Investigation of Quality Index Parameters and comparison of fatty acids of some Sparidae fish species in Çanakkale city (northern Aegean Sea, Türkiye)

This study examined the fatty acid contents of Blotched picarel (Spicara maena Linnaeus, 1758), Blackspot seabream (Pagellus bogaraveo Brünnich, 1768), Saddled seabream (Oblada melanura Linnaeus, 1758), Bogue (Boops boops Linnaeus, 1758) and Sand steenbras (Lithognathus mormyrus Linnaeus, 1758) fish species in Çanakkale province and compared them with each other. In this study, fatty acids and quality parameters (LQI) in the meat of some sparid fish species which are important in human consumption were examined. There are three main differences that set this study apart from others. Firstly, the study area is located in the Çanakkale region. Secondly, the meats of sparid fish species are examined. Finally, the third difference is the investigation of the quality index of the fat in addition to the fatty acids in the region and the fish meats. The quality index parameters of these fish oils were calculated and compared with each other. Unsaturated fatty acid ratios were found to be over 60% in all fish studied. The highest unsaturated fatty acid content was observed in Boops boops with 67.34%. ω-3 fatty acids were highest in Oblada melanura with 43.33% and lowest in Lithognathus mormyrus with 34.77%. Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) were found to be between 6-9% and 22-30%, respectively, in the fish. The AI, h/H, and TI quality index parameters were calculated between 0.42-50, 2.28-2.75, and 0.22-0.26, respectively. In addition, within the scope of the study, the amount of fatty acids was calculated on edible 100 g portion (EP: Edible portion, mg FA/ 100 g fresh portion) of each fish. The highest EP value for ω-3 fatty acids was calculated as 1367 mg/100 g in Pagellus bogaraveo.
