The total content of fat soluble vitamins and their percentages in the recommended daily intake for humans per 100 g portion, fatty acids composition, the atherogenic (IA) and thrombogenicity (IT) indices in two freshwater fish species – Common carp (Cyprinus carpio) and European catfish (Sillurus glanis) were investigated. Retinol contents in fresh edible tissues of the Common carp and European catfish were found to be 30.8 ± 3.4 mg/100 g wet weight (ww) for the Common carp 30.8 ± 3.4 µg/100 g ww and 1.9 ± 0.1 µg/100 g ww for the European catfish, cholecalciferol contents 14.8 ± 1.0 and 3.1 ± 0.1 µg/100 g ww, and α-tocopherol contents 2764.5 ± 44.0 and 2182.5 ± 31.5 µg/100 g ww, respectively. The sum of monounsaturated FA accounted for 50.02% (catfish) and 23.15% (carp). Polyunsaturated FA (PUFA) showed a higher level in the carp (36.75%) and a lower one in the catfish (21.64%). Both fishes are good sources of cholecalciferol in terms of the recommended daily intake of vitamins established in Bulgaria. Three fat soluble vitamins, n-3 PUFAs content, and IA value were higher in carp. IT values were similar for both species.Keywords:
