BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a method for transporting live fish. More particularly, the present invention relates to a method for transporting live fish, in which live fish are brought into a dormant state in order that they can be successfully transported even when the transportation takes many hours and that the transportation can be made at low cost, and a container for use in the method.
BACKGROUND OF THE INVENTION
Storage or transportation of fresh fish and shellfish has been made by packing them in a container with crushed ice or salt ice without freezing them. It is however impossible to resuscitate the fish and shellfish thus stored or transported. For this reason, transportation of fish and shellfish, and in particular, that of fish is recently made by placing them in water to keep them alive.
However, in the above method, live fish swim about in a small container or are shaken during the transportation, and so tend to be damaged. In addition, it is necessary to transport a large quantity of water together with fish. This method is therefore also disadvantageous in the transportation cost. To reduce the transportation cost, an increased number of live fish were placed in one container. However, after the fish were transported in this manner, they were found to be more considerably damaged.
SUMMARY OF THE INVENTION
The inventor of the present invention made studies in order to obtain a method for transporting live fish, capable of keeping fish alive for a long transportation time. As a result, it was found that live fish which have been transported in a dormant state can be resuscitated after the transportation. The present invention has been accomplished on the basis of the above finding.
Accordingly, an object of the present invention is to provide a method for transporting live fish, capable of transporting live fish even when the transportation takes many hours.
A further object of the present invention is to provide a method for transporting live fish, capable of transporting live fish without using water even when the transportation takes many hours.
A still further object of the present invention is to provide a container for use in the above methods for transporting live fish.
The method for transporting live fish according to the present invention comprises the steps of cooling the live fish placed in water to bring the fish into a dormant state, and transporting the live fish in the dormant state placed under the ambient temperature thereof maintained at -1.degree. to 10.degree. C.
The container apparatus for transporting live fish comprises a vessel made of heat insulating material, a panel mounted on an inner surface of the vessel for heating a content in the vessel, a lid made of heat insulating material and used to close the vessel, one or more wire cages capable of containing live fish, the cage or cages being placed or stacked in the vessel, and means for admitting or discharging a cooling medium into and out of the vessel.

DETAILED DESCRIPTION OF THE INVENTION
As used herein, the term "fish" is intended to refer not only to fish taxonomically classified but also to so-called "fishery products", and includes, for instance, saltwater fish, freshwater fish, Crustacea, shellfish and Reptilia.
In the method for transporting live fish according to the present invention, live fish are first placed in water and then cooled, whereby the fish are brought into a dormant state. In the present invention, live fish in a dormant state are directed to live fish in such a state that the fish are inactivated by a cooling treatment but can be resuscitated, that is, through anabiosis, when warmed even after the fish are preserved at a temperature of -1.degree. to 10.degree. C.
It is preferable to gradually cool the live fish placed in water so that the fish will no
