A detecting/removing method and a device therefor, used to examine whether o r not shells still remain on crustaceans such as lobsters and crabs from which shells are supposed to have been torn off. The device comprises an irradiati on means (1) for applying a ray of light in a specific wavelength area onto a crustacean (20) having its shell torn off, a CCD camera (40) disposed opposi te to the crustacean, and a means (41) for determining whether or not an untorn shell still remains on the crustacean based on the intensity information of fluorescence obtained from an image captured by the CCD camera, a crustacean having its untorn shell kept on it according to information from the means (41) being removed by removing means (5, 6, 7). |
