In order to maintain the considerable export of whitefish to the United States, detection and removal of the parasitic cysts is required. At present, this is done by candling, that is the transillumination of the skinless fillets, and by manually cutting out any cysts that are detected. This process, however, is not fully effective and closer inspection sometimes reveals cysts after the fillets have passed through an industrial candling process. In an endeavour to improve existing candling methods the optical problems in industrial candling were investigated.
