A new system for automatic detection of nematodes in cod has been evaluated under industrial conditions. The results for detection of pale nematodes corresponds to earlier findings showing that automatic detection of nematodes can achieve similar or better results than manual inspection of cod fillets on candling tables under industrial conditions. The number of false positives is reduced when inspecting fillets after trimming, suggesting that the false positives are elements being removed from the fillets during trimming. The system seems promising for being incorporated into new filleting lines for white fish in the near future. It should be placed after a pre-trimming, and can be used to divide the production flow in two; one clean stream going directly to portioning and packing and the other to manual trimming.
