Súhrn: The contents of the constituents in cultured sea bass (Dicentrarchus labrax, Linnaeus 1758) were 69.3% moisture, 18.6% protein, 10.7% fat, 1.3% ash, 0.1% saccharides and 715 kJ•kg-1 energy. Main amino acids were aspartic acid and glutamic acid. High contents of essential amino acids, lysine and leucine, were detected. The fatty acid composition was 24.2% saturated (SFA), 41.0.% monounsaturated (MUFA) and 33.2% polyunsaturated fatty acids (PUFA). Palmitic acid was the primary saturated fatty acid, contributing approximately by 64% to the total SFA content. Major PUFA were linoleic acid (LA), docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). The cholesterol content of sea bass was 42 mg•kg-1. Ascorbic acid and niacin contents were higher than other water-soluble vitamins. The major macro- and microelements were K, P, Ca and Zn, Mn, respectively. As, Hg, Cd and Pb contents were far below the amount of the maximum allowable levels.
