Krajnovic-Ozretic, M. | Najdek, M. | Ozretic, B.
Growth rate and assimilation of essential fatty acids were analysed in sea bass (Dicentrachus labrax L.) fed different diets. Gas chromatographic analyses of total lipids in commercial diets indicated excessive presence of saturated, mono and dienoic fatty acids, while the content of omega3 HUFA was very low. Fatty acid patterns of liver and white muscle farmed sea bass reflected the contents of the dietary lipids. The conceotration of polyunsaturated fatty acids, particularly omega3 HUFA was significantly lower when compared with samples from the wild population. The atherogenic and fish lipid quality indices confirmed the higher nutritional quality of wild sea bass when compared with farmed fishes.
