Özet
Platichthys flesus is an important fisheries resource in the all Black Sea used for human consumption. It is an economic species, being caught for commercial pur- poses both in Europe and Türkiye. Therefore, the present study aimed to determine the nutritional quality indices and changes in biochemical and fatty acid compositions in flounder (Platichthys flesus) fillets and gonads caught from the Southern Black Sea in the reproduction period. While the moisture and lipid contents of flounder fillets were higher than the gonads, the protein and ash contents were determined to be higher in the gonads than in the fillets. The differences among them were found to be statistically significant (P<0.05). C14:0, C18:0, C16:1, C18:1n-9c, C20:1, C18:2n-6c and C18:3n-3 fatty acids in fillets, C16:0, C20:4n-6, C20:5n-3 and C22:6n-3 fatty acids in gonads were dominant. There were statistical differences between them (P<0.05). Among total fatty acids, SFA and PUFA were detected at higher rates in gonads and MUFA in fillets (P<0.05). The index of thrombogenicity (IT), hypocholesterolemic/ Hypercholest- er-olemic (h/H) and flesh lipid quality (FLQ) values were determined higher in gonads, and the index of atherogenicity (IA) value was determined higher in fillets. While there was no statistical difference between IT and h/H values (P>0.05), the differences be- tween IA and FLQ values were found to be significant (P<0.05). As a result, it is recommended to consume flounder, having commercial importance in Black Sea and important nutritional value in terms of protein and fatty acids compositions.
