The processing of raw material for fishmeal and fish oil production essentially follows a cooking, pressing, extraction and drying cycle that separates out the fishmeal and fish oil, producing only steam as a byproduct.  In effect, a product that incorporates all of the raw material other than a major fraction of the water it contained is produced.  Processing follows strict quality management procedures to ensure that end product parameters are within recognised ranges for nutrients and contaminants.  The process is highly technical in order to retain the nutrient qualities that are found in the raw material as far as possible, and ensure that these are transferred to the end products of fishmeal and fish oil.
