Mud crabs, also called mangrove crabs, are the large edible crabs of the genus Scylla, above all Scylla serrata, that inhabit estuaries and coastal waters of the Pacific and Indian Oceans. Wild fisheries and a growing aquaculture sector in Asia and Australia supply markets that prize their moist, delicately sweet claw and body meat. Cooks steam, poach, pan-fry, or barbecue them, serving the meat plain or working it into soups, curries, and pasta fillings. Quality rests on live handling, rapid humane killing, and immediate cooking or chilling, while farmed production now steadies a supply once dependent on seasonal wild catch.
