Abstract
Abstract In this study growth and lipid composition of Atlantic salmon, rainbow trout and Atlantic cod were compared after feeding a diet containing camelina oil (CO) as a full replacement of fish oil (FO). CO is an interesting candidate for replacement due to its high total lipid content (40%) and a high amount of the ω3 precursor, 18:3ω3; high levels of mono- and polyunsaturated fatty acids, as well as significant amounts of γ-tocopherol, a potent antioxidant. Diets were formulated to meet the nutritional requirements for each species, and either contained FO or CO as the main lipid source. Three separate experiments were conducted (triplicate tanks for FO and CO): Atlantic salmon (mean initial weight 242 ± 46 g) were fed experimental diets for 16 weeks in seawater at 14 °C, rainbow trout (44.9 ± 10 g) were fed for 12 weeks in freshwater at 14 °C, and Atlantic cod (14.4 ± 1.6 g) were fed for 13 weeks at 10 °C. Growth performance of Atlantic cod was significantly affected by dietary CO in comparison to cod fed the FO diet (p
