The effect of using diferent commercial feeds in sea bream ( Sparus aurata L. 1758) and sea bass (Dicentrarchus labrax L. 1758) aquacultured in the Güllük Gulf (Muğla, Türkiye) on fatty acid profle

Abstract

The aim of this study was to investigate the efects of using diferent commercial feeds on growing performance and fatty acidprofle of sea bream and sea bass aquacultured in net cages. Four diferent fsh companies (i.e. 4 experimental groups) were given diferentcommercial feeds (extruded fsh feed) to be used regularly for 480 days. Omega-3 [eicosapentaenoic acid (EPA), docosahexaenoic acid(DHA)] values of feeds for groups 1, 2, 3, and 4 were 11.81%, 14.23%, 7.69%, and 12.01%, respectively. When compared, omega-3components in sea bass were higher than in sea bream. EPA and DHA fatty acids were 12.53% in sea bass and 11.06% in sea bream.When fatty acid contents of feeds were compared with fatty acid levels of sea bream and sea bass, it was determined that the totalmonounsaturated fatty acid (ΣMUFA) level was the highest in sea bass (38.13%) and sea bream fshes (39.12%) in group 3 given fshmeal that had the highest ΣMUFA content (38.05%). It was observed that the fatty acid profle of the sea bream and sea bass refectedthe fatty acid contents of the feeds used in their feeding.
