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.

Extraction of berry oil can be carried out by different methods. Berry oil is generally obtained by hydrodistillation or steam distillation of dried immature berries. When supercritical CO2 extraction techniques are employed for extraction of berry oil, the oil obtained is of superior quality and flavour, compared with steam distilled or hydrodistilled oil.

There are several ,techniques, that allow to improve oil recovery and can be classified into primary, secondary and tertiary recovery,. The former consists of the ,extraction, of oil via natural rise or pumps. It let to recover only 5-15% of hydrocarbons. Secondary recovery, instead, consists of the injection of water/gas in the reservoirs.
