The water temperature is detected by the water temperature meter,
When the water temperature display is 5-8 ° C, the entire amount of ice is discharged. If the temperature falls below this temperature, add seawater and adjust the temperature to 5-8 ° C. For red king crab, low-temperature seawater at 0 to 3 ° C is produced according to the above procedure. Crabs are placed in the low temperature seawater produced as described above at least one hour before shipping to allow them to fully acclimate to the low temperature. In addition, the water temperature of the cage normally is 5 to 10 ° C. for hair crab and 0 to 5 ° C. for king crab. In addition, the use of a circulation type fresh water producing apparatus in place of the above-mentioned cage provides the most preferable low temperature seawater making action.

(Packing processing) The crabs processed as described above are packed in a predetermined transport container for keeping cold by a predetermined means. 1 to 4 show a packing method in the transport box C. The transport box C is formed of a container body 1 and a lid portion 2 with a heat insulating material having a predetermined thickness, preferably Styrofoam.
The styrofoam product is inexpensive and lightweight, contributes to reduction of transportation cost, and is convenient for "courier service".
