Sažetak
The aim of the study was to investigate quality parameters of European sea-bass (Dicentrarchus labrax) and sea-bream (Sparus aurata) as some of the most important finfish species cultivated in the Mediterranean region, widely consumed in this part of Europe. Fish sampling was carried out throughout a two-year period, varying thereby the sampling season and farming location (within the Croatian state territory of the Adriatic Sea region). In total, 90 fish per species were analysed for their basic chemical parameters, mineral content and fatty acid composition using standard analytical methods and statistical analysis was performed with a statistical significance set at 95%. The results of the study pointed towards seasonal variations in total fat content found in edible parts of both fish species, with its minimum values observed in late spring and its maximum values observed in early autumn. The inter- species comparison of fish fat content determined in the same sampling period revealed the total fat content of sea-bream to be significantly (p < 0.05) higher than that of sea-bass. The sampling season was observed to significantly impact sea-bass’s moisture, fat and crude protein content, as well as sea- bream’s moisture and fat content. The farming site failed to exhibit any significant impact on quality parameters and mineral composition of either species under study (p > 0.05). Fatty acid composition was shown to be influenced both by the sampling season and the farming location and to be dependent on the feeding strategy. Since fish is promoted as a valuable source of n-3 fatty acids, efforts should be made to properly tailor its lipid quality, basically relying on dietary adjustments so as to optimise fat deposition and fatty acid profile.
