If it is consumed within 1-2 days, it can be fed with sea water or pure water plus sea salt. If it is eaten after a long time, it can be packed in foam box and put into the fridge freezer, but it is necessary to add water without crab in the foam box. How can live sea crabs be kept fresh? If sea water or light salt water is used to feed sea crabs, be careful not to put too much water. Generally, they just don't have crabs, and they should be placed in a cool and humid place.
If you need to send gifts, put the crab into the foam box and put enough ice.
