A nice sustainable fishery. Legal harvesting in the U.S. means that claws can only come from male crabs, and the smaller claw must be of a certain size (so the crab can feed/defend itself). The crabs grow back the claws and are said to be good for 3-5 cycles.
Last time I had stone crabs was buying it from a fisherman near Cape Coral in Fort Myers. Previously I used to go to Everglades City from Marco Island but that outlet decided to go wholesale only.
