Automation of the trimming operation is a problem with high priority in the fish processing industry. This is a natural follow up of the automatic pin bone removal project. This work has focused on developing Imaging Spectroscopy for detection of nematodes, blood spots, black lining and skin remnants. Development of technology for removal of those items is not a part of this project. Results so far shows that Imaging Spectroscopy in combination with multivariate analysis can discriminate nematodes, blood spots, black lining and skin remnants even when the number of wavelengths applied is as low as 10. This is promising in view of the possibility for developing a detection prototype for the fish processing industry.
