In this study, the suitability and usability of fish skin and bones generated as waste in terms of lipids and fatty acids were investigated. In this paper, the cultured Sparus aurata (Sea bream), Dicentrarchus labrax (Sea Bass) and Oncorhynchus mykiss (Rainbow trout) fish were examined. Within the scope of the study, the fatty acids and lipid quality index parameters in the skin and bones of the cultured fish were calculated. The lipid quality index was examined for skin and bone of cultured fish using the Atherogenicity Index (AI), Thrombogenicity Index (TI), Flesh-lipid quality (FLQ), Hypocholesterolemic/hypercholesterolemic ratio (h/H), Health-promoting index (HPI), Unsaturation Index (UI), The polyene index (PI), Hypercholesterolaemic fatty acids (OFA), and Desirable fatty acids (DFA). Among these indices, the AI values were obtained between 0.18 and 0.24 in all fish bone and skins The TI values also obtained between 0.71 and 0.98 for all bone and skins. Among the important fatty acids, EPA was calculated between 0,34 and 2.22g/100g in skins and 0.29 and 0.87g/100g in bones. According to our results, it has been determined that the fatty acids levels of ?-3, ?-6, and Linoleic acid (LA) in fish skin and bones based on 100g of dry weight composition (DWC) are higher than the daily consumption levels recommended by The Australian National Health and Medical Research Council (NHMRC). In conclusion, it can be said that the skin and bones of cultured fish can be used for dietary consumption purposes.
