Abstract	Processing raw foods into food products generates by-products and processing aquatic foods is not an exception since it requires removal of bones, skin, head and viscera, which accounts for approximately 60–70 g/100 g of the fish weight. According to EC regulation No. 1774/2002 fish by-products are classified as hazardous material. This means that their disposal is strictly regulated. In this paper we exploited the possibility of processing trout by-products in an experimental anaerobic digestion system to generate biogas. Substrates with different concentrations of organic matter were loaded into the system obtaining an increase in biogas production by increasing the concentration of organic matter. However, loading excessive quantities of substrate resulted in a temporary stop of the process due to the high acidification, associated with the fast degradation of organic matter and/or lipids inhibition of the methanogenesis step. The biogas production was about 730 m$^{3}$ biogas/ton of VS which places trout by-products among the most suitable substrate for anaerobic digestion.
