Abstract:

The nutritional quality of commercially important farmed fish species, i.e. sea bream (Sparus aurata), sea bass (Dicentrarchus labrax), dentex (Dentex dentex) and turbot (Scophthalmus maximus) was investigated. Dentex was shown to have twice as high omega-3 fatty acid content and two to four times higher eicosapentaenoic (EPA) and docosahexaenoic (DHA) acid content as compared to other fish species. The recommended n-6/n-3 ratio was determined in all fish species, whereas the recommended PUFA/SFA ratio was not seen in turbot. Except of turbot, all other fish species matched the recommended atherogenic index (AI), the thrombogenic index (TI) and the ratio of hypocholesterolemic over hypercholesterolemic fatty acids (HH), while the highest the flesh lipid quality (FLQ) value was determined in dentex.
