Abstract

Introduction: Caspian kutum (Rutilus frisii) is of great importance among consumers. The aim of this study is to investigate the changes in the Fatty Acid profiles of fish caught in east of Sari and west of Noshahr. Materials and Methods: The studied fish (three fish from each gender) were purchased in winter and spring from Sari Shahid Beheshti Cooperative and the Veterans Cooperative of Noshahr (east and west of Mazandaran province, respectively). Biochemical analysis and Fatty Acid profile were determined by the application of gas chromatography using standard methods. Results: Stearic acid, oleic acid, and DHA were the highest in Sari in winter being the significantly different from other Fatty Acids (p < 0. 05). Total Fatty Acids in male and female fish from Noshahr and male fish from Sari were significantly lower in spring than in the others, and male and female fish from Nowshahr contained relatively higher total Fatty Acids in winter. Maximum DHA values were higher than EPA in both sexes, seasons, and regions. The chemical composition of male and female fish did not differ significantly in both seasons and regions (p > 0. 05). SFA percentages in both sexes and regions were generally higher in winter than in spring, while PUFA percentages in both sexes and regions were higher in spring than in winter. The percentage of ω-3 Fatty Acids (41. 12%) in winter samples of Noshahr was higher than that (30. 91%) in Sari, and it was higher in spring samples of Sari (55. 27%) than that of Noshahr (17. 29%). The lowest total ratios of ω-3/ω-6 were obtained in Sari (3. 12) in male fish in winter and in Noshahr (3. 23) in spring. The highest PUFA/SFA ratios were observed in Sari (1. 9) and Noshahr (0. 74) kutum in spring and winter, respectively. Conclusion: Fish examined in winter contained more Fatty Acids (especially DHA and EPA) in the muscle and are therefore more important for human consumption. The two regions, two seasons, and two sexes had significant effects on body Biochemical Composition and Fatty Acid profile of Caspian Sea kutum.
