrusion is inserted into the hole from the front side to form a protrusion inside the shell, and a pearl component is wound around this protrusion to form a pearl. A method has been proposed and implemented.

However, this method is cultivated because the abalone's internal organs are damaged when a hole is made in the shell, and the abalone is susceptible to infection, and the abalone is subjected to various burdens by fixing the projections. There was a problem that the death rate of abalone increased and it was impossible to expect an increase in income from abalone farming.

If you try to form a protrusion by carefully drilling a hole in the shell of the abalone so as not to damage the abalone's internal organs, the workability of the formation of the protrusion will be significantly reduced, and the production cost of the abalone pearl will increase. There was a problem that it was impossible to expect an increase in income from aquaculture.

In addition, for example, a method has been proposed and implemented in which a part of the binding portion of the abalone mantle is incised in the vicinity of this region, and the pearl nucleus is inserted into this region with tweezers through a gap formed by the incision. .

However, this method imposes a burden on abalone through incision of the mantle, and abalone is susceptible to infection, so the mortality rate of abalone cultivated is high, and an increase in income from abalone culture is expected There was a problem that it was impossible.

Therefore, a new proposal of a pearl nucleus insertion method or a pearl nucleus insertion tool that does not increase the death rate of abalone cultivated has been desired.

In the nucleus insertion step, the insertion port of the insertion tube A pearl nucleus is inserted into the pearl nucleus, and the pearl nucleus is pushed to the discharge port with a plunger and discharged from the discharge port.

Here, examples of the abalone include black abalone, mega abalone, madaka abalone, ezo abalone, tocobushi, and snail, but other snails can be used as long as they are capable of forming a pearl. May be. In addition, the vicinity region of the crest portion means a region (region where there is no mantle and the internal organs are in direct contact with the shell) reaching a portion slightly away from the crest portion toward the priming hole. The insertion tube and the pearl nucleus are as described later.

Further, the pearl nucleus insertion tool according to the present invention comprises a flat, substantially straw-shaped insertion cylinder, and a plunger that moves the pearl nucleus inserted in the insertion cylinder by pushing from behind, the insertion cylinder comprising: It has an insertion port for inserting a pearl nucleus on the base end side, and has a discharge port for discharging the pearl nucleus on the distal end side.

Here, as the insertion tube, it is possible to use a tube formed by rounding a plastic sheet with a streak in the longitudinal direction. As the discharge port of the insertion tube, an opening formed by cutting off the distal end of the insertion tube at a substantially right angle may be used as the discharge port as it is. It may be provided. In the case where the discharge port is provided on the side portion on the screw top side of the distal end of the insertion tube, the opening at the distal end of the insertion tube is closed with a closing plate. It is preferable that the closing plate is provided in an inclined state toward the discharge port so that the pearl nucleus pressed against the closing plate is pushed out toward the discharge port.

Moreover, the pearl nucleus which concerns on this invention consists of a pearl nucleus part and the flange part provided in the circumference | surroundings of this pearl nucleus part, It is characterized by the above-mentioned.

Here, an abalone shell can be used as a material for forming the pearl nucleus. The pearl nucleus is flat and can have any shape. For example, a shape such as a substantially hemispherical shape, a heart shape, or a drop (tears shape) can be selected. The flange portion may have any shape as long as it protrudes from the pearl nucleus portion. For example, a circular shape, a polygonal shape, a shape similar to the shape of the pearl nucleus portion, or the like can be selected. The flange portion may be provided integrally with the pearl nucleus portion or may be provided separately from the pearl nucleus portion. When the flange portion is provided separately from the pearl nucleus portion, a pedestal component having a larger planar shape than the pearl nucleus portion is made, and the pearl nucleus portion is attached to the center portion of the pedestal component by bonding or fitting, A portion that protrudes around the core portion can be used as the flange portion.

The abalone mantle is only linearly bound to the inner surface of the shell around the edge of the shell and the pillar, and the region from the head side to the vicinity of the crest is not bound to the inner surface of the shell. Therefore, the insertion tube inserted between the shell and the mantle from the head side enters the gap between the shell and the mantle without damaging the abalone's internal organs and mantle, and is inserted as far as the vicinity of the screw top. . If the pearl nucleus is inserted into the insertion tube from the insertion port of the insertion tube in this state, the pearl nucleus is pushed by the plunger and discharged from the discharge port of the insertion tube, the pearl nucleus is inserted in the vicinity of the screw top portion. .

Therefore, according to the pearl nucleus insertion method and the pearl nucleus insertion tool of the present invention, the pearl nucleus can be inserted into the region near the crest of the abalone shell without damaging the abalone internal organs or mantle. Therefore, the mortality rate of abalone cultivated does not increase, and a large number of abalone pearls can be produced in the abalone. Therefore, there is an advantage that the income of fishermen can be increased by abalone culturing.

Further, according to the pearl nucleus insertion method and the pearl nucleus insertion tool of the present invention, the pearl nucleus can be easily inserted into the vicinity of the screw crest inside the abalone shell, so that the pearl nucleus is inserted into the abalone shell. There is an advantage that a large amount of abalone can be cultivated in order to make the abalone pearls to be produced, and the abalone culture can increase the income of fishermen.

Further, according to the pearl nucleus of the present invention, when the pearl nucleus is fixed to the edge of the shell, the flange is always fixed to the edge of the shell, and the pearl is not fixed to the edge of the shell. There is an advantage that an abalone pearl with a beautiful curvature without chipping or distortion can always be obtained.

Further, in the pearl nucleus insertion tool of the present invention, if the opening at the tip of the pearl nucleus insertion tool is directed toward the abalone screw crest, the pearl nucleus is pushed out to the screw crest side, and on the screw crest side. Since there is a space, the pearl nucleus pushed out first can move to the side of the crest without staying even if pushed by the pearl nuclei pushed out later. There is an advantage that it can be easily inserted in the vicinity region of.
