There are a number of processes that can be used to convert raw fish and cuttings into fishmeal and oil. These fall into several categories defined as wet rendering, hydrolysis, silage production (autolysis), dry rendering and solvent extraction. The wet rendering process is used in the majority of the factories that produce fish oil worldwide.

Gases suitable for supercritical extraction include carbon dioxide, nitrogen, methane, ethane, ethylene, nitrous oxide, sulfur dioxide, propane, propylene, ammonia, and sulfur hexafluoride. An advantage of supercritical extraction is that it can take place at low temperature, thus preserving the quality of temperature-sensitive components (List and Schmidt, 1989).
