Hairy crabs sent by courier can survive for 3-5 days, and the courier company will adopt cold chain distribution during transportation to maintain the freshness and survival rate of crabs. Put the hairy crabs in a container with good air permeability. You can choose a special crab box or foam box, and make sure there is enough space inside the box for crabs to move. Wet sponge or wet paper towel can be placed in the box to maintain proper humidity. Try to choose a shorter transportation time to reduce the hunger and pressure of hairy crabs during transportation.
