Can both stone crab claws be harvested?

Both claws of a stone crab may be harvested if they are of legal size. Although it is currently lawful to harvest both of a stone crab's claws, this practice leaves the stone crab with few alternatives to defend itself from predators. Although the crab can still obtain minimal amounts of food with no claws, having one claw (if the other one is harvested) will help the crab obtain greater amounts of food in a shorter amount of time. Stone crabs (like other crustaceans) have the ability to grow back their claws, but this process requires a large amount of energy in the form of food. The quicker the crab can obtain the energy required to molt and grow its lost claw, the sooner this renewable delicacy will have another claw to replace the missing one.
