Abstract :The biochemical composition of fish differs according to seasons and habitat. This study aims to compare seasonal  variations in the fatty acid composition of garfish insert ignore into journalissuearticles values(Belone euxini);, Mediterranean horse mackerel insert ignore into journalissuearticles values(Trachurus mediterraneus);  and red mullet insert ignore into journalissuearticles values(Mullus barbatus);, commercially caught from different zones of Eastern Black Sea of Turkey. The  results demonstrated significant seasonal variations in the levels of total saturated fatty acids insert ignore into journalissuearticles values(ΣSFA);, monounsaturated  fatty acids insert ignore into journalissuearticles values(ΣMUFA); and polyunsaturated fatty acids insert ignore into journalissuearticles values(ΣPUFA); in the fish insert ignore into journalissuearticles values(p<0.05);. The highest percentage of omega-3  and ΣPUFA fatty acids were observed in autumn for red mullet and Mediterranean horse mackerel, while the highest  values of these fatty acids were found in spring for garfish. The highest eicosapentaenoic acid + docosahexaenoic  acid insert ignore into journalissuearticles values(EPA+DHA); levels were obtained for garfish and the lowest for red mullet. Significant seasonal variations were also  observed among the three-fish species in values of fatty acids expressed as mg/100g in the edible portion insert ignore into journalissuearticles values(p<0.05);.  Considering, the highest levels of EPA+DHA, only 145 g of garfish is found enough to meet the weekly requirement of  EPA+DHA for winter; although, consumption of approximately 431 g of edible muscle is required for red mullet to meet  the same requirement. About 295 g edible muscle of Mediterranean horse mackerel was needed to meet the requisite  amount of nutrients in summer. Therefore, this study implies that garfish has a better nutritional value for human consumption  due to higher contents of EPA+DHA compared to other two species.
