窒息死し、また周囲の他のイカも窒息死する。さらに、
状況によって共食いをする。However, in both cases, the targets of transportation are fish other than squid. On the other hand, squid has different properties from ordinary fish, and conventional methods of transporting live fish cannot be applied as is. In other words, squid are more sensitive to the environment than normal fish, and when they vomit scum, the scum they vomit gets stuck in the cod, causing them to suffocate, and other squids in the vicinity to suffocate as well. moreover,
Cannibalism depending on the situation.
一方、そのようなイカの特異性を考慮したイカの飼育装

いをする。The device disclosed here is certainly suitable for squid breeding. However, although this device is suitable for breeding, it is not practical to use it as is for transportation. That is, if the method is used as it is, the amount of squid transported per unit volume of the aquarium will be small, and the transportation cost will increase. However, if the amount of squid transported per unit volume of the aquarium is increased, even if the amount of oxygen supplied is increased, the squid will easily become oxygen-deficient, weakening the squid, and in some cases cannibalism.
そこで本発明の目的は、小さい水槽容積で多量のイカを
輸送することができ、かつイカが弱ったり、共食いをし
たりすることなく、生きたままイカを輸送することがで
