Abstract

In this study growth and lipid composition of gilthead sea bream (Sparus aurata) will be compared after feeding a diet containing Camelina sativa oil (CO) as a 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 n-3 precursor, 18:3n-3; high levels of mono- and polyunsaturated fatty acids, as well as significant amounts of alpha-tocopherol, a potent antioxidant. Diets will be formulated to meet the nutritional requirements for sea bream, and will contain either FO or CO as the main lipid source. An experiment will be conducted (triplicate tanks for FO and CO) with gilthead sea bream of mean initial weight of about 100-150 g fed experimental diets for 16 weeks in seawater. (AU)
