Microalgae, being the primary producers of marine omega-3, are recognized as among the most prominent alternatives to fish oil in fish feed. Heterotrophic microalgae (HM) do not compete for light and can be produced on inexpensive low value raw materials in any part of the world, still the methods used for processing are too costly for bulk raw material production. Large scale production of HM (e.g. Schizochytrium sp.) with high lipid content (55-75% in dry matter) and as much as 30% DHA of total lipids is a reality today using well established fermentation technologies. It is thus possible to supplement salmon diets with marine omega-3 fatty acids from these algae and support further salmon production growth. To reach this goal, further improvements in cost efficiency and end product quality in the downstream processing of HM are needed as well as convincing studies on the lifelong metabolic effects in fish fed HM rich diets. Provision of adequate quantities of wet and dry raw material for pilot scale processing, feed technology and fish feeding trials are thus necessary. In this project Alltech Inc holds this role, rendering the risks of not achieving the set goals very low. The project works include i) development of downstream processing technologies to improve HM dewatering cost and saturated lipid digestibility, ii) development of ingredient specific extrusion protocols, iii) screening of main metabolic effects of HM oils in salmon cell cultures, iv) studies on the biological effects of dietary HM on farmed salmon focusing on fish welfare and health, growth performance, product qualit y and metabolic effects, and v) establishment of the economic feasibility of using HM as sources of omega-3 fatty acids in salmon feeds.
