Florida's stone crab harvest season opens on 15 October and closes on 1 May, with the fishery shut for the five months in between. The dates are set by the Florida Fish and Wildlife Conservation Commission and they do not move for weather or demand.
What makes this fishery unusual
The crab is not killed. Harvesters take one or both claws and return the animal to the water, where it can regenerate what was taken. That is why the fishery has survived intensive commercial pressure around South Florida for a century when others have not.
It also explains the pricing. A claw is graded by size, from medium up through large, jumbo and colossal, and the jump between grades is steep. Regulators tightened the rules in 2020, shortening the season and raising the minimum legal claw size, both aimed at letting more crabs regenerate before they are harvested again.
When to actually eat them
Opening week is the worst value of the year. Demand spikes, supply is thin, and restaurants are pricing scarcity. Prices generally settle from late autumn, and the sweet spot for both price and size is usually January through March.
Claws are cooked immediately on the boat or at the dock, then chilled. They are never served hot, and a restaurant offering you warm stone crab is doing something unusual. The traditional accompaniment is a cold mustard sauce, and the shell is cracked for you.
Where it fits in a Miami trip
Stone crab is a Miami Beach institution and a Miami-wide seasonal marker. Most seafood restaurants across the county carry it in season, and fish markets sell claws by the pound, which is considerably cheaper than a dining room.
If your trip falls between May and mid-October and a menu is offering stone crab, it is frozen from the previous season. That is legal and often perfectly good. It is not the same thing.
