Title: Alternative lipid sources for fish feed and farmed fish quality
Abstract: Aquaculture production globally is estimated to be increasing. This has meant that demand for extruded feeds has increased in line with production. Culture of fish has traditionally used diet formulations based on Fish Meal ["FM"] and Fish Oil ["FO"]. However, while this has been successful, and is scientifically and nutritionally sound, fish oil production worldwide is static or in decline and there is no likelihood that production can be increased if fisheries are to be managed in a sustainable fashion. The lipid component in aquafeeds must meet both energy and Essential Fatty Acid ["EFA"] requirements to allow the rapid growth and development required in modern aquaculture production. Continued expansion of aquaculture production would require the use of alternative oil sources, with terrestrial plant oils the most likely candidates, to provide the large quantities of oil required, using sustainable methods of crop production. The rapid rise in prices of marine-derived raw materials has meant that FO is more expensive than a number of the major oilseed crops. This chapter discusses the effects of aquafeeds containing reduced levels of marine raw materials on fish growth and health. It further discusses the effects of including plant oils on the nutritional quality of farmed fish, in terms of n-3 HUFA content, and their nutritional benefits for human nutrition.
