Growth, feed utilization and flesh quality of European sea bass (Dicentrarchus labrax) fed diets containing vegetable oils: A time-course study on the effect of a re-feeding period with a 100% fish oil diet

After 150 days of re-feeding period with a 100% fish oil diet, DHA levels were restored in those fish previously fed diets containing vegetable oils, but EPA levels remained lower when compared with fish fed 100% FO diet. Flesh content of linoleic and linolenic acids remained higher in those fish previously fed soybean and linseed oil containing diets, respectively.
