Sažetak
The nutritional importance of fish consumption is associated with the content of n-3 polyunsaturated fatty acids (n-3 PUFA)  1 . The two-banded seabream, Diplodus vulgaris, L. occupies an important place in the fishing activity of Croatia because it is appreciated in the mediterranean type of diet  2 . The fish muscle tissue was analyzed for the lipid and moisture contents. The fatty acid composition of neutral (triglycerides-TG) and polar (phosphatidylethanolamine-PE, phosphatidylcholine-PC, phosphatidylinositol/ phosphatidylserine-PIPS) lipid classes was determined. Fish specimens were obtained from the Kvarner Bay, north of the Adriatic Sea. The total lipid content amounted to 1, 0  0, 4 %. The moisture content was 77, 8  2, 7 %. There have been identified 16 different fatty acids in the analyzed fish muscle tissue samples. The major constituents of the total fatty acids were saturates: palmitic (C16:0) and stearic acid (C18:0) ; monoenes: oleic (C18:1 n-9) and palmitoleic acid (C16:1) ; polyunsaturated: arachidonic (C20:4 n-6), eicosapentaenoic (C20:5 n-3, EPA) and docosahexaenoic acid (C22:6 n-3, DHA). The fatty acid composition showed a more favorable profile in neutral lipid fractions, containing more mono-, di- and poly- unsaturates. The degree of unsaturation, expressed as unsaturation index, amounted from 0, 93 to 1, 18. The n-3/n-6 ratio, as a marker of biomedical importance for fish lipids was also calculated and amounted from 0, 95 to 1, 85. It can be concluded that D. Vulgaris, L. is a good source of natural n-3 PUFA, which are known for their many benefits in human health and diseases. Therefore, it would be suitable for inclusion in highly unsaturated low-fat diets.
