Four isonitrogenous and isolipidic diets were formulated with either fish oil (FO), soybean oil (SO), linseed oil (LO) or a mixture of SO and LO (SO+LO). The results showed that survival, weight gain, feed efficiency and protein efficiency ratios of black sea bream were not affected by dietary lipid sources (p>0.05). Liver and muscle of fish fed the SO diet had high concentration of linoleic acid, while those of fish fed the LO diet were high in linolenic acid. Liver and muscle of fish fed the FO diet had significantly (p M3 ER -
