The development of Mediterranean aquaculture from the early eighties has set up a new industry which is planned to produce around 50,000 tons of fish in 1996. According to present technical ratios, this represents roughly 100,000 tons/year of aquafeed shared among over 20 fish feed manufacturers. Pressed or extruded pellets, lipid/protein content, vitamin levels, essential amino and fatty acids, floating or sinking pellets... are still questions frequently asked to fish feed manufacturers who use a wide range of raw materials and techniques to adapt their products to the fish needs in a highly competitive environment. Traditionally situated in northern countries for historical reasons, all large fishfeed manufacturers usually include a southern development in their strategy. Other more recent manufacturers have directly started their activity in Mediterranean countries. Although many feeds on the seabass and seabream market come directly from the salmon and trout industry, some noticeable R & D have been made to produce specific feeds for these species, formulated to better cover the needs of these fish and so help the fish farming industry to achieve better performance and minimize pollution discharge to the environment.
