DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for vibrating live fish and a live fish vibrating machine.

[0002]

2. Description of the Related Art Various methods have been devised to maintain the freshness of fish that puts freshness first. In particular, for high-grade fish such as sea bream, a method of vigorously processing live fish when shipping is adopted. . Conventionally, when utilizing this live fish, an experienced worker hits the hook with a hand hook into the head of the live fish, or a live fish is inserted between endless belts to mechanize the work. There is a device in which a live fish is squeezed by moving a needle into the head of the live fish at a position where it is temporarily stopped.

[0003]

Live fish are quickly used after landing, and breams and the like are also used for knotting and the like. Therefore, care must be taken so that the wound is not noticeable on the determined body side. However, in the manual method described above, a violent fish must be grasped and turned quickly in the case of a fish whose squeezing side is determined, and in particular, a fin of a sea bream or the like has a sharp thorn, which is very dangerous. However, there is a problem that the work of mass-processing while paying attention to them requires sufficient skill, and the work condition is not good because the work is often performed in the middle of the night. There was a problem that the successor was difficult to grow due to the shortage. Further, in the method in which the squeezing step is performed during the conveyance while being sandwiched between the belts, even if a live fish having a similar size in a cultured fish with respect to the needle at a fixed position, the tip of the needle is the head. There is a problem that it is difficult to always accurately stop the live fish in a fixed position so as to pierce the predetermined position of the live fish, and it may not be possible to obtain a sufficiently finished state. As for staking work, manual work is still mainstream.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to always stop live fish accurately at a fixed position so that all live fish can be fully utilized. It is an object of the present invention to provide a live fish revitalizing method and a live fish revitalizing machine which can be operated safely without requiring skilled skills.

[0005] It is another object of the present invention to provide a live-fish squeezing machine for bleeding simultaneously with squeezing.

[0006]

According to a first aspect of the present invention, there is provided a live fish revitalizing method according to the first aspect of the present invention, wherein the live fish is inverted by a transport path such that a head thereof is located below a tail fin. The head of the live fish is positioned and held by fitting the head of the live fish into the recess for receiving the head that is opened upward, and then the vital point of the live fish is advanced by moving the needle point to a predetermined position above the recess. In the method of reviving live fish, which has been destroyed ,
