Abstract

The composition of tail muscle fatty acids from wild and cultured bluefin tuna reared on a diet based on herring and sardine, along with the plasma lipid profile of the farmed individuals, was determined. The total lipid content of farmed bluefin in this study was 0.922 g/100 g, or 3.49 g of SAFA, 4.48 g of MUFA, 2.58 g PUFA n-3, and 0.37 g of PUFA n-6 fatty acids ; for wild specimens it was 0.920 g/100 g, or 2.85 g of SAFA, 4.82 g of MUFA, 2.78 g PUFA n-3, and 0.27 g of PUFA n-6 fatty acids. Major fatty acids in this study were 16:0 ; 16:1, n-7 ; 18:1, n-9 and DHA 22:6, n-3 acids. The sum of these major components accounted for more than 57 % and 80 % of the total fatty acids in all samples of farmed and wild tuna, respectively. No significant differences in proximate composition were demonstrated between farmed and wild samples, except for energy value, in favor of the farmed tuna. Statistically, GLU tends to increase together with CHOL and TRIG, since for these pairs it showed positive correlation coefficients and P > 0.05. Some measured tuna metabolites demonstrated strong mutual correlations, especially GLU, CHOL and TRIG, which are crucial factors in lipid profile of animals.
