A method for shucking bi-valve shellfish, especially clams, includes imparting a wide array of infrared energy from at least one infrared heater from above to a first shell of the bi-valve shellfish sufficient to detach an adductor muscle from the first shell. The bi-valve shellfish are inverted to expose a second shell. Infrared energy is imparted again from above to a second shell of the bi-valve shellfish sufficient to release a shellfish meat from between the first and shell and the second shell. A system for carrying out this method includes a tank for washing the shellfish, a dryer, the infrared heaters, a device for inverting the shellfish, a tank for quenching the shellfish, and a conveyor for transporting the shellfish under the infrared heaters.
