ok so shipping crabs such as fiddlers, red claws, etc. is a little harder then shipping fish or shrimp. first off you need a container. i use a small ziploc cointainer with a lid. second the water has to be brackish. i fix a bucket with a salinity of 1.010 and then just scoop however much water i need out of it into the container. it might not be ideal, but it'll work for 1-3 days. then you also have to have land. this can be as simple as a piece of styrafoam or a rock. furthermore the crabs need air. i just punch a few holes out of the top of the container. try to minimize the crabs to 1-2 crabs per container and only 1 if there's a male. finally the box needs to be packed full of newspapers so that the containers dont move around. (this is how i will be shipping my crabs. if you see any problems plz tell me. this is to help anyone else that needs to sell or export brackish/ land seeking crabs.)
