Abstract
In this research the fatty acid composition of different tissues of mature trout caught from Yeşildere creek in the Fırat region were investigated. In the adipose, gonad, liver and muscle tissues, the differences among the percentages of monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (n-3, n-6 PUFA) and the eicosapentaenoic acid (EPA)/decosahexaenoic acid (DHA) ratio were statistically significant (P < 0.01). However, the differences in the saturated fatty acids (SFA) of tissues were not distinctive. The most important fatty acids were palmitic (16:0), stearic (18:0) and miristic (14:0) in SFA and 18:1 n-9 and 16:1 n-7 in MUFA. The ratio of n3/n6, known as characteristic agents of marine fish, was as high as in marine fish but the differences among the tissues were not significant.
Özet
Bu araflt›rmada yukar› F›rat (Karasu) havzas› Yeflildere çay›ndan yakalanan olgun dere alabal›klar› (Salmo trutta macrostigma, Dumeril,1858)’nda farkl› dokular›n›n ya¤ asidi kompozisyonlar› araflt›r›lm›flt›r. Adipoz, gonad, karaci¤er ve kas dokusunda % olarak tekli doymam›fl ya¤ asitleri (MUFA), çoklu doymam›fl ya¤ asitleri (n-3, n-6 PUFA) ile eikosapentaenoik (EPA) ve dokosaheksaenoik (DHA) oranlar› aras›ndaki fark çok önemli (P < 0,01), doymufl ya¤ asitleri (SFA)’nin ise dokular aras›ndaki fark› önemsiz bulunmufltur. SFA içerisinde bulunan en önemli ya¤ asitleri palmitik asit (16:0), steraik asit (18:0) ve miristik asit (14:0) olurken MUFA’da 18:1 n-9 ile 16:1 n-7 ya¤ asitleri ç›km›flt›r. Tatl› su bal›klar› ile deniz bal›klar›n›n karekteristik özelli¤i olarak bilinen n-3/n-6 oran› deniz bal›klar›na yak›n ç›kmas›na ra¤men dokular aras›nda önemsiz bulunmufltur.
