Description of the Related Art ATP, adenosine triphosphate, in the muscles of live fish is not regenerated after death and is continuously consumed to accelerate postmortem rigidity of live fish. Therefore, in order to maintain ATP at a high level immediately before death, reduce post-mortem ATP consumption, delay post-mortem rigidity of live fish, and maintain freshness for a long period of time, the head of live fish has been immediately fixed with a hand key. Kill, then put a knife inside the gills to completely cut the spinal cord and perform an error, insert a knife from the side of the caudal vertebral body and cut only the caudal vertebral body. The vertebral body of the caudal vertebral body was cut, and pressurized oxygen was blown from the nerve arch above the vertebral body of the caudal vertebral body to destroy and remove the nerves of live fish. In this method, the pretreatment was troublesome and the blown spinal cord was scattered, which was unsanitary.
