Sažetak
The fat content and fatty acid composition of sea bass (Dicentrarchus labrax) cultivated on different fish farms in the Adriatic sea and
sampled during the autumn-winter period, on the Croatian market since November 2013 until March 2014, were evaluated. A total
of 64 samples of sea bass of commercial size were analyzed. The results showed that there were statistically significant differences
(p<0.05) among sampled groups in the proportion of total fat content and composition of fatty acid groups. These differences can be
attributed to the different farming systems and diets the fish were fed on, but also the sampling period. Among the polyunsaturated
fatty acids omega-6 fatty acids were dominant, and the value of omega-3 fatty acids has proven to be lower than those reported in
other studies, possibly because of diet. The resulting omega-6/omega-3 ratio was 3.04±0.61, according to the health recommendations
(3-5:1).
