Method and equipment for the manufacture of fish silage pellets. In order that the manufacture of fish silage pellets would be a pro-environmental process so that the phosphorus effluents into natural waters from cultured fish eating the pellets would be remarkably low, the pellets are manufactured according to the invention by a method, which is essentially characterized by the following steps: waste fish and guts are ground into a mass and/or other animal tissues are ground to a mass and/or a mass is made of fish meal by adding water thereto; the mass obtained is mixed with a diluted acid by means of which acid the pH of the mass is adjusted so that the upper limit is a pH still preventing bacterial activity and the lower limit a pH still permitting the activity of the digestive enzymes of the waste fish; to the mass is added fodder meal, necessary vitamins and a binder and it is pressed into pellets. |
