DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for keeping fish alive.

[0002]

2. Description of the Related Art Conventionally, when a fisherman catches a sea bream, he performs a so-called live squeezing, such as hitting the medulla with the back of the blade or hammering a hand hook into the medulla and then cutting the artery to remove blood. ing. This is done in order to maintain the freshness of the fish, but the word freshness has two meanings, for example, when freshness is poor when looking at sashimi and when freshness of dried fish is poor. The meaning is different. Freshness in the case of sashimi is the so-called freshness, which means freshness that is particularly problematic when eating raw fish, and in the case of dried fish mackerel, it is not so lively but whether it can be eaten, so-called rot level Freshness in the sense. Postmortem changes in fish generally proceed in the order of stiffness, softening, and decay. That is, in a living state, the state is an aerobic state in which oxygen is sufficiently supplied, and after death, oxygen is not supplied and the state becomes anaerobic. Rigidity begins gradually after death, and finally reaches a state of complete rigidity.
It has almost the same value as live fish in the consumer market. ATP (adenosine triphosphate) in the muscle of the fish
Is present in a considerable amount, but ATP almost disappears in a completely rigid state. When complete stiffness continues for a certain period of time, hardening begins and the stiffness begins to melt. This state is usually called fresh seafood. After that, softening occurs, and it goes into a putrefaction state after an initial putrefaction with a slight off-flavor. It is generally said that life is good from the time immediately after death to hardening, and since then it is said that freshness deteriorates and life is poor. To keep the state of "live" as long as possible, "live" so-called immediate killing, fish killed in agony have an extremely low ATP content, while fish killed immediately have low energy consumption. High ATP content delays onset of stiffness.
It is said that the processing of "Alive" is also based on this finding, but it is said that the effect of "Alive" is greater if not only blood is drawn immediately after killing but also the nerves are removed. . However, the conventional work of hammering a hand hook into the medulla oblongata and cutting the artery to remove blood is difficult when working with a large amount of fish, and it is difficult to extract nerves. Was.
