Bundled, put into the refrigerator fresh room (not freezable) can keep more than 10 days, do not keep too long, consumption of nutrients. Dead seafood is best not to eat, bad stomach. If the crab has been dead for a long time, it doesn't smell fresh, and there is a fishy odor, then you can't eat it. You usually buy fresh crabs, first boil out, in the refrigerator can be saved, never put raw crabs in the refrigerator, because then the meat inside the crab is gone.
