Sažetak
Diplodus sargus, L. (the white sea bream) is a commercially important fish species in the Mediterranean Sea. It is known that the lipid content and fatty acid composition of fish tissues could be influenced by different eco-physical parameters and environmental conditions. However, published fatty acid compositional data of fish from the Adriatic Sea is still meager. Therefore, the aim of this study was to determine the hepatic fatty acid composition of the white sea bream, Diplodus sargus, captured in the North Adriatic Sea, Croatia in different seasons of the year. Fatty acid compositions of the liver neutral and polar lipid fractions in four different seasons were determined. The major constituents of total fatty acids were saturates: palmitic (16:0) and stearic acid (18:0) ; monounsaturated fatty acids: oleic (18:1n-9), and palmitoleic acid, (16:1n-7), while arachidonic acid (20:4n-6), eicosapentaenoic (20:5n-3) and docosahexaenoic acid (22:6n-3), were the major polyunsaturated fatty acids. Their amounts and ratios differed significantly between seasons in different lipid fractions. Total unsaturated fatty acids in all analyzed lipid fractions were the highest in the winter period. Saturated fatty acids were the highest in the spring period in all lipid fractions. Eicosapentaenoic and docosahexaenoic acid achieved the highest values in triacylglycerols in the winter period. Unsaturation indexes and n-3/n-6 values were also influenced by season. This study revealed a seasonality pattern of Diplodus sargus hepatic fatty acid composition.
